Devils advocate: The eocene period https://en.wikipedia.org/wiki/Eocene https://en.wikipedia.org/wiki/Eocene was roughly 50 million years ago and the Earth was 15 celcius warmer than it was today. We are worried about 1.5celcius, not 15 celcius. From that time, the Earth became ~20 celcius colder about 20,000 years ago. https://en.wikipedia.org/wiki/Last_Glacial_Maximum https://en.wikipedia.org/wiki/Last_Glacial_Maximum Which was 6 celcius colder than today. Did humans cause the 6 celcius in warming between 20 and 10 thousand years ago? For the last 10,000 years the Earth has bounced around +- 1 celcius and current day climate change in the last couple hundred years ago is less than that bouncing back and forth. What exactly have humans caused? The standard deviation of temp in the last 10,000 years has not changed. We can't be blamed for any of the other actual climate change. The climate changes and so far humans havent changed anything.
