Open Letter to the Secretary-General of the United Nations
H.E. Ban Ki-Moon, Secretary-General, United Nations
First Avenue and East 44th Street, New York, New York, U.S.A.
November 29, 2012
Mr. Secretary-General:
On November 9 this year you told the General Assembly: “Extreme weather due to climate change is the new normal … Our challenge remains, clear and urgent: to reduce greenhouse gas emissions, to strengthen adaptation to … even larger climate shocks … and to reach a legally binding climate agreement by 2015 … This should be one of the main lessons of Hurricane Sandy.”
On November 13 you said at Yale: “The science is clear; we should waste no more time on that debate.”
The following day, in Al Gore’s “Dirty Weather” Webcast, you spoke of “more severe storms, harsher droughts, greater floods”, concluding: “Two weeks ago, Hurricane Sandy struck the eastern seaboard of the United States. A nation saw the reality of climate change. The recovery will cost tens of billions of dollars. The cost of inaction will be even higher. We must reduce our dependence on carbon emissions.”
We the undersigned, qualified in climate-related matters, wish to state that current scientific knowledge does not substantiate your assertions.
The U.K. Met Office recently released data showing that there has been no statistically significant global warming for almost 16 years. During this period, according to the U.S. National Oceanic and Atmospheric Administration (NOAA), carbon dioxide (CO2) concentrations rose by nearly 9% to now constitute 0.039% of the atmosphere. Global warming that has not occurred cannot have caused the extreme weather of the past few years. Whether, when and how atmospheric warming will resume is unknown. The science is unclear. Some scientists point out that near-term natural cooling, linked to variations in solar output, is also a distinct possibility.
Policy actions that aim to reduce CO2 emissions are unlikely to influence future climate. Policies need to focus on preparation for, and adaptation to, all dangerous climatic events, however caused.
