Is Man made Global Warming Real? • “The ice shelves in the southern part of the Antarctic Peninsula appear to be disappearing because of climate change, according to a new report from the U.S. Geological Survey and the British Antarctic Survey.” – USA Today • “Antarctica is warming, but not melting anything like as much as expected. In fact, during the continent's summer this time last year, there was less melting than at any time in the 30 years that we have had reliable satellite measurements of the region.” – ABC news • Mt. Erebus is one of a few constantly active volcanoes in the world. • “Emission rates of SO2, HCl, and HF from the active volcano Mount Erebus, Antarctica, increased between 1986 and 1991;” – Journal of Geophysical Research.
