[ RadSafe ] Solar radiation causes global warming

Yes, the graph shows a good correlation. However, that may be irrelevant if the graph is wrong. The following is from http://news.independent.co.uk/environment/climate_change/article2355956.ece 
"...Other graphs used in the film contained known errors, notably the graph of sunspot activity. Mr Durkin used data on solar cycle lengths which were first published in 1991 despite a corrected version being available ..."

This seems to be the same (pre 1991) graph that keeps floating around. If this graph was not wrong, I would be curious to know why no one has extended it to include more recent data (within the last 22 years!).

    If you look closely at the graph, you will notice that the data stops somewhere in the 1980s. I

  The data on the graph I sent only go to 1985, but what is important is that they show the incredible lock-step correlation between solar activity and global temperature from about 1870 to about 1985. For example, they show "global warming" from 1890 up until about 1940 and then the "global cooling" from about 1940 to 1970 that led to claims in the 1970's that we were in danger of a new ice age. Those claims were reported in the popular press. From 1970 until 1985 solar heating increased as did the global temperature. Now the popular press is reporting that we are in danger of being incinerated or at least drowned by melting glaciers. 

  There are no atmospheric carbon data that fit the earth's temperature data as well as the solar data.
