Trees are not a complete answer. First of all, a lot of land is not suitable for trees. Second, trees can create their own “deserts” if they’re too close together. That condition can then create large, sudden die-offs and increased atmospheric CO2 due to rotting of massive amounts of trunks and limbs. And then, there’s the danger of huge fires when that fallen wood dries out.Climate scientists have been claiming for quite some time that “land usage” change (which would include desertification) it a factor in global warming; they would claim, however, that it is not the only factor. So there is nothing wrong with what you found, unless they insist desertification is the only factor contributing to climate change.
I don’t accept that GW has permanently stalled, if at all it has stalled, but goes up and down like a saw blade, with the saw blade angled upward. I guess we’ll see who’s right in 10 or 20 years. Considering that there may be more “pauses” (or increased deep ocean uptake of some of the warming) in the future as there has been in the past, I think it would take some 10 to 20 years for reasonable skeptics to be convinced AGW is happening.
However, you may be right that without desertification (and urban sprawl, which is sort of like desertification if people are replacing trees and plants with concrete) there may have been less warming, since desertification is a known factor.
However, since there are other warming factors, the warming probably would have still continued, only at a lesser amount.
That would be an interesting Q to put to climate scientists who are experts in that area – How much less would the warming have been without desertification? Or, what % of the warming can be attributed to desertification?
Many people do suggest that we do just what you suggested, plant more plants and trees to fight against AGW. In fact I have that in a pamphlet on GW I made some 20 years ago that includes planting trees, in addition to becoming energy/resource efficient/conservative and going on alt energy when feasible. We get a bunch of saplings and other plants from the local arboretum and nature parks and hand them out during Earth Day.
Apparently Alan Savory, at least, has abandoned CO2 as the cause of MMGW in favor of desertification. His situation is somewhat unique, though, because few really have the opportunity to experiment with it over significant tracts. It’s not enough to just say “I think it’s desertification because of my calculations of this and that”. To prove it out, one has to experiment. One can do that with desertification in a way one cannot with any other MMGW theory. But one’s access to land resources and the (name removed by moderator)uts has to be pretty significant.
Again, the lack of atmospheric warming in the last 17 or so years, combined with any MMGW theory one wants to choose, suggests that we may actually be in a cyclical cooling period which is slightly modified by MMGW.
Again, though, on the one hand we have MMGW theories based on scatterings of findings; some real and some flawed, and a lot of calculations and computer projections. Against that we have two things. First that the political methods of “mitigation” will absolutely cause known hardships in terms of job loss, unnecessary additions to the cost of living, and all the problems that come with reduced transportation. Second, nothing we do in the U.S. will significantly change CO2 concentrations in the atmosphere.
So, knowing it will be of no value to an outcome that’s really just theoretical, can we justify causing human hardship that we know for sure will happen?
It doesn’t seem so to me.
