Atmospheric sciences help us understand and predict the weather. Learn about topics such as the seasons, why it snows, and how rainbows are formed.
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.
Most people probably think high winds are the deadliest aspect of a hurricane. But they'd be wrong. It's the wall of water brought on by storm surge that barrels on shore taking out everything in its path.
It's sometimes easy to confuse the two, but weather and climate are very different things.
Even though Hurricane Florence was downgraded to a Category 2, the storm could still unleash an historic amount of rain.
Hurricane Hector is barreling toward the erupting volcano Kilauea. What could possibly be worse?
Scorching-high temps seem to be the norm this summer. So what does this kind of heat do to your body?
Tsunamis are triggered by earthquakes and volcanic eruptions on the ocean's floor. But other massive waves are caused by wind and can come on suddenly and without warning.
The evidence is clear: Human activities — like the burning of fossil fuels — are the main driving force behind modern climate change.
The mercury soared to over 122 degrees Fahrenheit in Nawkwabash, Pakistan. It could be the highest April temp ever recorded on the planet.
Scientists across the globe attempt to forecast upcoming hurricane seasons in the Atlantic. But how — and are they right?
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.
In the mid-20th century, lightning strikes killed hundreds of Americans each year. Now, that number's dropped to only a few dozen. What's changed?
Hurricanes can range in strength from Category 1 all the way to Category 5. Learn more about hurricane categories in this HowStuffWorks Illustrated video.
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.
Researchers studying tornadoes use a common theory of economics to determine casualty rates.
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.
