Tides may regularly swamp many U.S. cities
As sea levels rise, many cities will begin to experience frequent and extensive flooding at high tides. In some areas — even Washington, D.C. — such flooding could become a weekly headache.

Thunderstorms can generate powerful radiation
Thunderstorms don’t just hurl lightning bolts. Some churn out high-energy radiation that can be seen by spacecraft. This radiation offers scientists a glimpse of the inner workings of thunderclouds.

Tar pit clues provide ice age news
New analyses of insects and mammals trapped in the La Brea Tar Pits point to climate surprises during the last ice age.

Climate change brings new neighborhood birds
Climate change has made winters a little bit warmer. Many bird species are now wintering a lot farther north than they did a few decades ago, a new study finds.

The worst drought in 1,000 years
The 1934 drought, during a period in American history known as the Dust Bowl, was the worst in a millennium, a new study finds. While the drought had natural origins, human activities made it worse.

Lightning strikes will surge with climate change
Warming temperatures will lead to 50 percent more lightning strikes across the 48 U.S. states in the next century, researchers report. That increase could lead to more warming, more fires and even more deaths.

Explainer: Understanding ice ages
Earth slowly wobbles, tilts and stretches (or contracts) as it orbits the sun. These changes may be fairly small and subtle. Still, their cumulative impacts can be huge — sometimes triggering the slow onset of an ice age or an abrupt thaw.
