When great granddad was born in 1860, atmospheric CO2 was ≈288 ppm. Not a Goldilocks 280, but still manageable.
"The history of anthropogenic fire offers a useful way of understanding the Anthropocene. It provides a continuous narrative, particularly for the transition into the burning of fossil biomass, and it proposes an analogue—the fire equivalent of an ice age—by which to imagine the future."
From Pleistocene to Pyrocene: Fire Replaces Ice
Terrestrial fire is a unique feature of Earth, and fire uses a unique marker of human activity A major inflection in human fire history occurred when people turned to burning fossil biomass rather ...

It's not quite "gobsmackingly bananas" but monster forecasts for the record El Nino brewing the Pacific Ocean get pretty close. Here's what to make of it in my first for @nature.com: 🧪 www.nature.com/articles/d41...
This El Niño is set to be the largest on record by a ‘mind-blowing margin’
Forecasters predict that the monster climate pattern will combine with global warming to push global temperatures in 2027 to new heights.

. After human activities emit CO2 into the atmosphere, it stays there for decades. Centuries. It's cumulative. So who leads at any given moment in time is almost irrelevant. But the fact that cumulative U.S. CO2 emissions *dwarf* those of all other countries is *highly* relevant. To lots of things.
