Michael – “People who truly believe that the climate is changing catastrophically do not seem to be interested in global greening, it hurts their narrative.”
Both claims are false; I believe you are projecting.
I counter-claim that you have shown very little interest in the current ‘greening’.
Greening is talked about Michael, extensively if you look.
Yes there is greening happening and a large part of that is due to carbon fertilisation. The two countries that account for the majority of the area of greening equivalent to that of mainland USA are China and India. Both of those countries introduced specific measures to increase forests etc in an effort to help clean their air. Also some of that greening comes from increased crop planting in both those countries (nitrogen).Despite all the greening that has already happened CO2 in the atmosphere is still increasing and emissions are increasing still. The greening isn’t able to keep up with the amount of CO2 emitted.
Also, apparently plants acclimatise to the extra CO2 and the greening diminishes over time.

“Greening is talked about Michael, extensively if you look”well you would not know that from the BBC, unless I blinked and missed it.
Not sure what the latest position is, with regard to Global Greening, but a few years ago the figure was 21% extra Greening, I guess they meant the total the land had greened in the previous thirty years or so, that Sat. information has been gathered.
I believe they are now claiming that the World extra Greening, is equivalent to two continental U.S.A.s.
New study about to be undertaken
“The satellite that will ‘weigh’ world’s 1.5 trillion trees”
https://www.bbc.co.uk/news/articles/crldwjj6d6noSorry if I have been less than friendly, I have earache and sinusitis, it is painful, not been getting enough sleep, just started antibiotics, today.
michaelET, thankyou for those two BBC articles.
The most recent one was six years ago.
Perhaps the BBC should gird its loins and do a programme
on Global Greening?Michael, you are correct, they are from a while ago. So also is the NASA study that presented the analysis of the data from the two satellites upon which all this greening topic is based.
My appraisal of your argument is this:
CO2 levels in the atmosphere have increased and some of that is because of human activity. However, that increase in carbon dioxide (or green house gases) drives a feedback mechanism of carbon fertilisation which will tend to reduce Carbon dioxide levels (and increase greening as a positive consequence). Thus as a result we need not worry about climate change, can carry on emitting CO2 for economic, national interest, employment reasons because the planet’s feedback mechanisms will sort it out for us. No need for unnecessary concern.I’ll point to just one counter to that argument. There are a number of others which we may get to yet. CO2 atmospheric levels are still rising despite the greening of an area twice that of the continental US. Dose that fact alone note give you pause for thought?

ET,
I think the Americans have just been measuring green leaf coverage – not mass of tree wood.
The new scan will measure tree wood mass.
With flowering trees, they have an awful lot of leaf coverage, each year that abundance of leaf falls to the earth, most of that leaf will form new top soil. if there is a greater mass of top soil, then there will be an increasing greater abundance of short cycle Carbon held in the soil.
This greater abundance of Carbon will retain a greater quantity of water, the slow release of that water to the flowering trees, could increase their growing days, meaning each annual tree ring will be wider, meaning more mass of Carbon in the short Carbon cycle held in those trees.
So, extra CO2 should mean more Carbon stored in the soils and more Carbon stored in the trees.
I expect that extra Carbon dioxide in the Atmosphere will have the greatest effect ( on land) in the great deciduous forests of the tropics and the temperate zones.ET,
yes, I do find it a bit astonishing, that it is being recorded as continually increasing.
Perhaps you need the greening first, then more gradually the trees bulk up?C’mon Michael, I asked you a very specific question. Despite greening of an area equivalent to two times the area of the continental United States atmospheric CO2 levels are still rising. Fact vs fact. It surely must cause concern for the sheer magnitude of emissions of CO2?
Please don’t dissemble and deflect. Just take on that specific point before you expound on anything else.I have just done some calculations and it seems the mass of trees on Earth is 17 times greater that the Carbon we annually pump into the air.
So, it seems I am mistaken and it would seem there will not be a fix, this way.
