How to Understand These Gorgeous Satellite Data Maps of the Earth

NASA's Earth Observatory has spent over fifteen years using satellites to collect hordes of real-time data across our planet's surface. They reveal everything from temperature and energy use, to how much radiation we beam into space. Here's how to understand satellite data maps to understand our planet's vital signs. » 2/26/15 11:39am 2/26/15 11:39am

Massive Forest Fires Could Be Cooling the Earth

Wait, what? A forest fire may not sound like a great way to cool off, but Earth's climate is a complicated beast. It turns out that some of the world's fiercest blazes are actually lowering our planet's temperatures. » 2/16/15 3:45pm 2/16/15 3:45pm

Scientists Weigh in on Plans to Hack the Weather and Cool the Earth

Geoengineering, i.e. tinkering with the climate to stop the rising tides of climate change, is a provocative and frankly still kinda crazy idea. Two long-awaited reports from the National Academy of Sciences (NAS) out today have some pretty harsh words about geoengineering. » 2/10/15 4:10pm 2/10/15 4:10pm

U.S. Senate Agrees Climate Change Is Real, 98 Votes to 1

The U.S. Senate has voted overwhelmingly in agreement that climate change is real, with a staggering 98 votes to 1. All that remains is for them to agree on the cause. » 1/22/15 4:15am 1/22/15 4:15am

Here's a Shocking Visualization of the Planet's Rising Temperatures

Last week, NASA and NOAA announced that 2014 was the hottest year in Earth's recorded history. This animation by Bloomberg brings that finding into sharp focus. » 1/20/15 6:04am 1/20/15 6:04am

2014 Was the Hottest Year in Earth's Recorded History 

It's official: 2014 is the hottest year since we humans started recording temperatures on Earth, according to two independent analyses by NASA and NOAA. Last year's global temperatures broke record a record set in 2010 and, before that, in 2005. We are on a steady march toward a warmer Earth. » 1/16/15 12:30pm 1/16/15 12:30pm

You Can Trace a Typhoon Through Changes in Ocean Life

You're looking at a selection of marine life, from shrimp to jellies. But what's special abou these little blighters is that they reveal the presence of a typhoon in their past. » 1/13/15 5:57am 1/13/15 5:57am

The coldest ground-level temp ever recorded on Earth was -128.6 degrees…

It looks like winter has already arrived for much of the U.S. But you can feel a bit better by putting things in perspective. At least it's not -128.6 degrees Fahrenheit. That's the coldest temperature ever recorded by humans at ground level on this planet. » 11/26/14 5:44pm 11/26/14 5:44pm

Climate Change Could Mean We See a Lot More Lightning Strikes 

Add lightning to the list of dangers climate change will likely magnify. A new study projects that a warmer climate could mean 50 percent more lightning strikes in the U.S. in the coming decades. » 11/13/14 4:33pm 11/13/14 4:33pm

Don't Panic: The Ozone Hole's Holding Steady

Despite research suggesting that the ozone layer is still being chewed apart, NASA's most recent study of the Antarctic ozone hole reveals it isn't getting any larger. » 10/31/14 5:15am 10/31/14 5:15am

The Southwest Has a Methane Hotspot as Big as Delaware

NASA and the University of Michigan have discovered a hotspot which contributes the largest concentration of the greenhouse gas methane in the entire country. And it's 2,500 square miles in size. » 10/10/14 6:00am 10/10/14 6:00am

Earth Has Been Getting Warmer Way Faster Than We Thought

We know that the planet is getting warmer—but it turns out that it's happening faster than we thought. Turns out scientists have been underestimating warming increases because of inaccurate temperature recordings taken in the southern oceans. » 10/06/14 8:00am 10/06/14 8:00am

Atmospheric CO2 Increases Have Hit a 30-Year High

Don't panic (you should panic) but the rate at which the levels of CO2 in the atmosphere are rising just hit a 30-year high—and if rates don't slow, then we'll soon breach the levels that experts claim are safe. » 9/09/14 9:32am 9/09/14 9:32am

There Are Huge Plumes of Methane Leaking From the Atlantic Floor

Methane can come from all kinds of places. But now a team of researchers has discovered over 500 bubbling methane vents just off the east coast of the U.S. that are releasing the gas, too, » 8/25/14 7:50am 8/25/14 7:50am

The Earth's Ozone Layer Is Still Being Chewed Apart

If you thought that the depletion of the ozone layer was a problems of the 90s, think again: according to new NASA research, the Earth's atmosphere contains an unexpectedly large amount of ozone-depleting chemical, decades after it was banned worldwide. » 8/21/14 4:20am 8/21/14 4:20am

When a Climate Scientist Publicly States "We're F**ked" Things Are Bad

It's one thing to note the unusually hot weather we've been having and then slather on some suncream. But when a climate expert unceremoniously concedes that the planet is "f**ked", it's probably time to get seriously worried. » 8/06/14 8:00am 8/06/14 8:00am

Even a Small Nuclear Showdown Would Mean Worldwide Disaster

In these decades after the Cold War, "nuclear winter" is an idea that can feel as remote as science fiction. But using state-of-the-art climate models, scientist have calculated exactly what nuclear winter will look like after even a small, regional conflict. Boy is it bad. » 7/21/14 7:30pm 7/21/14 7:30pm

How Quantum Mechanics Explains Global Warming

We all know that carbon dioxide is contributing to the warming of our planet but... how, exactly? In this video, Lieven Scheire explains how quantum mechanics holds the answer. » 7/18/14 5:51am 7/18/14 5:51am

Why Tall Buildings Make Cities Hotter

The breezy dark corridors between a city's tallest buildings seem like shady respites from the blistering summer sun. But it turns out those shadowy urban canyons are actually making your city more hell-like. NASA released some images today shot from the International Space Station which help to illustrate why. » 6/09/14 5:20pm 6/09/14 5:20pm
