Extreme Storms to Multiply, Intensify Across U.S., New Simulations Suggest

By Tim Radford

For the U.S., harder rain is on the way: America's summer thunderstorms are about to get stormier. Later this century, the notorious mesoscale convective storms of middle America will not just darken skies—they will also dump as much as 80 percent more water on the farms, highways and cities of the 48 contiguous states.

Mesoscale thunderstorms cover an area of around 100 kilometers (approximately 62 miles): these have been on the increase, both in frequency and intensity, in the last 35 years and new research suggests that, as the world warms, their frequency could triple.

Why Remote Antarctica Is So Important in a Warming World

By Chris Fogwill, Chris Turney and Zoe Robinson

Ever since the ancient Greeks speculated a continent must exist in the south polar regions to balance those in the north, Antarctica has been popularly described as remote and extreme. Over the past two centuries, these factors have combined to create, in the human psyche, an almost mythical land—an idea reinforced by tales of heroism and adventure from the Edwardian golden age of "heroic exploration" and pioneers such as Robert Falcon Scott, Roald Amundsen and Ernest Shackleton.

Recent research, however, is casting new light on the importance of the southernmost continent, overturning centuries of misunderstanding and highlighting the role of Antarctica in how our planet works and the role it may play in a future, warmer world.

Record Number of Americans 'Very Worried' About Climate Change

As someone who writes about the environment on a near-daily basis, the fact that a large chunk of Americans (about one in eight) reject the near scientific consensus of climate change can be a tough pill to swallow.

But after a year of record-breaking heatwaves, massive wildfires in the west, and a string of destructive hurricanes, it appears that my fellow U.S. citizens are waking up to the realities of our hot, new world, according to the latest nationally representative survey from the Yale Program on Climate Change Communication and the George Mason University Center for Climate Change Communication.

More Harvey-Sized Hurricanes Likely to Hit Texas

By Tim Radford

The probability that some city in the U.S. state of Texas will be hit again by Harvey-sized hurricanes, rainstorms that will dump half a meter of water in a short space of time, has increased sixfold in this century and will have increased 18-fold by 2100, thanks to climate change driven by global warming.

In the late summer of 2017, Hurricane Harvey dropped 65 cms of water on the city of Houston in Texas. It was the start of the largest natural disaster in the U.S. since Hurricane Katrina pounded New Orleans in 2005. Harvey claimed an estimated 70 lives, and created more than $150 billion in damage.
