The Arctic: Interglacial period with a break

Reconstruction of Arctic climate conditions in the Cretaceous period

FRANKFURT. Scientists at the Goethe University Frankfurt and at the Senckenberg Biodiversity and Climate Research Centre working together with their Canadian counterparts, have reconstructed the climatic development of the Arctic Ocean during the Cretaceous period, 145 to 66 million years ago. The research team comes to the conclusion that there was a severe cold snap during the geological age known for its extreme greenhouse climate. The study published in the professional journal Geology is also intended to help improve prognoses of future climate and environmental development and the assessment of human influence on climate change.

The Cretaceous, which occurred approximately 145 million to 66 million years ago, was one of the warmest periods in the history of the earth. The poles were…
