A recent study, conducted by scientists at Lawrence Livermore National Laboratory and published in the journal Nature Communications, discovered a link between diminishing Arctic sea ice and the buildup of high ridges of atmospheric pressure over the North Pacific. (climaterealityproject.org)
Higher ridge elevation indicates a hotter mantle — as in Iceland, above, which also appears to sit atop a mantle plume, a vertical jet of hot rock originating from deep in the Earth. (sciencedaily.com)
The lakes are surrounded by high ridges, hundreds of meters high in some places. (sciencedaily.com)
