An ice core study to determine the timing and duration of historical climate stages
Ice core records are rich archives of the climate history during glacial-interglacial cycles over timescales of up to ~800 kyr before the present. In ice core studies, the accurate and precise dating of the core samples is ...

Scientists find deep-ocean evidence for Atlantic overturning decline
A new study has found evidence from the deep ocean that the Atlantic meridional overturning circulation – a system of currents that brings warm water from the tropics to the North Atlantic region and keeps its climate more ...

Rise in temperatures and CO2 follow each other closely in climate change
The greatest climate change the world has seen in the last 100,000 years was the transition from the ice age to the warm interglacial period. New research from the Niels Bohr Institute at the University of Copenhagen indicates ...
