"Leading Antarctic experts offer two possible views of " Topic

….continent's future

"The next 10 years will be critical for the future of Antarctica, and choices made will have long-lasting consequences, says an international group of award-winning Antarctic research scientists in a paper released today. It lays out two different plausible future scenarios for the continent and its Southern Ocean over the next 50 years.

Writing in Nature, the authors are all winners of the Tinker-Muse Prize for Science and Policy in Antarctica and experts in such disciplines as biology, oceanography, glaciology, geophysics, climate science and policy.

Recent work by Rob DeConto, the 2016 winner of the Tinker prize and professor of geosciences at the University of Massachusetts Amherst, includes findings in a 2016 paper also in Nature that highlights the potential for Antarctica to contribute much more sea level rise to the world's oceans than previously considered…."

It will either melt or it won't.

I betting on that it won't.

So it's…

Antarctica and the Southern Ocean would see dramatic loss of major ice shelves by 2070 leading to increased loss of grounded ice from the Antarctic Ice Sheet and an acceleration in global sea level rise. Further, "unrestricted growth in human use" will have degraded the environment and introduced invasive pests.

…unless global warming is stopped.

WooHoo! If I live long enough maybe I will finally have beachfront property.

And of course any increased human use is a degradation of the environment.

Surprised they broke out humans from the other invasive pests.

It will either melt or it won't.

I betting on that it won't.

But of course that is not what the article said. The comment is:

"Antarctica and the Southern Ocean would see dramatic loss of major ice shelves by 2070 leading to increased loss of grounded ice from the Antarctic Ice Sheet and an acceleration in global sea level rise."

So what are you betting on?

The Antarctic Ice Shelves are melting right now.

But, the Artic ones are increasing, so we have a simple shift from South to North.

damn yankees.

Yeah, I think we should do what scientists were begging us to do last time they got us all worked up about the climate … paint the glaciers black or gray.

You get that from ClimateDepot? Lol!

Sorry, all the Arctic ice shelves are melting. In fact the melt from July was the fastest so far.

Now, some parts of the Ross Ice Shelf gained ice during last winter. This was reported at the beginning of the year. This is confusing as other parts of Antarctica are still melting. Clearly other poorly understood mechanisms are at play.

But your suggestion that one pole is melting while another is freezing is not supported by the evidence. And you were only wrong by about 12,000 miles (wrong Pole, lol). And none of this is any indictment against AGW.

And, of course, even if the Arctic ice was increasing, it would have no effect on sea levels since the Arctic ice is already floating in the ocean. It is the melting ice in the Antarctic and Greenland, which are on land, and pouring INTO the ocean that we have to worry about.

I would put money on the Great Lakes being under a mile of ice before the mile of ice disappears from Antarctica
