Ocean temperature reconstructed over the last 700,000 years

-

Bern’s ice core researchers were already able to demonstrate in 2008 how the concentration of CO2 in the atmosphere has changed over the past 800,000 years. Now, using the same ice core from the Antarctic, the group led by Bernese climate researcher Hubertus Fischer shows the maximum and minimum values between which the mean ocean temperature has fluctuated over the past 700,000 years. The results of the reconstruction have just been published in the journal Climate of the Past.
