Tipping point

Greenland’s enormous ice sheet is melting at such an accelerated rate that it may have reached a “tipping point,” and could become a major factor in sea-level rise around the world within two decades, scientists said in a study published on Monday.

Just a week ago, a separate study of ice loss in Antarctica found that the continent is contributing more to rising sea levels than previously thought.

Another new analysis suggested that the oceans are warming far faster than earlier estimates. Warming oceans are currently the leading cause of sea-level rise, since water expands as it warms.

(this is not the Keeling analysis criticized by Lewis and corrected for a greater margin of error. It is a newer, independent study.)
While 93% of the heat generated by global warming is absorbed by the oceans, preventing a much faster rise of global temperatures, this also poses a problem: it will take at least 15 times as long to cool down again once the atmosphere has been restored to normal levels. In that light we may already be way past the tipping point; the current ocean temperatures are not going to drop much in the next couple of hundreds of years, so there's no stopping the total collapse of basically all ice sheets and glaciers.
Lies of course?
