Abstract
Improved knowledge of glacial-to-interglacial global temperature change yields Charney (fast-feedback) equilibrium climate sensitivity 1.2 ± 0.3°C (2σ) per W/m2, which is 4.8°C ± 1.2°C for doubled CO2. Consistent analysis of temperature over the full Cenozoic era—including ‘slow’ feedbacks by ice sheets and trace gases—supports this sensitivity and implies that CO2 was 300–350 ppm in the Pliocene and about 450 ppm at transition to a nearly ice-free planet, exposing unrealistic lethargy of ice sheet models. Equilibrium global warming for today’s GHG amount is 10°C, which is reduced to 8°C by today’s human-made aerosols. Equilibrium warming is not ‘committed’ warming; rapid phaseout of GHG emissions would prevent most equilibrium warming from occurring. However, decline of aerosol emissions since 2010 should increase the 1970–2010 global warming rate of 0.18°C per decade to a post-2010 rate of at least 0.27°C per decade. Thus, under the present geopolitical approach to GHG emissions, global warming will exceed 1.5°C in the 2020s and 2°C before 2050. Impacts on people and nature will accelerate as global warming increases hydrologic (weather) extremes. The enormity of consequences demands a return to Holocene-level global temperature. Required actions include: (1) a global increasing price on GHG emissions accompanied by development of abundant, affordable, dispatchable clean energy, (2) East-West cooperation in a way that accommodates developing world needs, and (3) intervention with Earth’s radiation imbalance to phase down today’s massive human-made ‘geo-transformation’ of Earth’s climate. Current political crises present an opportunity for reset, especially if young people can grasp their situation.
My basic summary (I am NOT a climate scientist so someone tell me if I’m wrong and I HOPE this is wrong for my children), scientists had dismissed hotter climate models due to the fact that we didn’t have historical data to prove them. Now folks are applying hotter models to predicting weather and the hotter models appear to be more accurate. So it looks like we’re going to break 2C BEFORE 2050 and could hit highs of 8C-10C by the end of the century with our CURRENT levels of green house gases, not even including increasing those.

I’m not at odds with people who don’t respect her. I’m at odds of people bringing up the same two videos over and over again. Should she have made those videos? No. We both agree with that. Does she owe an apology video for that? No, I don’t believe she does. YouTube is not a scientific journal, it’s a media outlet. Her main contribution to the channel is educating us on science and explaining things in ways we can understand. I accept that she will make mistakes sometimes because she is trying to put out way too much content than she has knowledge for. Unfortunately that’s how YouTube works, you either put out content or you lose algorithm power.
What I don’t have respect for is scientists who try to put people down just because they made a few mistakes and don’t go groveling and make a sorry video about it. It’s an insufferable and arrogant, snobbish attitude. Absolutely unnecessary. Point out the mistake and move on. I’m not a scientist and I greatly benefit from watching her videos because it helps me understand. Then I read comments like yours that make her sound like a hack. It makes me severely upset that we pick on a few bad videos instead of acknowledging the hundreds of useful videos. Absolutely ridiculous. I have no respect for rabid people like that and that’s what made me write that comment. And then at the end you take a shot at me for deciding to speak out about it. Fitting snobbish behavior. Have a good life
Well then to quote someone you might know, “get over it”. I believe that was you? Am I quoting you right?
If you want to be upset at someone, be upset at her for making and never having retracted the videos. As long as they’re out there people are going to point to them as reasons why she is not a reliable narrator. If she just wants to be a talking head, reading science, headlines etc. And giving insight as a particle physicist or a personal view of things from a particle physics standpoint. I’m all for it. That wasn’t what those videos were. They were well out of her wheelhouse. She was using it as a false appeal to her authority to push her feelings, not the facts.
If she wants to start a second channel to post her shit takes. Then she should do it. (By the way, I’m told it’s more than just the two videos now. There’s at least a third or possibly even a fourth one.) Keep the professional stuff all on one channel and all the ignorant bigoted stuff on a separate channel. She could call it something catchy like Sabine takes instead of shit takes. But I’m not going to point anyone to her channel or recommend anyone visit her channel as long as she mixes in bullshit like that with actual insightful analysis.
Again, if you have issues with me not liking her character. That is between you and her. It is not a me problem.
As a scientist, it is tremendously important for us, that people trust our science. We saw, what happens, if enough neglect science with Covid and now climate change. Scientists like her, who stray from their area of expertise and report false facts, just damage our reputation. I mean, you seem to have a pretty bad opinion of scientists.
Of course people can make mistakes. That’s actually a fundamental principle of science to be wrong a lot. It’s how you handle these mistakes, that matters. Adapt your views to the new information, do not stick to wrong facts, because you don’t like to admit, that you were wrong.
The problem with people like her is, that they gain trust by making videos about topics, where they are very knowledgeable. Then they use this trust for other content and they do not put any disclaimer about that in it. So people who watch it and are not knowledgeable in the topic of the video think, that they will get the same quality. But they don’t. We have enough misinformation swirling around, we don’t need more published by reputable persons.
You write yourself, that she describes stuff in a way, that you can understand it. But how do you judge, if she explains a topic correctly according to the current state of science, if you have no clue about it yourself? She could just bullshit you on every video without you knowing.
