The theory of planetary warming (as it presently stands) is highly questionable. Is anyone else out there aware that CO2 comprises only about .038 per cent of the entire atmosphere????
Earth's dry atmosphere: 78% Nitrogen, 21% Oxygen, .93% Argon, .038% a mere sliver of CO2, and the teeny amount remaining is made up of Neon, Helium, Methan, Krypton, and Hydrogen.
Water vapor in atmosphere: about 3 to 4% of atomsphere by volume near the surface of the planet, far less in the upper atmosphere.
Water vapor is the primary greenhouse gas, and the amount of water vapor in the atmosphere is more or less constant. During a warm period when the dinosaurs and plant life were absolutely flourishing all over this planet there was an enormously higher level of CO2 in the atmosphere than at present. Life was flourishing on planet Earth at that time. The CO2 in the atmosphere at that time comprised about 12% of the atmosphere, and it was due to major volcanic emmissions. That was over 300 times the present level of atmospheric CO2! This proved a boon to luxuriant plant life at the time, because plants "eat" CO2 and need it to survive. In time the CO2 moderated to its present level of .038% of the atmosphere. That's about 4 hundredths of a percent, folks! Wow, big threat! In the 1940s and 50s the media were freaked about global cooling and there were dire predictions of a possibly imminent new ice age. Ha. Ha. Now we're hearing the opposite scare story. I don't buy it.
The changes in the Earth's overall temperature appear to be cyclical in nature if you look at the geological record over the past few million years, and they are probably linked primarily to the changing (and cyclical) energies coming from the sun which is, after all, the active agent that causes this planet to be warm in the first place. We have been in a period of unusually high sun spot activity for the past decade...reputedly the highest in the last 1,000 years. That means a more active sun. That means a warmer planet Earth...for the time being.
However, I do sympathize with Rapaire's plight. Snow in May is simply just downright disgusting.
