HI
We are in an eliptical & a circular orbit which changes every 100,000 years.
In the last 500,000 years there have been 5 global warmings and global freezings (ice ages).
Global warming is being used as an excuse to heap on more taxes, but that won't stop our orbit changing.
Although we really should stop chopping down so many trees, these are the CO2 sponges. But, then again Volcanoes spew out millions of tons of Sluphur Dioxide, a true greenhouse gas, that actually does eflect the sun back into space, the biggest preducer of CO2 are the oceans.
But, they cannot be taxed.....yet
