Climate change at work. Everything is extreme:

Temperatures in Colorado plunged 64 degrees on Thursday, the largest temperature drop the state has ever seen in October.

It’s also the 15th largest temperature drop over a two day period in Denver’s history, according to the National Weather Service.

At the Denver airport alone, the temperature dropped 55 degrees. CNN meteorologist Taylor Ward said at 2 p.m. on Wednesday it was 79 degrees and on Thursday at 2 p.m. the temperature read 24 degrees.

For the first time in recorded history, the average monthly level of CO2 in the atmosphere exceeded 410 parts per million in April, according to observations at the Mauna Loa Observatory in Hawaii.

…Research indicates that if unchecked, increased CO2 levels could lead to tens of thousands of pollution-related deaths, reach a point at which it slows human cognition, and contribute to rising sea levels, searing heat waves, and superstorms that scientists project as effects of climate change.
