56 million years ago, the Earth experienced an exceptional episode of global warming. In a very short time on a geological scale, within 10 to 20’000 years, the average temperature increased by 5 to 8 degrees, only returning to its original level a few hundred thousand years later. Based on the analysis of sediments from the southern slope of the Pyrenees, researchers from the University of Geneva (UNIGE) measured the impact of this warming on river floods and the surrounding landscapes: the amplitude of floods increased by  a factor of eight - and sometimes even by a factor of 14 -, and vegetated landscapes may have been replaced by arid pebbly plains. Their disturbing conclusions, to be discovered in Scientific Reports, show that the consequences of such global warming may have been much greater than predicted by current climate models.

Crop losses for critical food grains will increase substantially with global warming, as rising temperatures boost the metabolism and population growth of insect pests, new research says.

Buried deep in the muck beneath ancient Arctic lakes, there are clues that can help scientists learn what the climate was like thousands of years ago — and what it could be in the future.

More intense and prolonged excessively hot temperatures in The Lone Star State have raised concerns over how global warming may impact this upward trend.

Hikers and trail runners be warned: Rattlesnakes and other venomous reptiles may bite more people during rainy years than in seasons wracked by drought, a new study shows.

Sunlight drives molecules far from equilibrium, enabling new chemical pathways.

A geostationary hyperspectral infrared sounder can provide significant support to meteorologists to improve local severe-storm forecasting, according to Dr. Jun Li, Distinguished Scientist at the Space Science and Engineering Center of the University of Wisconsin–Madison, and one of the authors of a recently published study. 

Adam Hernandez walked across a blackened woodland past logs smoldering near Shaver Lake, 200 miles north of Los Angeles in the Sierra National Forest. With each step, gray ash puffed from under his heavy boots, and tiny flames flickered through a thick layer of pine needles on the forest floor.

This year’s U.S. wildfire season has been extremely active: Twenty-five percent more acres have burned in 2018, beating the 10-year average.

A new study by scientists at the University of Bristol has shown that ancient global warming was associated with intense rainfall events that had a profound impact on the land and coastal seas.
