Study of Antarctic Sea Ice Collapse Warns of Potential 10-Foot Sea Rise

The faster the ocean warms, the faster key Antarctic glaciers will disintegrate.

A stunning new study on Antarctic sea ice collapse greatly raises the risk of a 10-foot sea level rise this century if President Donald Trump’s climate policies aren’t quickly reversed.

Warming ocean waters drove a 6-fold increase in annual ice mass loss from the Antarctic ice sheet between 1979 and 2017, according to a new study in the Proceedings of the National Academy of Sciences.

It’s been known for a while that the West Antarctic Ice Sheet (WAIS) was unstable and collapsing at an accelerating rate due to global warming. But the new study finds that parts of the vastly larger East Antarctic Ice Sheet (EAIS) are also disintegrating.

California Utility Firm Suspected of Starting Deadly Wildfires Goes Bankrupt

Pacific Gas and Electric, which supplies 16 million residents, is under investigation for its role in the Camp fire and others

theguardian.com - by Vivian Ho - January 14, 2019

The utility company that services more than a third of California announced on Monday it plans to file for bankruptcy by the end of the month. Several deadly wildfires believed to have been caused by the company left it with potential liabilities of at least $30bn.

The board of directors of Pacific Gas and Electric (PG&E) has determined that the move “is ultimately the only viable option to restore PG&E’s financial stability to fund ongoing operations and provide safe service to customers”, the San Francisco-based company stated in a filing at the Security and Exchange Commission.

 . . . The increasing visibility of climate change, combined with bleak scientific reports and rising carbon dioxide emissions, is taking a toll on mental health, especially among young people, who are increasingly losing hope for their future. Experts call it “climate grief,” depression, anxiety and mourning over climate change.

New Report Strengthens Economic Case for Flood-Prepared Infrastructure

           

Hurricane Floyd submerged the Greenville, North Carolina, water treatment plant in 1999. Following that event, the city used a federal grant to construct a berm and pumping station to protect the plant.  Dave Gatley/Federal Emergency Management Agency

Mitigation projects yield positive return on investment in coastal, inland states

From elevating roadways in Nebraska to moving wastewater treatment plants away from flood plains in Iowa, proactive measures before flooding can provide a major return on investment, according to a new report from the National Institute of Building Sciences (NIBS). The report, “Natural Hazard Mitigation Saves: Utilities and Transportation Infrastructure,” provides analysis and key examples that underscore the benefits of investing in mitigation measures.

fastcompany.com - by Katharine Schwab - November 15, 2018

 . . . One Concern is launching a machine learning platform that provides cities with specialized maps to help emergency crews decide where to focus their efforts in a flood. The maps update in real-time based on data about where water is flowing to estimate where people need help the most. It’s the latest in a wave of AI-powered tools aimed at helping cities prepare for an era of severe, and increasingly frequent, disasters.

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

axios.com - by Andrew Freedman - June 14, 2018

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 . . .

Hurricanes Are Strengthening Faster Than They Did 30 Years Ago

                   

A new study found that hurricanes intensify more quickly now than they did 30 years ago. Hurricanes from 2017 like Irma (center), and Jose (right) are examples of these types of hurricanes. Hurricane Katia is seen on the left.  (Photo: NOAA)

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.

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

           

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.

Wind and Solar Costs Continue to Drop Below Fossil Fuels. What Barriers Remain for a Low-Carbon Grid?

           

Energy Innovation's Michael O'Boyle and Silvio Marcacci outline the barriers to high-penetration wind and solar in the least-cost era

The following is a viewpoint from Michael O'Boyle, electricity policy manager for Energy Innovation, and Silvio Marcacci, communications director for Energy Innovation

utilitydive.com - by Michael O'Boyle, Silvio Marcacci - March 21, 2018

Wind and solar are now cheaper than virtually anyone predicted, and renewable technologies have reached an inflection point: Rapid cost declines made renewable energy the cheapest available sources of new electricity, even without subsidies, in 2017.  In many locations across America, building new wind energy projects is cheaper than running existing coal-fired power plants.
