Rapid Retreat of an Antarctic Glacier Could Lead to Rapid Sea Level Rise

An Antarctic glacier has retreated nearly 3 miles in 22 years, and scientists worry that the rapid retreat could lead to climate-driven collapse.

Researchers studying radar data recorded by a satellite say the Denman Glacier in East Antarctica has been experiencing rapid melting. The pace could speed up even more if the glacier’s western slope, which has a deep trough and slope shape that makes it susceptible to rapid retreat, comes into play. If the whole glacier were to collapse into the sea, worldwide sea levels would rise by up to five feet.

Eric Rignot, a study co-author and scientist at the University of California, Irvine (UCI), told UCI News, “The ice in West Antarctica has been melting faster in recent years, but the sheer size of Denman Glacier means its potential impact on long-term sea level rise is just as significant.”

The researchers, whose study was published in Geophysical Research Letters, will continue to monitor the glacier.

Sea Level Rise Scientists Plan to Retreat from Vulnerable Research Facility in New Jersey

Sea level rise flooding isn’t just a problem for coastal governments or real estate owners, it’s also a challenge for research scientists.

According to a NJSPOTLIGHT report, researchers at the Rutgers University Marine Field Station, located in the middle of a marsh near Tuckerton, New Jersey, are seeking a federal grant to enable them to work inland. The researchers are eager to move because sea level rise-driven flooding frequently inundates the only access road and puts the facility itself at risk.

Lisa Auermuller, who works at the field station, told NJSPOTLIGHT reporter Jon Hurdle that retreat is the right thing to do considering that their mission is to study the impact of rising seas on coastal communities. “How long can you keep telling people that they need to pay attention to this when we’re not paying attention to it ourselves?” she asked. “We need to be leading by example.”

NASA: Greenland and Antarctica Ice Melt Speeding Up Sea Level Rise

NASA reported this week that Greenland and Antarctica ice sheets are melting six times faster than they did in the 1990s, a development that could have a severe impact on coastal real estate.

NASA scientists published their statement on the Jet Propulsion Laboratory website in response to a study by the Intergovernmental Panel on Climate Change that showed Greenland and Antarctica combined lost 6.4 trillion tons of ice in three decades. “Unabated, this rate of melting could cause flooding that affects hundreds of millions of people by 2100,” according to NASA.

Researchers used observations from 11 satellite’s that monitor Greenland and Antarctica ice loss to arrive at their disturbing conclusion. They calculate that the meltwater has raised global sea level by .7 inches. This doesn’t sound like much, but it can have a significant effect on coastal populations. “Every centimeter of sea level rise leads to coastal flooding and coastal erosion, disrupting people’s lives around the planet,” said Prof. Andrew Shepherd, a scientist at the University of Leeds.

Ice melt isn’t the only factor fueling sea level rise. Ocean heating and expansion and the melting of smaller land-based glaciers also contribute to higher seas.

Coastal Real Estate in Greater Peril as Antarctic and Greenland Ice-Melt Follows Worst Case Scenario

One of the major questions for coastal governments and real estate owners is: How fast will sea level rise flooding advance? According to the latest analysis by the United Nation’s Intragovernmental Panel on Climate Change (IPCC), the answer is: Likely a lot sooner than we’d hoped.

IPCC scientists analyzed data from Antarctica and Greenland and determined that land-based ice and snow are melting six times faster than they did in the 1990s. This is in line with the group’s worst-case scenario.

At this pace of melting, IPCC experts estimate the oceans will rise nearly 7 extra inches over the 21 inches (1.75 feet) they’ve set as their mid-range global sea level rise prediction for the end of the century. That’s a total of 2 1/4 feet of sea level rise.

Andrew Shepherd, a professor of Earth Observations at the University of Leeds, told the Guardian newspaper that if sea levels rise as predicted in the latest estimate, 400 million people will be impacted by coastal flooding; that’s up from 360 million people earlier predicted. “These are not unlikely events with small impacts,” he told the paper. “They are already under way and will be devastating for coastal communities.”

Land-based ice and snow melting in Greenland and Antarctic contribute about a third of the global sea level rise total. The rest comes from expansion of the oceans as they warm and runoff from smaller glaciers.

Greenland and Antarctica seem like a long way away, but their meltwaters could ultimately decide the fate of billions of dollars worth of coastal real estate. To make informed decisions, property owners in at-risk areas need to keep up to date on the pace of ice and snow melt and the stability of their glaciers.

UN Climate Report Makes Dire Prediction for Climate Change and Sea Level Rise

Humans need to nearly half greenhouse gas emissions over the next decade or face dire climate consequences. That’s the warning issued by the United Nations’ World Meteorological Organization which released its annual State of the Global Climate report this week in New York.

“Greenhouse gas concentrations are at the highest level in 3 million years – when the Earth’s temperature was as much as 3 degrees hotter and sea levels some 15 meters higher,” said UN Secretary-General Antonio Guterres. “We count the cost in human lives and livelihoods as droughts, wildfires, floods and extreme storms take their deadly toll.”

The WMO’s report discussed the many signs of climate change experienced around the globe in 2019, including increased heating of land and ocean, accelerated sea level rise, and ice melt. Each decade since 1980 has set a global heat record, and 2016 was the hottest year on record. Scientists say that record will likely be broken in the next five years.

“We need all countries to demonstrate that we can achieve emissions reductions of 45 percent from 2010 levels this decade and that we will reach net-zero emissions by mid-century. We know this is the only way to limit global heating to 1.5 degrees Celsius,” Secretary Guterres said.

WMO Secretary-General Petteri Taalas said not heeding reducing the release of greenhouse gases will continue to hasten sea level rise. “Reported record temperatures in Antarctica were accompanied by large-scale ice melt and the fracturing of a glacier which will have repercussions for sea level rise,” Secretary Taalas said.

The UN and WMO are calling on developed countries to commit $100 billion a year toward developing renewable energy sources and green technologies.

Coronavirus Failures Reveal the Same Shortcomings Found in Federal Climate Change and Sea Level Rise Responses

Some leaders, almost exclusively conservatives, in the federal government call it a hoax or fake news. They refuse to acknowledge its existence and eliminate personnel and programs that could provide an effective response. When they should be mounting an effective response, they avert their eyes. Meanwhile, the problem grows worse each and every day.

This narrative is as true for the coronavirus, a threat that’s growing exponentially, as it is for climate change and sea level rise that, too, are growing worse each and every day. Both pose a real and present danger to public health and the economy. And both can only be brought under control by leaders who listen to scientists and implement plans based on their counsel.

The unfortunate thing in both cases, is that while the denialists and their supporters don’t take the problems seriously — and often obstruct and undermine those who do — for their selfish political and financial gains, the virus and the ever-warming planet continue to pose threats to life and property.

There is no mistaking that the failures that set back an effective, fact-based response to coronavirus, with costs that are playing out before our own eyes, are the same ones that are going to eventually catch up to us in climate change and sea level rise.

In the case of climate change and sea level rise, scientists are sounding a blaring warning alarm as is the planet. On a global basis, humanity is continually setting records for the burning of the fossil fuels that cause global warming, which in turns melts land-based ice and snow and causes the oceans to expand. The planet is responding by continuously breaking temperature records on land and sea and by increasing the frequency and intensity of weather disasters, such as droughts, floods and hurricanes. Many communities are also already being forced to make hard decisions as sea levels rise floods valuable real estate.

The lack of responsible and effective federal leadership that respects scientific facts is forcing state and local governments to draft and implement their own solutions. Just as in the case of coronavirus, the lack of federal leadership and the reliance on a patchwork response, puts everyone at-risk.

The lesson to be learned from coronavirus is that the world cannot afford national leaders who deny basic science. They put our lives, our livelihoods, our financial futures, and, ultimately, the only planet we’ll ever know at risk of total destruction. In the real estate world, we’re already seeing climate change and sea level rise flooding putting enormous stress on the flood insurance system, which could cause it to fail — an eventuality that would lock up the mortgage market and cause real estate values to plummet.

Unless we shove aside the climate change and sea level rise denialists and mount an aggressive national response to the roots of the problems now, the markets will most certainly start to collapse. The damage is sure to be much worse and longer-lasting than the damage now being inflicted by coronavirus.

Public Activism Can Help Mitigate Sea Level Rise Flooding Problems

Owners of real estate in areas now experiencing sea level rise flooding can fight back by teaming up and going public with their plight. That’s the experience of an Ocean City, NJ, woman whose neighborhood flooded on a regular basis.

Suzanne Hornick shared her story with Samantha Harrington, a reporter for the Yale Climate Connections website. Hornick said the flooding in her neighborhood has worsened over the decades her family has owned property in Ocean City. Fed up, she fought back by creating a Facebook page that documented the flooding and by joining with her neighbors to form the Ocean City, NJ, Flooding Committee. The committee demanded that the city deal with the problem. They even distributed “Fix our flooding now” signs that residents displayed on their lawns.

By aggressively demanding relief, Hornick and her group developed a contentious relationship with local city officials. Then they had a breakthrough when she consulted with Tom Herrington, a coastal scientist and director of the Urban Coast Institute at Monmouth University. Herrington, who grew up in Ocean City, advised Hornick and the group about how to gather tidal and flood data that could be used to convince the city to take concrete steps to solve the flooding problem wherever possible, which it did. As a result of all their efforts, Hornick says she hasn’t had flooding on her street in a year.

Hornick, the group, and the city can’t rest on their laurels, however. They still have to take additional steps to address the continuously rising seas.

With sea level rise flooding on the rise in communities along the Atlantic, Pacific and Gulf of Mexico coastlines, real estate owners can’t afford to take a passive approach when it comes to protecting what for most is their greatest investment: Their homes. Gathering data, taking photos, building a website and forming flood-focused interest groups, is a great way to appeal to officials and the public for relief.

Insurers and Mortgage Providers Are Shifting Sea Level Rise Flooding Risk to Government-Run Programs and, Ultimately, Taxpayers

A recent article by Naveena Sadasivam published in Grist examines in-depth the way insurance companies and mortgage providers are shifting the risk from sea level rise flooding and other climate change-related disasters to government run insurers and, ultimately, taxpayers. This could have grave consequences for coastal real estate markets.

There are several mechanisms they’re using to unburden themselves of the risks, according to the Grist article. One way is for private insurers to abandon risky areas, leaving states with subsidized state insurance programs — such as California, Florida and Texas — to pick up the burden. Another way is for mortgage providers to make loans in high-risk areas and then sell them to Fannie Mae and Freddie Mac, which guarantee about 50 percent of the country’s $10 trillion mortgage market.

Unfortunately, many of the state-subsidized insurance programs are underfunded. If a natural disaster hits, they could go broke, leaving taxpayers to pick up the tab. The Fannie Mae and Freddie Mac mortgage programs are also at risk of being destroyed from disasters. If they fail, taxpayers will likely have to cough up billions of dollars in bailout money.

According to the Grist article, “Experts say if these climate risks are left unaddressed, the combined effects could ripple across the economy in ways that mirror the subprime mortgage crisis of 2007.”

Mortgage providers require buyers and owners to purchase flood insurance. If insurance becomes prohibitively expensive or unreliable, coastal real estate markets could lock up and property values could plummet.

When it Comes to Sea Level Rise Real Estate, Timing is (almost) Everything

When buyers are considering purchasing coastal properties in areas that are forecast to experience sea level rise flooding in years or decades to come, one of the questions they have to ask themselves is: “How long do I expect to enjoy the property?”

This question came to light bluntly when I had lunch today with friends who live on an island in San Francisco Bay. My friends, a husband and wife in their mid-60s, said they weren’t too concerned about sea level rise — though they know it’s coming — because it’s not predicted to actually flood their property for another 50 years. As the wife put it, “We’re pretty sure we’ll be dead by then.”

Actuarial tables say she’s probably right. As long as the current sea level rise forecasts hold, they probably will get to enjoy their property for the remainder of their lives.

Sea level rise vs. life expectancy is an important issue for buyers and owners in coastal areas to consider when they’re pondering their real estate options. Sea level rise forecasts are putting a potential expiration date on many communities along the Atlantic, Pacific and Gulf of Mexico coastlines. Knowing when rising seas will begin to inundate cities and towns is critically important for buyers and sellers. Other factors that have to be considered are how will sea level rise impact carrying costs, such as home maintenance, taxes, flood insurance and condo and homeowners’ association fees.

Combining sea level rise forecasts, your life expectancy, and your ability to afford the carrying costs as you age, is a good way for buyers and owners to tell if it makes sense to get involved or stay involved in real estate in a coastal community. When you’re talking about such fun areas to live in, this level of analysis can sound like a real downer, but not taking this dry-eyed look at the sea level rise situation could lead to an even greater downer: financial disaster.

This issue is discussed in greater detail in “7 Sea Level Rise Real Estate Questions.”

Florida Senate Bill Calling for State Level Sea Level Rise Office and Task Force Advances in Tallahassee

With up to 3 feet of sea level rise predicted in the next 40 years and $300 billion worth of real estate at risk due to flooding by the end of this century, Florida continues to furiously work to address this offshoot of global warming.

The state went from essentially denying the existence of climate change and sea level rise during Gov. Rick Scott’s tenure to playing catchup when Gov. Ron DeSantis took office in early 2019. DeSantis was roundly applauded for appointing a Chief Resilience Officer to take on the problems posed by sea level rise flooding and climate change. Now the state senate is advancing a bill that would create a Statewide Office of Resiliency and Statewide Sea-Level Rise Task Force .

If the bill passes, the Office of Resiliency would create sea level rise projections that would be reported directly to the governor for use in policy-making. The task force would be comprised of nine members, including the Chief Resilience Officer and Department of Environmental Protection’s Chief Science Officer.

Sen. Tom Lee, the lead sponsor of the bill (SB7016), told FloridaPolitics.com, “Whoever picks up the ball and begins to run with it here will have to hit the pavement running … I acknowledge that.”

In the absence of federal and state leadership and response coordination, counties, local governments and private interests have formed regional commissions on their own to address sea level rise flooding, which is already threatening real estate, roads and infrastructure in many communities. Buyers, sellers, owners and real estate agents need to stay informed about their activities. Their ability to address sea level rise flooding will have a substantial impact on individual properties, neighborhoods, taxes, and flood insurance.
