Scientists from the Earth Institute at Columbia University, reportedly discovered a link between subglacial lakes in Antarctica and flowing of the ice streams into the ocean. As I often try to say, “climate change” is a rather complex issue with so many parameters involved; not a simple and plain phenomenon that you could explain with “global warming”, “global heating” or “greenhouse gases” cliches. Below is an excerpt from the news story, published on Eurekalert:

Geophysicists Robin Bell and Michael Studinger from the Lamont-Doherty Earth Observatory, a part of The Earth Institute at Columbia University, led a team that discovered four large, subglaical lakes that for the first time the link these water bodies locked beneath miles of ice, to fast flowing ice streams in Antarctica. Together with colleagues from NASA, the University of New Hampshire and the University of Washington, the scientists found that, in four separate cases, lakes appear to contribute to the formation of ice streams. Their work appears in the February 22 issue of the journal Nature.
Moreover, their work suggests that subglacial lakes could play a role in and sea level rise as well as regional and global climate change. Meltwater at the base of ice streams increases the flow of ice to the oceans, which could, in turn, contribute to higher sea levels worldwide.
