Once Again – How We Know that Humans are Causing Climate Change

New video by Sabine Hossenfelder which is, regrettably, quite germaine in the era of revived climate denial memes.
It may not move Uncle Dittohead, but could be helpful for those asking good faith questions.

Additional supporting info as always, comes from NASA.

In addition, as I’ve often pointed out, one could rightfully assert that the surest indicator that one’s physics is correct is the ability to make predictions. If you used your understanding of physics to make a prediction about the earth system, say, 40 years ago, and that prediction is now playing out – it’s a pretty good indicator that your physics has some mojo.
If you have not seen this Yale Climate Connections video, you should, and book mark it.

  1. Sabine explained this very well all in just over 6 minutes and used good graphic aids. Hope the jury on climate scientist Michael Mann’s case are up to speed.

    “It looks like their defense in the defamation case is just to defame Dr. Mann even more strongly,” Bill Nye, a friend and supporter of Mann who has attended the proceedings, told DeSmog. “We’ll see. It’s up to the jury.”

  2. Surprised she didn’t include the basic stoichiometry of AGW, ie, the amount of fossil fuels burned since 1850 is in good agreement with the amount of CO2 observed in the air and ocean acidification.
