Antarctica's warmer past revealed

enviro_35mya2.jpg


With an uninterrupted 17-million year sediment record of Antarctic’s climatic past now available, scientists are hoping for unique new insights into the continent’s climatic past.

A few initial results of the Antarctic Geological Drilling programme (ANDRILL) were announced last week at the general assembly of the European Geosciences Union in Vienna. There is an online news story here.

Antarctica’s ice sheets, so it seems, respond more sensitively to climate fluctuations than has been assumed. During warmer periods, the West Antarctic Ice Sheet and its floating extension, the western Ross Ice Shelf, have shrunk substantially. Some 3.5 million years ago the ice seems to have disappeared completely for around 200,000 years. There were snow-capped mountains, alpine trees, gushing rivers, quiet lakes – the frozen continent was a place where you would love to go fishing or hiking, were it not for the midges.

The world was warmer then than it is today, but not substantially so. If temperatures continue to rise, glaciers in Antarctic’s warmer western part might begin to retreat again before long. A few million years ago, Antarctic melting probably raised sea levels globally by 10 metres or so. If history repeats itself, we’re headed for trouble.

EGU: Keeping an eye on carbon crimes

If there was an eye in the sky keeping watch on our greenhouse gas emissions, what carbon crimes would it reveal?

The ability to measure greenhouse gases from space, soon to become a reality, could answer this question.

Currently, it’s virtually impossible to identify the exact source – and destination - of greenhouse gases, a prominent theme at this year’s European Geosciences Union conference in Vienna.

But, according to scientists speaking today at the conference, this is all set to change within the coming year when two major satellites designed to monitor greenhouse gases will be launched into space.

Due to leave Earth on December 15, the first of these is the Orbiting Carbon Observatory (OCO), a US$300 million-or-so innovation of scientists and engineers at NASA’s Jet Propulsion Laboratory in California. The Japanese version, known as the Greenhouse Gases Observing Satellite, or GOSAT, has an anticipated launch date in January or February 2009.

For a detailed low-down on the satellites and how they will work, see Amanda Haag’s news feature in Nature (subscription) last December. Since then, the scientists have mostly been testing and calibrating the instruments to make sure they work once they’re orbiting the Earth.

Within a year or two, if not sooner, they will enable scientists to identify major sources and sinks or carbon, says Charles Miller, one of the Principal Co-ordinators of the OCO mission. The greenhouse gas measurements taken by the instrument, which will orbit the planet 14.5 times per day, will be three times more precise than any trace gas measurements ever taken from space.

All-in-all, the missions represent an unprecedented effort to collect global climate data from space. While this is fascinating from a scientific perspective, it should also have some interesting political implications by enabling the easy identification of climate culprits.

“If one were to imagine a way to monitor or verify [emissions], then this would be the way to go”, says Miller. For instance, it should quash (or raise, depending on who you’re talking to) fears that nations claiming credits for avoiding deforestation under the Kyoto Protocol will be able to divert the problem elsewhere.

Miller says they often joke that the instrument could detect the greenhouse gas emissions of serious carbon heaveyweights from space. But while the new satellites won’t realistically help reporting on individual carbon crimes, it could act as a ‘big brother’ to keep countries in line with their Kyoto commitments. Personally, I’m curious to know the OCO’s own carbon footprint!

That’s all from me from this year’s European Geosciences Union conference in Vienna. Over and out….

EGU: North Atlantic Ocean may regain status as carbon sink

The North Atlantic Ocean may still be an active storehouse for atmospheric carbon dioxide, said scientists at the European Geosciences Union here in Vienna yesterday.

Following evidence published last year showing that both the Southern Ocean and North Atlantic Ocean have weakened as carbon sinks in the past two decades, the new results suggest that the trend has recently reversed in the North Atlantic.

Scientists have feared that the weakening trend could be a long-term impact of global warming and that it could be typical of the ocean as a whole, which absorbs an estimated 25 per cent of anthropogenic carbon dioxide emissions yearly. If the ocean switches from a storehouse to a source of the greenhouse gas, this would jeopardise efforts to stabilise atmospheric greenhouse gas levels.

Speaking at a press conference at the EGU assembly yesterday, Ute Schuster from the University of East Anglia in Norwich, UK and Christoph Heinze at the University of Bergen, Norway, presented the results of a yearly analysis of carbon dioxide fluxes across the North Atlantic Ocean.

Previously, Schuster and colleagues showed that carbon uptake by the North Atlantic had halved between the mid-1990s and the early 21st century. But further analysis of the data on a year-by-year basis has shown that the uptake of carbon dioxide in the region has been increasing since 2002 and showed an even greater increase, relative to the early 2000s, in 2005.

The researchers caution that the results are preliminary and are not yet published. The coverage was poor in 2006 and they have not yet finished the analyses for 2007, but they say that the results so far indicate that the trend in weakening of the North Atlantic carbon sink is not linear.

The reasons for this variation are unclear. “I personally think we can’t say with confidence that the trend [in weakening sinks] is attributable to [anthropogenic] climate change”, says Schuster. Surface circulation in the North Atlantic has changed in recent years, she says, but these changes could be due to natural climate variability. Specifically, the North Atlantic Oscillation, a large-scale atmospheric pattern that has important impacts on European climate, could be influencing the rate of carbon dioxide uptake.

Post-Bali paradox at UN meeting in Bangkok

ENB_crop.JPGIn Bangkok last week, the first UN climate meeting since Bali wrapped up after struggling til after midnight Friday - not to hammer out emissions targets or controversial new approaches to climate change mitigation, but just to agree on how long to wait before restarting discussions of such matters.

Planned from the start as a meeting to decide what would be decided at future meetings, it was never expected to yield any big breakthroughs. But the hard slog required even to set the work schedule for the next two years worried NGO observers.

“The talks managed to keep the momentum going … but it’s hard to leave Bangkok confident that the deadline can be met,” said Elliot Diringer, director of international strategies at the Pew Center on Climate Change. Marcelo Furtado of Greenpeace Brazil agreed, "If we took all these hours to agree on a workplan, one can only imagine what will happen when the real negotiations take place."

Why so slow? For one thing, the G77 group of developing nations finally dug in their heels against Japan's week-long steady pressure to plan greenhouse gas limits for particular global industrial sectors, in addition to Kyoto-style national targets. Sectoral approaches - heralded recently in Nature Reports Climate Change via this commentary by Glen Peters and Edgar Hertwich and this book review by Gwyn Prins - have the advantage of directly pushing the dirtiest industries to clean up, without leaving less carbon-stringent havens overseas for them to be pushed into. They also distribute mitigation responsibilities to the developing as well as the developed world, something which the US has previously insisted on but which developing countries have warned they cannot afford without more help from the rich North.

An attempt Thursday to summarize the first few days of talks noted emerging views that sectoral approaches could be used to support national targets, though they should not replace them. Made sense to me: sectoral limits could make deep emissions cuts less painful, while national emissions targets maintain a bottom line necessary for keeping the temperature down. But according to ENB, the summary raised a concerned buzz among delegates. That's generally how things were going, though: the day before, ENB had reported that "Some delegates realized that they didn't have a shared vision on a workshop on shared vision."

By Friday, Japan met surprisingly fierce opposition to holding a workshop on sectoral approaches at the next climate conference, to be held in Bonn, Germany, in June. G77 countries, including China, had been pointing to promises from Bali that rich countries would set new national targets and provide mitigation and adaptation funds enabling the South to share the burden of industrial emissions cuts. After wrangling at length, they compromised on a sectoral workshop in August.

The difficulties raise a post-Bali paradox. With the the US back at the table and all eyes on a new deal to dwarf Kyoto, stakes are high. The greater the political will for change, the more there is for each party to gain or lose in the shakeup. We'll see in Bonn whether the cautious rehashing of familiar arguments - typical of first negotiation rounds, as Diringer points out - gives way to actual steps forward.

Can technology stop the world from warming (and my ice-cream from melting)?

AAAS, Boston -

Whether technology can cure the world’s ills has been a hot topic at this year’s AAAS conference.

I joined Alok Jah and James Randerson as a guest commentator on the Guardian’s weekly science podcast yesterday to discuss, among other highlights from the AAAS meeting, whether we can rely on technology as our sole solution to climate change.

We recorded in Toscanini’s ice-cream café in Cambridge, MA, an institution as famous for its clientele (nobel and ignoble laureates and the Dalai Lama), as much as for it’s delectable ice-cream….the wort variety comes highly recommended!

The impetus for our technology discussion was the release of a report at AAAS by a specialist panel convened to predict the great engineering challenges that humanity will face in the 21st century.

A select group of big names and big thinkers, the blue ribbon panel included Larry Page, co-founder of Google, Craig Venter, entrepreneur, geneticist and billionaire, Lord Broers, a former president of the Royal Academy of Engineering and Ray Kurzweil, futurologist, software engineer and alleged recipient of some 14 honorary doctorates.

Kurzweil sees no end to the possibilities of what technology can achieve this century – from creating artificial intelligence to match the human intellect to reversing the signs of aging. His basis for these assertions is the rate at which technology is advancing – a doubling every two decades. Though this may sound modest, its cumulative effect is worth contemplating – that’s 32 times more technical progress over the next 50 years than there has been in the past half-century!

The views of the panel are positively circumspect in comparison to Kurzweil’s, though are none-the-less fascinating.

AAAS: Lost in Translation [updated]

Correction Appended

AAAS, Boston-

One of the most interesting, and popular, sessions I’ve been to so far at AAAS was the panel discussion on how the media communicates climate change.

Though there wasn’t any news in the talks about news by various well known science communicators, the room was packed to the rafters and the lively discussion spilled over into the next session.

Andy Revkin of the New York Times , who recently started the excellent Dot Earth blog, spoke of the tyrannies of news and the difficulty of getting climate-related news on the front page without a peg like Hurricane Katrina. He also pointed out that the more complex a story is (as is so often the case in climate science), the less space it gets.

Matt Nisbet, who runs the Framing Science blog, talked about how sources of information frame people’s perceptions of the issue, with the example that Gore’s ‘climate crises’ gets referred to more frequently by the media than the IPCC, NOAA or NASA.

David Dickson, director of Scidev Net warned that journalism is at risk of losing its independence and becoming a voice for various NGOs, as they become increasingly strategic at media relations. Some NGOs apparently paid for a large contingent of journalists to attend the UN conference on climate change in Bali, with the explicit understanding that they would cover their stories*.

John Holdren, director of the Woods Hole Research Centre, aired his frustration at various aspects of how climate change is reported by the mainstream media, including references by journalists (other than Revkin) at the NYT to “global warming, [which] is caused by humanity, as many scientists believe”.

Holdren has been trying convince journalists to use ‘global climate disruption’ rather than the misrepresentative ‘global warming’. Good luck to him – it would up the word count, and, as we've heard, there just ain’t no space for that.

Yesterday morning, I took part, with a national environment reporter from a popular broadsheet, in an interview on how journalists communicate climate change. The interviewer was a grad student from MIT who is doing her PhD on the topic. She asked me a lot of questions about sources of information - the issue of NGOs came up again and also the question of where to draw the line with quoting scientists on policy recommendations. The differences between us and a national paper were very interesting - I get way less bumf from NGOs, for a start!

*Dickson has since clarified that the agreement was that journalists would cover the conference rather than the activites of the NGO at the conference.

AGU meeting: Jim Hansen bites back

American Geophysical Union meeting, San Francisco -

Turns out that Jim Hansen, the outspoken NASA climatologist, didn’t attend John Marburger’s talk on Monday night, in which Marburger (who is President Bush’s science advisor), called accusations of censoring US climate scientists ‘ignorant’.

Hansen, who has long gone public with his thoughts about the problems of human-caused global warming, has said in the past that NASA public-affairs people censored his public speeches and media interviews to play down the risks of climate change. On Monday, Marburger charged that such accusations were baseless, saying that he personally had tracked down each claim and found it to be wanting. Marburger didn’t mention Hansen by name, but the subtext was clear to everyone in the audience.

Asked for his response today, Hansen simply pointed to a new book called Censoring Science: Inside the Political Attack on Dr. James Hansen and the Truth of Global Warming. (I haven’t read it and thus can’t recommend it, but here is a link so you can see at least what it looks like.) According to Hansen, it details a systematic effort to suppress climate scientists such as himself.

Asked if he had ever spoken to Marburger about the issue of censorship, Hansen said simply: “Not about this.”

Hansen isn't just confining his criticisms to US leadership, though. He's got a draft letter in the works to UK prime minister Gordon Brown and the German chancellor Angela Merkel, criticising the planned construction of coal-fired power plants in their countries.

Asked today why he was focusing on these leaders when China is constructing a coal-fired power plant at the rate of nearly one per week, Hansen said he feels that the developed world needs to take responsibility, as it has been the source of the majority of carbon dioxide emissions up until this point.

AGU meeting: The outlook for the Arctic

American Geophysical Union meeting, San Francisco -

News from the Arctic just continues to get worse. A fair number of presentations here have been dealing with the dire 2007 conditions for sea ice and the Greenland ice sheet.

First up, Greenland. Last summer, more ice melted atop Greenland than ever before measured, adding to a consistent downward trend of some 135 gigatons of ice disappearing per year. Marco Tedesco, of the Goddard Space Flight Center in Maryland, told the meeting that surface temperatures in Greenland were four to six degrees Celsius warmer than usual this summer, which helped accelerate melting, particularly at high latitudes.

The situation is even more precarious for sea ice. A couple of researchers here have been tossing around dates like 2012 or 2014 for estimates of when the Arctic might be completely ice-free in summer. While these sorts of numbers are pretty arm-waving at the moment (numbers like 2040 were previously considered to be aggressive), there’s little reason to think the situation will get better in the next couple of years. Mark Serreze, of the University of Colorado, spent a keynote lecture on Tuesday showing images of Arctic ice shrinking like a snowman left out too long in the sun. In September of this year, sea ice covered just 4.2 million square kilometers - by far the lowest record ever.

And the ice isn’t only shrinking in extent – it’s also thinning. Don Perovich, of a US army cold regions and research laboratory in New Hampshire, reported on a single but extraordinary ice buoy in the Beaufort Sea. In June the buoy measured sea ice at that location as 3.3 metres thick – “really a healthy piece of ice,” as he put it. But by the end of the summer, 70 centimetres had melted off the top – and 2.2 metres (yes, metres) off the bottom.

When you see those dramatic maps of the Arctic ice extent shrinking over time, don’t forget that it’s also thinning – a complicating factor that may just make things worse in summers to come.

AGU meeting: What the president's science advisor says about climate change

American Geophysical Union meeting, San Francisco -

What a difference a year makes. Last AGU meeting, the evening keynote lecture was by Al Gore. This AGU, Gore was in Oslo, having picked up his Nobel Peace Prize for his climate activism, on the same day President Bush's science advisor John Marburger was giving a lecture here on climate change.

Gore got a standing ovation from the AGU scientists. Marburger got a slew of hostile questions. He probably should have expected this, given the Bush administration's policies on climate change. And lines like "scientists have lost credibility in this debate" didn't help either.

Marburger spoke for about 45 minutes on US climate policy, reinforcing many of the same messages he's put out there before. Bush recognizes the significance of climate change, Marburger argues, and has been saying as much since June 2001. The US is doing plenty to move towards taking action, including hosting a summit of major emitters in September and adopting 'aspirational' goals to improve energy consumption and develop new technologies to deal with it. Too much emphasis is being placed on mitigiation strategies for reducing carbon emissions, instead of adaptation strategies to get people to live differently in a greenhouse world.

Such messages did not go down well with the audience. Questioners pressed Marburger on mandatory emissions caps for US industries (ask Congress, says Marburger); alleged censorship of climate scientists (not a word of truth in it, he argues); and Bush's refusal to move the Kyoto protocol forward (Congress would have stymied it anyway).

Marburger also included a plea for people to read the details of the IPCC technical reports issued this year, not just the policymakers' summaries. Only in the technical reports, he argues, are the details and the complexity that everyone needs to understand in order to make informed decisions about what to do about climate change.

No one's arguing with that. But surely he hadn't forgotten that his very audience was made up of many of those who wrote the IPCC technical reports in the first place -- and they still don't agree with him.

Gore urges delegates to bypass Bali roadblock

Bali, Indonesia-

In the disabling humidity of Bali, former US vice president Al Gore last night urged delegates gathered here at the UN conference on climate change to continue efforts towards an international climate change deal, despite attempts by the US delegation to stall progress.

Gore said, to loud applause, that the US was “principally responsible for obstructing progress” at the UN conference, which aims to set out an agenda for how negotiations on a replacement for the Kyoto Protocol should proceed over the next two years.

Delegates have now reached agreement on a number of key issues for the ‘Bali roadmap’, including reducing deforestation, providing financial assistance for adaptation and transferring technology to developing nations.

But there are fears that the science that has informed the process is now being sidelined.

The main bone of contention is how the most recent findings from the Intergovernmental Panel on Climate Change, which shared this year’s Nobel Peace Prize with Gore, will be acknowledged in the final text agreed to in Bali.

Most delegations believe that the text should refer to the need for developed nations to reduce emissions by 25-40% on 1990 levels by 2020. But the US says that to do so would be ‘prejudge the outcome’ of the process. Japan and Canada agree with the US and Australia agreed with this stance earlier in the week, though it’s position is a little less certain at the moment.

The EU is standing strong behind the need to include specific numbers on future emissions reductions, arguing that it would be pointless to agree on a roadmap without a destination. “It is crucial for us that we must have an idea where we are heading to – it’s not only to science to show us the destination, but the destination must be consistent with the science”, said Portuguese secretary of state for the environment, Humberto Rosa yesterday in Bali.

European commissioner Stavros Dimas warned US under secretary of state Paula Dobiansky in a meeting yesterday morning that unless a substantive agreement was reached in Bali, there would be little point in the EU attending the Major Economies Meeting to be hosted by the US in February in Hawaii. Rosa and Dimas said this was not a threat, but an acknowledgment of the fact that the Major Economies Meeting is designed to feed into the UN process.

In his address last night, Gore advised negotiators to move beyond their anger and frustration at the US and to recognize that a new US administration, which will take over from Bush in little over a year, will likely embrace more climate-friendly policies.

"Do all of the difficult work that needs to be done and save a large, open, blank space in your document and put a footnote by it [that says] this document is incomplete, but we are going to move forward anyway."

But this morning, executive secretary of the UN’s Framework Convention on Climate Change, Yvo De Boer, said that option would be unfeasible.

“It would be impossible to advance here without the US, as this is a consensus”, said De Boer. “It doesn’t make an awful lot of sense to craft a climate change regime without one of the major economies and the major emitter”.

Al - and an altercation

Bali, Indonesia-

Olive is about to fill you in on the content of Al Gore's speech tonight, so, refreshingly honest as it was, and as much as I and many others enjoyed this:

“I am not bound by diplomatic niceties. My own country is principally responsible for obstructing progress here in Bali…but not the only one that can take steps to ensure we move forward”

I won't duplicate. In fact, it was an unscheduled side event that I found rather entertaining – and possibly more enlightening with respect to the ongoing negotiations. With difficulty, I’d found a seat from which to watch Gore’s speech, but several latecomers weren’t so fortunate, which led to a little altercation in the row in front of me.

Several conference attendees had taken seats for themselves and reserved some for colleagues who were hot-footing it to the plenary hall, when another from a different delegation (have a guess - it's not the most obvious - answers on a postcard, 25-40% off your next, er, ten years of emissions for the first correct answer*) swooped in and took a place smack bang in the middle. A good-natured squabble ensued, but with both parties getting gradually more annoyed, and ending with a schoolroom-worthy outcome: the single man refusing to budge, and everyone else talking about his rudeness behind his back, but so he could hear every word.

If what was going on behind the doors of the closed negotiations was anything like this, then no wonder many are finding the inch-by-inch progress frustrating, and no wonder Yvo de Boer opened the press conference this morning with the words: “I am very concerned about the pace of things.”

Deforestation a ‘thorny’ issue at the Bali talks

Bali, Indonesia-

As anticipated, deforestation has emerged as something of a thorny issue at the UN conference on climate change, currently nearing a close in Bali.

It was announced yesterday that measures to avoid further destruction of tropical forests, such as the Amazon, will be included in the agreement to come out of the talks at the end of this week. The Bali agreement is expected to act as a guideline for negotiations on an international climate change deal up until the end of 2009.

Daniel Nepstad of Woods Hole Research Centre, US said today in Bali that the Amazon rainforest is expected to see a 55% dieback by 2030 through deforestation, logging and drought. Rainforests in other nations, such as Indonesia are facing similar pressures. So, any effort to avoid deforestation, which accounts for an estimated 20-25% of global greenhouse gas emissions, is to be commended. But the solution being put forward to in Bali , known as REDD - Reducing Emissions from Deforestation and Degradation, is being met with opposition on many sides.

REDD protests.jpg

Under the proposed scheme for ‘avoided deforestation’, carbon sequestered by forests in developing countries that are not being cut can be traded on the carbon market, where developed countries can buy the credits and ‘offset’ them against their own emissions targets.

A draft text on deforestation is ready to go forward for discussion by the high level ministers, who arrived at the Bali conference today, said executive secretary of the UN conference on climate change, Yvo De Boer.

Countries such as Indonesia and numerous conservation NGOs are celebrating inclusion of the scheme. And given that emissions from deforestation were omitted from the Kyoto Protocol, it is the first such international effort of its kind.

But much remains to be agreed upon. The issue of whether such a scheme should include forest conservation is a remaining “bone of contention”. As reported in the Hindustan Times, the Indian delegation wanted to add 'conservation' to 'avoided deforestation' , owing to the fact that India is one of the few developing countries where the forest cover is going up, not down. “We should not be penalised for that” said secretary of the ministry of environment and forests, Meena Gupta

An audience with the UN Secretary-General - and some rather general statements

Bali, Indonesia -

There was a chance today for journalists to hear from Ban Ki-moon, Secretary-General of the UNFCCC, at a lunchtime press conference usually given by the (often batik-shirted) Yvo de Boer. This conference has so far been a useful purified daily dose of what’s been going on behind closed doors in the Bali meetings.

But today’s was a bit of a disappointment. Although the beginning of Ban Ki-moon’s speech was suitably rousing – “Today we are at a crossroads – one path leading towards a comprehensive new climate agreement and the other towards a betrayal of our planet and our children” - from this point on it felt as if (to bleed the analogy dry) he got a bit lost.

The questions he faced were fairly predictable – but the answers frustrating and woolly. When asked about his view on emissions targets for particular countries, he replied: “There are differences of opinion between developed and developing countries, and even among these groups”.

In contrast, I got the distinct impression that was no difference of opinion among many of the journalists in attendance. Many thought it was all a bit watered-down. That view was epitomised by one question asked of him at the end: if all countries have already agreed to formal negotiations, and the purpose of this meeting isn’t to go any further and define targets and talk numbers, have we achieved what we wanted? Shall we all just go home?

“We need to expedite our process of negotiation”, he said halfway through – but I couldn’t help feeling that if the high-level negotiations going on this week are proceeding at the same swimming-through-treacle pace as this press conference, he would have a hard time expediting anything.

Coughing up the cash

Bali, Indonesia-

Whether we can avoid the worst consequences of climate change will ultimately be determined by whether we are willing to finance it.

Finding an effective means for financial assistance and investments to flow from north to south could be a make or break issue at the UN conference on climate change here in Bali, where delegates from almost 190 nations have convened to agree a ‘roadmap’ for an international climate agreement to follow the Kyoto Protocol in 2012.

NGOs and delegates from the world’s poorest nations, some of which are already beginning to experience the harsh affects of a warming climate, are calling on developed countries to boost funding to help them adapt, and to transfer technology that will help them green their economies.

Under the Kyoto Protocol’s ‘Adaptation fund’, a paltry $163m has been pledged by rich donor countries to developing nations, and just $67m of this has actually been delivered. Yet the sum actually needed to finance adaptation and capacity building in the south is in the region of several tens of billions of dollars, according the World Bank (and reported by the Associated Press). Oxfam says that the very poorest nations also need an up front payment of $1-2bn immediately to address urgent adaptation needs.

The fund, which will finance projects such a building sea walls and irrigating crops, is currently derived from a 2 percent levy on revenues generated by the Clean Development Mechanism, the scheme that allows industrialized nations to pay for carbon credits produced by emissions-reduction projects in the developing world and credit then against their own emissions targets. But it now looks as though the UN will have to expand its funding for adaptation, potentially through a direct tax on emissions.

The transfer of clean technologies to developing nations is another goal of the Kyoto Protocol that has clearly not been met. In part, this is owing to lack of funding from the public sector and a lack of interest from the private sector, says Yvo De Boer, executive secretary of the UN framework convention on climate change.

The solution, says De Boer, will require the creation of investment potential through mechanisms such as the carbon market that can send a clear price signal to private investors, who are expected to fund 86% of future clean energy technology projects in the south. It will also require “intelligent financial engineering, to make public and private money go where it has never gone before” akin to “embarking on a star trek expedition”, says De Boer.

A group of finance ministers is now trashing out the details in side meetings at the Bali talks. By the end of the conference, it should be clear whether the worlds’ richest nations are willing to cough up their portion of the much needed cash.

Interview: Rajendra Pachauri in Bali

Bali, Indonesia-

Pachauri_Bali

A group of scientists from the estimable Intergovernmental Panel on Climate Change yesterday presented ministers of more than 180 nations in Bali with the overwhemling evidence on climate change. I caught up with IPCC chairman Rajendra Pachauri after the event to get his take on the state of play in Bali…and beyond.

Since being awarded the Nobel Peace Prize together with former US vice-president Al Gore for their work on climate change, the IPCC has become something of a household name and Pachauri, or ‘Patchy’ as he is known to friends, has come as close to celebrity as is possible in science. With the recognition comes constant requests ...not least for interviews from pushy journalists, I imagine.

We meet in the lobby of the palatial Aston Bali Resort and Spa, where during our brief meeting, he is stopped and congratulated by vitually every passer by. He humbly reminds his admirers that the winning work was that of the many hundreds of scientists who make up the UN body on climate change.

I query if he ever tires of the praise, but he admits that he’s a sucker for it…and says it’s unlikely to last longer than a few weeks anyhow. If anything, he seems to take from it a renewed vigour for communicating the urgency of global warming, a task at which he is certainly adept.

The IPCC has been assessing the status of climate change for nearly 20 years and this November issued a synthesis report, the result of almost two years work that acts as a primer on the scientific understanding of climate change.

The synthesis is not merely a summary of the three latest reports released by the panel in the first half of 2007, which each give a detailed discourse on the science, impacts and options for dealing with climate change, respectively. In addition, the neat 23-page document clearly sets out the consequences of various courses of action. The IPCC presentation at the plenary session here in Bali brought that work formally into the UN negotiating process.

Notable at this round of UN talks on climate change, the 13th conference of its type, no-one is questioning the science. A few lonely looking sceptics can be seen outside handing out flyers and openly admitting ‘We’re the least popular people here”.

Pachauri believes that winning the Nobel Peace Prize has convinced people of the magnitude of the issue. “It brings home that climate change is an issue that affects the future of humanity and a dimension that people haven’t really thought about previously – if we don’t deal with this in time, it could become an issue of peace and national security”, he says.

Major emitters: binding cuts crawling off the table in Bali

Bali, Indonesia-

The chances of the world’s major emitters agreeing to mandatory emissions reductions are becoming an increasingly unlikely outcome of the UN talks on climate change here in Bali.

“Nothing has been ruled out yet”, said Yvo de Boer, secretary of the UN Framework Convention on Climate Change (UNFCCC) today in Bali, but he described the possibility of binding emissions cuts for developing nations such as China and India as “crawling towards the edge of the table”.

China has been receiving praise for its proactive role on addressing climate change and its willingness to enter into talks on a post-Kyoto agreement, but De Boer said that India has not been at the forefront of the discussions this week in Bali.

Both India and China have introduced strategies to mitigate climate change this year in a notable departure from historic concerns that to do so would threaten economic growth. Rajenda Pachuari, chairman of the Intergovernmental Panel on Climate Change, said that neither China nor India has had sufficient time to act on climate change since introducing their respective strategies and expects that they will demonstrate more significant efforts in the coming months.

In the meantime, NGOs are hoping that the passage of two climate relevant bills through the US House of Representatives this week will put increasing pressure on the Bush administration to sign up to binding emissions targets.

First up is the Energy Bill, which is the only piece of legislation in over 30 years to require a rise in vehicle fuel efficiency. Designed to improve energy security while reducing emissions for transport, the bill would raise fuel economy by 40% by 2020. Second is the Liebermann-Warner Climate Security Act, which would cut emissions from the power and industrial sectors by 70% by 2050 relative to 2005 levels.

The passing of these bills sends a clear signal to the world that the political centre of gravity in the US has shifted on global warming, but all signs indicate that domestic policy is unlikely to sway the stance of the US on the international front.

Both bills have yet to pass through the Senate and White House, and President Bush has already threatened to veto them. But according to Angela Anderson of the National Environmental Trust in the US, this would be rather ironic given that these are exactly the kind of measures that other major emitters have enacted into their own legislation - the very nations that the US is currently engaging with a serious of talks parallel to the UN process.

Yesterday, Harlan Watson, head of the US delegation, said that neither the passing of these acts to limit US domestic emissions nor the move by Australia to ratify Kyoto would change their stance in Bali. "We're not changing our position," he said.

Given that the US is the only nation that appears to be cutting its fossil fuel emissions, while those signed up to Kyoto have failed to meet their targets, some say that binding cuts may not be the way to go after all.

Scientists speak out in Bali

Bali, Indonesia-

For the first time this week at the UN conference on climate change, scientists today sounded their views on the specifics they believe the road from Bali should lead to if we are to avoid catastrophically changing the climate.

Signed by more than 200 of the world’s most eminent climatologists, the ‘Bali Climate Declaration by Scientists’ issues a stark warning to negotiators that unless they take immediate, bold action on reducing greenhouse gas (GHG) emissions, many millions will be at high risk of some of the most sinister effects of global warming including extreme sea level rise and increased drought and heatwaves.

“This declaration makes a clear and unambiguous statement about what our emissions targets have to be. To achieve these targets, we need action now, this week, here in Bali, said Matthew England, climate modeller at the University of New South Wales, Australia.

Specifically, the document states that atmospheric GHG concentrations need to be stabilised long-term at 450 ppm CO2e (carbon dioxide equivalent) or lower to keep global temperatures from rising by more than 2 degrees Celsius. Formally announced at a press briefing in Bali this morning, the declaration calls on governments to reduce emissions “by at least 50% below 1990 levels by the year 2050”.

Though the science is taken from the latest report from the Intergovernmental Panel on Climate Change (IPCC) and the signatories comprise the most prominent IPCC authors, the policy-prescriptive statement is distinct from the UN process which assesses the current understanding of climate change. “This is simply outside the charge of the IPCC process”, said Richard Somerville, meteorologist at Scripps Institution of Oceanography at the University of California, San Diego.

Not all of those invited signed. England, one of the coordinators of the declaration, reckons they had at least a 70% success rate with getting authors on board. According to Andrew Pitman, a climate scientist also at the University of New South Wales, Australia, some authors didn’t sign because they felt the emissions cuts called for were simply not tough enough.

The declaration advises stabilising at 450ppm CO2e, yet this would only give us a 50% chance of avoiding dangerous climate change, explained Pitman. To increase that chance to 75%, we would need to bring atmospheric GHG levels down to 400ppm CO2e. With emissions steadily increasing, the urgency of the situation is brought home by the fact that we are now at GHG levels close to those at which the scientists recommend we stabilise.

Developed nations party to the Kyoto Protocol agreed in Vienna in August that emissions should be cut by 25-40% by 2020, based on 1990 levels. England confirmed that the target announced today is in line with this figure.

But the scientists won’t go as far as to say when the targets should be implemented or how nations should go about reducing their emissions. “We don’t have recommendations for how the negotiations should proceed”, said Somerville. He added that there is no magic bullet and that all approaches to reducing emissions will need to be considered.

As for whether their recommendations are likely to be taken on board, it’s probably too early to say. Diana Liverman, climate policy expert at Oxford University, UK and signatory of the statement, said that she hasn’t seen any evidence of the talks derailing yet and that a consideration of stricter targets than those under Kyoto may come next week.

On being asked for his response to the consensus document, US Senior Climate Negotiator Harlan Watson said that he wasn’t aware of it. He added that the US administration wholly approved of the IPCC, but that they wouldn’t endorse any specific scenarios from the latest report.

The IPCC will present their synthesis report at the plenary tomorrow morning – watch this space….

Rocky start to Bali relationship

Bali, Indonesia-

The road to building a Bali roadmap was looking increasingly rocky today, as the vastly differing expectations of what will emerge from the two weeks meeting of the 13th conference of parties (COP) to the UNFCCC became increasingly apparent.

One of the biggest bones of contention, of course, is whether the roadmap will include an agreement on the need for binding emissions targets from 2012, which signals the end of the second period of commitment of the Kyoto Protocol.

At the opening plenary talk on Monday, Yvo de Boer, UNFCCC Executive Secretary said that “A marriage contract is not something to discuss on a first date”, eluding to the fact that the willingness of nations to co-operate must first be established here before they get down to the nitty gritty of asking parties to act on their promises.

But many feel this is a COP-out. Today, Matthias Duwe of Climate Action Network, a worldwide association of some 400 NGOs, retorted to De Boer’s comment, saying “These parties have been dating for over 15 years now, so we’re not exactly on a first date here”.

Duwe is one of many who believe that a process without an end date and without specific substance will be insufficient for the enormity of the task at hand.

But others feel that pushing for targets now will rock the boat…and possibly capsize it.

Meena Raman of Friends of the Earth International basically agrees with De Boer. She believes that there needs to be more evidence of good will from industrialised nations before we can reach that point. “To put the targets on the table right now would be going in the wrong direction”, said Raman.

There’s also the argument that you need to have the right tools for the job, lest we (again!) agree to targets we fail to meet.

De Boer compared setting targets first to being asked to swim across the Atlantic without knowing whether you’d have a team, be allowed breaks, use rescue equipment etc. Basically, you’d hardly sign up for the task without knowing the details beforehand.

This approach, however, would be a flip on the order in which the Kyoto Protocol was agreed, which set targets first and then looked at how to achieve them. And that’s bound to ruffle feathers.

Among all the political wrangling and finger pointing, there has been some light hearted relief takes on the Bali talks, such as the giant thermometer erected by Greenpeace outside the conference venue and the Fossil of the Day Awards announced each evening by the Climate Action Network. The prize is in recognition of the efforts of countries that block progress at the conference.

Yet again, Saudi Arabia won first prize today for complaining that the protocol has an unfair focus on CO2 (and then called for prioritisation of CCS, which is concentrated on CO2). And secondly, for saying that article A "should not attach an economic element to the noble cause of fighting climate change"--when for years, they have been trying to undermine the fight against climate change specifically by campaigning by alleging adverse economic effects!

UN climate conference sees diverse opinions emerge

Bali, Indonesia-

The second day of the UN conference on climate change has seen some diverse opinions emerge on what the immediate priorities should be for a 'Bali roadmap'.

Environmentalists claimed today that a group of obstructionist nations, including Saudi Arabia, Canada, the US and Japan, was forming against binding emissions targets.

Steven Guilbeault of Environmental NGO Equiterre cited Canada’s “abandonment of it’s targets under the Kyoto Protocol” and Japan’s statement today that it is time to move away from a Kyoto approach to addressing climate change as reasons for their inclusion.

“Canada and Japan are saying nothing about legally binding emission reductions after 2012," said Guilbeault.

UNFCCC Executive Secretary, Yvo De Boer said that although Saudi Arabia had expressed concern about whether the time is right to enter formal negotiations, no other nation has openly backed this stance in Bali. Though that’s not to say that others don’t agree.

Describing the mood today in Bali as “mixed”, however, De Boer said that there was a clear divergence of opinion between industrialised and developing nations on where the focus should now lie. Whereas developed nations are honing in on the long term goals for addressing climate change, many developing nations are concerned that this will diverge attention from the need to address immediate priorities, such as establishing a sufficient fund for adapting to climate change and transferring technologies from developed countries, objectives which have not been realised under the Kyoto Protocol.

A open ‘special group’ was established today to address these issues and others that will shape the Bali roadmap, including whether the negotiations up until 2009 will include targets and measurable objectives, or will comprise a looser period of informal dialogue that could faciltate buy-in from major emitters such as the US, China and India.

One thing is clear: as of yet, there is no consensus on what shape the roadmap will take; for now the son of Kyoto is still gestating.
