Tim Radford – Arctic Warming Gives U.S. and Europe the Chills

LONDON—Warming in the Arctic—one of the fastest-warming regions on the planet—could be heightening the chances of extreme winters in Europe and the US.

As the Arctic warms, the stratospheric jet stream that brings occasionally catastrophic ice storms and record snow falls to the eastern United States could also be on the move, according to new research in the journal Nature Climate Change.

The phenomenon is a natural one. Some years the track of the jet stream ...

Indiana University researchers find Earth may be home to 1 trillion species

BLOOMINGTON, Ind. — Earth could contain nearly 1 trillion species, with only one-thousandth of 1 percent now identified, according to a study from biologists at Indiana University.

The estimate, based on the intersection of large datasets and universal scaling laws, appears today in the Proceedings of the National Academy of Sciences. The study’s authors are Jay T. Lennon, associate ...

Not ‘If’ But ‘How’: New Study Shows Why All Extreme Weather Is Climate Related – Nadia Prupis

The debate over climate change has long focused on determining attribution—whether rising greenhouse gases and global warming caused a particular storm, drought, flood, or blizzard. Now, a new study inNature Climate Change published Monday seeks to shift the underlying question from “if” to “how.”

“The climate is changing,” wrote National Center for Atmospheric Research scientists Kevin Trenberth and John Fasullo and University of Reading physicist Theodore Shepherd in their study, Attribution of ...

Exposure of US population to extreme heat could quadruple by mid-century

U.S. residents’ exposure to extreme heat could increase four- to six-fold by mid-century, due to both a warming climate and a population that’s growing especially fast in the hottest regions of the country, according to new research.

The study, by researchers at the National Center for Atmospheric Research (NCAR) and the City University of New York (CUNY), highlights the importance of considering societal changes when trying to determine future climate impacts.

“Both population change and climate change matter,” said NCAR scientist Brian ...

Plants may not protect us against climate change – Tim Wogan

Plants are one of the last bulwarks against climate change. They feed on carbon dioxide, growing faster and absorbing more of the greenhouse gas as humans produce it. But a new study finds that limited nutrients may keep plants from growing as fast as scientists thought, leading to more global warming than some climate models had predicted by 2100.

Plants need different nutrients to thrive, such as nitrogen for making the light-absorbing pigment chlorophyll and phosphorus for building proteins. Farmers supply ...

How Long Can Oceans Continue To Absorb Earth’s Excess Heat?

For decades, the earth’s oceans have soaked up more than nine-tenths of the atmosphere’s excess heat trapped by greenhouse gas emissions. By stowing that extra energy in their depths, oceans have spared the planet from feeling the full effects of humanity’s carbon overindulgence.

But as those gases build in the air, an energy overload is rising below the waves. A raft of recent research finds that the ocean has been heating faster ...
