-The Hindu     The Earth is now in uncharted territory as atmospheric carbon dioxide has shot past the 400 ppm mark. There is no more room for manoeuvre When Brian Lara scored a scintillating 400 not out in Antigua in April 2004, it seemed his score would remain unchallenged for the foreseeable future. But we now have another player on the scene who has scored 400, and threatens to go past that number...

-The Hindu THE SUNDAY STORY An analysis of the output from 18 different global climate models indicates that India’s average annual surface air temperature could go up by between four degrees Celsius and seven degrees Celsius by the end of this century. The warning signs are already out there. Global air and ocean temperatures have risen in response to human-driven emissions, particularly of carbon dioxide. Oceans have become more acidic and the...

-The Hindu THE SUNDAY STORY The scientific evidence points to a warming world. That would affect human health and agriculture, but at the Climate Change Conference in Doha, many rich countries baulked at strong action. India and China lead the developing world in calling for more remedial funding. The World Meteorological Organization (WMO) times the release of its provisional annual statement with the U.N. climate negotiations. This year, it dwelt on the...

"What's missing from the models used to forecast sea-level rise are critical feedbacks that speed everything up," says Bill Hay, a geologist at the University of Colorado, US. The feedbacks include...

-Outlook Could scientists have got the impacts of climate change on food supply wildly wrong? I believe we might have made a mistake: a mistake whose consequences, if I am right, would be hard to overstate. I think the forecasts for world food production could be entirely wrong. Food prices are rising again, partly because of the damage done to crops in the northern hemisphere by ferocious weather. In the US, Russia...
