I no longer worry. I'm extremely pessimistic about the impending climate change. I believe Sabine isn't pessimistic enough about what to anticipate. Consider the tundra methane emissions and the explosive release of methane-hydrates from the oceans, along with water vapor, a potent greenhouse gas. The disaster looming over all ecosystems (a mass extinction event) that will happen in decades and the doom-phase could last for 200,000 years. The chances of humanity surviving are incredibly slim, IMO. We can't colonize Greenland or Antarctica due to the lack of fertile soil, and it would take thousands of years to develop it. Without saying so, we don't have this amount of time.

I think extreme doomers like this create a shitty world to live in where you're surrounded by people that adopted an extreme "nothing matters the world is doomed soon" perspective that is depressing.

Ok, but are they wrong?

They are correct:

Daily Sea Surface Temperature (notice the new paradigm started in 2023 and extending into 2024):

Daily Surface Air Temperature:

Daily Sea Ice Extent (click on "Show Southern Hemisphere", also showing concerns of being low in 2023):

The most shocking is the sea surface temperature, but we see rising temperature in all layers of the troposphere. A factor that has dampened global warming for very long, since the last ice age, is the ocean's capacity for absorbing heat. If this gets saturated, and since surface waters don't mix much with deep waters.. If the same surplus heat equivalent to 15 hiroshima bombs per second today hits the surface, and rising. All that goes into heating air and surface, it's going to accellerate warming going forward. Early projections are in fact showing accelleration already.

That most people are incapable of emotionally processing this, is part of the problem.

Is 1+ enough of a trend to disregard most of the models? Is there no other explanation for the "new paradigm" of accelerating warming? You're saying that extreme warming scenario is now the correct science. I don't think there is a consensus about this.

It's not enough to call it a change of trend. I have another comment here where there are other, more temporary factors that also came into play. There's not consensus until after we see the new trend. Likely there are some temporary factors that will make the lines go down again when they wear out. But the overall trend might still be accellerating, just that it's going slower than normal human reference of time.

The increasing sea surface temperature is concerning because it directly is starting to harm millions of sea creatures that cannot adapt fast enough. There are multiple die-offs happening already that might be due to this.

What's concerning is that all the arrows are pointing just one way. The discussion is now wether it's accellerating or not..
