Occam’s Razor and Climate Change
...As Professor Phil Jones of the CRU once admitted in an interview with the BBC, the instrumental record contains periods of warming which are statistically indistinguishable from the 1990s warming – periods of warming which cannot have been driven by anthropogenic CO2, because they occurred before humans had made a significant changes to global CO2 levels.

Between 1860 and 1880, the world warmed for 21 years, at a similar rate to the 24 year period of warming which occurred between 1975 and 1998. There was simply not enough anthropogenic CO2 in the atmosphere to have driven the 1860s warming, so it must have been driven by natural variation....

Scientists: Government agencies use the peer review process to squash dissent
...“After 1970, politicians substantially expanded academic sectors,” write 30 scientists, including Nobel laureates Dudley Herschbach of Harvard University and Sir Richard Roberts of New England Biolabs.

“Peer review’s uses allowed the rise of priorities, impact etc, and is now virtually unavoidable. Applicants’ proposals must convince their peers that they serve national policies and are the best possible uses of resources,” the scientists continued in their letter to the editor in the UK Guardian newspaper. “Success rates are about 25%, and strict rules govern resubmissions. Rejected proposals are usually lost. Industry too has lost its taste for the unpredictable.”

Complaints that the scientific establishment is preventing dissenting voices from getting funding or published has been a major controversy among climate science. Dr. Richard Lindzen of the Massachusetts Institute of Technology has argued that “global warming alarmism” has been damaged the integrity of science.

“Global climate alarmism has been costly to society, and it has the potential to be vastly more costly,” Lindzen wrote. “It has also been damaging to science, as scientists adjust both data and even theory to accommodate politically correct positions.”...
