Project Surya Aims to Clear the Air and Reduce Global Warming

Welcome to Blog Action Day 2009!

For me, the choice was easy – I write about science, so of course I’ll blog [...]

India is Vulnerable and Acting to Address Climate Change

“India is vulnerable,” said Jairem Ramesh, India’s Minister for Environment and Forests at a breakfast meeting in Washington, DC last week. “We are responding to climate change because it is in our own self-interest.” While the U.S. Chamber of Commerce sheds members over its reactionary position on climate change, the US-India Business Council (USIBC), headquartered [...]

Paleoclimatologist Lonnie Thompson has spent more time above 20,000 feet than anyone else. In the 1970’s, he was the first scientist to retrieve ice sample from a remote tropical ice cap and analyze them for ancient climate signals. Until then, scientists had only studied polar ice cores. But “polar glaciers only cover 10% of the [...]

The Northwest Passage: a Shortcut to Greater Arctic Warming

The thermometer will hit upper nineties again today in Washington, DC., but it’s been a pretty mild summer until now – in fact, July was slightly cooler than average. That wasn’t the case up north, way up north, in Tuktoyaktuk, Northwest Territories, Canada. In this seaside town 1,500 miles north of Seattle and well within [...]
