In an exclusive interview with Mother Channel, Professor Peter Wadhams leading Arctic scientist and Prof. of Ocean Physics at Cambridge University, talks on catastrophic outcomes in terms of Retreating and Thinning Sea Ice, Methane in Oceans and on Land, Carbon Emissions, Food shortages, Resources and global Refugee crisis at COP 22, Marrakech.
In the period since COP 21, I have returned to the Arctic twice since then, my latest field trip being to measure waves in ice at the Barents Sea, in a region east of Svalbard, a Norwegian archipelago between mainland Norway and the North Pole, where normally the winter ice would be about 1.5m thick, but instead was found to be only 40cm thick, very much thinner, and the actual ice sheet was bending under the wave motion, this being one of the regions where the winter ice is retreating and thinning and it should have been at its maximum thickness. Also of note, in the autumn of 2016 we did a field trip into the southern most part of the Beaufort Sea (Canada’s western Arctic stretches across the northern coasts of the Northwest Territories and Yukon, and into Alaska), when the ice is advancing (winter freeze up season), however, due to there being so much open water around the edge of the Arctic ice cover, the ice was not advancing, due to accumulated heated water by solar radiation (see : http://www.srmgi.org/what-is-srm/) and storm waves bringing up heat from ocean depths causing ice retreat. The end result was a much slower advance of the ice than it had been in previous years, with the ice extent in Arctic being the lowest in the 2015-2016 winter. These long term trends of retreat and thinning are being observed everywhere and we see nothing to stop that trend continuing until all the ice in regions like these disappears totally!
In terms of talking ‘methane’, there’s a difference between halting it and removing it! There have been big ideas concerning methane removal before being emitted naturally to the atmosphere, mostly oil drilling techniques in the form of shallow oil drilling, which would require a large network of wells in shallow water located mainly in the territorial waters of Russia, i.e. East Siberian Sea, Barents Sea, Kara Sea and Laptop Sea, with permissions being required from Russia to carry out any type of drilling process, which is highly unlikely considering Russia’s stand and lack of interest in Climate Change.
The only feasible method with any possibility of working, a geo-engineering technique that has been identified in recent years, called ‘Marine Cloud Brightening’, see : https://www.sciencedaily.com/releases/2014/12/141215203029.htm, where low lying clouds are injected with water vapour (particles) which makes them much brighter causing more radiation to be reflected, in turn causing a targeted cooling effect on the climate. Climate modelling studies have shown that there are three regions in the Northern hemisphere, where if this technique were applied in a focused and simultaneous manner, the effect will zero in on the Arctic thereby cooling the region in preference to other parts of the world, causing the Ice age to advance, once again.
Methane is responsible for approximately a quarter of global warming at the moment, an important factor, however, the big methane problem would be an Arctic emission!
In global terms, everything is changing exponentially, and in a finite world, you cannot have everything growing or changing exponentially indefinitely, everything would come to a grinding halt. At the moment, all the elements are in place for a catastrophic outcome, because we have rapid population growth beyond the capacity of the earth to support it, a threat to food supplies from climate change which in turn is threatening the existing level of food production, let alone increased production to handle increased populations (Population – Food Crisis), including a resource crisis in terms of oil reserves, lithium, etc which will not last indefinitely.
With sea levels rising inexorably, which will continue rising, partly in response to previous warming periods, the current risings are attributed mainly from melting of the ice from the glaciers, causing many more floods in low lying sensitive areas, like Bangladesh and China, but also disasters to low-lying cities, e.g. Miami, having a huge economic ‘knock-on’ effect because its been calculated that that in itself could bring the “Economy of the West to its Knees”, due to loss of vast wealth tied up in coastal real estate, which would plummet to Zero!
If one were to sum up all the negative impacts, which are getting worse at an increased rate, there is not anything compensating in the way of stabilizing effects – everything is destabilizing in an accelerated manner.
