Here is a brief summary of what I think:
1. CO2 levels are rising rather steeply - this is known.
2. The CO2 is nearly all manmade - this is known (from isotope studies). We can take 1 and 2 as facts.
3. The mean global temperature has been rising faster than can be expected from any known natural phenomenon. I'd take this as 90+% true.
4. There are models that variously show our climate should get considerably warmer in the future if nothing is done , this is a statement of fact.
5. "We" collectively show little real sign of interrupting this CO2 trend soon enough to prevent significant warming, if the models are correct. I'd take this as 90+% true also. Some here disagree, but they seem not to have much of a factual basis for it.
6. Warming of 3°C or more would be bad in many ways, perhaps good in some ways. Sea level rise would be a problem. Adverse impact to oceanic systems likely will be bad. Our oceans provide the primary carbon sink, not forests. CO2 is less soluble in warmer water than cooler.
7. I hope the models are too extreme in their predictions. I don't know if they are, but climate, in my view, is extremely complex and the models could well be over simplifying various feedbacks, for better or worse.
Now, if someone thinks wind and solar and fusion and batteries and EVs can really alter Item 5 above, OK with me, I clearly do not. The simple math to me looks inexorable and I view all these accords and promises and targets as being political BS and spin.
Show me .... the money.
