New Focus

I'm now mostly a retired meteorologist but still love to watch Utah weather. I will continue to update the Utah weather cams and Utah weather links pages and occasionally post Utah weather related information. I'm spending more time enjoying Utah snow skiing, cycling, hiking, and water skiing.

Climate change

First of all climate change and the current episode of global warming is real and to think otherwise is a joke. The peak of the last ice age was about 20,000 years ago, the peak of the next ice age is expected to be around 80,000 years from now. The BIG question is what are the causes of climate change?

Human activity is surely to blame for some of the recent warming due to things like deforestation and urbanization. Many physicists (those with a true understanding of thermodynamics at the molecular level, not climatologist or meteorologists)  think the variation of solar radiation is the biggest factor in climate change but not the ONLY factor. The variation in the incoming soar radiation can mostly (not all) be explained by 
Sunspot activity and Milankovitch orbital cycles. Sunspot activity and Milankovitch orbital cycles have been well researched and discussed in the past but they don't completely explain climate change, other things like the amount of cosmic rays that reach the earths atmosphere from outside the solar system is another factor as are volcanic eruptions. 
I think most people understand how the amount of incoming solar radiation from the sun can increase and decrease temperatures and change climate but may not understand how cosmic rays that come from outside out solar system can influence temperature. Cosmic rays ionize the atmosphere which water droplets then condense on. A decrease in cosmic rays will lead to less ions for water droplets to condense on and a reduction in cloud cover, less clouds allow for more heating of the earth. A increase in cosmic rays will lead to more ions for water droplets to condense on and a increase in cloud cover, more clouds allow for more cooling of the earth. 

The only computer climate models that have come close to being able to go back in time and successfully forecast climate change have been mostly based on Milankovitch orbital cycles, Sunspot activity, cosmic rays, and volcanic activity NOT greenhouse gases like CO2.  CO2 and other greenhouse gases (of which water vapor is by far the most abundant) have long been a theory of climate change but physicists have proven otherwise.

  1. Hi Scott,

    I read your exchange of climate-change related posts in the SL Trib the other day. While I agree with you, on the Trib boards you are casting pearls before swine.
    My lady and I are amateur geology enthusiasts and as such, recognize the truth in what you say.
    The tribune boards are filled with people who think more laws and government spending will solve everything, on all issues.
    Thanks for speaking the truth, even though it makes you a lightning rod.
    We love your site.
    I'm in my off-season, but will be sure to donate when I'm back to work in a few weeks.
    Thanks

    1. Thanks for your kind words and support, truth with prevail in the end. Every day scientists are coming around to the fact that CO2 is not the cause of global warming and man has very little if any effect on climate. The likely cause of climate change is the various complicated earth/sun/solar system relationships that change the amount of the suns energy that reaches the earth.

    1. Yes there are those that don't agree and I encourage everyone to read both sides of the debate. My site links are for those that want to read about the less publicized articles that don't generate the hype and associated high ratings.

  3. Good list, thanks. I'm a meteorologist as well.
