We have a new sunspot: www.spaceweather.com Problem is that it is another last-cycle sunspot — which means the cycle that should have started months ago just isn’t starting.
Re sunspots: These are a result of magnetic activity in the sun. Fewer sunspots or a late starting cycle indicate less magnetic activity. This means less solar wind, which in turn means more cosmic rays from space reach Earth. That in turn means more condensation of water vapor in the atmosphere into clouds (part of cloud formation is cosmic rays ionizing dust particles in the atmosphere which then attract water vapor forming water droplets, i.e., clouds). In other words, more clouds. That has a net cooling effect and also incidentally results in more rain (see Midwest floods).
Now, the AGW crowd has tried to prove that the above doesn’t happen with statistical “studies,” computer models, etc. But the actual underlying physics is pretty bulletproof.
PS Some of the interactions are more complex. For example, why are the east coast and the midwest unusually cool while the west is getting blasted with a heat wave? Dunnno. But the fact that April and May were pretty cool globally and June is shaping up that way lends credence to these theories re sunspots and climate.
The evidence of anthropogenic global warming pretty much boils down to effects of computer programs interpreting other computer programs.
The same goes for allegations concerning CFC emissions being the cause of the ozone layer depletion.
In the case of anthropogenic global warming, something the media, most politicians and even a lot of businesses of various sorts seldom acknowledge (or even fail to realize themselves) is that most scientific experts who warn of global warming being caused by man ADMIT there is actually very little evidence of this. Most of them are ALSO saying we can’t afford gamble though and similar things, but that is something completely different.
