Solar Driven Climate Change Leads To Global Cooling, Not Warming

Here is a very sobering essay about climate change. The author presents information that is exactly the opposite of what we usually hear. He predicts coming global cooling, not warming. He also says carbon dioxide emissions are good for the climate as we want to keep it as warm as we can for as long as we can. Let's see how this idea plays out.

Solar Cycle 24: Implications for the United States
By Geologist David Archibald.
Excerpts:
I will demonstrate that the Sun drives climate, and use that demonstrated relationship to predict the Earth's climate to 2030. It is a prediction that differs from most in the public domain. It is a prediction of imminent cooling....I will show that increased atmospheric carbon dioxide is not even a little bit bad. It is wholly beneficial. The more carbon dioxide we can put into the atmosphere, the better the planet will be - for humans, and all other living things....

We have 29 years of satellite temperature data. It shows that the temperature of the Southern Hemisphere has been flat, with a slight increase in the Northern Hemisphere. Note the El Nino peak in 1998. Globally, we have had 10 years of temperature decline since that peak in 1998, with a rate of decline of 0.06 degrees per annum. I am expecting the rate of decline to accelerate to 0.2 degrees per annum from the end of this decade. That satellite record is corroborated by the record of Antarctic and Arctic sea ice extent over the same period. There is no long term trend evident. Most recently, there has been a 1 million square kilometre increase over the long term mean. This is a five per cent increase.....

The peak US temperature was in 1936, at much the same time that Total Solar Irradiance peaked. If you have wondered why US temperatures are still lower than what they were 70 years ago, the fact that Total Solar Irradiance is lower than what it was 70 years ago might provide an explanation.....The peak of the Medieval Warm Period was 2ø warmer than today and the Little Ice Age 2ø colder at its worst. The total range is 4ø centigrade. The warming over the 20th century was 0.6 degrees by comparison. This recent warming has melted ice on some high passes in the Swiss Alps, uncovering artifacts from the Medieval Warm Period and the prior Roman Warm Period...2008 is the tenth anniversary of the recent peak on global temperature in 1998. The world has been cooling at 0.06 degrees per annum since then. My prediction is that this rate of cooling will accelerate to 0.2 degrees per annum following the month of solar minimum sometime in 2009.

Dr Hansen's statement that the maximum safe level of carbon dioxide in the atmosphere is 350 ppm begs the question of what the actual ideal level is. I have taken the 1,000 ppm figure from the level that commercial greenhouse operators prefer to run their greenhouses at. The ability to grow food is going to be the overriding concern next decade. Regarding that 1,000 ppm level, we will never get there.

Atmospheric carbon dioxide levels have been much higher in the geological past. But most of that carbon is now bound up in the Earth's sediments where we can't get to it. Half of the carbon dioxide we are producing now is being gobbled up by the oceans, in soils and in the Russian tundra. At best, we might get to about 600 ppm. What I have shown in this presentation is that carbon dioxide is largely irrelevant to the Earth's climate. The carbon dioxide that Mankind will put into the atmosphere over the next few hundred years will offset a couple of millenia of post-Holocene Optimum cooling before we plunge into the next ice age. There are no deleterious consequences of higher atmospheric carbon dioxide levels. Higher atmospheric carbon dioxide levels are wholly beneficial.
