Bangladesh’s battle with climate change

Bangladesh’s battle with climate change

As a vast, flat delta, Bangladesh is perhaps the country most clearly associated with the threat of rising seas – without protective barriers along the coast, even a moderate increase in sea level could cause flooding deep inland. Estimates suggest that even a one-metre rise could swallow 15 to 20 per cent of the land area, where some 20 million people reside.  Read more

Ackerman: Odd-couple match for Lomborg?

Ackerman: Odd-couple match for Lomborg?

More than two years have passed since Nick Stern’s report on the economics of climate change was published, yet the question of how to weigh the costs against the benefits of acting on climate change – and whether such an approach in even ethical – is still being hotly debated. Stern’s adherents, on the one hand, support the stance of the former World Bank economist who argues that taking strong, early action on climate change outweighs the costs of doing nothing, or of delaying action. On the other hand, some of Stern’s detractors – most notably ‘skeptical environmentalist’ Bjorn Lomborg  … Read more

Storm over planned ocean fertilization experiment (updated)

Storm over planned ocean fertilization experiment (updated)

Stimulating algal growth by adding iron to nutrient-poor ocean regions is one of several geo-engineering methods that could possibly mitigate greenhouse warming. But given widespread worries about possibly harmful side-effects on marine life, large-scale ocean ‘fertilization’ is currently not considered advisable.  Read more

Rapid retreat of Greenland’s outlet glaciers may be temporary

The loss of ice from Greenland ranks as one of the most troubling, and poorly understood, aspects of climate change. Melting of the colossal ice sheet, which is already undoubtedly underway, has the capacity to raise global sea levels by an astounding 7 meters.  Read more

Nature: Reforesting India

Planting trees seems like a cheap and easy way to pull carbon dioxide out of the atmosphere while improving land and soil stocks that have been degraded over the decades. The international community recognized as much when it included reforestation in the Kyoto Protocol more than a decade ago.  Read more

Adaptation needed to avoid world food crisis

Adaptation needed to avoid world food crisis

The recent food crisis, which saw crop prices sky rocket in 2007/08, demonstrated the fragile nature of the world’s food system. Coping with the short-term challenges of food price volatility is daunting, but the longer-term challenge of avoiding a perpetual food crisis due to global warming could be far more serious.  Read more

The Greening of Christianity

The Greening of Christianity

With a new year comes a new version of the Bible. Well not exactly new, but fairly recent. This past summer, Harper Bibles published an eco-friendly version of the Bible known as The Green Bible . In addition to being printed on recycled paper using soy-based ink, The Green Bible highlights all the passages that encourage people to care for the Earth in, of course, green ink. While the verses themselves are not new (the text comes from the New Standard Revised Bible), the focus on the Earth is. And this version also includes an introduction from Archbishop Desmond Tutu, as well as essays by prominent theologians and information on how to get involved.  Read more

New Antarctic base could help extend climate record back 1.5 million years

New Antarctic base could help extend climate record back 1.5 million years

A Chinese expedition is expected to start work this week on a new Antarctic base that will faciliate novel research in climate science as well as in other fields, reports Jane Qiu over on Nature News [subscription]. The Kunlun base will be located at Dome Argus, or ‘Dome A’, some 4,093 metres above sea level. It will be China’s third Antarctic research facility and is being built as a legacy of International Polar Year, a major two-year scientific programme that comes to an end in March. According to radar studies of the region, Dome A sits atop ice over 3,000  … Read more

Geoengineering: Plan B or not plan B?

With serious talk about geoengineering options now on a serious roll (“Not so sotto voce any more” is how RealClimate put it back in August) 80 climate researchers have been polled by the Independent about whether we should prepare techno-fixes such as ocean fertilization or aerosol clouds as an emergency lever on the Earth system.  Read more
