Solar Winds Cooling Warmist Doomsaying
Global warming alarmists face yet another challenge to their predictions of an inferno of doom. The solar wind is losing power, and is at a fifty year low, according to NASA.
The Ulysses solar probe reports a 13% drop in temperature, a 20% drop in density, and a 30% drop-off in the sun`s magnetic field, marking this as the weakest period of solar wind on record (records go back to the 1960`s).
What does this mean? The Heliosphere is thinning, and thus will block fewer cosmic rays. Heinrick Svensmark theorizes that an increase in cosmic rays reaching the Earth will drive cloud formation, increase the planet`s albedo, thus cooling it.
Is this the cause of the Earth`s unusually cool year? According to Anthony Watts, the Earth`s albedo reached a nadir in 1997, and has risen sharply since. Is this related to the weakening of solar activity? We`ve seen few sunspots in Solar Cycle 24, the solar conveyor belt has slowed to a crawl, and now the solar wind is bottoming out.
This will allow us to see if we are really in the throes of Anthropogenic Global Warming; if temperatures rise (and they haven`t since 1998) then factors other than solar activity are driving climate trends, if not then the greenhouse gas theory is falsified.
If a cooling trend continues, the climate alarmists will have to throw in the towel. Never fear; they`ll come up with a new cause to keep their adrenaline flowing! Probably ocean acidification, or the loss of bees...
