How Hot Your City Could Be By 2100 If Climate Change Goes Unchecked

It's a sorry truth that hits you mid-July: Average summer temperatures have been rising since the 1970s. If we continue down this path, according to a new study by Climate Central, in 2100, summers in Boston will feel more like sticky Miami—and summers in Miami will feel like toasty Harlingen, Texas. » 7/09/14 6:00pm Yesterday 6:00pm

A Tantalizingly Brief Glimpse Inside Fabien Cousteau's Underwater Lab

Fabien Cousteau just concluded his 31-day underwater research mission, where six scientists studied coral reefs in a small chamber 63 feet underwater off the coast of Key Largo. The long-term underwater residence gave them a firsthand glimpse of some never-before-seen underwater phenomena, as Cousteau told PBS's… » 7/06/14 10:00am Sunday 10:00am

Sea Level Rise Is Forcing This Island Nation To Buy Land 1200 Miles Away

The nation of Kiribati is a string of 30 or so tiny islands in the Pacific, each just a few feet above the sea. Thanks to climate change and rising seas, it's officially screwed. So Kiribati's government has come up with a drastic and unprecedented decision: buy 5,460 acres of land that is 1,200 miles away in a whole… » 7/03/14 11:02am 7/03/14 11:02am

Melting Arctic Ice Is Drastically Changing National Geographic's Atlas

When the the 10th edition of the National Geographic world atlas is released this fall, it will look markedly different from previous versions. That field of endless white usually covering the very north of the planet will be dramatically reduced to reflect the real-life shrinkage of the Arctic ice sheet. » 6/10/14 1:00pm 6/10/14 1:00pm

First-person point of view video recorded by a wild polar bear

US Geological Survey's biologists attached cameras and radio collars to four free-ranging female Alaskan polar bears last April. One of the resulting videos shows one of the bears in action in the Beaufort Sea, checking out a potential mate, swimming below ice, and trying to eat a frozen seal (which is kind of gross.) » 6/08/14 5:04pm 6/08/14 5:04pm

How Obama's Power Plant Regulations Will Transform Our Electric Grid

President Obama and the EPA have just taken their biggest and boldest step ever to fight climate change. The Clean Power Plan, unveiled by the EPA today, is far more important than the Keystone XL pipeline—if also far less sexy to slap on a poster. But these carbon-cutting regulations have the potential to transform… » 6/02/14 3:12pm 6/02/14 3:12pm

Neil deGrasse Tyson explains weather and climate change for dummies

Weather and climate change are not the same. While weather is unpredictable from one week to the next, climate follows a stable pattern that is developed over centuries. Neil deGrasse Tyson explains these seemingly obvious differences so even the dumbest people can understand them. » 5/30/14 4:20pm 5/30/14 4:20pm

The Antarctic Ice Sheet Has Started to Collapse and Nothing Can Stop It

For decades, scientists have feared the collapse of the West Antarctic ice sheet—a vast swath of ice that could unleash a slow but unstoppable 10-foot rise in sea levels if it melted. So here is today's terrible news: we now know the ice sheet is melting. And there's pretty much nothing we can do about it. » 5/12/14 2:00pm 5/12/14 2:00pm

NASA's New Orbiter Will Watch Plants Photosynthesize from Space

For the last 25 years, scientists have been able to monitor the "greenness" of trees from space and use that as a tool for evaluating plant health. The problem is that greenness isn't a good indicator for stresses—such as drought—because some trees (think pines) continue to be a lovely green until they're dead.… » 5/06/14 9:23am 5/06/14 9:23am

This Huge Nuclear Waste Dump Will Be Washed Away By Rising Sea Levels

A dumping ground for nuclear waste located near the British coast is "virtually certain" to be washed away by rising sea levels, a new report warns. The UK Environment Agency has admitted that constructing the Drigg Low-Level Waste Repository so near the coast was a mistake, and that one million cubic meters of… » 4/21/14 9:41am 4/21/14 9:41am

How We Could Save the World From Global Warming Before Our Time Is Up

We've blown our chances of fully counteracting the effects of climate change; recently-released reports from the International Energy Agency and the UN Environment Programme (UNEP) provide plenty of evidence. But all hope is not yet lost, we've still got a small chance to keep from irreversibly poisoning our… » 4/16/14 11:00am 4/16/14 11:00am

4 Ways Tiny Microbes Changed Life on Earth Forever

This is the microbes' world—we just live in it. Throughout the history of Earth, microbes have radically reshaped life on the planet, from creating the very air we breath to wiping out almost all life on Earth. Don't underestimate the power of tiny, tiny microbes populating the Earth trillions of times over. » 4/07/14 12:00pm 4/07/14 12:00pm

There's No End in Sight for California's Megadrought

California's chief snow surveyor ventured into the Sierras this week to see how much water the state can expect from the spring melt—and he came back with very bad news. The devastating drought that the state's been dealing with the past few months will continue to devastate for the foreseeable future. » 4/03/14 3:20pm 4/03/14 3:20pm
