Earth’s climate regulates itself

Statistical analysis of Earth’s climate indicates that the stabilization mechanism dampens strong climate fluctuations. This could have contributed to the fact that the Earth never got too hot or too cold for life for billions of years. According to a report by Konstantin W. Arnscheidt and Daniel H. Rothman of the Massachusetts Institute of Technology, temperature fluctuations over periods of up to 400,000 years are no greater than temperature fluctuations over timescales of about 4,000 years. However, one would expect for statistical fluctuations that the longer the time period, the farther apart the maximum and minimum temperatures would be. The result indicates that a mechanism that stabilizes the Earth’s climate over such short periods of time, The team writes in the journal Science Advances..
