Science

Doomsday Glacier Ice Shelf May Be Lost This Year

This article in LiveScience is an interview with marine geophysicist Robert Larter addressing the likely loss of the ice shelf around the Thwaites Glacier (aka “Doomsday Glacier”) quoting Larter:

“The last bit of ice shelf in front of the glacier is poised to disintegrate. We don't know quite how this ice shelf is going to break up, but it's definitely going to go. It's tearing away from the glacier at the moment, and its internal structure is getting more and more fragile. You can see the fractures and rifts growing in sequences of satellite images.”

Antarctic Ice Shelf Melting Worse Than Expected

This article in the journal Nature Communications reports that warm seawater under Antarctic ice shelves is causing more melting than earlier climate models predicted revising expectations for future sea level rise. This article from Science Daily provides a non-technical summary:

“Scientists have uncovered a hidden Antarctic threat that could accelerate global sea level rise far faster than expected. Deep beneath floating ice shelves, long channels carved into the ice appear to trap warmer ocean water, dramatically speeding up melting from below. Even regions of East Antarctica once considered relatively stable may be far more vulnerable than scientists realized. Researchers warn that current climate models may be missing this dangerous process entirely, meaning future sea level rise could be underestimated.”

Judge Blocks Dismantling of National Center for Atmospheric Research

This article in the Colorado Sun reports that a federal judge has ruled that the Trump administration’s proposed breakup of the National Center for Atmospheric Research (NCAR), which provides critical climate change services, was “arbitrary, capricious, an abuse of discretion, or otherwise not in accordance with law”.

Here is a link to the CFRP letter in support of NCAR.

Trump Administration Dismantling Deep Ocean Monitoring Network

This article in The New York Times describes how the Trump administration is dismantling a network of more than 900 deep sea monitoring devices, including those monitoring the condition of the Atlantic Meridional Overturning Circulation (AMOC), that was planned to continue for 25 years.

“Scientists have used data from the system to understand how the ocean is absorbing greenhouse gases from the atmosphere, how changes in ocean temperature such as marine heat waves might affect fisheries or signal bigger shifts in the climate, and coastal flooding along the East Coast.

National Policy

ASCE Flood Standard Adopted by International Code Council

This article in the Association of State Floodplain Managers newsletter describes the successful effort to convince the International Code Council to adopt the new flood standard developed by the American Society of Civil Engineers.

“Last week, a coalition of organizations, including ASFPM, secured a major win at the ICC Public Comment Hearings in Hartford, Connecticut, successfully defending the inclusion of ASCE 24-24 in the 2027 International Codes, including the Building, Residential, and Existing Building code volumes. The coalition was also successful in overturning a committee’s earlier decision to not include ASCE 24-24 in the International Residential Code.”

This YouTube video provides more information on ASCE 24-24.

SEC to Repeal Climate Disclosure Rule

This article in The New York Times describes the decision by the Securities and Exchange Commission to repeal a rule that requiring thousands of companies to disclose the risks they face from a warming planet, including risks to facilities from coastal storms and rising sea level, and how their operations contribute to climate change.

“If it had gone forward, the rule would have required all publicly traded companies to disclose whether they faced significant risks from climate change and its effects, including more frequent and more severe floods, wildfires and hurricanes. For example, a hotel chain would have had to inform investors of risks to waterfront properties from rising seas and storm surges.”

CFRP provided comments supporting the draft rule.

NOAA Predicts Below Normal Atlantic Hurricane Season

NOAA has announced its assessment of hurricane development this summer in the North Atlantic, concluding that a strong El Nino is likely to result in fewer hurricanes than a normal year.

“The agency is forecasting a total of 8-14 named storms (winds of 39 mph or higher). Of those, 3-6 are forecast to become hurricanes (winds of 74 mph or higher), including 1-3 major hurricanes (category 3, 4 or 5 with winds of 111 mph or higher). NOAA has a 70% confidence in these ranges. An average season has 14 named storms with seven hurricanes, including three major hurricanes.”

This article in The New York Times provides more information, as does this article in The Washington Post.

NOAA Links El Nino to Higher Sea Level Rise

This report from NOAA describes impacts of the projected El Nino event this summer including increased high tide flooding:

“During an El Niño, the trade winds weaken across the tropical Pacific, triggering Kelvin waves that travel eastward along the equator and then up the west coast of the Americas, warming the upper ocean and raising both sea surface temperatures and sea levels for several months or longer.”

Cuts to NOAA Threaten Hurricane Forecasts

This article in The Guardian describes concerns that funding cuts to NOAA threaten the quality of forecasts for heat and hurricanes over the coming months:

“But widespread reports show staffing cuts have forced NOAA’s National Weather Service to scale back satellites and balloon launches, key parts of the country’s data collection system. And shrunken climate programs threaten ocean buoy networks and other observation systems, experts say. Research into effects of the climate crisis on Earth’s systems is also being slashed, along with funding for researchers who analyze data and identify new sources.”

NRDC Publishes Community Resilience Guide

The Natural Resources Defense Council has published “Rebuilding Safer: A Guide to State and Local Adaptation” highlighting practical opportunities for strengthening disaster resilience through policy, governance, and investment. Opportunities are identified in four major areas:

  • Understand the risk and vulnerability. Build a clear picture of risk, including hazards, exposures, and vulnerabilities, to guide decisions and target investments.

  • Integrate adaptation into existing systems and processes. Embed climate adaptation into existing planning, permitting, codes, and capital budgeting.

  • Create new systems and processes to increase state and local capacity to adapt. Establish durable rules, authorities, and incentives ensuring that public and private decisions are informed by risk and can therefore stand the test of time.

  • Pioneer transformative adaptation approaches. Big problems require big solutions— bonds, tax structures, climate superfunds, and risk-transfer instruments—as means to fund long term climate adaptation.

New Estimates of Impacts of Coastal Storms on Homes

This new report from risk management firm Cotality provides estimates of the number of homes in coastal states at risk of flooding due to storm surge, finding over 6 million homes at risk today with a reconstruction cost estimate of $2.1 trillion.

“Florida is the undisputed epicenter of hurricane risk, leading the nation with approximately 8.25 million homes at risk of wind damage and 2.47 million homes at risk of storm surge. This storm surge risk in Florida represents $747.6 billion in RCV, [reconstruction cost value] which is over three times higher than the second most at-risk state of Louisiana. Texas ranks second for hurricane wind risk with 4.76 million homes, followed closely by North Carolina.”

The report also points to the high percentage of homes in coastal flood risk areas that are below the 100 year flood elevation:

“A critical factor in assessing this vulnerability is examining the elevation of a home relative to base flood elevation. Only 38.2% of homes in coastal flood zones are elevated above the 100-year base flood elevation. This means a staggering 61.8% of coastal residences sit below this critical safety line, highlighting massive structural vulnerability right on the coast.”

New Marsh Modelling Community of Practice

The Program for Local Adaptation to Changing Environments (PLACE) at Mississippi State University, supported by NOAA and other partners, has established a new Marsh Modelling Community of Practice to “advance marsh models for coastal decision-making, delivering a nationwide framework for applying marsh models.”

You can sign up for the Community of Practice here.

Floodplain Managers React to FEMA Review Council Report

This article from the newsletter of the Association of State Floodplain Managers (ASFPM) describes what ASFPM thinks about the report noting:

“While the report contains several constructive recommendations, ASFPM is deeply concerned that some of the proposals reflect a misunderstanding of how floodplain management, hazard mitigation, and the NFIP function in practice.”

Some of the concerns with the report include a failure to address the debt carried by the National Flood Insurance Program, failure to recommend funding for improved flood mapping, and failure to fully support the Community Rating System.

In a related article, ASFPM Director Chad Berginnis offers his top ten recommendations for improving FEMA.

State and Local

New Jersey Reconsiders Critical Coastal Rules

The State of New Jersey has published a notice delaying by one year the final Resilient Environment and Landscapes (REAL) regulations that respond to climate change by considering risks such as sea-level rise and chronic flooding and facilitate climate resilience by supporting green infrastructure and renewable energy. The notice announces a public hearing and comment period, explaining:

“The Department seeks to extend the legacy period to allow the Department to determine if targeted amendments to the NJPACT REAL rules would streamline or simplify permit reviews, in accordance with the directives of Governor Sherrill’s Executive Order 5, while still serving the rules’ critical goals.”

Maryland and Chesapeake Bay Harmed by Repeal of Endangerment Finding

This opinion piece in Maryland Matters by the President of the Chesapeake Bay Foundation describes how Trump administration repeal of the Endangerment Finding, providing a legal basis for control of greenhouse gas emissions, poses a risk to Maryland and the Chesapeake Bay, including risks from rising sea level.

“Marylanders should be worried about the federal government’s recent repeal of the endangerment finding, a landmark finding that heat-trapping air pollution endangers public health and the environment. This weakens work to prevent pollution that’s driving sea level rise, harming the Bay and threatening the pillars of Maryland’s economy. That is why the Chesapeake Bay Foundation, represented by Earthjustice, has joined a lawsuit to defend the endangerment finding in court.”

New Jersey State of the Climate Report Released

Rutgers University has released a new State of the Climate report for the State of New Jersey including two sets of estimates for sea level rise:

“This report provides two approaches for estimating the likely range of sea-level rise in New Jersey, one excluding rapid-ice sheet loss processes and one including potential rapid ice sheet loss processes….The inclusion of these processes represents projections with unknown likelihood but are at the forefront of scientific discovery, such as marine ice-cliff instability, that could significantly accelerate sea-level rise. These two approaches were included so that decisionmakers can prepare for sea-level rise projections in line with their specific risk tolerance.”

Under a medium global warming scenario, the report estimates sea level rise in the range of .7-1.3 feet by 2050 with a second estimate based on rapid ice sheet loss of 1.9 feet. For 2100, the report estimates a range of 2.2-3.8 feet with an ice sheet loss estimate of 4.5 feet.

Southeastern State Plans to Conserve Salt Marshes

This article from the Pew Charitable Trusts describes the new plans that nonprofit organizations in southeastern coastal states have developed to conserve salt marshes.

“The plans, which are part of an effort to conserve and restore 1 million acres of salt marshes—roughly the size of Grand Canyon National Park—were developed by state-based member teams from the South Atlantic Salt Marsh Initiative (SASMI), a group of more than 400 stakeholders working to save marshes from encroaching seas, polluted runoff, unsustainable development, and other threats.”

New Orleans Relocation Impacts on Fishermen

This opinion piece in Grist refers to a recent journal article describing the need to begin the process of relocating New Orleans with concern for impacts on the fishing community in the area.

“For the fishermen in the state of Louisiana, the loss of, or not being able to use New Orleans as a hub, as a source of infrastructure, as a place to sell seafood — New Orleans consumes a lot of seafood as a market — would be devastating,” said Jeffrey Plumlee, an assistant professor at the School of Renewable Natural Resources at Louisiana State University.”

North Carolina Considers Options to Save Beach Houses

This article from Energy and Environment News describes the steady loss of homes to rising seas along the coast of North Carolina and describes some of the options the State of North Carolina is considering to reduce these losses including beach nourishment and adding a jetty.

“The destruction of houses on Cape Hatteras has raised questions about whether taxpayer dollars should be responsible for protecting private property that many people say shouldn’t stand so close to the shore anyway. Buxton beach is an erosion hot spot on a barrier island that erodes and moves — the beach loses approximately 10 to 15 feet of sand to the ocean every year, a natural process exacerbated by climate change and sea-level rise.”

North Carolina Implementing Sunny Day Flooding Program

This article from the North Carolina Coastal Federation describes a new program focusing on building awareness of coastal flooding that occurs on sunny days due to tides that are especially high due to the changing position of the sun and moon.

“The Sunny Day Flooding Project launched in 2021 “to understand and address the incidence and impacts of chronic coastal flooding. The team collects measurements, holds interviews and conducts surveys to better understand the effect of floods on residents, economies and human health. They communicate the flood risks through its flood alert system and king tides program.”

Mobile, Alabama Supported by NASA Sea Level Rise Data

This NASA video describes the work NASA is doing to provide Mobile, Alabama with useful information about sea level rise risks.

The Coastal Flood Resilience Project is a network of nonprofit organizations working for stronger federal, state, and local programs to prepare for coastal storm flooding and rising sea levels along the coast of the United States.
