Progressive bottom melting and break-up of West Antarctica’s seafloor hugging Larsen Ice Shelf is fueled by heat and heated fluid flow from numerous very active geological features, and not climate change.
This ice shelf break-up process has been the focus of an absolute worldwide media frenzy contending man-made atmospheric global warming is at work in the northwest peninsula of Antarctica. As evidence, media articles typically include tightly edited close-up photos of cracks forming on the surface of the Larsen Ice Shelf (Figure 2) accompanied by text laced with global warming alarmist catch phrases. This “advertising / marketing” approach does in fact produce beautiful looking and expertly written articles. However, they lack subsidence, specifically a distinct absence of actual scientific data and observations supporting the purported strong connection to manmade atmospheric global warming.
Working level scientists familiar with, or actually performing research on, the Larsen Ice Shelf utilize an entirely different approach when speaking about or writing about what is fueling this glacial ice break-up. They ascribe the break-up to poorly understood undefined natural forces (see quote below). Unfortunately, comments by these scientists are often buried deep in media articles and never seem to match the alarmist tone of the article’s headline.
“Scientists have been monitoring the rift on the ice shelf for decades. Researchers told NBC News that the calving event was “part of the natural evolution of the ice shelf,” but added there could be a link to changing climate, though they had no direct evidence of it.” (see here)
