Climate Change

• Great Global Warming Swindle - this presents the opposite point of view, that global warming is due only to sun variation, but its credibility is under question.

In this paper, the researchers studied the abundances of two isotopes, C-14 and Be-10, both of which are created with interaction with cosmic rays. The paper claims that the source of the two elements (tree trunks and ice sheets or ocean sediments) is very different but they show a correlation. Since the primary source of Cosmic Ray flux is the sun, these elements can be used to provide a history of solar variability.

The conclusion of this paper states:

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.
