I saw the following post in another thread and wanted to highlight it. What are your thoughts on the arguments below?
I've followed global warming research/commentary for about 15 years now. One of AGW's major theories will be proven or disproven in the next two months. That premise is that the rise in atmospheric CO2 levels is directly related to the rise in manmade CO2 emissions. I personally believe that this is true.
CO2 levels are monitored at Mauna Loa and hit new highs every year in May/June. However, global CO2 emissions have dropped significantly worldwide due to Covid 19 and especially in China, which is upwind from Mauna Loa.
Here's why this is important.
If CO2 concentrations continue to rise at the same rate as last year, this would invalidate AGW theory that manmade emissions are causing the rise in CO2. It would also invalidate the premise that the Green New Deal will make any difference.
If CO2 concentrations actually decline, it would invalidate the premise that CO2 emissions remain in the atmosphere for decades. This would negate the necessity for radical action now. We could simply wait until 2030 or so when better technology exists to reduce CO2 levels.
OTOH, if the rate of increase slows or pauses, it would tend to validate *part* of AGW theory. That is, that atmospheric CO2 rise is directly attributable to manmade CO2 emissions. However, it wouldn't prove that the models predicting future changes are accurate.
