The atmosphere is the key to life on Earth. This thin layer is what protects us from the hostile environment of space. Here you can learn all about the atmospheric sciences.
This ice-age asteroid crater isn't just the first of its kind. It may also be the smoking gun about what triggered the Younger Dryas, one of the most well-known examples of abrupt climate change.
Ice cubes usually look cloudy and opaque in the middle, despite the fact that water is clear. What's the deal?
Noctilucent clouds form at high altitudes when drifting particles become coated with ice crystals at low temperatures.
It's sometimes easy to confuse the two, but weather and climate are very different things.
The evidence is clear: Human activities — like the burning of fossil fuels — are the main driving force behind modern climate change.
The danger to the iconic statues is now greater than ever due to erosion and higher-energy wave action caused by climate change.
Red snow? Yes. It totally exists. And while it might look cool, it's not exactly what you want to see from Mother Nature.
The four seasons experienced by Earth's midlatitude regions are being gradually altered by global warming — but a climate expert says they won't completely go away.
A new model describes in more detail how the Chicxulub asteroid affected our planet, from dropping temperatures to pausing photosynthesis, with soot playing an integral part.
Very specific atmospheric conditions and just the right perspective are necessary to see the phenomenon.
Polar temperatures are changing more rapidly than equatorial ones, making the jet stream slower and wider, and extreme events longer-lasting.
Explosive solar events are bad news for Earth, so it's good to keep an eye on space weather. Newly discovered "Rossby-like" waves could help them out with that big job.
We've all seen shots of meteorologists fighting gale-force winds to report on storms. So just how high can the winds get before the reporters are knocked off their feet?
Earth's atmosphere used to be full of toxic hydrogen, but a brief period of methane smog cleared the way for valuable oxygen to set up shop.
Midwestern night owls got a meteoric surprise this week.
The atmosphere protects those of us here on land from cosmic radiation. So what about those who spend time above the clouds?
Weather bombs have produced some of the most destructive storms on record. So what is one exactly?
More than two centuries ago, the biggest volcanic explosion in human history occurred. And it had far-reaching effects.
Florida Tech filmed lightning strikes with powerful cameras that show the strikes almost 30 times slower than real life.
Once 5 miles wide, the Isle de Jean Charles has shrunk to be a spit of land barely a quarter mile wide. Soon it will no longer exist.
Just because astronauts are in space doesn't mean they can't use Twitter. These images of the Northern Lights were shot by International Space Station crewmembers.
Smartphone cameras enable us to take striking pictures of strange atmospheric phenomena—though we don’t always know what we’re seeing.
A double rainbow, man! Just the sight of one can send us babbling into happiness. And why not? Rainbows are beautiful. And two rainbows at the same time? Even better. But just how rare are these colorful arcs?
The longer ice bounces around in storm clouds, the bigger the hailstones will be when they fall to Earth. Drag that process out for a while, and comparisons to mere golf balls just won't cut it.
If the legend is true, at the end of every rainbow is a pot of gold. Does that mean if triple rainbows exist, you'll find three pots of gold?
