Solar Winds Cooling Warmist Doomsaying

By Timothy Birdnow

From The American Thinker, September 24, 2008

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…

‘factors other than solar’ include ocean oscillations – and these are additional candidates for the current cooling – with two cycles in the Pacific (PDO and ENSO) in their negative phases, the Arctic Oscillation now shfting (connected to the PDO) and the Atlantic also about to move out of a warm phase – it is like the ‘seventh’ wave phenomenon – all having peaked together between 1998 and 2005, turning in 2006-2008, with cool time ahead. Given this, it is difficult to extract Svensmark’s signal and allocate causes to the shift in albedo noticed by satellites (the ocean cycles will affect cloud too) – so it is a combination of natural factors that has overwhelmed the CO2 signal – which in my view was incorrectly ascribed and was due in large part to these cycles AND the solar increase from 1900-1990 of 230% in the power of the solar wind…..
