Alarmist climate science and the principle of exclusion | Watts Up With That?

[Paul MacRae] While Darwin rejected the principle of exclusion, at least as a primary scientific tool, alarmist climate science has not. Instead, the principle of exclusion is one of the most-cited arguments to support the anthropogenic global warming (AGW) hypothesis.

For example, in a 2010 interview with the BBC on the Climategate scandal, Climate Research Unit (CRU) head Phil Jones was asked: “What factors convince you that recent warming has been largely man-made?” Jones’s reply: “The fact that we can’t explain the warming from the 1950s by solar and volcanic forcing.” In other words, Jones is using the principle of exclusion: while he and his colleagues can’t prove that human activities are causing warming, they can’t find any other explanation.
