Rahmstorf in the headlines as climate alarm bells grow louder over rapid warming and Atlantic circulation risks. German oceanographer, Potsdam prof. PhD Wellington.
Recent studies confirm that global warming has accelerated significantly since 2015, with the Earth heating at about 0.35°C per decade—nearly double the previous rate. February 2026 saw extreme rainfall and flooding in Western Europe, while Arctic sea ice reached its third-lowest extent on record. Compound heat and drought extremes are rising rapidly, increasing risks of flash droughts and ecosystem tipping points.
