junk science

The now numerous special interest groups who continue to lobby for unnecessary and economically harmful carbon dioxide taxation need to appreciate that nature, not the world's governments, will determine future climate. Second, that there is no scientific evidence that warmings greater than the much-talked about 2C will cause environmental catastrophe; rather, this number is one plucked out of the air for reasons of political targetry and control. And, third, that to limit atmospheric carbon dioxide to 450ppm, also a widely touted figure, makes no sense, because past carbon dioxide levels attained more than 10 times this without known adverse environmental effects, while greening the planet.

Politically popular though it may be, the belief that atmospheric carbon dioxide is the primary driver of average planetary temperature is junk science. For instance, Earth experienced an ice age about 450 million years ago at a time when atmospheric carbon dioxide levels are estimated to have been 15 times the pre-industrial level.

It is simply science fiction to believe that 450ppm of atmospheric carbon dioxide and 2C of warming are magic numbers that somehow mark a "tipping point"in Earth's climate system. Rather, they are politically contrived targets, erected for the purpose of stampeding scientifically innocent citizens into a gaping corral of carbon dioxide taxation.

The simplest explanation for the mild warming that occurred in the late 20th century is that it was part of Earth's ever-changing pattern of natural climate change and the job of scientists is to seek evidence to test that interpretation. They have and literally thousands of scientific papers to date have described climate evidence that is consistent with natural change.

Despite all the efforts of the Intergovernmental Panel on Climate Change (IPCC), and the expenditure of about $100 billion of research money since 1990, no scientific paper exists that demonstrates that the late 20th century warming, or the past 10 years of cooling for that matter, fall outside the rates and magnitudes of past (geological) climate change.
