Recently US Senators considered a number of amendments to their Keystone pipeline bill, but none of them were in the proper format, or actually addressed the issue.
An appropriate legislative motion would read like this:
Whereas, Extent of global sea ice is at or above historical averages;
Whereas, Populations of polar bears are generally growing;
Whereas, Sea levels have been slowly rising at the same rate since the Little Ice Age ended 150 years ago;
Whereas, Oceans will not become acidic due to buffering from extensive mineral deposits and marine life is well adapted to pH fluctuations that do occur;
Whereas, Extreme weather events have not increased in recent decades and such events are more associated to periods of cooling rather than warming;
Whereas, Cold spells, not heat waves, are the greater threat to human life and prosperity;
Therefore, This chamber agrees that climate is variable and prudent public officials should plan for future periods both colder and warmer than the present. Two principle objectives will be robust infrastructure and cheap, reliable energy.
The underlying issue is the assumption that the future can only be warmer than the present. Once you accept the notion that CO2 makes the earth’s surface warmer (an unproven conjecture), then temperatures can only go higher since CO2 keeps rising. The present plateau in temperatures is inconvenient, but actual cooling would directly contradict the CO2 doctrine. Some excuses can be fabricated for a time, but an extended period of cooling undermines the whole global warming mantra.
It’s not a matter of fearing a new ice age. That will come eventually, according to our planet’s history, but the warning will come from increasing ice extent in the Northern Hemisphere. Presently US infrastructure is not ready to meet a return of 1950s weather, let alone something unprecedented. Public policy must include preparations for cooling since that is the greater hazard. Cold harms the biosphere: plants, animals and humans. And it is expensive and energy intensive to protect life from the ravages of cold. Society can not afford to be in denial about the prospect of the plateau ending with cooling.
