Trenberth, 2011:
Climate change attribution - null hypothesis: no human role
“science community much too conservative .. too many authors make Type II errors” (accept the null hypothesis in error) – ie conclude any particular extreme event has no anthropogenic (human) component”

“Global warming is contributing to a changing incidence of extreme weather because the environment in which all storms form has changed from human activities”

Oreskes & Conway (2013):
“Western scientists built an intellectual culture based on the premise that it was worse to fool oneself into believing in something that did not exist than not to believe in something that did. Scientists referred to these positions as “type I” and “type II” errors, and established protocols designed to avoid type I errors at almost all costs”.
