Climate Scientist responds to Sabine Hossenfelder on Climate Sensitivity

How hot will our planet actually get? Climate scientists try to answer this question by evaluating the “climate sensitivity”. And if you’ve watched the recent Sabine Hossenfelder, you may be left with the impression that climate change wasn’t much to worry about… but now it is. So I’m here to explain what the evidence is actually showing us, and why the situation is a little more nuanced than Sabine’s commentary may have suggested. And crucially I break down how climate scientists arrive at a number for the crucial “climate sensitivity”, to give us a sense for how much global warming we’re in for.
