Some of you demand evidence but do not accept it when it is presented to you: disappearing sea ice, melting permafrost, retreating glaciers, desertification, crop failures, food shortages, water scarcity. These are all consequences of ongoing AGW…

No, they are not.

They may be consequences of a changing climate or poor land management, but they are not necessarily consequences of ongoing AGW, especially AGW caused by anthropogenic CO2 emissions which is the main point of discussion.

Have we been warming since the end of the LIA” – mostly yes, lately not so much, but it is likely that we will begin warming again (unless the folks suggesting we are about to begin a cooling phase are right).

Has the atmospheric CO2 level been rising also since shortly after the end of the LIA? – again, yes.

However, while the rate of the atmospheric CO2 rise has been fairly consistent, the cooling and warming has not, although it has been somewhat cyclic as it moves in the warming direction.

Ask yourself – how much CO2 is put into the atmosphere each year? How much is put there by anthropogenic CO2 emissions? What percentage then is the anthropogenic contribution? Why then, of the about 2 ppm of CO2 being added to the atmosphere each year, isn’t the anthropogenic contribution that same percentage? Wouldn’t that be just as logical as saying the entire 2 ppm is anthropogenic?

Also, I’ve reminded folks a few times that

-Arctic Ice disappearing
-Glaciers retreating
-Coral reef bleaching
-Mt Kilimanjaro losing snow
-Polar bears doing anything anywhere
-Some creature or plant facing extinction
-A change in cyclones/hurricanes/typhoons
-Droughts
-Floods
-Dry rivers
-Computer models or simulations
-A “consensus”
-Al Gore’s movie
-Etc. causing etc. by etc. reported by etc., etc.

are not proof of CAGW by CO2.
