“If climate disasters are to be averted, atmospheric carbon dioxide (CO2) must be reduced below the levels that already exist today, according to a study…by a group of 10 scientists…who…assert that to maintain a planet similar to that on which civilization developed, an optimum CO2 level would be less than 350 ppm…” Full Slice
“…researchers…have uncovered surprising effects of climate patterns on social upheaval and the fall of dynasties in ancient China…the study showed that the dry period at the end of the Tang Dynasty coincided with a previously identified drought halfway around the world, in Meso-America, which has been linked to the fall of the Mayan civilization.
The study also showed that the ample summer rains of the Northern Song Dynasty coincided with the beginning of the well-known Medieval Warm Period in Europe and Greenland…A second major finding concerns the relationship between temperature and the strength of the monsoons….” Full Slice
“…Over these 65 million years, the Earth has undergone several major warming and cooling episodes, which were largely mitigated by the expansion and contraction of sea ice in the Arctic…Currently, the Earth is in the midst of an interglacial period, characterized by retracted ice sheets and warmer temperatures.
In the past three decades, changes in Arctic climate and ice cover have led to several reorganizations of northern ocean circulation patterns….” Full Slice
So how strong might be the connection(s) if there are any ?
And a FAQ on climate models and some discussion.
