From the 800s to the 1400s, about a dozen megadroughts struck the American Southwest, and all lasted longer than a decade.
It's real. It's happening. It's accelerating. And it's our fault. Human activity — particularly the production of greenhouse gasses from fossil fuel emissions — is reshaping our planet, effecting rapid environmental change at a rate never seen before. Global temperature averages are creeping upward, seas are warming, rising and becoming more acidic, and extreme weather events such as droughts, wildfires, floods and powerful storms are more commonplace. Here's where you'll find the latest on the effects of climate change, and the measures that scientists, world leaders and innovators are taking to reduce our harmful impact on the planet and mitigate the damage already done.
The global climate is changing more now than at any point in the plast 2,000 years. The Little Ice Age and the Medieval Warm Period were nothing like this.
Wildfires burning large swaths of Russia are generating so much smoke, they're visible from space, new images from NASA's Earth Observatory reveal.
"We know what's happening and what needs to be done," the haunting letter to the future reads. "Only you know if we did it."
More than 80% of California's iconic Joshua trees are likely to die at the hands of drought and fire over the next 50 years — but there's still time to save them from extinction.
Greenland's ice sheet is sliding way more than previously thought, making it more vulnerable to a warming climate, according to a new study.
Was the planet ever as hot as it is today, when every month the globe seems to be breaking one high-temperature record after another?
Trump administration officials are removing references to climate change from U.S. Geological Survey (USGS) press releases, according to a ClimateWire report.
Want to help save the world from climate change? Then grab some seeds, or some seedlings, and start planting trees like there's no tomorrow.
For the first time in recorded history, Anchorage, Alaska, reached 90 degrees F (32 degrees Celsius).
There's a huge cache of flammable ice under the ocean's surface, and it plays a key role in climate change. Scientists are only now beginning to understand what it looks like.
Summer doesn't begin for two more days, but oceanographers and climatologists are already sounding the alarm about stunning ice melts going on now in Greenland.
"Flesh-eating" bacteria that live in the ocean may be spreading to previously unaffected beach waters thanks to climate change, according to a new report.
About 60% of the world will face record-high temperatures every year for the next 100 years if we don't tackle climate change now, a new study suggests.
