She is typically a very "anti-establishment" accessible science educator. When she talks about climate change she puts the onus on herself to actually make the arguments rather than just "pushing the consensus." This is very important. As somebody who is anti-academia myself, I am so annoyed at being told I am anti-science as well for being as such. Hearing the evidence laid out by somebody also willing to call out academia, but who does believe in climate change is WAY more effective than one more bludgeoning tool from a boot licking sycophant.
Want to have your discussion regarding "What to do?" regarding climate change? You need to stop treating people who want to know your arguments and see your data with respect first. Sabine is a great ACTUAL science educator and not merely a grifter, and (I suspect) just a modest honest person. She legit deserves clicking that subscribe button.
