Here is the article. http://www.journals.royalsoc.ac.uk/content/h844264320314105/fulltext.html

I won't copy it here since there are graphs that would be hard to include. The article looks at what energy and particles are hitting the earth over the last 25 years. Want to have your Cosmic Ray theories of cloud formation verified? Well they looked at that as well as the Sun's solar output.

The summary is this. As one would expect, the sun variability was seen in the weather patterns in the past and even in the first half of the 20th Century. And most of those studies involve proxies for the sun and earth's temperature before 1600. The expansion of thermometers and observation of the sun's sunspots give better and better resolution on these measurements through today.

This study looks at just the data from the last 25 years. This is a time when we could obtain measurements above the atmosphere itself for solar and space particles. And the measurement of temperatures is quite broad and includes satellite measurements over areas previously unaccounted for.

The conclusion is "There are many interesting palaeoclimate studies that suggest that solar variability had an influence on pre-industrial climate. There are also some detection-attribution studies using global climate models that suggest there was a detectable influence of solar variability in the first half of the twentieth century and that the solar radiative forcing variations were amplified by some mechanism that is, as yet, unknown. However, these findings are not relevant to any debates about modern climate change. Our results show that the observed rapid rise in global mean temperatures seen after 1985 cannot be ascribed to solar variability, whichever of the mechanisms is invoked and no matter how much the solar variation is amplified."

This definitive paper is one of dozens with the same conclusion. The rise in temperatures in the last 25 years, cannot be from outerspace. Everyone in science KNOWS that based simply upon the energy from outerspace (mainly the sun) the average temperature on earth should be below freezing. The reason our climate is warmer is Greenhouse Gases. Having removed the external input as a source for the rise in temperature one is left with explaining why in adding Greenhouse Gases to the atmosphere in the form of CO 2 and methane, why we WOULDN'T see a correlated increase in temperature.
