Heat contained in the Earth's crust acts like a life-jacket, and without it much of North America would be under water, suggests research at the University of Utah.
The flooding predicted because of global warming is a much more immediate threat, the researchers note. It would take billions of years for North American rock to cool to the point where it will become denser and sink enough to put much of the continent under water.
The research suggests for the first time that about half the elevation of any place in North America is related to temperature differences within the Earth's crust, with most of the rest due to differences in what the rocks are made of.

Torrential storms flooded parts of central Texas early Wednesday, stranding people on roofs, in trees and in vehicles, and the weather was so treacherous that some helicopter rescue attempts had to be abandoned.
Blistering hot weather caused the death of ten people in two days across Italy, as abnormal temperatures set in Tuesday, local media said Wednesday.
Media reported that elderly people suffering from heart problems were most affected by the unbearably hot weather, while about half a million residents at Apennines were left without electricity, disrupted due to the mass surge by consumers switching on fans and air conditioners.
A local resident of Sicilia said forests were on fire in the south of the country while temperatures over the last two days exceeded 42 °C (108 °F) in Palermo, and over 46 °C (115 °F) in Catania.

Johannesburg recorded its first confirmed snowfall for almost 26 years overnight as temperatures dropped below freezing in South Africa's largest city, grounding flights at its main airport.
The heaviest falls were over the southern suburb of The Hill, where four inches of snow fell, said Venetia Magane, a forecaster at the South African Weather Service in Pretoria. Temperatures in the city fell to minus 1 degree Celsius (30.2 degrees Fahrenheit) during the night, she added.

An island off the coast of Higashihiroshima is crumbling away due to countless crustaceans that have made holes in its rocks and caused its highest peak to completely disappear.
The rocky Hoboro Island has become a breeding ground for huge numbers of creatures known in Japanese as nanatsuba-kotsubumushi, a type of isopod. The surging number of insects has caught the attention of local researchers.
"It's rare, even on a global scale, to hear of biological erosion that has proceeded on such a large scale and at such a rapid pace as to alter the landscape of an island," said Yuji Okimura, an emeritus professor at Hiroshima University.

Heavy rainstorms along with lightning and hail since last week have hit many parts of China, killing nearly 50 people, destroying farmland and sweeping away houses.
On Monday afternoon, lightning killed five people building a tomb in Zhejiang. Altogether 48 people have died and 12 are missing after a week of heavy rains and thunderstorms that swept up the Yangtze River valley and across southern China.

A moderate earthquake shook the Northern California coast up to the Oregon border Sunday night, but there were no reports of injuries or damage.
The magnitude 5.1 earthquake struck along the Pacific Ocean floor at 7:32 p.m. about 41 miles northwest of Eureka, according to the U.S. Geological Survey.

The state climatologist says Georgia is in for some scorching days in July and August unless the state gets some rainfall.
Climatologist David Stooksbury said yesterday that 9 more counties are in "extreme drought;" upping the total to 104 counties.
There's little hope that the drought will be snapped without tropical storms in July and August.

With parts of California emerging from one of the driest winters in more than a century, the fire devouring Lake Tahoe's south shore might be a harbinger of what's in store for the western United States during the long, hot summer ahead, experts warned Tuesday.
Rainfall in Southern California has dwindled to near record lows this year, while the little moisture Northern California received already is giving way to dry forests and brittle, golden grasses.
