A recent study has finally shed light on how, despite weak solar radiation and moderate levels of greenhouse gases, massive ice melt and significant sea level rise took place.
The hottest period on Earth in the past million years occurred approximately 400,000 years ago. During this time, the Northern Hemisphere had even less ice than it does today, and sea levels were about 10 meters higher than current levels.
Surprisingly,
solar radiation, a key factor in heat waves, was relatively weak, and
greenhouse gas concentrations were lower than they are today. This
seemingly inexplicable period in Earth’s history has been termed the
“MIS 11c paradox.”...<<<Read More>>>...
