For context, this is one of my favorite climate graphs, showing 800,000 years of atmospheric CO2, including the massive run-up over the past century. We're now around 420 parts per million (ppm), more than anytime in 800,000 years (actually more than anytime in the past 5 million years) and completely outside the natural ups and downs in the record. This is the driver of the current #climate crisis.

@petergleick I love this graph too because it shows an unprecedented acceleration. I think we need to be able tell the #history of how this happened, which I do here: https://apocalypse-confidential.com/2022/09/10/the-autonomous-chemical-weapon-how-sentient-oil-took-control-of-our-history-part-two/

We need to see this as a political phenomenon, not an inevitable product of "human progress" or some BS like that.

@petergleick It is striking. Now, it's entirely possible that we'll find some calibration factor that massively changes the ice core numbers: this would be used as a "ACC isn't real" rallying point. The most stark section for me is from 1950 onwards where we have reliable data.

@dvavasour The ice core data are tremendously well vetted. Look for Vostok core papers on Google Scholar (or equivalent) for details. Here's a bit of background.

@petergleick me too
I use it every time I need to answer to those who say that climate change has always been a normal Earth's behaviour

That graph scares me more than the International Science report I read for a paper during my doctoral studies. Thanks for sharing.

@petergleick Wow. That’s a very telling chart

@petergleick what drives the natural ups and downs before humans step in? also - am I reading this correct that the massive last spike is only 20-30 years old? that can't be right?!
