Extreme Tornado Outbreaks Are Becoming More Extreme

Extreme Tornado Outbreaks Are Becoming More Extreme

Outbreaks of tornadoes — where multiple tornadoes form over an area in just a few hours or days — are responsible for most of the devastating destruction caused by severe weather, and a new analysis has reached a worrying conclusion about the worst of these outbreaks.

What a Warmer Future Means for Southeastern Wildfires

What a Warmer Future Means for Southeastern Wildfires

When Jeff Prestemon stepped outside his home near Raleigh, N.C., last Friday around 9 a.m., the skies were clear, the air “perfectly breathable.” But just an hour-and-a-half later, the winds had shifted, drawing with them the smoke from regional wildfires. “It was putrid,” Prestemon, a research forester with the U.S. Forest Service, said. “It stung… Read More

The Arctic is a Seriously Weird Place Right Now

The Arctic is a Seriously Weird Place Right Now

The sun set on the North Pole more than a month ago, not to rise again until spring. Usually that serves as a cue for sea ice to spread its frozen tentacles across the Arctic Ocean. But in the depths of the polar night, a strange thing started to happen in mid-October. Sea ice growth slowed to a crawl and even started shrinking for a bit. Intense … Read More

U.S. Record Highs Will Far Outpace Lows With Warming

U.S. Record Highs Will Far Outpace Lows With Warming

Over the first decade of this century, record high daily temperatures in the U.S. were registered twice as often as record lows, a clear sign of global warming. If emissions of heat-trapping greenhouse gases continue on their current track, that ratio could become even more skewed, potentially reaching 15-to-1 by midcentury, a new study finds. The… Read More

2016 is set to be the hottest year on record by a significant margin, with temperatures that are 2.2˚F (1.2˚C) above pre-industrial times, the World Meteorological Organization told diplomats gathered in Marrakech, Morocco, to discuss international action to limit global warming to less than 2˚C by the end of the century. “Another year. Another… Read More

Rio’s Beaches Take Battering From Storm Surge

Rio’s Beaches Take Battering From Storm Surge

Scientists in Rio de Janeiro have warned that the city’s sea defenses may not be able to cope with the effects of climate change after a record storm surge swamped beaches, dumping hundreds of tonnes of sand across nearby roads and buildings. Waves of almost four metres in the weekend storm left beach flags fluttering in tatters, forced the … Read More

Warm Temps Slow Arctic Sea Ice Growth to a Crawl

Warm Temps Slow Arctic Sea Ice Growth to a Crawl

A strange thing is happening in the Arctic. After dipping to its second-lowest extent on record in September, sea ice has struggled mightily to rebound in October. Freakishly mild weather coupled with a warmer than normal ocean are in large part responsible for the great sea ice slowdown of 2016. It’s just the latest piece of evidence that 2016 is … Read More
