NASA Discovers Mantle Plume That's Melting Antarctica From Below (newsweek.com)
schwit1 shares a report from Newsweek: Researchers at NASA have discovered a huge upwelling of hot rock under Marie Byrd Land, which lies between the Ross Ice Shelf and the Ross Sea, is creating vast lakes and rivers under the ice sheet. The presence of a huge mantle plume could explain why the region is so unstable today, and why it collapsed so quickly at the end of the last Ice Age, 11,000 years ago. Mantle plumes are thought to be part of the plumbing systems that brings hot material up from Earth's interior. Once it gets through the mantle, it spreads out under the crust, providing magma for volcanic eruptions. The area above a plume is known as a hotspot.
[I]n a study published in the Journal of Geophysical Research: Solid Earth, Seroussi and colleagues looked at one of the most well studied magma plumes on Earth -- the Yellowstone hotspot. The team developed a mantle plume model to look at how much geothermal heat would be needed to explain what is seen at Marie Byrd Land. They then used the Ice Sheet System Model (ISSM), which shows the physics of ice sheets, to look at the natural sources of heating and heat transport. This model enabled researchers to place "powerful constraint" on how much melt rate was allowable, meaning they could test out different scenarios of how much heat was being produced deep beneath the ice. Their findings showed that generally, the energy being generated by the mantle plume is no more than 150 milliwatts per square meter -- any more would result in too much melting. The heat generated under Yellowstone National Park, on average, is 200 milliwatts per square meter.

Alternate theory: Maybe PopeRatzo is also a political sock puppet account.
And the next question is whether this post about his dick makes it more likely that he's controlled by Don or Vlad.
tl;dr: PopeRatzo: Trollin' since forever.

You trolls always hate it when someone salts your game, but thankfully Slashdot has chosen to make your cowardice obvious with every comment. If you weren't a Russian sock puppet, you might be willing to log in and be counted.
Of course, you could just be a stupid dick. But we can't tell if you're just a stupid dick or if you're a paid Russian troll, since you won't log in.

Would that stand for Democratic People's Republic of Kalifornia?
I find it amusing that there are people from California that want to emphasize that California is NOT a state, it's a republic. This distinction is somehow important, I guess because California has a relatively unique concept in law that any citizen can bring a law to a ballot and have it become law by a vote. I'm not sure if this is what defines a republic, but it is certainly democratic. The state has certainly been run by people that call themselves (big 'D') Democrats for a while now.
Also amusing is how Californians take pride in that the state... sorry, republic, has the 7th largest economy in the world. This is nothing to be proud of since it was the 5th largest economy until Democrats and those public ballot initiatives shrunk the economic output. Just like the other DPRK I expect California to collapse within 5 or 10 years. That which cannot continue will not, and neither have an economy that can continue indefinitely.
