You know, it really bothers me that the EPA has come to heel with the environmentalist lobby and pandering Obama administration and made the declaration that carbon dioxide (CO2) is now to be considered a dangerous pollutant and major cause for global warming.
This is such tosh that it makes my scientifically trained brain positively hurt.
Don't any of these people know basic botany, biology and meteorology?
Botany: photosynthesis needs carbon dioxide to work.
Biology: without photosynthesis we would run out of oxygen, essential to life as we know it on Planet Earth.
Meteorology: water vapor is the major "pollutant" in the atmosphere when it comes to controlling the atmospheric temperature. Carbon dioxide is only a minor constituent.
So, why doesn't the EPA and everyone else declare water vapor a dangerous pollutant? Humans make an awful lot of water vapor. After all, the "smoke" escaping from thermal power station cooling towers is actually water vapor even though the environmentalists will have you believe it's the product of combustion.
Coming back to Earth, for a moment, water vapor in the atmosphere has always been around - think clouds!
