Climate Ready: Evidence in NYC shows rapid glacier melt is leading to real-world effects

NEW YORK CITY (WABC) — It’s not just in the movies; the ice on our planet is melting faster than we ever thought possible.

This melting is not just taking place at the North and South Poles.

“Everything from the relatively small glaciers that we’re use to looking iconically at, to the Alps, the Rockies, Alaska,” Robin Bell, geophysicist and glaciologist, said.

[…]

“There’s a tide gauge down at the Staten Island Ferry Terminal,” said Bell. “And sea levels have just been going up.”

[…]

New York City’s history with glaciers goes much further back.

“About 20,000 years ago, this whole area was under ice,” Steven Jaret, research associate at the American Museum of Natural History, said. “It would have been here about 1,000 to 2,000 feet thick.”

In parts of New York State, more than a mile and a half of ice covered what is now ground level, which is more than four times the height of one World Trade Center.

The article goes on to describe all of the breathtaking evidence of catastrophic glacier melting in and around New York City: Glacial erraticsglacial striations, more glacial erratics… Oddly enough they failed to mention that Long Island is basically a terminal moraine. They even included a cute video, with clips from the Ice Age cartoons.

Evidence of Late Pleistocene “rapid glacier melt” in modern-day New York City “is leading to real-world effects” about as much as the presence of Ordovician Period marine fossils on Mount Everest leads to evidence of Noah’s Flood.

Regarding sea level rise… When this much ice melted…

Figure 1. Late Pleistocene to Early Holocene deglaciation. (Illinois State Museum)

Sea level rose at a rapid rate of about 11 mm/yr over a period of about 10,000 years…

Figure 2. Global seal level rise during Holocene Transgression. Meltwater Pulse 1A (MWP 1A) occurred ~14.6 kya. Note the error bar is ±12 meters. Older is toward the right.
(Siddall et al., 2003)

Zooming in on the past 7,000 years (older is toward the left), we can see that the Late Pleistocene rapid sea level rise peaked between 6,000 and 5,000 years ago during the Holocene Climatic Optimum.

Figure 3. Global last 7,000 years, error bars omitted (Brock et al, 2008 after Sidall et al., 2003). Older is toward the left. Jevrejeva et al., 2014 (J14) is overlaid in red at the same scale. Ljungqvist, 2010 nothern hemisphere climate reconstruction is also overlaid. The relatively large swings in SLR over the past 4,000 years are clearly consistent with the millennial scale Holocene climate cycle.

About 1,000 years ago as the climate transitioned from the Medieval Warm Period to the Little Ice Age, sea level fell. by as much as 6 meters, before beginning to slowly rise again in the mid-1800’s.

Figure 4. Jevrejeva et al., 2014 (J14, red) and Church & White, 2011 (CW11, green).

Here’s a plot of CW11 shifted to the same datum as J14:

Figure 5. J14 vs CW11. 310 mm is less than the length of an Estwing rock pick. The green curve is CW11’s pentadal (5-yr) average. The red curve is J14’s pentadal average. The CW11 y-axis is shifted up 100 mm to tie J14.

About 13 inches of sea level rise over a 150 year period.

This brings us back to New York City…

“There’s a tide gauge down at the Staten Island Ferry Terminal,” said Bell. “And sea levels have just been going up.”

There is? Better let NOAA know about it…

Let’s take a peak at the actual tide gauges:

Figure 6. Montauk 3.60 mm/yr
The relative sea level trend is 2.94 millimeters/year with a 95% confidence interval of +/- 0.09 mm/yr based on monthly mean sea level data from1856 to 2024 which is equivalent to a change of 0.96 feet in 100 years.

The Battery 2.94 mm/yr

The Battery has the longest record length at nearly 170 years…. A steady rate of 2.94 ±0.09 mm/yr, starting 47 years prior to this climatic catastrophe:

Wikipedia

Of course, that 2.94 ±0.09 mm/yr is a combination of the water moving up and the land moving down.

NASA-Led Study Pinpoints Areas of New York City Sinking, Rising

Sept. 27, 2023

Scientists using space-based radar found that land in New York City is sinking at varying rates from human and natural factors. A few spots are rising.

Parts of the New York City metropolitan area are sinking and rising at different rates due to factors ranging from land-use practices to long-lost glaciers, scientists have found. While the elevation changes seem small – fractions of inches per year – they can enhance or diminish local flood risk linked to sea level rise.

The new study was published Wednesday in Science Advances by a team of researchers from NASA’s Jet Propulsion Laboratory in Southern California and Rutgers University in New Jersey.

[…]

The scientists found that on average the metropolitan area subsided by about 0.06 inches (1.6 millimeters) per year – about the same amount that a toenail grows in a month.

[…]

NASA JPL

So, we can knock 1.6 mm/yr off of the 2.94 mm/yr, reducing the actual rise in sea level elevation to 1.34 mm/yr.

Figure 9. “Mapping vertical land motion across the New York City area, researchers found the land sinking (indicated in blue) by about 0.06 inches (1.6 millimeters) per year on average. They also detected modest uplift (shown in red) in Queens and Brooklyn. White dotted lines indicate county/borough borders.

In the Science Advances paper, the “scientists” claimed that sea level rise at The Battery is accelerating.

During the 20th century, relative sea level at the Battery tide gauge in Manhattan, New York City increased at a rate of about 3.1 mm/year. From 2000 to 2022, that rate has increased to 4.4 mm/year. About 1.5 ± 0.2 mm/year of this rate has been attributed to subsidence driven by glacial isostatic adjustment [GIA; (13)]

Buzzanga et al., 2023

Even if we accept the acceleration claim, 4.4 – 1.5 still takes us back to 2.9 mm/yr… The same rate it’s been since before the Confederacy fired on Fort Sumter.

However, a quick look at NOAA’s “Variations of 50-Year Relative Sea Level Trends” clearly demonstrates that the apparent recent acceleration is simply due to the well-documented, roughly 60-yr cycle (quasi-periodic fluctuation for the math nerds) in the rate of sea level rise.

This cycle is most likely related to the Atlantic Multi-decadal Oscillation (Gervais, 2016NCAR) and not to fossil fuel consumption.

Yes, I know… Correlation does not equal causation. However, without correlation, it’s rather difficult to move on to causation.

Then there’s Bergen Point, with the shortest record length, entirely within the current up-swing of the ~60-yr cycle.

I’m surprised they didn’t cite Bergen Point as evidence of accelerated sea level rise [/Sarc off]

So… Yes, there’s lots of evidence that massive sheets of ice once covered New York City and much of the Northern Hemisphere… But they melted… A long time ago… And that’s a good thing. However, those ice sheets will almost certainly return at some point in the geologically near future. And that will be a very bad thing and far more catastrophic than 3 mm/yr of sea level rise:

Big Banks Quietly Prepare for Catastrophic Warming

Morgan Stanley, JPMorgan and an international banking group have quietly concluded that climate change will likely exceed the Paris Agreement’s 2 degree C goal and are examining how to maintain profits

By Corbin Hiar & E&E News

CLIMATEWIRE | Top Wall Street institutions are preparing for a severe future of global warming that blows past the temperature limits agreed to by more than 190 nations a decade ago, industry documents show.

The big banks’ acknowledgment that the world is likely to fail at preventing warming of more than 2 degrees Celsius above preindustrial levels is spelled out in obscure reports for clients, investors and trade association members.

Most were published after the reelection of President Donald Trump, who is seeking to repeal federal policies that support clean energy while turbocharging the production of oil, gas and coal — the main sources of global warming.

Figure 14. Life Expectancy: Our World in Data, Energy Consumption: Bjorn Lomborg, 2020 and CO2
(Wood for TreesMacFarling Meure et al., 2006)

Cue “correlation is not causation”… Allow myself to repeat myself… From 1800 to 1900, per capita energy consumption, primarily from biomass, remained relatively flat; as did the average life expectancy. From 1900 to 1978, per capita energy consumption roughly tripled with the rapid growth in fossil fuel production (coal, oil & gas). This was accompanied by a doubling of average life expectancy. While I can’t say that fossil fuels caused the increase in life expectancy, I can unequivocally state that everything that enabled the increase in life expectancy wouldn’t have existed or happened without fossil fuels, particularly petroleum.

Our modern society would not exist without fossil fuels and it would collapse in a heartbeat if fossil fuels were made unavailable and/or unaffordable. One of the coolest things about being a petroleum geologist, is that I can give thanks for fossil fuels and say “you’re welcome” in the same sentence.
