With Keystone In Limbo, Alberta Launches Carbon Contest
Best known as the home to Canada's oil sands and Keystone pipeline, Alberta is calling for climate change solutions.… Read More
Nearing a Tipping Point on Melting Permafrost?
Nearly a quarter of the Northern Hemisphere’s land surface is covered in permanently frozen soil, or permafrost, which is filled with carbon-rich plant debris — enough to double the amount of heat-trapping carbon in the atmosphere if the permafrost all melted and the organic matter decomposed. According to a paper published Thursday in Science, … Read More
Volcanic CO2 Caused Ancient Episodes of Global Warming
In order to predict our climate future, scientists spend a lot of time looking into the past, trying to understand what conditions were like during times when the planet was much warmer or much cooler than it is today. The latest instance: a report published in the February issue of the journal Geosphere, offering a plausible explanation for swings… Read More
Ex-IPCC Head: Prepare for 5°C Warmer World
The world has missed the chance to keep greenhouse gas emissions below the level needed to prevent the temperature climbing above 2° Celsius, according to the British scientist who used to chair the IPCC, the Intergovernmental Panel on Climate Change.… Read More
Thinning Ice Is Turning Arctic into an Algae Hotspot
Shrinking, thinning Arctic sea ice appears to be accelerating the growth of algae in polar waters, a new study finds, a development that could alter the region’s ability to absorb carbon from the atmosphere. Scientists cruising central Arctic waters last summer aboard the research ship Polarstern were stunned to discover dense, shaggy deposits of… Read More
NASA to Launch New Earth-Observing Satellite
If the weather holds, NASA will launch its newest Earth-observing satellite from Vandenberg Air Force Base in southern California late Monday morning. An Atlas V rocket is scheduled to carry Landsat 8 into space just after 11 a.m. Pacific time. Once in orbit, the $855 million probe will begin capturing detailed images of Earth’s surface, adding to… Read More
Climate Change Set to Batter U.S. Agriculture, Forests
Climate change is likely to transform U.S. agriculture by mid-century, reducing yields of many staple crops and the productivity of livestock operations, according to a new government analysis. Rising temperatures and shifting precipitation patterns will also harm the nation’s forests, increasing their vulnerability to fires, insect infestations … Read More
Study Downplays Risk of Catastrophic Amazon ‘Dieback’
In a warming world, tropical forests may be hardier than previously thought. For scientists who study the Amazon, the worst-case scenario has long been clear. As the planet warms, some models suggest, the rainforest will dry and die, sending a massive shot of carbon into the atmosphere to further warm the planet. … Read More
