there is something a little fishy about this graph. actually, it is the same thing that bothers me about long range data which AGW folks like to point at frequently to support their claims.Felix wrote:
but, over the last fifty years, the sun’s output has decreased slightly: it is radiating less heat.....it's pretty easy to measure the activity of the sun pretty accurately from here on Earth and from the orbiting satellites above it, so it is hard to ignore the discrepancy between the facts and the argument that the sun is causing the rise in temperatures, which to the best of our knowledge, is the only thing that could drive significant planetary wide temperature increases on other planets...
as far as this graph you've presented, I'll ask you for the second time to provide where it comes from and to explain how the "OBSERVED DATA HAS BEEN ALTERED"....
notice how the data in this graph over the last 60 or 70 years follows a very steady cyclical pattern with just one abberation where one of the high cycles kind of sputtered out.
notice how prior to that, there were still cycles, but, they were all over the place.
why is that?
maybe the sun had a bad drinking problem up until about 70 years ago.
or maybe, just maybe, measuring devices and measuring techniques have improved a smidge. just a hunch.
same thing goes with the ozone hole. when did the ozone chicken littles start crying about the hole? they started crying about the time we aquired the capability to observe this change. i suspect, actually, i'm fairly damn certain that hole is also a function of, get this now, the activity of the fukking thing that causes it!!!!!
