Climate science moves in one direction, the AAAS moves in the other.
Paul C. Knappenberger is assistant director of the Center for the Study of Science at the Cato Institute.
In its new report on the risks from human-caused climate change, the American Association for the Advancement of Science (AAAS) sets climate science back rather than “advancing” it. The report, counterfactually titled “What We Know,” is more an account of what the scientific community thought it knew about a decade ago than an up-to-date telling of current understanding.
Not surprisingly, the group ignores the fact that climate science is moving in a direction that increasingly suggests that the risk of extreme climate change is lower than has been previously assessed. Instead, the AAAS continues to play up the chance of extreme outcomes with the intent of scaring us into taking action — action that would have little impact on either future climate change or the risks therefrom.
The AAAS largely appeals to its own authority in trying to persuade us to believe its conclusions and yet informs its authority with old and obsolete science.
Nowhere is this more true than in its justification for highlighting the risks of “abrupt climate change” and in its faith in the ability of climate models to provide reliable and informed guidance regarding the probability of extreme climate changes’ occurring in the future.
