The BEST study does show that the Earth has warmed. However the report that Muller is stomping around with on cable news hasn’t been published in a peer reviewed journal evidently. But at least we can say that the Earth has warmed. That is not in doubt at this point. The cause of the warming of course is still in doubt.
It can be pretty safe to assume that we had an effect in the warming trend, but how large or little of an effect can’t be determined at this time. But keep in mind, the Earth’s climate is an extremely complicated system with all of sorts of factors including solar activity, volcanic activity, ocean currents, wind currents, the cloud system, cows, cosmic radiation, the alignment of the planets(I guess) and a shitload of other stuff I don’t know about.
I just don’t see how we can say we are the sole cause when there are so many other factors, especially when we don’t fully understand all of the Earth’s systems and functions yet. We are learning new things about our world every day. It seems like we are jumping to a conclusion that may or may not pan out.
One thing is for sure. We are a narcissistic species. Galileo was persecuted when he dared suggest that the universe doesn’t revolve around us. People have a difficult time with the concept that there are superior forces in the world and universe that are beyond our control.
After all, what gives the Earth the right to change the climate without our permission?
