The Northeast U.S. has been taking the brunt of rising sea levels not just in the country but in the world, with waters rising three to four times faster than the global average, according to new data. But that doesn't spare the West Coast; in a decade, rising sea levels could flood the San Francisco International Airport.
When we think of rising sea levels, we think of global climate change and melting ice caps. Yet there's a disparity in the raw data. During the second half of the last century, global sea levels rose 1.8 millimeters per year, according to tide gauges. But it's been determined that melting ice caps and glaciers have only contributed to 1.1 millimeters per year of that. So where did the other 0.7 millimeters come from? A new study has a remarkably simple answer: from you.
A storm system brewing in the Rockies today might trigger an outbreak of deadly tornadoes in the nation's midsection on Friday, according to meteorologists. In case you missed it, read PopSci senior editor Seth Fletcher's piece about how tornadoes form — and how climate change may be making them worse.
Changes on the planet are affecting the world's tallest mountain, casting doubt on its climbability and even its height. Sherpas are wondering whether warmer climates will render Mount Everest too dangerous to summit, and geologic changes in the Himalayas have raised uncertainties about its altitude, according to separate reports.
Back in the day of the first mammals, horses started out the size of house cats, weighing about 8 pounds and standing only a few inches tall. Then they got even littler, a direct result of the warm temperatures that characterized the Eocene era. Only when Earth cooled down a bit did the beasts get big, according to a new study — the first evidence that temperature directly affects body size. Interesting results when you think about rising global temperatures. Are Earth’s animals about to undergo a New Shrinkening?
Earth’s clouds are sinking lower in the sky, with fewer clouds at high altitudes and lower cloudtops in general, says a new analysis of satellite data. The coming fog means that Earth will cool down more efficiently — so the lowering of clouds could slow the effects of global warming.
Police in Capitán Prat Province, Chile, have stopped a refrigerated truck carrying nearly 6 tons of ice bound for cocktail bars in Santiago, and arrested the driver on suspicion of having thieved the ice from a glacier in a Patagonian national park.
The tornado that destroyed my hometown was born in an otherwise unremarkable atmospheric collision over the American Central Plains. On May 22, 2011, a geostationary satellite 22,300 miles overhead recorded a large collection of cloud lines drifting over southeastern Kansas. At around 2 p.m, one of the cloud lines exploded, like a cartographic-scale dry-ice bomb.
