1/15β« Dr. Belch (why oh why isn't she a gastroenterologist?) seems not to recognize the significance of the story.
Climate activists predicted that if Earth's average temperature got to 1.5Β°C above the pre-industrial (late Little Ice Age) baseline it would be a disaster. But they did, and nothing bad happened.
The significance of that is that it means the climate activists were completely wrong.

2/15β« In case you're wondering, the 4 known factors which caused 2023 to be so mild were:
1. A strong El NiΓ±o spike. And
2. IMO 2020 shipping regulations drastically reduced sulfate aerosol air pollution (The IMO says they resulted in "an estimated 46% decrease in ship-emitted aerosols," which equates to a sudden 10% decrease in total global SO2 emissions, which is a large improvement in a short time, with a significant warming effect). And
3. The unusual 2022 Hunga Tonga eruption, which humidified the stratosphere. And
4. Also a little bit of warming from the ongoing slow rise in atmospheric CO2 levels (though only about 25 ppmv/decade).
It's all good, though (unfortunately) #1 & #3 are temporary.

Q: And what was the result of all that warmth?
A: Nothing. Nothing bad, anyhow.
We still get storms, but they're no worse than in the past.

9/15β« Honolulu is arguably the best quality sea-level measurement record in the world. It's near the middle of the world's largest ocean. It has 119 years of continuous measurements, from a near ideal location, without even a single missing month of data. It shows:

10/15β« Note that there's been no detectable acceleration in the sea-level trend there. That's typical: some long measurement records show negligible acceleration, and others show none at all.

11/15β« In fact, the "global" (average) coastal sea-level trend is so slight & slow that in many places it is dwarfed by local factors, like erosion, sedimentation, and/or vertical land motion. @GretaThunberg's hometown of Stockholm is one such place.

13/15β« That's right: catastrophic famines are fading from living memory, for the very first time. For all of human history, famine (usually caused by drought) was one of the great scourges of mankind, the Third Horseman of the Apocalypse β until now!
@GretaThunberg 14/15β« If you're too young to recognized what a miracle that is, count yourself blessed. In large part because of elevated CO2 levels, catastrophic famines no longer happen.
