2. That does in fact increase temperature long term. That has been measured. Only a fact if CO2 is the only variable, ignoring all other variables that the environment has to offer is bad science.

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. Exact outcomes are impossible 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. It is a fact that that is our best prediction, not a fact that it will happen.

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. No possible way you could state the outcome of the deal as fact

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. Continue for how long?500 years? one of these seems like a fact the other, yet another prediction.

7. The oceans will rise. Period. How much depends on many factors difficult to predict. They have risen slightly might continue to buy may also fall based on may factors that are impossible to predict.

8. The warming will not stop in 2100. Not a fact but again a prediction

Those are the facts. All else is supposition and politics, on both sides.



People seem to be confused as to what exactly a fact is. Predictions, assumptions, feelings, trends, etc... are not facts.
