Scientists discover cosmic factory for making building blocks of life
Scientists have discovered a 'cosmic factory' for producing the building blocks of life, amino acids, in research published today in the journal Nature Geoscience.
New model of Earth's interior reveals clues to hotspot volcanoes
Scientists at the University of California, Berkeley, have detected previously unknown channels of slow-moving seismic waves in Earth's upper mantle, a discovery that helps explain "hotspot volcanoes" that ...
Prehistoric climate change due to cosmic crash in Canada: Team reveals cause of global climate shift 12,900 years ago
For the first time, a dramatic global climate shift has been linked to the impact in Quebec of an asteroid or comet, Dartmouth researchers and their colleagues report in a new study. The cataclysmic event ...
Soot suspect in puzzling mid-1800s Alps glacier retreat
Scientists have uncovered strong evidence that soot, or black carbon, sent into the air by a rapidly industrializing Europe, likely caused the abrupt retreat of mountain glaciers in the European Alps.
Researchers find Europe's forests moving toward carbon sink saturation point
Coastal cities face rising risk of flood losses, study says
The world's 136 largest coastal cities could risk combined annual losses of $1 trillion (750 billion euros) from floods by 2050 unless they drastically raise their defences, a study warned Sunday.
Earth orbit changes key to Antarctic warming that ended last ice age
For more than a century scientists have known that Earth's ice ages are caused by the wobbling of the planet's orbit, which changes its orientation to the sun and affects the amount of sunlight reaching higher ...
Researchers devise a way to measure volatile organic compound exchange in the atmosphere
Ice ages only thanks to feedback
Ice ages and warm periods have alternated fairly regularly in the Earth's history: the Earth's climate cools roughly every 100,000 years, with vast areas of North America, Europe and Asia being buried under ...
New evidence that cosmic impact caused Younger Dryas extinctions
Climate change occurring 10 times faster than at any time in past 65 million years
The planet is undergoing one of the largest changes in climate since the dinosaurs went extinct. But what might be even more troubling for humans, plants and animals is the speed of the change. Stanford climate ...
'Highway from hell' fueled Costa Rican volcano
If some volcanoes operate on geologic timescales, Costa Rica's Irazú had something of a short fuse. In a new study in the journal Nature, scientists suggest that the 1960s eruption of Costa Rica's larges ...
