Study using climate simulations Human-caused climate change fuels mega-fires in the Arctic

The Arctic has been experiencing record wildfires for years. Lukas Fiedler, a researcher at the Earth and Society Research Hub (ESRAH) at the University of Hamburg, has now been able to demonstrate: the extreme fire years 2019 to 2021 can be attributed to human-caused climate change. His study was published in the...

Climate policy – is it all it’s cracked up to be?

Actually, it’s all pretty straightforward: the European Union has set itself the goal of becoming climate-neutral by 2055, while Germany wants to do so by 2045.

UNESCO wants all at-risk coasts around the world to be “tsunami-ready” by 2030. Today, on the fifteenth anniversary of the tsunami that struck Japan on March 11, 2011, costing more than 18,000 lives and resulting in a meltdown at Fukushima Nuclear Power Plant, this goal has lost none of its urgency. To achieve it, twelve...

The hidden volcanoes of the northern Reykjanes Ridge

Volcanism in Iceland is well known above sea level. Our study shows that there is a “sweet spot” at certain water depths offshore Iceland where explosive volcanism can occur — however, the resulting volcanoes now lie hidden beneath the ocean surface.

This article was published first here.

When people think of Icelandic...
