Pruning the Mississippi River Could Protect New Orleans From the Next Katrina

When Hurricane Katrina devastated New Orleans a decade ago, its destructive power was unprecedented. But these days, extreme weather events are becoming eerily common.

If Humans Never Existed, the World Would Have More Mammals

There aren’t many large mammals around anymore in, most of the world. That’s mostly because one mammal species — Homo sapiens — has taken a heavy toll on its competition.

This Is What the Ocean Might Look Like in 100 Years

The volcanic island of Maug is really three volcanic peaks, rising up from a remote part of the Pacific Ocean. Underwater vents on the side of Maug’s caldera seep carbon dioxide into the ocean. The shallow water around the volcano is full of coral reefs — except near the underwater vents, where researchers have… » 8/11/15 12:00am 8/11/15 12:00am

A Warm Ocean "Blob" In the Pacific Is Feeding a Toxic Algae Bloom 

The Blob has been there for over a year—a cauldron of extra-warm ocean temperatures off the coast of the Pacific Northwest that just won’t budge. The Blob has already affected food availability and habitats for marine life, and now scientists are starting to see at least one dangerous side-effect of the Blob: A… » 8/07/15 8:00pm 8/07/15 8:00pm

Help CA Gov. Jerry Brown Deliver Climate Change Memo To GOP Candidates

The climate is changing and no state has felt this more acutely than drought-plagued California, where 100,000 acres of forest are burning today—including one fire that’s 100 square miles. Today, the state’s governor Jerry Brown asked for help posing a question to Republican leaders: “What is your plan to deal with… » 8/05/15 2:45pm 8/05/15 2:45pm

Four Technologies That Could Let Humans Survive Environmental Disaster

Scientists say we blew it. We bought too many plastic trinkets from Walmart; we drove too many gas-guzzling Broncos. We made babies like rabbits without questioning if the planet could handle so many people. Well, it looks like it couldn’t. Climate change is here to stay, and it’ll probably end up affecting nearly… » 8/04/15 10:50am 8/04/15 10:50am

Climate Change Doomed the Mammoths

Humans are pretty good at mucking up the Earth, whether we’re warming the climate, leveling the rainforest, or driving wild animals extinct. But climate change, at least, was wreaking havoc long before we got involved. For instance, it’s looking very likely that global warming, rather than human spears, doomed Earth’s… » 7/24/15 4:40pm 7/24/15 4:40pm

Remember When 2014 Was the Hottest Year On Record? Now 2015 Is.

Doesn’t it seem like only last week scientists confirmed that 2014 was indeed the hottest year on record? Well, you don’t have to worry about that anymore because scientists have now determined that the first half of 2015 has managed to break all those records—and 2015 will now likely be the hottest year recorded on… » 7/20/15 7:00pm 7/20/15 7:00pm
