Many scientists believe climate change is caused by changes of the sun, oceans, and clouds.
That makes much more sense than claiming manmade CO2 is the climate controller, considering the minimal evidence the CO2 theory is true.
The claim that CO2 controls the climate is an unproven theory with much evidence refuting it.
In 4.5 billion years, Earth has only had one brief period, from 1975 to 2000, when manmade CO2 and average temperature were both positively correlated.
And mere positive correlation does not prove the CO2 rise caused the temperature rise.
The CO2 theory is wrong even when looking at only the past 75 years, when man made CO2 increased every year:
-- We had negative correlation of CO2 and temperature from 1940 to 1975, positive correlation from 1975 to 2000, and near zero correlation from 2000 through 2015.
Climate history includes only one CO2-average temperature relationship:
-- Warming from natural causes gradually warms the oceans, and then the oceans release some of their dissolved CO2 into the air with a lag of hundreds of years !
The majority of the Earth’s surface is some form of water.
CO2 would increase in the atmosphere as huge volumes of water, such as the oceans, increased in temperature.
H2O, the most important greenhouse gas by far, would increase in the atmosphere if just the surface of bodies of water warmed.
The manmade global warming (AGW) theory is that adding CO2 to the air causes an increase in its radiant thermal insulation properties.
The effect is small because CO2 is only about .04% of the atmosphere.
H2O, which averages around 2% of the air, is the primary greenhouse gas.
The AGW theory is that CO2 causes a small amount of warming, which then causes more H2O to enter the air, which greatly amplifies (positive feedback) the radiant thermal insulation properties.
In plain English that means warming causes more warming, which causes more warming, and the eventual result is runaway warming.
AGW plus positive H2O feedback = Catastrophic AGW (CAGW), or runaway warming.
Runaway warming is a science fiction fantasy created by left wing politicians to scare people, and control them.
Our planet has had CO2 levels up to twenty times higher than today with no runaway warming.
H2O is a greenhouse gas that warms our planet, and is a far more important greenhouse gas than CO2.
But H2O also cools the atmosphere by transferring surface heat energy to where clouds form.
More H2O in the air means more clouds.
Clouds reflect some incoming solar radiation, reducing the daytime temperature.
Clouds also radiate heat to space more efficiently than a clear atmosphere, cooling the Earth faster.
H2O and clouds provide negative feedback to counteract warming, whether the warming is natural or man made.
The proof that H2O provides negative feedback to any warming is that Earth’s climate has been stable enough for life to evolve in the past 500 million years.
