Climate modeling

A warming Arctic produces weather extremes in our latitudes

AWI experts develop a climate model that explains the faltering jet stream

Die Veränderungen im Jetstream werden zumindest teilweise vom Rückgang des arktischen Meereises verursacht, so das Ergebnis der Untersuchungen.
[28. May 2019] 

Using a newly developed climate model, AWI researchers are now able to show that the undulating course of the jet stream in winter and the associated extreme weather conditions, such as cold spells, are a direct result of climate change.

IPBES-Bericht

Half of the coral reefs have already been lost

AWI expert on the role of marine biodiversity in the IPBES report

[06. May 2019] 

Commentary by marine biologist Julian Gutt: since the changes taking place underwater are far less visible than those on land, it was all the more important that the IPBES pay due attention to the oceans in its Global Assessment report.


New Study

Veritable powerhouses – even without DNA

Parasitic algae from the dinoflagellate lineage have organised their genetic material in an unprecedented way

Whether human beings or animals, plants or algae: the cells of most life forms contain special structures that are responsible for energy production. Referred to as mitochondria, they normally have their own genetic material, in addition to that found in the nucleus. Uwe John and colleagues at the Alfred Wegener Institute have now identified the first-ever exception to this rule in a single-celled parasite. The mitochondria of the dinoflagellate Amoebophrya ceratii appear to produce energy just like our own mitochondria, but without any genetic material, as the team reports in the journal Science Advances.
