Earth just had its first storm-free hurricane peak in 38 years

This year marks the first time since 1977 that September 12, the typical height of the Atlantic hurricane season, passed without a single major cyclone anywhere in the Northern Hemisphere.

Burning remaining fossil fuels would eradicate Antarctic ice

Finishing off Earth’s available carbon resources would nearly eliminate the Antarctic ice sheet and raise sea levels by more than 50 meters, new research calculates.

Virtual twister reveals possible source of tornado longevity

First computer simulation of a long-lived EF5 tornado may reveal why some twisters stick around.

Hurricane’s tiny earthquakes could help forecasters

Hurricane Sandy set off small earthquakes under its eye as it moved up the U.S. East Coast in 2012. The tiny tremors could help researchers track the behavior of future storms, researchers propose.

Katrina’s legacy: Refining hurricane forecasting

Ten years following Hurricane Katrina’s formation, the storm’s devastating legacy in New Orleans and beyond continues to drive storm forecast improvements.

Carbon cuts could save U.S. farmers billions of dollars

Reducing carbon emissions could save U.S. agriculture industry billions of dollars annually by curtailing droughts.

Iceless Arctic summers now expected by 2050s

The Arctic Ocean will have its first ice-free summer in the 2050s, nine years earlier than previously forecast, according to improved simulations.

Desert dig uncovers caches of missing CO₂

Irrigation water may wash significant amounts of carbon into groundwater systems beneath Earth’s deserts, researchers propose.

Neuroscience

Global warming unpaused, how space affects the brain and more reader feedback

A reader shares a story about Stephen Jay Gould, while others discuss how to protect the brain from radiation in space and whether 2014 was the hottest year on record.

Paleontology

Sudden heat spikes did in Ice Age’s mammoth mammals

Abrupt warming and excessive hunting by ancient humans were responsible for the disappearance of many large mammals, including woolly mammoths, during Earth’s last glacial period.

Sea level rise threatens sea turtles

Sea level rise is causing coastal areas to be inundated with water. Even short periods of being wet can kill sea turtle eggs, a new study finds.

Climate

Carbon dating may soon lead to mismatches

Carbon released from burning fossil fuels will jeopardize the effectiveness of many carbon dating applications, new research predicts.
