BBC interview on Second Life climate talks

Cafe1.jpg From the BBC radio show Digital Planet:

Bali has not been the only island to host a climate change conference recently.

The science journal Nature has purchased a little archipelago of islands in Second Life called Second Nature.

While participants at the United Nations Climate Change conference in Bali have been agreeing on a roadmap to replace the Kyoto protocol, climate experts – or their representational avatars – have been hosting talks and discussions on one of the Second Nature islands.

Timo Hannay, publishing director at Nature, tells Digital Planet how they went about achieving this series of virtual talks.

The Digital Planet podcast episode with the interview is worth a listen, especially if you're wondering how a conference in Second Life's virtual world stacks up against one in the real word (or First Life, as it's known to enthusiasts) - or against a traditional webcast.

The Second Nature climate conference was announced on CF here; Second Life avatars can visit Second Nature here.

Was the science sidelined in Bali? (updated)

At the end of a gruelling two weeks of talks in Bali, marked by heated arguments, threats of trade sanctions and boycotts, and even tears, a deal was finally reached on how to proceed on climate negotiations over the next two years.

As the talks went into overtime on Saturday, throes of journalists sat it out in the sweltering media tent, waiting for some news of an agreement. And as the minutes ticked by, many involved in the talks feared a deal would not be reached.

But in a historic moment that involved developing countries taking a united stand against the US, who blocked progress over the two weeks of the talks, a deal was agreed to. The memorable moment came when, in midst of discussions on the level of financial commitment required from developed nations on assisting technology transfer, Papua New Guinea's representative, Kevin Conrad said defiantly to the US “If you cannot lead, leave it to the rest of us. Get out of the way”.

The US conceded and joined the consensus. Only a day later, though, and reports are circulating that the US has backtracked on this pledge. White House press secretary, Dana Perino, said it has “serious concerns” about the agreement and that the “problem of climate change cannot be adequately addressed through commitments for emissions cuts by developed countries alone.”

A major dispensation from other nations to keep the US at the table involved the removal of a specific reference to targets for emissions reductions from the preamble. The reference, which was strongly supported by the EU and developing nations, recognised the need for developed countries to have deep cuts in emissions of 25-40% of 1990 levels by 2020. But the final document merely recognized “the urgency to address climate change as indicated in the Fourth Assessment Report of the Intergovernmental Panel on Climate Change” with a footnote to the latest IPCC report.

The footnote refers to tables showing the emissions reductions needed for various stabilization scenarios, including the need to slash emissions by 25-40% to stabilize at 450 ppm CO2e, which scientists regard as being necessary if we are to have any chance of averting ‘dangerous climate change’ or more than 2 degrees Celsius of warming.

Some feel that removal of the numerical reference from the text means that the Bali roadmap lacks substance, whereas others say that what is important here is having an agreement that includes all nations – and that has an end date for negotiations after the current US administration leaves office.

Whether Bali has only succeeded in bringing the world’s largest emitter back to the table at the expense of achieving real emissions reductions remains to be seen.

Coral reefs are on the ropes

coralreef.jpgIf you like coral reefs you should enjoy them while you can, they won’t be around for long. Global warming and the ocean acidification that comes with it will decimate reefs by the end of this century, according to a new review article in Science.

“The impact of climate change on coral reefs is much closer than we appreciated. It's just around the corner,” says study author Ove Hoegh-Guldberg, of the University of Queensland. “... The warmer and more acidic oceans caused by the rise of carbon dioxide from the burning of fossil fuels threaten to destroy coral reef ecosystems, exposing people to flooding, coastal erosion and the loss of food and income from reef-based fisheries and tourism. And this is happening just when many nations are hoping that these industries would allow them to alleviate their impoverished state.” (Reuters ... Telegraph)

Although there is no new original research here, when all the numbers are brought together they are pretty frightening. Atmospheric carbon dioxide will exceed 500 parts per million sometime between 2050 and 2100. This will drive global temperatures up at least 2°C, “values that significantly exceed those of at least the past 420,000 years during which most extant marine organisms evolved” says the paper.

It adds ominously, “Under these conditions, reefs will become rapidly eroding rubble banks such as those seen in some inshore regions of the Great Barrier Reef, where dense populations of corals have vanished over the past 50 to 100 years.”

The story is getting a lot of play in Australia, where the Great Barrier Reef will be one of the most high profile casualties. The Australian, for example, thinks it’s already too late to save. But 2008 will be the year of the reef, so maybe this issue can get some more attention.

“Corals are feeling the effects of our actions and it is now or never if we want to safeguard these marine creatures and the livelihoods that depend on them,” says study author Bob Steneck (AFP).

An just in case you think I’m writing about something that hasn’t come from the AGU ... the researchers will present their results to the meeting this week.

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.

How hot was 2007?

The numbers are in: 2007 (from January till November) has been the 7th warmest year on record, according to the UK’s meterological office. The US National Oceanic and Atmospheric Administration puts it at 5th.

It’s easy to drown in these kinds of statistics, so let’s cut to the chase: the ten warmest years since 1850 have all happened since 1995. If it seems odd to release results for the year’s temperature in November (before the year ends), note that it comes in time to be presented at the UN Climate Change meeting in Bali.

There’s a nice crunching of the UK numbers in The Times, while Reuters rounds up some extreme weather disasters.

Those aware that there was some hyped controversy about records like this a few months ago might like to check out this Real Climate post.

The full report on the climate of 2007 should soon be available on the WMO website.

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.”

*subject to there being no actual numbers in the competition smallprint, as we feel this prejudges the outcome

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

International roaming of the UK carbon footprint

airplane-over-skyscrappers.JPG
According to the Times and the Guardian, a new study led by economist Deiter Helm of Oxford finds that the UK's greenhouse gas emissions have actually risen 19% above 1990 levels, not fallen 15% as officially reported to the UN. The discrepancy comes from the official figures' neglect of emissions from aviation, shipping, overseas trade and tourism, and undermines Britain's image as a world leader in greening its economy.

The study itself (PDF), though, doesn't so much expose hypocrisy as highlight a tough methodological question: should we measure greenhouse gas produced within each country, or should we look at fossil fuel consumption? The UNFCCC required the UK to report only greenhouse gasses emitted within its borders, which have decreased in part because domestic manufacturing in the UK has given way to more imports. The finding of a 19% emissions rise comes from flipping that viewpoint to count emissions associated with goods consumed in the UK, no matter where they are manufactured, as well as the impacts of international aviation and shipping and of UK citizens travelling abroad. Call it international roaming of the country's carbon footprint.

The fact that emissions from international aviation and shipping aren't being counted in anybody's carbon budget at the moment is clearly a problem, and one that may not go away anytime soon -- the aviation industry has vowed to fight against joining the EU carbon-trading scheme.

And if British consumers are effectively outsourcing their greenhouse gas production by buying iPods made in China, where 'production' emissions have been rising, it does the planet no good. Unfortunately, the study takes the tactic of thinking globally but blaming locally. To really understand what consumption-based emissions numbers imply about how to grow a low-carbon economy, don't we need to see the equivalent figures from China - and everywhere else?

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.

Penguins and global warming

adeliepenguinNOAA.jpgIt seems obvious that penguins will be in trouble if global warming continues. If you like it cold and icy then a hotter planet is not going to work in your favour.

A new report from environmental group WWF highlights the problems the dinner-jacketed birds face. “As the ice melts, these icons of the Antarctic will have to face an extremely tough battle to survive,” says Emily Lewis-Brown, Marine and Climate Change Officer at WWF-UK (press release).

WWF says overfishing and a reduction in sea ice is putting the Emperor, Gentoo, Chinstrap, and Adélie penguins under pressure. The report is actually just a two page document timed to coincide with Bali and it has long been known that penguins have, in the words of 2001 paper published in Nature (subscription required), “potential high susceptibility to climate change”.

No new science then, still it’s a good time and a good peg, and it is getting coverage, along with two men dressed as penguins in Bali who danced around to the song “Hot, Hot, Hot”.

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.

Sticker-shocked Rudd backpedals on emissions cuts

Electricalgrid.jpg
Kevin Rudd, the Australian prime minister who won his recent election on a green platform (Nature News - subscription required) and signed Australia onto the Kyoto Protocol as his first act in office, now refuses to support a proposed 25-40% cut on 1990 emission levels by 2020. The worst part: he rejected the cut days after an Australian delegate to the UN climate conference in Bali promised support for it (Herald Sun).

What's holding up Rudd's vision of a greener Australia? A bad case of sticker shock -- specifically, fear of spiking electricity prices. According to the Herald Sun, the Energy Supply Association of Australia has reported that cutting 30% of 2000 emissions levels by 2030 would raise power costs by 30%, and energy industry representatives are telling Rudd that a faster cut would be much more expensive because of current technological obstacles. So it turns out that Rudd is happy to agree to deep long-term cuts whose price tag is harder to predict, but he won't ask Australians to get out their checkbooks in the next few years. For that, he says, he'll need more economic advice.

A BBC survey (PDF) this year found that worldwide, "most people say they are ready to make personal sacrifices – including paying more for their energy – to help address climate change". A whopping 81% of Australians agreed that prices needed to rise -- a majority second to none in the developed world. But like Rudd's long-term emissions pledge, the poll didn't mention any specific price.

How high an electric bill would you pay - and insist that neighbors and businesses pay - to meet the 2020 target?

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….

Earth monitoring: Cinderella science

300px-Mauna_Loa_Carbon_Dioxide.png
This year marks not only the release of a clarion IPCC report and the convening of an enormous UN climate conference, but also the 50th anniversary of the Keeling curve -- the longest continuous recording of atmospheric carbon dioxide levels, revealing a gradually rising carbon dioxide profile that helped trigger early concern about global warming. As part of this week's Earth Observation special (subscription required), Nature has a commentary by Euan Nisbet, atmospheric scientist at Royal Holloway, on the Keeling curve -- which "ranks very high indeed among the achievements of twentieth-century science", he says -- and similar studies in the field of Earth monitoring. Nisbet writes:

Monitoring is science's Cinderella, unloved and poorly paid. Sustaining a long-term, ground-based programme that demands high analytical standards remains challenging. Funding agencies are seduced either by 'pure' notions of basic science as hypothesis-testing, or by the satanic mills of commercial reward. Neither motive fosters 'dull' monitoring because meeting severe analytical demands is not seen as a worthwhile investment. At one stage, Keeling was ordered to guarantee two discoveries per year and today, modern research has become a planned journey through set 'milestones' to deliverable destinations.

What do you think -- how important is this 'Cinderella science' to ongoing climate research and policy, and how could we secure reliable long-term support?

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!

Climate hoaxes and divorced Canadian drunks

While the world’s climate experts meet in Bali, the rest of the world is getting on with the serious business of elaborate hoaxes and stating the obvious. First up: activists from the Rising Tide movement successfully impersonated a major business group and pretended they were going to cut carbon emissions by 90%.

“Leading scientists say decisive action must happen now to reduce our emissions. However, corporate interests have stymied substantive action and are derailing genuine efforts of civil society to adequately address climate change,” says Matt Leonard, member of the movement (press release). Wired has a full interview.

The spoof press release was supposedly from the US Climate Action Partnership, which counts General Motors, Shell, and environmentalists’ bête noire Rio Tinto among its members. Both blogs and news sources were taken in: examples with later retractions at Thomson Financial News (story, correction) and It’s Getting Hot In Here (original, correction).

USCAP issued the following terse statement (reproduced in its entirety):
