Those who ignore the geologic perspective do so at great risk. In fall of 1985, geologists warned that a Columbian volcano, Nevado del Ruiz, was getting ready to erupt. But the volcano had been dormant for 150 years. So government officials and inhabitants of nearby towns did not take the warnings seriously. On the evening of November 13, Nevado del Ruiz erupted, triggering catastrophic mudslides. In the town of Armero, 23,000 people were buried alive in a matter of seconds.
For ninety percent of the last million years, the normal state of the Earth’s climate has been an ice age. Ice ages last about 100,000 years, and are punctuated by short periods of warm climate, or interglacials. The last ice age started about 114,000 years ago. It began instantaneously. For a hundred-thousand years, temperatures fell and sheets of ice a mile thick grew to envelop much of North America, Europe and Asia. The ice age ended nearly as abruptly as it began. Between about 12,000 and 10,000 years ago, the temperature in Greenland rose more than 50 °F.

If an ice age hits, Africa should be prepared for billions of refugees from the Northern hemisphere. It will not wipe out humanity, but greatly restrict the inhabitable part of the planet to the equatorial regions.
This is 13 May. I still have the heat on in my house. This global cooling thing is real. On the bright side, I expect to save a ton of money on not having to have air conditioning this summer (even last summer we only used our air conditioner about two or three times).
