The Upside of Greehouse Gases

We are told, incessantly, that carbon dioxide is the main cause of global warming -- it is not. The primary source of surface heat is radiant energy from the sun. Minor heat comes from geothermal energy from volcanoes and hot rocks. Trivial quantities of local heat are brought to Earth's surface by humans using stoves, cars, boilers, engines and factories powered by mined fuels such as coal, oil, gas and uranium. Even using "green" energy such as ethanol, wind or wood affects temperatures by transferring solar energy from farms and forests, to be released eventually as waste heat in cities. Solar energy is more concentrated in equatorial areas and is moved pole-wards by the circulation of air (99.9% nitrogen, oxygen and argon), and by water and water vapour via evaporation, condensation and ocean currents, all driven by convection and Earth's rotation. Carbon dioxide plays almost no part in these dominant weather processes. Moreover, it does not burn, nor is it radioactive - it...(Read Full Post)
