New york city’s fate is closely tied to antarctic ice, climate scientists warn – the washington post electricity electricity goodness


Using computer projections to simulate thousands of storms in potential future climates, researchers found that storms would be more likely to swerve away from the city. The trouble is the storms that do approach will, on average, be more powerful. And all storms that hit New York, regardless of their power, will start at a higher baseline, as they’ll be traveling on seas that have gas bloating risen due to climate change.

“Ultimately, the balance of evidence for our study is probably bad news for New York,” Andra Garner, the Rutgers University researcher who led the study, wrote in a comment to The Washington Post. “Although we do find minimal changes electricity edison to future storm surge because of a compensation between shifting storm tracks and increasing storm intensity, we find drastic increases to overall flood heights due to rising sea-levels, which we calculate by combining storm surge with potential future sea-levels.”

The research predicts sea levels will rise steadily all the way out to the year 2300. The size of that rise, however, depends in part on the stability of Antarctica, which features large volumes of ice grounded below sea level in regions susceptible to warm ocean water. If those sections someday collapse into the ocean gas under 2 dollars, all the ice sitting above sea level will drive a potentially large sea level rise.

Garner conducted the study with colleagues from Rutgers, Pennsylvania State University, the Massachusetts Institute of Technology, Princeton University, the University of Massachusetts at Amherst, the Woods Hole Oceanographic Institution, and Nanyang Technological University. The research was published in the journal Proceedings of the National Academy of Sciences.

The group of experts includes not only hurricane specialists but also two glaciologists, the University of Massachusetts, Amherst’s Rob DeConto and Penn State’s David Pollard, who have recently produced a new simulation of the potential melting of the Antarctic ice sheet, one suggesting the potential for an over 3 foot contribution to global sea level gas bubble retinal detachment in this century, and far more in future centuries. (This is well beyond prior expectations from global bodies like the United Nations’ Intergovernmental Panel on Climate Change.)

Specifically, the work found that the one-in-500-years flood height at the Battery, a park in southern Manhattan fronting the harbor, could range from 13.1 to 16.7 feet by the year 2100, and 16.4 to 50.5 feet by the year 2300. Much of the range in these gas 2015 estimates, and particularly the enormous range in the latter estimate, has to do with what happens to Antarctica. (The sea-level-rise scenarios also depend on how much humans emit to the atmosphere in the coming years.)

“The three most important results to me are that sea level rise has already caused a big jump in flood risk; another real jump is on the way no matter what; and the size of that jump depends a lot on how much more climate pollution we put in the air,” he wrote. “That could especially be true in the worst-case scenario of an unstable Antarctica.”

“It could be seen as good news that more storms might steer away from New York,” added Richard Alley, a Penn State glaciologist who was a co-author of the study. “It might be seen as bad news in the other places where the storms go instead. My impression is that the rare, huge storm is the most worrisome, and that having bigger storms that gas x dosage pregnancy usually steer away from the city would leave the possibility of an occasional Sandy-type left turn bringing especially large damages to a city that had started to forget the last big hit.”
