Antarctic Volcanoes vs Climate Change
Volcanoes are melting glaciers in West Antarctic but never mind that ... because "Global Warming"!
Or ... read the rest of this selective reporting about science and selective interpretation of research:
Newly-discovered active volcano underneath ice in West Antarctica
A newly-discovered active volcano could erupt underneath Antarctica, melting the ice from below and compounding the effects of global warming, according to scientists.
Researchers discovered the volcano underneath the ice after setting up devices to measure tectonic activity across Marie Byrd Land in the west of the continent.
Scientists had intended to use the seismograph machines to help in their efforts to weight the ice sheet - only to find that a volcano was in fact forming underneath the ice.
Volcanic activity was discovered around 30 miles from Antarctica's highest volcano, Mount Sidley, and although an eruption would be unlikely to breach the ice - the accompanying heat could have an effect on the landscape.
Even a sub-glacial eruption would still be able to melt ice, creating huge amounts of water which could flow beneath the ice and towards the sea - hastening the flow of the overlying ice and potentially speed up the rate of ice sheet loss.
'Numerous volcanoes exist in Marie Byrd Land, a highland region of West Antarctica,' said Amanda Lough, of Washington University in St Louis in the team's paper on the subject, published in the Nature Geoscience journal.
'High heat flow through the crust in this region may influence the stability of the West Antarctic Ice Sheet.'
The Climate Alarmism Is Science Study
The huge West Antarctic ice sheet is starting a glacially slow collapse in an unstoppable way, two new studies show. Alarmed scientists say that means even more sea level rise than they figured.
The worrisome outcomes won't be seen soon. Scientists are talking hundreds of years, but over that time the melt that has started could eventually add 4 to 12 feet to current sea levels.
A NASA study looking at 40 years of ground, airplane and satellite data of what researchers call "the weak underbelly of West Antarctica" shows the melt is happening faster than scientists had predicted, crossing a critical threshold that has begun a domino-like process.
"It does seem to be happening quickly," said University of Washington glaciologist Ian Joughin, lead author of one study. "We really are witnessing the beginning stages."
It's likely because of man-made global warming and the ozone hole which have changed the Antarctic winds and warmed the water that eats away at the feet of the ice, researchers said at a NASA news conference Monday.
"The system is in sort of a chain reaction that is unstoppable," said NASA glaciologist Eric Rignot, chief author of the NASA study in the journal Geophysical Research Letters. "Every process in this reaction is feeding the next one."
