There is an article on geo-engineering at the Greenland and Antarctic ice shelves to stop their moving and increase glaciation. I contacted the principle investigator about his approach vs forcing more of the melting. This article serms to support the hypothesis that humans could realustically try some geo engineering projects that might buy our species some time. In the past, a Canadian pre-historic lake, Agassiz was believed to have been breached suddenly, dumping more of this fresh water into the North Atlantic. It shut off the North Atlantic conveyor stopping circulation of warm gulf wsters, which started the last mini ice age. I proposed we do the same with Greenland’s ice, melting it quickly to stop the brine cycle in the N Atlantic. This should produce another mini ice age that might buy us enough time to outlaw hydrocarbon combustion exhaust and convert all energy and transport systems to renewable power.
If not, as he says, we just raised ocean levels by a meter or more. Both this rising sea level or ice age would be hard. But which one allows us to get our shit together? We come out of any ice age with more CO2 and methane than ever before, and more people, but we need to get control of our spaceship!
We got no other place we can live, and we’ve poisoned our ship to the point where we’re getting cancer from it at an alarmingly increasing rate!
My perspective is if the system shows a tendency towards that behavior now, i.e. the shutting down of the thermal converor, then Force it! Before Greenland all slowly melts, and all we get is down-side: no forced cooling (is an ice age just as hard or harder than 128°F in LA for 45 days straight? Or 132 in Vegas and Phoenix) No glacier source to try this proven method (Ref Wallace Broeker Columbia University) after its gone, sea level rise anyway. Plus ultimately we risk: +5°C which releases all permafrost methane and poof: we instanly become cooked like Venus.
Comparing the scale of projects, melting Greenland vs. Making concrete structures underwater of massive proportions, the former offers potentially greater hope. A UN project uniting mankind’s Nuclear arsenal of ships as a means to accelerate creation of a freshwater lake would be a low CO2 way to get there. Portable heaters on steroids for sure! Imagine, they might actually help humanity. Make a big central lake of meltwater in Greenland then dump it into the N Atlantic to shut off already diminished circulation vs construction of huge cement factories (burning methane and pumping tons of CO2 for every ton of cement needed) making cement for concrete to pour Hoover dam sized blocks on the bottom of the treacherous North Sea that would hopefully grab the bottom of a glacier and slow it down.
Compared to the Greenland glacier sizes, the Hoover dam is far too tiny to hold up the glacier. Several would be needed. Compared to the size and strength of a glacier (they carved out the great lakes) the Hoover dam is a gnat fart in a hurricane. We must do even more as passengers on this same Starship Earth before we foul up our life support systems and kill everybody!
