Let’s go back to basics, shall we?
- I believe that the Earth has warmed since 1850: I know this as a scientific fact. The warming is about 1.4 Fahrenheit in that time frame
- CO2 has increased in that time. Some believe that the danger threshold was 350ppm. If so, then why did warming spikes occur prior to that metric? Why were multiple Holocene warm period periods warmer than the current one? What cause the end of the last glacial period (which, technically, is still occurring, since there are glaciers)? Could there not be a more natural explanation?
- I believe Man does play some small part in the warming, mostly from things other than CO2. Land use, UHI, agriculture, landfills, even ocean pollution and ozone depletion. Consider that it is a fact that much of the warming is occurring at night, or, I should say, we do not get the radiative cooling that should occur.
- Let’s skip all the other random thoughts, and go to the big one: the argument is not about warming, it is about causation. Period. I have had arguments, not discussion, argument, with folks on the Right who claim there has been no warming. They’re deluded. I don’t believe in Creationism, but I’m willing to listen to them (not believe them, mind you) because at least they are arguing from a religious POV. The scientific facts show warming.
- The argument is about what has caused the Modern Warm Period warming.
- And, finally, the Earth has warmed around 1.4F, but what has caused this to occur. This is the crux of the debate.
Oh, by the way, I’m arguing causation, not warming. Hope that clears it up.
