Research Reveals Sources of CO2 from Aleutian-Alaska Arc Volcanoes

Scientists have wondered what happens to the organic and inorganic carbon that Earth's Pacific Plate carries with it as it slides into the planet's interior along the volcano-studded Ring of Fire. A new study suggests a notable amount of such subducted carbon returns to the atmosphere rather than ...

European Bird Communities Move to Cooler Areas, but Mountain Ranges and Coastlines 'Control the Traffic'

A recent study shows that European bird communities have shifted northeastward in the past 30 years. These shifts are faced with obstacles such as mountain ranges and coastlines. Overall, bird communities are moving towards cooler areas but not fast ...

Mountains Vulnerable to Extreme Rain from Climate Change

A new study finds that as rising global temperatures shift snow to rain, mountains across the Northern Hemisphere will be hotspots for extreme rainfall events that could trigger floods and landslides -- potentially impacting a quarter of the world's ...

There May Be Good News About the Oceans in a Globally Warmed World

An analysis of oxygen levels in Earth's oceans may provide some rare, good news about the health of the seas in a future, globally warmed world. A study analyzing ocean sediment shows that ocean oxygen levels in a key area were higher during the Miocene warm period, some 16 million years ago when ...
