A multisatellite observing system that was only a gleam in researchers’ eyes in the 1990s is now a key tool for monitoring Earth’s atmosphere. An ambitious follow-up project could yield up to ten times the data gathered by the current satellites.

The atmosphere has dealt Houston more than a few wild cards over the last few years, including two devastating tropical cyclones and unprecedented drought. While dealing with such weather threats, the nation's fourth largest city is also taking steps to tackle longer-term climate change.

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.

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.

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?

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.
