New research explains why Hurricane Harvey intensified immediately before landfall

A new study explains the mechanism behind Hurricane Harvey’s unusual intensification off the Texas coast and how the finding could improve future hurricane forecasting.

Cracks herald the calving of a large iceberg from Petermann Glacier

Cracks in the floating ice tongue of Petermann Glacier in the far northwest reaches of Greenland indicate the pending loss of another large iceberg. Glaciologists from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) in Bremerhaven, Germany report in a new study that the glacier’s flow rate has increased by an average of 10 percent since the calving event in 2012, during which time new cracks have also formed – a quite natural process.

Climate change may push Santa Ana fire season into winter months

Climate models predict a narrowing of the Santa Ana season in tandem with the wet season in Southern California over the next century, which could leave vegetation dry and fire-prone as winds peak in December and January, according to a new study.

Climate change could make corals go it alone

Climate change is bad news for coral reefs around the world, with high ocean temperatures causing widespread bleaching events that weaken and kill corals. However, new research finds corals with a solitary streak – preferring to live alone instead of in reef communities – could fare better than their group-dwelling relatives.

Two- to three- fold increase in heatwave occurrence and severity seen directly in UK temperature records

A two- to three-fold increase in heatwave activity in the United Kingdom since the late 19th century has been identified in a new analysis of historical daily temperature data.

New research shows significant decline of glaciers in Western North America

The first comprehensive assessment of glacier mass loss for all regions in western North America (excluding Alaskan glaciers) suggests that ice masses throughout western North America are in significant decline: glaciers have been losing mass during the first two decades of the 21st century.

Leafcutter ant colonies may be an overlooked source of carbon dioxide emissions, new study finds

Factories mass produce goods for society and many emit greenhouse gases in the process, but not all are run by humans. Some factories lie underground and are operated around the clock by tireless six-legged workers. A new study in the Journal of Geophysical Research: Biogeosciences, a journal of the American Geophysical Union, shows leafcutter ant nests can emit carbon dioxide at a rate thousands of times higher than regular soil.

Wintertime Arctic Sea Ice Growth Slows Long-term Decline: NASA

New NASA research has found that increases in the rate at which Arctic sea ice grows in the winter may have partially slowed down the decline of the Arctic sea ice cover. As temperatures in the Arctic have warmed at double the pace of the rest of the planet, the expanse of frozen seawater that blankets the Arctic Ocean and neighboring seas has shrunk and thinned over the past three decades. The end-of-summer Arctic sea ice extent has almost halved since the early 1980s. A recent NASA study found that since 1958, the Arctic sea ice cover has lost on average around two-thirds of its thickness and now 70 percent of the sea ice cap is made of seasonal ice, or ice that forms and melts within a single year. But at the same time that sea ice is vanishing quicker than it has ever been observed in the satellite record, it is also thickening at a faster rate during winter.

Study: Climate change could force outdoor workers to wake up far earlier

A new study published in Earth’s Future, a journal of the American Geophysical Union, indicates that if society tries to avoid the economic impacts of climate change on outdoor labor by shifting working hours, outdoor workers in many regions will need to start working well before dawn at the end of this century to avoid the effect of excessive heat stress.
