Florida Tops U.S. List for Risk in Climate Change Study

Mon, 2018-06-18 22:45 — Kathy Gilbeaux

Florida has more to lose with sea rise than anywhere else in the U.S., new study says

Florida stands to lose more homes — and real estate value — to sea level rise damage than any other state in the nation this century, according to a new study.

By 2045, nearly 64,000 homes in Florida face flooding every other day. Half of those are in South Florida.

If you buy a house now, before your new mortgage is paid you might have to regularly do the rolled-up-pants, shoes-in-hand commute that has become an enduring image of sea rise.

West Antarctic Ice Melt Poses Unique Threat to U.S.

News of Antarctica's accelerating ice melt garnered worldwide headlines yesterday, as scientists revealed that 3 trillion tons of ice has been lost to the sea since 1992 — mostly from the thawing West Antarctic Ice Sheet and Antarctic Peninsula.

Why it matters: The location of the ice melt is important for determining the future of coastal communities, according to climate scientists. And, due to West Antarctica melting, it turns out that the U.S. coastline will be hit extra hard . . .

Antarctic ice loss has tripled in a decade. If that continues, we are in serious trouble.

Antarctica’s ice sheet is melting at a rapidly increasing rate, now pouring more than 200 billion tons of ice into the ocean annually and raising sea levels a half-millimeter every year, a team of 80 scientists reported Wednesday.

Hurricanes Are Lingering Longer. That Makes Them More Dangerous.

A new study shows that storms are staying in one place longer, much like Hurricane Harvey did last year.

 . . . A study published Wednesday in the journal Nature focuses on what is known as translation speed, which measures how quickly a storm is moving over an area, say, from Miami to the Florida Panhandle. Between 1949 and 2016, tropical cyclone translation speeds declined 10 percent worldwide, the study says. The storms, in effect, are sticking around places for a longer period of time.

RECORD-BREAKING OCEAN HEAT FUELED HURRICANE HARVEY

In the weeks before Hurricane Harvey tore across the Gulf of Mexico and plowed into the Texas coast in August 2017, the Gulf's waters were warmer than any time on record, according to a new analysis led by the National Center for Atmospheric Research (NCAR).

These hotter-than-normal conditions supercharged the storm, fueling it with vast stores of moisture, the authors found. When it stalled near the Houston area, the resulting rains broke precipitation records and caused devastating flooding.

"We show, for the first time, that the volume of rain over land corresponds to the amount of water evaporated from the unusually warm ocean," said lead author Kevin Trenberth, an NCAR senior scientist. "As climate change continues to heat the oceans, we can expect more supercharged storms like Harvey."

Scientists Warn Bigger and Stronger Storms Ahead

caribbean360.com - May 23, 2018

American scientists studying past and future weather patterns have warned hurricane conditions could get bigger, stronger and wetter.

Researchers at the National Centre for Atmospheric Research (NCAR) have published a detailed analysis of how 22 recent hurricanes would change if they instead formed near the end of this century. And while each storm’s transformation would be unique, on balance, the hurricanes would become a little stronger, a little slower moving, and a lot wetter.

Hurricanes Are Strengthening Faster Than They Did 30 Years Ago

With the start of hurricane season just three weeks away — and memory of last year's disastrous storms still fresh — scientists reported that powerful hurricanes are strengthening faster than they did 30 years ago.

Four of the monster hurricanes last year (Harvey, Irma, Jose and Maria) all intensified rapidly — when the maximum wind speed increases at least 29 mph within 24 hours . . .

 . . . According to a study out this week, the main cause appears to be a natural climate phenomenon that warms the seawater where hurricanes typically intensify in the Atlantic.

Carbon dioxide — the gas scientists say is most responsible for global warming — reached its highest level in recorded history last month, at 410 parts per million.

This amount is highest in at least the past 800,000 years, according to the Scripps Institute of Oceanography. Prior to the onset of the Industrial Revolution, carbon dioxide levels had fluctuated over the millennia but had never exceeded 300 parts per million.
