yes a man named al gore.

The sun is burning more Helium than Hydrogen lately which has increased its thermal emissions slightly. The fact has been noted which has given rise to the Global Warming fan fair with its additional assault on CO2 emissions. That would be a greater problem if the planet were not robustly self regulating of its temperature. The public concern expressing a need for change is desirable because the advance in industrial efficiency requires changes in industry which is  beneficial to our economy.

Al Gore pushed the global warming Hooey just to sell his Book and movie!

I suspect tectonic plate movement and that includes volcanic activity has far more influence on the climate than all the automobiles ever made.
