I simply don't need all that analysis to interpret that the climate variances are related to Sunspot Minimums and Maximums. That has been show empirically over the past 200 years.
Cause? It is the Sun Stupid, not Man.
Thanks. I am a fossil guy too. As you probably know there are over 200 factors in the computer model Global Warming of the “Experts.”
How in the world can an idea be tested with 200 variables?
“
So they press on knowing that their idea is safe from statistical “testing.” However, their idea has no know cause and effect. Hence, Science rejects the Global Warming idea as defined without any known cause and effect.
True, the Sun has an effect on the temperature of the air, as do volcanoes and lack of water vapor. Water vapor is our major Greenhouse Gas with 2.5% of air volume, and CO2 is one of the least 0.0385 %. In parts per million that is 25,000 and 385, respectively.
All living matter has CHON in them, that is Carbon, Hydrogen, Oxygen, and Nitrogen. All of these elements are essential to life. All in non-toxic concentrations are environmentally friendly.
The Carbon in CO2 is the primary source for carbon in the process of photosynthesis. The past has had many times when the concentration of CO2 was greater than it is now.
In Nature, cycles are common. We are in a warming cycle now ( 1 +/- degree F/100 years ). But it was warmer in The Medieval Warm than it is today, and much warmer 5,000 years ago.
Keep up the good work, and ping me when you find a cause and effect involving CO2 and air temperature.
