|Global cooling as significant as global warming, research shows |
A "cold snap" 116 million years ago triggered a similar marine ecosystem crisis to those witnessed in the past as a result of global warming, according to research published today in Nature Geoscience.
The international study involving experts from the universities of Newcastle, UK, Cologne, Frankfurt and GEOMAR-Kiel, confirms the link between global cooling and a crash in the marine ecosystem during the mid-Cretaceous greenhouse period.
It also quantifies for the first time the amplitude and duration of the temperature change. Analysing the geochemistry and micropaleontology of a marine sediment core taken from the North Atlantic Ocean, the team show that a global temperature drop of up to 5oC resulted in a major shift in the global carbon cycle over a period of 2.5 million years.
