Average global temperatures did not rise for 12 years, 2002 to 2014. In the next several years, two big El Ninos, natural phenomena, bumped global temperatures up. But since then, the global temperatures have declined and seem to be plateauing as they did in the 2002 to 2014 period. Then as now, CO2 concentration is continuing to rise without commensurate rise in global temperatures.
Also, there is a new study that says man made aerosols have decreased significantly since 2000. Because aerosols are believed to reflect the sun’s rays, preventing them in reaching the Earth’s surface, the reduction in aerosols should result in increasing global temperatures.
One could conclude that increased CO2 is not very effective in raising temperatures and further some thing else is causing cooling despite the reduction of aerosols.

Hi CB, Good to see you are still functioning. I am heathy but walk with a stick because I have balance problems. I am making my comments at (PricnipliaScientific.com). Or something like that. And I my memory is not getting any better. But I still believe I can see what is not commonly being seen. Today I going to question what the new telescope is seeing relative to the images that NASA is sharing of Jupiter. Have a good day, Jerry

Good to hear from you, Jerry. I do Pricniplia Scientific.com about once a week. So I catch some of you comment. You hold your own.
I am in pretty good shape for my age. Unfortunately, my wife died in December last year. And I slowed down on about everything but have decided to get back in the swing of things.
Hang in there.
Chuck
