Before anyone buys into the opinion expressed by Richard Badalamente regarding a carbon tax to fight global warming (In Focus, July 13), I encourage them to read the scientific studies available at www.look-to-the-skies.com/global_warming.htm. The scientific information at this site is far too voluminous to include here, but a few things stand out.
First, recent temperature fluctuations are within the historical fluctuations experienced over the last 1,500 years.
Second, changes in the Earth's temperature correlate with changes in the sun's energy output, rotation of the Earth, revolution of the Earth, and debris from comets, meteors, asteroids and volcanoes.
Third, there is no meaningful correlation between CO2 levels and Earth's temperature. In fact, during the ice age 450 million years ago, CO2 levels were more than ten times higher than they are now.
Never miss a local story.
Fourth, man-caused CO2 is less than 3 perecent of the amount produced naturally.
Fifth, virtually none of the predictions by climate alarmists have actually materialized.
We all want a clean planet, but before we create a tax on CO2 emissions, let's be sure the science behind it is sound, that our efforts would make a difference and there are no "unintended" impacts on our economy or quality of life.
