One of this year’s Heinz awards – a $100,000 prize for achievement in environmental science and leadership – is going to Chris Field, the Stanford ecologist and leading carbon-cycle expert who became co-chair of IPCC Working Group 2 in 2008. Read more
This week in Nature you can read the first (subscription) of four articles unpicking the business of biofuels. First up is jatropha – the shrub that promised to give drought-ridden countries boundless oil supplies. The reality has turned out to be somewhat different. After a period of hype and over enthusiasm, investments have dried up, somewhat like the promise of oil from arid land. Read more
The Greenland ice sheet melted much more rapidly as a result of warmer temperatures in the recent past than previously estimated, a team of international scientists has revealed. They warn that future warming could have more dramatic effects on the ice than researchers have assumed. The research is from this week’s Nature and there’s a news story about it over at Nature News.

The United Nation’s upcoming climate summit in Copenhagen threatens to get caught in a trap between high expectations and the immense complexity of the task at hand, warns the author of an opinion piece in Nature today [subscription].

Global warming doesn’t just change the weather, it also affects the ozone layer. According to a detailed new modelling study, by 2095 the springtime UV index (UVI) could go up by as much as 20% on the southernmost section of the planet, as altered atmospheric circulation pushes more stratospheric ozone into the Northern Hemisphere. That’s nearly half the UVI increase caused by ozone-eating pollutants in the late twentieth century – but coming from climate change alone. Read more
