WebAug 25, 2015 · The massive Greenland ice sheet is shedding about 300 gigatons of ice a year into the ocean, making it the single largest source of sea level rise from melting ice. Credit: NASA/Saskia Madlener. Sea level rise is a natural consequence of the warming of our planet. We know this from basic physics. When water heats up, it expands.

Ice at the glacier base may melt, depositing Glaciers can also move sediment from one place to another when it flows over sediment …
According to a 2009 study, the continent-wide average surface temperature trend of Antarctica is positive and significant at >0.05 °C/decade since 1957. West Antarctica has warmed by more than 0.1 °C/decade in the last 50 years, and this warming is strongest in winter and spring. Although this is partly offset by fall cooling in East Antarctica, this effect is restricted to the 1980s and 1990s. WebApr 13, 2012 · A. Ben Holt: Icebergs form from the natural calving of glaciers and Earth's great ice sheets, which extend into the ocean. These ice extensions, called tongues and shelves, lose strength as they extend further from their attachments to land, eventually breaking off in a process called 'calving' to form icebergs. Q. How do icebergs move?

Compression and geothermal energy sometimes cause the bottom of an ice sheet to be slightly warmer than the ice above it. The bottom of the ice sheet melts, causing the ice above it to move at a faster rate than the rest of the ice sheet.
