Atmospheric carbon dioxide has been increasing fairly steadily for decades, but methane has accumulated at a more erratic pace. The increase virtually stalled for much of the last decade before resuming after 2007.
When weather disasters happen, is climate change to blame? The stories, video, and interactives in "Weather on Steroids" explore that question from a number of angles. It turns out that blaming climate change for wild weather's not that simple. Here’s why.
A new computer modeling study from NCAR investigates how an increase in shrubs in the Arctic may affect permafrost. Over the past few decades, a warming climate has meant that the Arctic’s grassy tundra is being increasingly overtaken by shrubs.
The effects of a warming climate on hail are largely unknown, as global climate models are too coarse in resolution to simulate hailstorms in detail. But a new modeling study now tackles this subject, looking at the future of hail in Colorado’s Rocky Mountains over the coming decades.
New research led by NCAR scientist Thomas Galarneau provides an in-depth analysis of two extreme weather events whose connection may come as a surprise: Russia’s intense heat wave in summer 2010 and the heavy rains that occurred simultaneously in Pakistan.
To honor his memory and inspire continuation of his work, about 200 people gathered in late August at NCAR for the 2011 Stephen H. Schneider Symposium in celebration of his contributions to research, education, and science communication.
Climate change is not expected to affect the extent or frequency of the El Niño/Southern Oscillation over the 21st century, but it could worsen its impacts. That’s the conclusion of a modeling study published in Journal of Climate in September.
New research that involves NCAR's Bette Otto-Bliesner questions conventional wisdom with regard to massive iceberg discharges in the North Atlantic Ocean during the last glacial period, pointing toward climate rather than ice sheet instability as a cause.
