what are their goals? Contrarians mostly not climate scientists
Example: news weathermen are not climate scientists
Contrarians mostly a U.S. phenomenon Increasingly powerful; dominate US right-wing agenda Supported by fossil fuel, libertarian think tanks
Exxonsecrets.org Greenpeace has details
Contrarian goals

Four Levels of Contrarianism
and why they are wrong There is no global warming GW
Fundamental distortion of the facts
There is GW, but we are not causing it Irrelevant ancient data + ignore science and models
There is GW + we are causing it, but there areno bad consequences Ignore expert warnings from many different fields
There is GW + we are causing it + there are badconsequences, but its too expensive to mitigate Outlier economics, ignore green energy benefits

The Nature of Science
Science is knowledge, a web of facts and theory,together very strong But, science is not mathematics
Mathematics: one chink or a missing fact or minor error invalidates a proof
Science: never proves, only degrees of certainty
Scientists are already skeptics, need persuasion BUT once persuaded, need good reasons to change
Scientists in the field publish in journals Peer review acts as a good (not perfect) filter

Contrarian Distortion of Science,
Tactics, Attacks Contrarian claims are not science
Wrong, misinformed, irrelevant, distorted, cherry-picking Ex: Sun responsible for recent global warming = wrong
Good description = Cargo-Cult pseudoscience (Feynman)
Common contrarian tactics are not scientific Use mass media (not peer-reviewed journals) Copy Big Tobacco doubt on smoking danger tactic Nitpick, turn molehills into mountains, falsely generalize Try to put science in the courtroom, with lawyers
Swift-Boat attacks on science and scientists Contrarian op-eds, right-wing politicians and blogs Some extremist threats of violence to scientists

Solar Fluctuations did NOT cause
global warming since 1980 Suns output is just Oscillating: NO trend
Contrarian conjecture recent solar influence: False

Contrarian Attacks
Wrong, Irrelevant, Cherry-picking Contrarian Global Cooling Conjecture => Wrong
Cherry-picks the starting date 1998, indefensible 1998 high temperature due to huge El Nio weather effect
Hacked emails => Irrelevant to science results Investigations exonerate Professors Jones, Mann Climate science results, existence of global warming, climate
data, models, projected impacts are NOT affected
Himalayan glaciers => Cherry-pick attack IPCC
2007 IPCC reports, summarize work, 3000 pages One paragraph wrong. Nothing is perfect. Glitch. Used as unwarranted excuse to attack / discredit IPCC
Ref: Realclimate.org , exhaustive AP email review

Shoe is actually on Other Foot Contrarians distort data
Medieval warming period was NOT global
Contrarians distort meaning of global warming
Does NOT mean warming everywhere, every day Contrarians distort uncertainty
Demand unattainable 100% certainty from scientists Contrarian conjectures - just wrong
Contrarians distort funding Salaried scientists in it for the money - ridiculous Contrarians hide funding by fossil fuel, libertarians
Known: $100,000 for one contrarian; $11,000 fee for lecture
