Re: US coasts sea level rise 10 to 12 inches by 2050

Closest one to our location, from end of WW II-

About 1 mm a year.

WHY do I not doubt this? Because it's natural, and it's based on real science. I recall from archeology classes at university finding chiton fossils were found well over 25 feet above MSL today. (Students today study Lady Gaga.)

The problem with climate alarmists is they only take in a very narrow segment of data and use man-manipulated models to predict catastrophe.

Let's look at real scientific data from climate.gov, NOAA, and NASA over the past few million years...
Natural forcings cannot explain the current warming.

Here is the climate.gov data https://www.climate.gov/climatedashboard

Here is 500 millions years of data.

But there is such data

A new analysis of 40 years’ worth of satellite data has shown we are as close to certain as we can be that global climate change is actively being caused by humans. No doubt some of you will read this and say, almost certain eh? Yes. The “gold standard” level of certainty in scientific evidence has officially been reached.

This “gold standard” is not thrown around lightly. It means evidence has reached a "five sigma" level of certainty – something particle physicists use to determine confidence in their findings, for example, the discovery of the Higgs boson in 2012. Here it means there is a 1-in-a-million chance that ongoing climate change is being caused by anything other than humans, or that we’re 99.99 percent sure it’s us.

We used to bring our power boat up to the dock at the Seaquarium on Virginia Key often over the last 20 years and no such condition existed, exists now or ever did. Sea level there has been consistent throughout that period.
There has been 0.3 meter (12 inches) rise in sea level at Virginia Keys since 1930.

Re: US coasts sea level rise 10 to 12 inches by 2050

Sea level rise is much more modest than false prognosticators have led us to believe. Al Gore’s worst case scenario fooled some for a time, but no more.

“I thought sea levels would have risen 20 feet by now thanks to the melting of either West Antarctica or Greenland,” wrote Jasmin Guenette at HuffPost.

Al Gore claimed that this would happen in the ‘near future,’ but thankfully, we’ve been spared so far. In fact, sea levels seem to be rising at maybe three millimetres per year. Twenty feet is over six thousand millimetres, so at this rate, we wouldn’t even be halfway by the year 3017.



1970 “If present trends continue, the world will be about four degrees colder for the global mean temperature in 1990, but 11 degrees colder by the year 2000,” claimed ecology professor Kenneth E.F. Watt at the University of California in 1970. “This is about twice what it would take to put us in an ice age.”

1971 Stanford University professor Paul Ehrlich, who is perhaps best known for his 1968 book The Population Bomb, in a speech at the British Institute for Biology. “By the year 2000 the United Kingdom will be simply a small group of impoverished islands, inhabited by some 70 million hungry people,” he claimed. “If I were a gambler, I would take even money that England will not exist in the year 2000 and give ten to one that the life of the average Briton would be of distinctly lower quality than it is today.”

2005, the United Nations Environment Programme (UNEP) warned that imminent sea-level rises, increased hurricanes, and desertification caused by “man-made global warming” would lead to massive population disruptions. In a handy map, the organization highlighted areas that were supposed to be particularly vulnerable in terms of producing “climate refugees.” Especially at risk were regions such as the Caribbean and low-lying Pacific islands, along with coastal areas.

The 2005 UNEP predictions claimed that, by 2010, some 50 million “climate refugees” would be frantically fleeing from those regions of the globe. However, not only did the areas in question fail to produce a single “climate refugee,” by 2010, population levels for those regions were actually still soaring. In many cases, the areas that were supposed to be producing waves of “climate refugees” and becoming uninhabitable turned out to be some of the fastest-growing places on Earth.

In 2007, 2008, and 2009, Al Gore, the high priest for a movement described by critics as the “climate cult,” publicly warned that the North Pole would be “ice-free” in the summer by around 2013 because of alleged “man-made global warming.” Contrary to the predictions by Gore and fellow alarmists, satellite data showed that Arctic ice volume as of summer of 2013 had actually expanded more than 50 percent over 2012 levels. In fact, during October 2013, sea-ice levels grew at the fastest pace since records began in 1979.

I totally agree,Al gore claimed in the seventies that the polar caps would be gone by the year 2000!

Alex Harris, Miami Herald - 2h ago

https://www.msn.com/en-us/weather/to...cid=uxbndlbing

As attention and urgency ramp up around the world over the looming dangers of climate change, a major new federal report released on Tuesday offers a surprising forecast: It actually reduces the amount of sea level rise the world is expected to see as the Earth warms.

For South Florida, the region with the most coastal real estate at risk, the sobering prediction is that the sea will continue to rise — about 11 inches by 2040 — but the latest forecast is markedly less than atmospheric modeling runs produced just five years ago. That previous forecast called for 17 inches by 2040, a level likely to produce regular and damaging tidal flooding in low-lying areas from Key West to Palm Beach County and beyond.



https://oceanservice.noaa.gov/hazard...ch-report.html

The Next 30 Years

Sea level along the U.S. coastline is projected to rise, on average, 10 - 12 inches (0.25 - 0.30 meters) in the next 30 years (2020 - 2050), which will be as much as the rise measured over the last 100 years (1920 - 2020). Sea level rise will vary regionally along U.S. coasts because of changes in both land and ocean height.

Breaking it Down:

Rise in the next three decades is anticipated to be, on average: 10 - 14 inches (0.25 - 0.35 meters) for the East coast; 14 - 18 inches (0.35 - 0.45 meters) for the Gulf coast; 4 - 8 inches (0.1 - 0.2 meters) for the West coast; 8 - 10 inches (0.2 - 0.25 meters) for the Caribbean; 6 - 8 inches (0.15 - 0.2 meters) for the Hawaiian Islands; and 8 - 10 inches (0.2 - 0.25 meters) for northern Alaska.

This report provides greater confidence in estimates of sea level rise out to 2050 than the previous 2017 report because of advances in sea level science, as captured in the Intergovernmental Panel on Climate Change’s Sixth Assessment Report, and the use of multiple lines of evidence: both the trends in the amount of relative sea level rise already observed and the models of future sea level rise closely match one another in the next 30 years.
Sydney Australia has had 3mm 1/8" per year in the last 40 years when the most C02 was introduced in the atmosphere. 120mm and the east coast of Australia (Sydney) is sinking due to continental drift.
Expect many more outrageous claims from the LOONY LEFTISTS

Re: US coasts sea level rise 10 to 12 inches by 2050

I sense (and share) a lot of skepticism about the climate narrative in general. "Follow the money" is a good rule of thumb. Who gains by promoting this narrative? The narrative is strongly anti-capitalist, and argues for bigger and more intrusive government with consequent loss of personal freedom. Funny how the climate narrative will make its promoters rich and powerful, isn't it?

Re: US coasts sea level rise 10 to 12 inches by 2050

I always find it odd that the wealthy and influential fail to divest themselves of their waterfront mansions while promoting doom and gloom to the hoi polloi. Are they perhaps throwing themselves on the proverbial grenade to protect the unwashed masses?

Re: US coasts sea level rise 10 to 12 inches by 2050

If/when polar ice caps melt the tectonic plates underneath being relieved of the immense weight above tend to rise. Which process tends to negate any sea level rise due to the ice melting. That would've been obvious to any 6th grader if the schools taught real sciences instead of CRT, wokism, gender theories and other such nonsense.

trump said it rises 1 millimeter in 300 years. So even he thinks the sea level is rising

Re: US coasts sea level rise 10 to 12 inches by 2050

Weird goings on up north last summer:

Quote:
For three days this month, 7 billion tonnes of rain fell across Greenland — the largest amount since records began in 1950. It’s also the first time since then that rain, not snow, fell on Greenland’s highest peak.

This is alarming. Greenland’s ice sheet is the second largest on the planet (after Antarctica) and any rain falling on its surface accelerates melting. By August 15, the amount of ice lost was seven times greater than is normal for mid-August.

Re: US coasts sea level rise 10 to 12 inches by 2050

Sea level rise - just a few examples
Alaska
https://e360.yale.edu/features/sea_l...maref_kivalina
Miami Beach
https://www.nrc.gov/docs/ML1601/ML16015A344.pdf Miami
Like many low-lying coastal cities around the world, Miami is threatened by rising seas. Whether the majority of the cause is anthropogenic or natural, the end result is
indisputable: sea level is rising and it is due to climate change. It is not a political issue, nor does it matter if someone believes in it or not
The North Pole
https://www.activesustainability.com...in=01833301559
Islands in the Pacific
https://www.theguardian.com/environm...climate-change
Glaciers (how will we rename Glacier National Park?)
https://www.worldwildlife.org/pages/...ea-ice-melting

On you own find out what's happening in Greenland and Siberia for just two more examples.

Science doesn't care what you believe in.

Just a small part of what's happening globally. Water water everwhere causing some folks not to think. Heads in the sand hard to retrieve once that sand becomes saturated.
