| 1) Turns out there are a bunch of volcanoes, 91, underneath the west Antarctic ice sheet that we previously didn't know about. In fact: (Excerpts are placed between square brackets.) ["We were amazed," Bingham said. "We had not expected to find anything like that number. We have almost trebled the number of volcanoes known to exist in west Antarctica. We also suspect there are even more on the bed of the sea that lies under the Ross ice shelf, so that I think it is very likely this region will turn out to be the densest region of volcanoes in the world, greater even than east Africa, where mounts Nyiragongo, Kilimanjaro, Longonot and all the other active volcanoes are concentrated."] 2) Furthermore, eruptions would cause the ice sheet to melt: [“Anything that causes the melting of ice – which an eruption certainly would – is likely to speed up the flow of ice into the sea.] 3) They could already be erupting and causing the ice to melt: [“We just don’t know about how active these volcanoes have been in the past,” Bingham said.] 4) Also, consider this quote: [If one erupts, it could further destabilise some of the region’s ice sheets, which have already been affected by global warming.] I followed the link. The headline is: [Although fracturing and surface melting on the Larsen C ice shelf might sound like indicators of climate change, these processes are natural] The article links to a source, another article in the same paper, that actually contradicts the claim it is making. Another quote from the article: [So, while ice fracturing and surface melting may sound like signs of climate change in action in Antarctica, they are really part of the background against which we must look for real change.] |
