And way below any IPCC prediction based on CO2 influence.
Just something to point out here I'm not sure you are aware of.
A lot of the modeling shows runaway effects. If you'e ever seen how an avalanche progresses, a small disturbance can create a cascade and rapidly build up over a very short period and result in a much larger overall effect.
You never seen the opposite. This is the second law of thermodynamics. Entropy, and disorder tend to increase over time.
Thankfully for us, anthropogenic sources of CO2 are very small in the overall scheme of things and the climate has some built in buffers. I believe one of the most important of which is the increase in atmospheric water vapour as the temperature increases.
It would be easy to assume as the temperature goes up, the water vapour goes up, the cloud cover increases, and more sunlight gets reflected back into space. Problem solved.
That's not how it works though. What we tend to find is these changes produce ripples in other systems. The increase in clouds over land change wind patterns, they change the flow of currents in the ocean due to the temperature differentials. More cold water in some places, warmer water in others, more warm air in certain areas, more cold air in others. And so on and so forth.
We know these processes can happen because they happen naturally. I'm sure you are familiar with El Nino. It's an example of how the climate can be affected drastically by the small variations over a period of time.
The reason I'm bringing up these points is because I think you tend to have the opinion that humans can't influence the climate, and there's no way it could be as bad as they think. But it's really just a bad assumption.
The fact is small changes can have a very large overall effect, and they tend disrupt the natural order of things. We are beginning to see glaciers that have been there for hundreds of years disappear, almost over night in some cases. And we are beginning to see longer and warmer periods, as well as longer and colder periods all over the planet.
And this is also why you might want to be cautious with dismissing the IPCC predictions. As we factor in the changes that we observe over time the models are showing the potential for ripples in the climate that have pretty dramatic negative consequences. And I doubt it's because they like to deliver bad news.
