:sad:OH! my! god! What will AlGore do?
Call the sicko guy.
Global warming may have peaked and things are going downhill from here!
Global Warming and Solar Radiation
By D. Bruce Merrifield
Overview
Without the impact of solar radiation, the temperature on the earth would be about the same as the temperature of space, which is about -454 F. The amount of radiation reaching the earth is about 1,368 watts per square meter. This is a vast amount of energy, which would require the simultaneous output of 1.7 billion of our largest power plants to match. About 70 percent of this solar energy is absorbed and 30 percent is reflected. However, the amount of solar energy reaching the earth is not constant, but varies in several independent cycles of different degrees of magnitude, which may or may not reinforce each other.
These cycles include a 100,000-year cycle, which results from the elliptical orbit of the earth around the sun, a 41,000-year (obliquity) cycle, which results from the tilt of the earth on its axis, a 23,000-year cycle which results from "climatic precession" or changes in direction of the earths axis relative to the sun, and an 11-year sunspot cycle, during which solar radiation increases and then declines. The most recent sunspot radiation cycle peaked in the year 2000, and currently is approaching a minimum. Curiously, NASA and the Russian Observatory both report that total solar radiation now has peaked, and all these cycles may be simultaneously in decline
Each 100,000-year peak in radiation appears to last about 15,000 to 20,000 years, and each has been coincident with massive surges of carbon dioxide and methane (the green house gasses), into the atmosphere, causing de-glaciation of the Polar and Greenland ice caps. Surges of these greenhouse gasses have always been vastly greater than the amounts currently being generated by burning fossil fuels. For example, the most recent 100,000-year cycle raised sea levels 400 feet in the first 10,000 years, but since then sea levels have risen very little. In the current warming period, sea levels are rising only about 3 millimeters per year, and temperatures over the last 100 years have risen a modest 0.6 of a degree C.
