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 . . .

U.S. Disaster-Response Force Stretched Thin as Hurricane Season Starts

Wed, 2018-06-13 18:21 — Kathy Gilbeaux

reuters.com - by Andy Sullivan - June 13, 2018

With the 2018 hurricane season already underway, FEMA is scrambling to hire more people who are willing to depart at a moment’s notice for assignments that can last months at a stretch.

Internal documents obtained through a Freedom of Information Act request show the agency's disaster-response force is understaffed by 26 percent. And as last year revealed, many of those who sign up don't always respond when needed.

The extraordinary string of domestic disasters in 2017 continues to weigh on the U.S. agency. With thousands of workers still out in the field, official figures show that 33 percent of FEMA’s disaster-response workforce is available for deployment, down from 56 percent at this time last year.

Some specialties are stretched especially thin: Only 13 percent of the workers who direct federal aid to pay for rebuilding costs after a disaster hits are currently available.

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.

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.

When Cheap Doesn’t Cut It: Why Energy Buyers Should Look at Value, not Just Cost

Figure 1: Distribution-scale solar costs more than wholesale power, but it costs less if you fairly value all benefits

rmi.org - by Titiaan Palazzi Thomas Koch Blank - May 1, 2018

“New Record Set for World’s Cheapest Solar.” A headline like this makes for great social media fodder. The downward trend in renewables prices is fantastic—it’s the most important driver for the growth of solar and wind energy.

However, when your business or utility is comparing different energy projects, looking at cost alone is not enough. Even energy projects at very low costs can be “out of the money” if the value created by a project is less than its cost.

How Storms, Missteps and an Ailing Grid Left Puerto Rico in the Dark

Mon, 2018-05-07 10:25 — Kathy Gilbeaux

A transmission tower and downed lines in the mountainous terrain of eastern Puerto Rico. Workers from the island and throughout the United States have worked to restore power after Hurricanes Irma and Maria last September.

It took months to restore electricity in Puerto Rico after hurricanes dealt a one-two punch. Many homes are still without power, and the system’s future is far from certain.

. . . After Maria and the hurricane that preceded it, called Irma, Puerto Rico all but slipped from the modern era . . .

. . . an examination of the power grid’s reconstruction — based on a review of hundreds of documents and interviews with dozens of public officials, utility experts and citizens across the island — shows how a series of decisions by federal and Puerto Rican authorities together sent the effort reeling on a course that would take months to correct. The human and economic damage wrought by all that time without power may be irreparable.

Earth's Carbon Dioxide Levels Continue to Soar, at Highest Point in 800,000 Years

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.
