Sabine, I love how you tackle these questions in a honest way and very didatic. This is much needed today, because most people like us have an intuition of these tipping points but don't know enough to explain this to someone else who is a negationist.

There have been a tipping point in the past, first for the beginning of the ice period, then for its end. There have never been a stable climate on earth, and the man is hopeless in preventing the climate from changing. Tipping points flip all the time, several time a year, but we are not said. We are said only when the aim is to halt the Chinese from developing, using false arguments from roten science.

I love Sabine's videos, but I think she created something of a strawman here. Shellenberger did not say that "tipping points are unscientific" but that *_speculation_* about tipping points is unscientific (see 10:00). In other words, the models do not support some of the wilder speculations. Sabine effectively agrees at 10:50 but makes it look like a disagreement because of a misquote. Btw, the conditions for substantial weakening of the AMOC, let alone collapse, is way outside the worst case warming scenarios of any of the models. Paleoclimate evidence indicates that the AMOC did not shut down even during recent glaciations.

@O. M. Even that isn't true. There have been a period around 1100 - 1300 where the global temperature were even higher. It is a long lasting trend, and in fact it is no other that the end of the ice period. . Second, there have been an even shorter heat period at 2500 BC in Africa. It lasted only twenty years and tumbled the Egyptian old empire. . It is not anthropogenic climate change.

Clearest explanation of hysteresis I’ve ever heard. I’ve used hysteresis controls in audio gating devices for years, and looked up the term to figure out why they were called that. It remained a bit obscure to me until I watched your illustration. Thank you! So, yeah, tipping point coming, and when it tips, it’s going to get cold. Very cold. We’re kidding ourselves if we think we can stop it because carbon dioxide has nothing on solar particle forcing. Meanwhile, we should stop pollution, seek for better energy sources, and prepare for the next ice age.

@anatomicallymodernhuman51754 жыл бұрын
MRShockwave , It’s the effect of the solar wind on earth’s weather and climate. The sun and its planets have interacting magnetospheres that carry current in the form of waves in the plasma of the solar wind. Some of that flows along earth’s magnetic lines to the poles. More intense blasts compress the ionosphere and heat it up, which is visible as the auroras. It’s a relatively new field, and still not fully understood. So, it hasn’t made it into the climate models in a very significant way yet, even though we know its effects dwarf many more subtle contributions like the human ones.
