Antarctica lost 3 trillion tonnes of ice in blink of an eye

Antarctica lost 3 trillion tonnes of ice in blink of an eye
"We have long suspected that changes in Earth’s climate will affect the polar ice sheets. Thanks to the satellites our space agencies have launched, we can now track their ice losses and global sea level contribution with confidence,"....

West Antarctica is currently bearing the brunt of this loss, as its glacial ice shelves have been melted from below by warming deep ocean water. According to the study, the rate of loss in that part of the content has increased from 53 billion tonnes per year in the 1990s, up to the current rate of 159 billion tonnes per year. The Antarctic Peninsula - the portion of the continent that reaches out for the southern tip of South America - has seen an increase from an average of 7 billion tonnes per year, up to 33 billion tonnes per year in that same time period.


Of course, this means nothing to idiot global heating deniers.

Subura: any good notion of whether the ice melt at either Antarctica or Greenland will actually just slowly melt, OR.... WILL THERE BE a giant collapse of some ice field into the ocean raising level by meters overnight? Is it only a risk....or an undeniable consequence and we just don't know the time when it will occur?

Er, 25 years. Not exactly what I'd call "the blink of an eye", unless you're speaking in geological or astronomical terms.

3 trillion tonnes is not so big, either. The oceans contain about a quintillion tonnes of water.

So you are talking of an increase in the mass of water in the oceans of 1 part in 300,000.

'
It should be obvious to anyone with half a brain that what is important is the increase in the rate of melting over the past 25 years.

I can agree with that sentiment, but I reserve the right to pedantry should the mood, opportunity, and keyboard exist with which to express it. :beee:

(In other words, sometimes I'm picky about phrasing.)
