What changes albedo over time? What is the residence time of water vapor in the air? How can water vapor drive long term climate change?
Look it up. Recent evidence is showing it to be one of the major natural factors that caused the 1978-1998 temp increase. Again, look it up.
Clouds happen to be what computer models cannot model. Computer modelers have to manually put in an x amount to then run simulations (I.e. insert a fixed number from their best educated estimation). Recent excuses for the "failed" Global Warming computer models is the cloud parameter. Again, look it up.
Why? A 2% change in earth's cloud cover over a 1 year period will result in a 1°F change in earth global temperature!!! For 2% more clouds a 1% decrease in global temperature; a 2% decrease in cloud cover and a 1% increase in global temperature!!! Again, look it up.
The natural factors must first be understood and the natural baseline established in what weather and climate we will have before anyone can come to understand what effects CO2 has on earths temperature. The baseline set by natural factors must be established first.
The natural factors baseline has never been established in climatology, however this is the pivot in knowing how much influence each natural or manmade climate variable has on Global Warming or Cooling.
The IPCC, in particular, through promoting bad science has made people think CO2 over powers all natural factors and is the control knob controlling earths temperature. They have promoted that if society raises atmospheric CO2 content then the earth temperature will go up proportional to CO2 content; if society brings atmospheric CO2 levels down then the earths global temperatures will go down. The IPCC and other organizations promote CO2 is THE control knob to control earths temperature.
That has been one of the misleading "science is settled" over promotions for an agenda.
I've been like everyone else and have had to learn and discern to find out what is going on.
