Permafrost / Reglaciation speculations (bbr)
« on: August 29, 2020, 03:54:15 PM »
I have been exploring the Himalayan anomaly this year. Initially it seemed to be a data error but clearly it is not. I believe that there has been a major increase in extant snowcover and depth as confirmed by the Canuck charts over the Himalayas this summer.
The crocodilians came about in the Arctic when Greenland was not extant. What if we are now seeing snow lines falling in the tropics / mid-low latitudes and rising at the Pole?
The Himalayan event has correlated with the Chinese floods. If this is some kind of state change or long term oscillation (i.e., one year it is Quebec, the next the Rockies, the next Himalayas, where the orographic anomalies anchor...?) the floods may continue. I would suggest that the "Quebec hypothesis" although wrong in its inception did touch on this idea of specific NHEM regions retaining coverage through summer.
What if this begins in a piecemeal fashion (i.e. one summer it is one region, and the region switches each summer), and then accelerates to where it is happening in 2 regions, 3 regions, then all regions?
It could also be possible that we have been "shifting" into a gear that puts the Himalayas at the forefront of the summertime cryosphere. But this shifting may do the same to other mountain ranges -- so there is also potentially a domino effect.
This is all speculation, clearly, but I would suggest that the next region to fall to a major increase in summertime snow coverage could, paradoxically and surprisingly, be the Southern Rockies. From a planetary wave perspective it is roughly equidistant on the other side vs the Himalayas.
If +SWE can begin accumulating at highest elevations in both the Rockies and Himalayas as it continues dwindling in the highest latitudes alongside ice volume, this would have PROFOUND impacts on global climate.
IMO this suggest summertime polar/Ferrell cells over the continents / fed by the SWE and albedo feedbacks, which deposit massive amounts of the worsening +OHC over the mountain ranges at their core (and cold areas at periphery).
ALSO: I think this new system sark is illuminating and I am hopefully further exploring does NOT necessarily mean Greenland melt will abate. In fact, I wonder if the lower snow lines go in the Himalayas and Rockies, the higher they get on Greenland? The mountaintop +SWE/extent anomalies will evacuate huge quantities of oceanic heat poleward, and if we get BOE and the Arctic also begins being unable to evacuate its stored heat each year, all of that excess is going to go into Greenland, potentially as glacial advance begins again atop the Rockies / Himalayas.
