We don't know how fast the Earth is warming and we don't know how much of that warming is anthropogenic. The best "thermometers" we have are the UAH and RSS data sets, and they disagree by nearly 50% and historical data is constantly adjusted.
The only science actually settled is: the Earth is warming, disconcertingly fast, and humans are a large part of the process. Anything else even slightly more in depth is definitely not settled.
This is exactly what I said. In 2., not that humans are 100% all the cause of global warming, but definitely the dominating factor.
