Since the 1970s, it has been suggested that kangaroos don’t fart — or rather, the (ahem!) gas they emit contains very little, if any, methane. But now, new research suggests this isn’t true.
05 November 2015, 07:05 AM ET
Methane gas fermented in the guts of farm animals contribute up to 26 percent of U.S. methane emissions.

The king crab could soon take over a whole new kingdom, and it has global warming to thank for the conquest.
29 September 2015, 04:02 PM ET
For tens of millions of years the Bathyal King Crabs have steered clear of the freezing Antarctic waters. Today, with waters around the frozen continent warmer than ever previously recorded...

California's drought is not only fueling more frequent and voracious wildfires, but also making it more difficult for firefighters to get the water they need to douse flames, experts say.
24 September 2015, 01:31 PM ET
The snowpack in California's Sierra Nevada mountains is the lowest in centuries, which isn't good news for the drought in the region now or in the future.
24 September 2015, 10:54 AM ET

Idle electronics, the energy vampires in nearly every U.S. home, aren't going away — but you can take steps to pull the plug, and save some money.
17 September 2015, 04:23 PM ET
If human-caused climate change continues unabated our world could change dramatically. A new visualization was created by the National Center for Atmospheric Research that shows the ice loss if current temperature trends continue.
15 September 2015, 04:12 PM ET
A dramatic photograph of a starving polar bear went viral online, but scientists say it's a stretch to definitively link polar-bear starvation to climate change.

Burning all the fossil fuels on Earth would trigger enough global warming to completely melt the Antarctic ice sheet, raising sea levels by 200 feet (60 meters), and drowning major cities that are home to more than a billion people, the researchers said.
08 September 2015, 04:14 PM ET
Unseasonable heat has much of the U.S. in its grip. Global warming will likely make heat waves more intense.
02 September 2015, 02:48 PM ET
A new global census of all the trees on Earth estimates that more than 3 trillion call this "pale blue dot" home. But the total number of trees on the planet has dropped by almost 50 percent since human civilization began.
