The Sun, Global Warming, and an Ice Age
Being a person familiar with radios, and using them frequently, I know a little about sun spots. I know they effect the earth in a tremendous number of ways, one of those ways is radio interference, but another is global temperature (many others too). The temperature one is the important one here, because the amount of energy we receive from the sun is the number one factor in global temperature, not whether or not there is 2% more CO2 in the atmosphere or 2% less.
Should the sun go into a state of relative dormancy, we could find global temps drop by 1-2 degrees C (from what I’ve read) or more. Of course we have, allegedly, caused an increase of .7 degrees C all by ourselves. This is, of course, being hailed as the end of the world or something near to it.
Moving closer to my particular area of formal study, we know that about 500 years ago we had a period that lasted nearly 70 years where global temps dropped, people starved and the ice caps extended. They call it ‘the little ice age’. We also know that this was a period of relative solar dormancy.
There are strong indications that after the solar activity peak in 2013 or thereabouts, the sun will go on vacation a bit, and this could have problems.
While global warming, if it isn’t all just a statistical or grant (money) grabbing issue, could lead to longer growing seasons and higher production, while at the same time having some negative effects such as sea level rise. A period of solar dormancy would be much, much worse. There are almost no positives to it. Growing seasons shrink, ice caps MAY extend, sea level would drop, colder temps in areas where people lack the buildings and clothing and other resources to deal with it, would be a disaster, not of our making but of a natural cycle.
The loss of life would be much higher, the level of extinction would be much higher, and there isn’t a damned thing we can do about it.
Is it ‘settled science’? No of course not, there isn’t any such thing. We were not standing around with our current knowledge and technology to see what happened the last time the sun took a nap, much like we were not there studying times when global CO2 levels were what they are today. With the amount of money flying around in the global warming community, I maintain that their judgment is compromised and it’s likely not as bad as we hear, if extant at all.
The facts are clear in one respect on both things. Humans have flourished during warmer global periods and died off in droves during colder ones. Lets hope we end up with global warming instead of a long period of global cooling.
