Lest we forget, the Earth has always warmed up and cooled down, warmed and cooled, without man's help or involvement. And now we're wanting to spend $45 trillion in this country to make it stop. What hubris.
Global temperature fluctuations---larger weather patterns---are nothing new. Looking back in history we see a regular pattern of warming and cooling. From 200 B.C. to A.D. 600 saw the Roman Warming period of 800 years; from 600 to 900 A.D. the cold period of the Dark Ages lasting 300 years; from 900 to 1300 was the Medieval warming period lasting 400 years; and 1300 to 1850, the Little Ice Age lasting over half a century.
What a weather ride it's been and nary an SUV or coal fired power plant in sight.
Since our forebearers were coming out of the little age age when it last started warming up around the time of the Civil War, wouldn't it make sense that perhaps we're in a normal weather pattern of warming now?
What if all weather patterns were primarily caused by the sun and cycles of sun spot activity? What if CO2 levels were really a lagging indicator of warming (coming years after warming had comenced) instead of the more popularly held belief of it being a leading indicator? These are thoughts worth pondering.
