Read here. As the temperature chart on the left reveals (click on image to enlarge), sea surface temperatures have generally been declining around the Pine Island Glacier over the last 30 years. This evidence is in contrast to global warming alarmista claims that Antarctic glaciers have been shrinking due to CO2-induced warming. Now, real-working scientists have discovered a different cause of the shrinking glacier that has nothing to do with human CO2 emissions.
“The discovery of the ridge has raised new questions about whether the current loss of ice from Pine Island Glacier is caused by recent climate change or is a continuation of a longer-term process that began when the glacier disconnected from the ridge.....“We do not know what kick-started the initial retreat from the ridge, but we do know that it started some time prior to 1970. Since detailed observations of Pine Island Glacier only began in the 1990s, we now need to use other techniques such as ice core analysis and computer modelling to look much further into the glacier’s history in order to understand if what we see now is part of a long term trend of ice sheet contraction."
