The climate is changing. It is always changing. Remember when ice covered most of the northern hemisphere a few thousand years ago? Remember the Little Ice Age
**broken link removed** Remember when Europe could grow grapes much further north than they can now?
What causes Earth temperature changes? When I sit in my car on a sunny day with the windows closed, the car becomes very warm. Since I exhale CO2, it could be said that CO2 is the cause. But the car still becomes warm even when I am not inside. I notice that the temperature does not rise above the ambient temperature when the sun roof is rolled back. I conclude that the cause of temperature rise in my car and a greenhouse is lack of convection. Besides, greenhouse plants consume CO2.
CO2 is a thermal insulating gas. The slang term for this property is "greenhouse gas". The percentage of CO2 in the Earth's atmosphere is 0.04%. The percentage of water vapor in the atmosphere varies from zero % in the Gobi Desert to 4% over the warm tropical oceans. Using an average of 2%, we can assume that the water vapor is 40 to 60 times more prevalent than CO2. The kicker here is that water vapor is a better thermal insulator than CO2, and is far more prevalent. In other words, CO2 is an insignificant factor compared to water vapor. Good luck to those who want to reduce water vapor in the air. CO2 is an essential plant requirement, not an atmospheric pollutant
So what is causing atmosphere temperature changes? The Sun spews out an enormous amount of charged particles called the solar wind. This can observed as Northern or Southern Lights. The cosmos puts out high energy particles call cosmic rays. They can be observed in a cloud chamber
https://en.wikipedia.org/wiki/Cloud_chamber . The cosmic rays help the water vapor condense into clouds, which in turn, shield the earth from the thermal effects of the sun. The solar wind pushes away the cosmic rays, thereby causing fewer clouds to form. The solar wind intensity is cyclic, and so are the thermal effects. The effects are delayed by thermal equilibrium. So, global warming does not depend on CO2, but instead on the solar cycle

So why is there a controversy? The reason is $$$. Climate change has put a lot of dinners on the table for a lot of people. Think of the government grants, endowed chairs at the colleges and universities, and other financial endowments. But, perhaps more, think of the bureaucracy and rule over people's lives that government likes to do. So, look at the facts and figures and determine for yourself what the situation is. What a shame we are wasting so many financial resources.
