Plankton as a climate driver: A new view on past climate change

2

Fluctuations in the orbital parameters of the Earth are considered to be the trigger for long-term climatic fluctuations such as ice ages. This includes the variation of the inclination angle of the Earth’s axis with a cycle of about 40,000 years. Marine scientists have now shown by using a new model that biogeochemical interactions between ocean and atmosphere could also be responsible for climate fluctuations on this time scale.
