we don't understand the sun, the air or the ocean well enough
:... climate change remains a fascinating and important scientific subject. Climate dynamics and climate history are extraordinarily complex, and despite intensive study for decades, scientists are not yet able to explain satisfactorily such basic phenomena as extreme weather events ([[hurricane]]s, [[tornado]]es, [[drought]]s), El Nino variations, historical [[climate cycles]], and trends of [[atmospheric temperature]]s. The scientific uncertainties about all these matters are great, and not surprisingly, competent scientists disagree in their interpretations of what is and is not known.

:The current debates about global climate change are complicated by our not understanding the physics of the sun or of the earth’s atmosphere and oceans well enough to dismiss them as major causes of climate change on the earth. Dramatic climate changes like the [[medieval warm period]] at the time of the [[Viking]] settlements of [[Iceland]] and [[Greenland]] from about a.d. 900 to 1250, and the subsequent “little ice age,” from about 1250 to 1700, which led to extinction of the Greenland settlements, were certainly not caused by manmade changes in the concentration of [[carbon dioxide]] in the atmosphere.
