It's pretty disingenuous to cut the graph at the beginning of the ice age cycles. This tricks people into believing that the current level of CO2 has never been seen before.
So I'd ask what parts of climate change are falsifiable?
- Is the climate changing? Of course, but it has also been changing for all of earth's history.
- Are humans and other organisms contributing? Yes but organisms have contributed to climate change for all of earth's history. Blue-green algae put oxygen into the atmosphere, plants sequestered huge amounts of carbon.
- Are we at a historically unprecedented level of carbon? No, the earth was previous at something like 200x the atmospheric CO2.
- Will 2x the atmospheric CO2 cause mass death? Probably not, we know life thrived in the past on a much warmer and more CO2 rich globe. Many more humans die of cold rather than heat.

In contrast, this is a much more contextually accurate graph: https://today.tamu.edu/wp-content/uploads/2021/06/66millionY... ref: https://today.tamu.edu/2021/06/14/ancient-deepsea-shells-rev...
