8:25 PM | Study Finds Genetic Clues to How Plants Adapt to Climate
Using supercomputers to analyze hundreds of thousands of genetic markers in a thousand plant samples, scientists say they have found how a common weed uses its genetic code to adapt to changes in its environment such as freezing temperatures and drought. The findings add to our knowledge of how plant life evolves, and could be used to help breed crops that are more adaptable to climate change, the researchers say.

10:00 PM | U.S.-India Climate Agreement Less Substantive Than U.S.-China Climate Deal
The U.S.-India climate agreement announced January 25 creates a new agreement between the second- and third-largest emitters of greenhouse gases in the world but does not have the strength of the U.S.-China climate deal reached last year. Rather than committing India to cap its emissions, the U.S.-India deal called for “enhancing bilateral climate change cooperation”…

4:24 AM | January Woolly Bear Catepillar
Washington State is enjoying San Diego-like weather. This has been particularly true above the lowlands where cold air tends to settle. On Monday, Bob and I investigated a debris flow which entailed making our way up a steep drainage to a ridge summit at 2,800 feet. It was a very steep climb.  During a short break we found ourselves in a small cloud of mosquitos at 2,000 feet. Just below the summit ridge we came across this woolly bear caterpillar.  Bob noted […]

Why the Arctic is climate change’s canary in the coal mine The Arctic may seem like a frozen and desolate environment where nothing ever changes. But the climate of this unique and remote region can be both an early indicator of the climate of the rest of the Earth and a driver for weather patterns across the globe. William Chapman explains why scientists often describe the Arctic as the “canary in the coal mine” when it comes to climate change. View full lesson: […]

10:29 PM | Squirrels’ role in climate change puzzle
Alaska’s North Slope is home to Arctic ground squirrels. Near the Atigun River their interlaced burrow network takes advantage of sandy soil. The burrows are so interconnected and the entrances so myriad that the scientists working there to decode Arctic ground squirrel mysteries carry a map denoting burrow entrance numbers so they can be certain to always return squirrels to their home burrows. Arctic ground squirrel lifestyle Why so much interest? Arctic ground squirrels are the only […]

With 2014 officially named the hottest year on record, there is evidence of the effects of rising global temperatures across the globe. The solitary, shimmering iceberg in today’s Imaggeo on Mondays photograph is a reminder that one of the best places to look for evidence of change is in glaciers. Daniela Domeisen tells the story of this lonely frozen block of ancient ice. The picture shows an iceberg on Tasman glacier lake in the Southern Alps of New Zealand, in the centre of Aoraki / […]
