Why would a cooling of the Pacific Ocean help stoke tornadoes in the United States? Researchers are beginning to dig deeper into the connections between severe U.S. thunderstorms and the sea.

Days lengthen as spring arrives, but several other signs of the season are showing up earlier and earlier. Some animals and insects aren’t adapting fast enough to this "asynchrony," and there's an increasing disconnect with legal dates that govern hunting and other resource management.

The winter of 2011–12 was the second in a row to feature La Niña, the quasi-cyclic cooling of the eastern tropical Pacific—but the two seasons departed from the La Niña script in strikingly different ways.

A new study finds that extremely warm summers are not only occurring more frequently in the contiguous United States, but are likely to become normal by mid-century.

A new study that provides the first comprehensive satellite analysis of Earth’s melting glaciers and ice caps has grave implications for sea level rise.

The growing array of tools at the disposal of climate scientists doesn’t necessarily make life any easier for them. Each set of data has its idiosyncrasies, some of which aren’t evident at first glance.

Not all kinds of extreme weather have the same relationship with our atmosphere's increasing burden of greenhouse gas. Here's a summary of what scientists already know and what they're working to nail down.

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.

There's insurance, and then there's reinsurance - and both are affected by weather and climate. So how are insurers planning for a future where the impact of weather catastrophes meets climate change?

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.

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.
