Yeah but here are the facts:
3. However, the effects are complex and there are interrelationships. For instance, ocean warming evaporates more water, which makes more clouds, which deflects sunlight to some extent. Therefore the EXACT outcomes are difficult to predict.
4. The models keep getting better as more data is measured. Our best predictions right now are that the world average temperature will rise between 3.5 to 5.2 decrees Centigrade by 2100.
5. The Paris accord, which President Trump wisely scrapped, would only have changed this outcome by about 0.2 degrees. It was not worth its cost to the US.
6. 75% of all CO2 now in the atmosphere will stay there for 500 years. If we stopped all fossil fuel burning right now, the earth would continue to warm.
Those are the facts. All else is supposition and politics, on both sides.
Those numbers are no better than the others posted up a decade ago, which were very wrong.
The estimates have been terrible, and thats not even factoring in the long term feedback mechanisms you allude to in #3.
Saying "FACT" and .2 deg and 5.2 by 2100 is a freaking joke and you are kidding yourself, but not everyone, that its more than a ballpark guess.
And THAT, is fact.
