Could 'cocktail geoengineering' save the climate?

Geoengineering is a catch-all term that refers to various theoretical ideas for altering Earth's energy balance to combat climate change. New research from an international team of atmospheric scientists published by Geophysical ...

Volcanic eruptions triggered dawn of the dinosaurs

Huge pulses of volcanic activity are likely to have played a key role in triggering the end Triassic mass extinction, which set the scene for the rise and age of the dinosaurs, new Oxford University research has found.

Portable mass spectrometer allows on-site gas analysis

Analyses of environmental gases which previously required months of laboratory work can now be carried out rapidly in the field. A group of Eawag scientists have developed a portable mass spectrometer allowing on-site measurements ...

First global maps of volcanic emissions use NASA satellite data

Volcanoes erupt, they spew ash, their scarred flanks sometimes run with both lava and landslides. But only occasionally. A less dramatic but important process is continuous gas emissions from volcanoes; in other words, as ...

Atmospheric aerosols can significantly cool down climate

It is possible to significantly slow down and even temporarily stop the progression of global warming by increasing the atmospheric aerosol concentration, shows a new study from the University of Eastern Finland. However, ...

Scientists inch closer to predicting phreatic volcanic eruptions

Throughout the centuries, volcanic eruptions have claimed hundreds of thousands of lives due in part to the lack of accurate signs indicating imminent eruptions. One type of a volcanic eruption, a phreatic eruption, which ...

Could 'The Day After Tomorrow' happen?
