Siberian tundra could virtually disappear by mid-millennium

AWI study shows: only ambitious climate protection measures can still save a third of the tundra

[25. May 2022]  Due to global warming, temperatures in the Arctic are climbing rapidly. As a result, the treeline for Siberian larch forests is steadily advancing to the north, gradually supplanting the broad expanses of tundra which are home to a unique mix of flora and fauna. AWI experts have now prepared a computer simulation of how these woods could spread in the future, at the tundra’s expense.


Mikroplastik in der Atmosphäre

Micro- and nanoplastic from the atmosphere is polluting the ocean

In a new study, an international team of researchers investigates the atmosphere as a relevant source of plastic pollution in our planet’s waters

[Translate to English:] Meeresströmungen
[10. May 2022]  According to estimates, by 2040 the level of plastic pollution could reach 80 million metric tons per year. Plastic particles have now been detected in virtually all spheres of the environment, e.g. in water bodies, the soil and the air. Via ocean currents and rivers, the tiny plastic particles can even reach the Arctic, Antarctic or ocean depths. A new overview study has now shown that wind, too, can transport these particles great distances – and much faster than water can: in the atmosphere, they can travel from their point of origin to the most remote corners of the planet in a matter of days. In the journal Nature Reviews Earth and Environment, an international team of researchers – including experts from the Alfred Wegener Institute, the Institute for Advanced…

The global “plastic flood” reaches the Arctic

A new AWI-led study shows: there is now a concerning degree of plastic pollution in the Arctic Ocean

[Translate to English:] Snow samples from Arctic sea ice
[05. April 2022]  Even the High North can’t escape the global threat of plastic pollution. An international review study just released by the Alfred Wegener Institute shows, the flood of plastic has reached all spheres of the Arctic. The plastic is not only a burden for ecosystems; it could also worsen climate change. The study was just released in the journal Nature Reviews Earth & Environment.

Dramatic warming in the Arctic

HALO-(AC)3 field campaign investigates a worrying phenomenon

Spitzbergen
[18. March 2022]  In mid-March 2022, there was a massive influx of warm air into the Arctic, with several unusual phenomena such as heavy rain over the sea ice and massive clouds reaching almost as high as in the tropics. The international research campaign HALO-(AC)3 is investigating the processes causing the above-average increase in temperatures in the Arctic during the last decades that is suspected to modify the regional weather in the mid-latitudes, as well.


Further Education

“klimafit” – Learning About Climate Change at Our Doorstep

Courses on social decision-making and responsibility in climate protection rolled out nationwide as part of the National Climate Initiative

[01. March 2022]  Rising temperatures, extreme weather events like heavy rain and storms – climate change is becoming more and more visible, and Germany is no exception. In this regard, every region faces its own unique challenges. With the course “klimafit”, the goal of the Helmholtz Climate Initiative REKLIM, the WWF Germany and the Universität Hamburg is to prepare citizens for the effects of climate change at their doorstep. As part of the National Climate Initiative, the course will receive 2.2 million euros of funding over three years. In March 2022, the next round of courses will begin at 128 community colleges throughout Germany.
