A crucial crack in an Antarctic ice sheet grew 11 miles in only 6 days.

Some highlights:

“I was elected to represent the citizens of Pittsburgh, not Paris.”

Pittsburgh’s votes went mostly to Hillary Clinton. She won 55.9 percent of votes in Allegheny County. Note that the Paris Agreement encompasses people from nearly 200 countries, not just the city where it was drafted.

“The bottom line is the Paris accord is very unfair at the highest level to the United States.”

Other countries think U.S. involvement is extremely fair. The United States blows every other country away in terms of per capita emissions.

“This agreement is less about the climate and more about other countries gaining an economic advantage over the United States.”

Actually, the economic advantages of combating climate change are well documented. Companies like Exxon, Google, and even Tiffany & Co. asked Trump to stay in the agreement.

And, just for fun, a comment from Scott Pruitt:

“America finally has a leader who answers only to the people.”

Nearly 70 percent of Americans were on board with the Paris Agreement. Only 45 percent voted for Trump.

Antarctica is about to lose a chunk of ice the size of Delaware

A massive crack in one of Antarctica’s largest ice shelves has grown exponentially in recent months, and scientists worry a break-off could destabilize the entire structure.

For two years, United Kingdom-based Project MIDAS has been monitoring a large rift in the Larsen C ice shelf, located on the northern end of the Antarctic peninsula. And if the project’s latest findings are any indication, Larsen C could be headed for a similar fate as nearby Larsen A and Larsen B, which collapsed and disintegrated in 1995 and 2002, respectively.

Since March, the last time satellites were able to observe Larsen C, Project MIDAS said the crack has extended nearly 14 miles ― about three miles per month.

“As this rift continues to extend, it will eventually cause a large section of the ice shelf to break away as an iceberg,” according to the report.

Now, measuring some 80 miles in length, the crack could ultimately dislodge a chunk of ice the size of Delaware, The Washington Post reports.

At 21,000 square miles, Larsen C is the largest ice shelf in the region, according to a 2015 report. In recent years, however, what was once a small fracture has rapidly moved through the frozen structure, widening to more than 1,000 feet. The crack, scientists wrote in last year’s report, “is likely in the near future to generate the largest calving event since the 1980s and result in a new minimum area for the ice shelf.”

Project MIDAS previously estimated the breakaway would remove between 9 and 12 percent of the ice shelf.

“The trajectory of the rift now implies that the higher of these two estimates is more likely,” the MIDAS team wrote in its post last week. “Computer modeling suggests that the remaining ice could become unstable, and that Larsen C may follow the example of its neighbor Larsen B, which disintegrated in 2002 following a similar rift-induced calving event.”

In 2014, more than a decade after its collapse, scientists determined the event was triggered by warming air temperatures.

Since ice shelves float on the ocean’s surface, the calving event wouldn’t immediately raise sea levels. An event of this scale, however, could destabilize the entire shelf, resulting in its disintegration and the release of the glacier ice it holds back ― ultimately raising sea levels.

As for when the iceberg will make its break, that’s hard to say, Martin O’Leary, a glaciologist at Swansea University in the United Kingdom, told The Washington Post.

It’s a lot like predicting an earthquake ― exact timings are hard to come by,” he told the Post. “Probably not tomorrow, probably not more than a few years.”

When it does, it could spark a vanishing act that resembles what happened at Larsen B, which NASA highlights in the video below:
