Levels of heat-trapping greenhouse gases have surpassed those from any point in human history and by 2030 are likely to resemble levels from 3 million years ago when sea levels were more than 60 feet higher than today and the Arctic was forested and largely ice-free, according to a new paper by researchers at the University of Wisconsin-Madison.
During that period, known as the mid-Pliocene era, temperatures were warmer by between 3.2 to 6.5 degrees Fahrenheit, and there was no Greenland ice sheet. Though it is melting today, the ice sheet is still two miles thick at its highest point.
Resulting in arable land crisis, food crisis, water crisis, air crisis, disease epidemic, civil unrest, mass extinction ....chaos
Unintended consequences: population control ¯\_(ツ)_/¯
