Throughout many glacial periods life on earth flourished between glacial times. During glacial periods it was tough for life on earth, very tough. Geologically the warming periods were brief and glacial periods long and hard.
An interglacial or interglacial period is the warmer period of time between ice ages where glaciers retreat and sea levels rise. Over the last 450,000 years, glacials have lasted anywhere from 70,000 to 90,000 years whereas interglacials last approximately 10,000 years.
Their is a climate crisis in our near future. It is called “The Next Ice Age.” Note: when I say near future, it could be one or two thousand years or perhaps less. It will happen!
Absolutely right on the money, in fact the last interglacial was even much warmer than we are now.
And yes, as always in the cycle, we are late for the very real ice age that is coming soon in the cycle.
