I wish I was there for those accurate global temperature surveys and solar activity measurements back in 1880. And that chart, even if it had a snowball's chance in hell of being accurate, is only measuring sunspot activity.

Again, to accurately measure the quantity of radiation that hits us would require detectors almost everywhere. Right now there are several ways we detect solar radiation. Most accurate ground measurements use pyranometers and pyrheliometers. Most solar observation networks use satellites or a combination of satellites and ground stations. Check out this chart here. You see the column titled "Uncertainty in annual GHI values"? That is the one to pay attention to. 2-7% is claimed by SoloarGIS. And that network has only been in operation since 1994 and even that figure is BS. The ground stations that have been up since 1960 (not 1880!) have as high as an estimated 22% inaccuracy, but it's probably even much larger than that. The others don't even try to calculate how much they are off. But I'll tell you they are all off by large margins-margins so big that making an accurate assessment of the solar radiation hitting the earth at any moment are impossible - and, subsequently, knowing what amount of radiation hitting the poles and melting ice.

Trust me...I did data analysis for for the Solar and Heliospheric Observatory (SOHO) already back in the last century in the glorious Clinton era. ;-) I know all about the sun and how little we know about it. I also know how to manipulates statistics and calculations to BS anyone in either direction who wants to believe. If I wanted to support man-made "climate change" with engineered statistics spoken with authority - I could do that too. It's a game. Science institutions and universities are just like corporations, making themselves and their products (or research) needed.

C'mon ER, you can tell me! You've been playing the devil's advocate all these years because you're secretly one of those ultra-conservative Cuban-Americans that votes GOP every election...right? You like watching Robert, Bowser and Alcaray cheer you on, while you laugh because you are really even more conservative than Marco Rubio. Everytime they give you an attaboy, you get this perverse joy. But you never reveal your hand, because that would ruin all the fun.
