How Fast Are Oceans Rising? The Answer May Be In Century-Old Shipping Logs
NPR ^ | March 1, 2021 | Lauren Sommer

Off the coast of England, there's a tiny, wind-swept island with the remains of a lifeboat rescue station from the mid-1800s. The workers who once ran the station on Hilbre Island did something that, unbeknownst to them, has become crucial for understanding the future of a hotter climate: They recorded the tides.

The data, scrawled in long, handwritten ledgers, is just one example of the tens of thousands of pages of tidal measurements stored in archives around the world. Now, scientists and historians are racing to digitize them in an effort to understand how fast oceans are rising. The aging notebooks establish a historical baseline to compare with today's changing world.

Sea level rise is accelerating around the globe, likely to displace millions of people who live in coastal communities. Forecasts show between 3 and 6 feet of rise by the end of the century, or potentially more, depending on how much heat-trapping pollution humans emit.

Knowing exactly how much inundation to expect and how fast it's happening in each city can be tricky. Sea levels rise at different rates in different places due to the movement of the Earth's crust and ocean currents.

Long-term historical data, diligently tallied when the shipping industry was king, provide a window into these geologic processes and help improve the complex computer models scientists use to forecast the future. Those forecasts are crucial for helping cities prepare, whether it's building infrastructure to protect themselves or moving people out of harm's way.

Still, the vast majority of these historical records come from Europe and the U.S., leaving a glaring data gap in the Southern Hemisphere. That has researchers scouring archives of the Global South, including the ledgers of former colonial powers.

Obviously due to racism.

“Salt harvesting in this region began in the year 868!”

How can this be?

The article starts off "We don't know how fast the ocean is rising, we need lighthouse logs" then immediately jumps to "Sea level rise is accelerating around the globe, likely to displace millions of people who live in coastal communities."

I pity poor Barky getting displaced from his ocean-front digs on Martha's Vineyard. It's such a tragedy.


...researchers [are] scouring archives of the Global South, including the ledgers of former colonial powers.

How DARE they stoop so low as to use the ledgers of white supremacist, systemic racist, heteronormative, exploitive, land-raping "colonial powers" to further their cause? All those old ledgers should be cancelled and destroyed.

And the swindling continues.
We need to come up with a nasty nickname for the ‘research grant whores’.

Please don’t inject facts into the discussion.....

I live in the Atlanta area and bought real estate here in anticipation I will have an oceanfront home!

Oceans rise and fall.

Nations rise and fall.

Only one of these is caused by man.

It’s amazing how little people understand about our recent geologic history. For instance, most don’t realize that during the period you highlight, what is now known as Chicago was under a MILE of ice. The Great Lakes didn’t exist 25K-years ago. Instead, they were created when the ice from the last ice age retreated.

Think about how much colder it had to have been for a mile of ice to accumulate over most of what is now the Midwest. Our climate has changed significantly in what has been a blink of an eye, geologically...and it all had nothing to do with Mastedons and their SUVs.

Uh oh...I’m only FOUR miles from the shore and 125 feet above sea level. Now I’m worried. Thanks for ruining my day!

“Sea level rise is accelerating around the globe, likely to displace millions of people who live in coastal communities. Forecasts show between 3 and 6 feet of rise by the end of the century, or potentially more, depending on how much heat-trapping pollution humans emit.”

The assertion that sea level rise is accelerating is incorrect. The surface record shows a constant global sea level rise of about one inch per decade. The satellite derived products from Topex and Jason are noisy but validate the surface record, no acceleration.

The forecast for 2100 is deeply flawed and based on climate model predictions that assume a high sensitivity to rising CO2 and a strong water vapor feedback of 3 C. But empirical data show no increase in the amount of water vapor in the atmosphere (absolute humidity).

These climate alarmists are nothing more than peddlers of propaganda, a faith-based approach to atmospheric science. If a theory disagrees with experiment/observations, the theory is wrong.

“In that simple statement is the key to science. It doesn’t make any difference how beautiful your guess is, it doesn’t matter how smart you are who made the guess, or what his name is… If it disagrees with experiment, it’s wrong. That’s all there is to it.” Richard Feynman

Well, I’m hoping for the same here in central Kentucky, but I may have to wait a couple of weeks longer than you. :(

NPR just robbed a bunch of hysterical MSM reporters from future garbage reporting...

I had plenty of white global warming on my lawn in Maryland, too.

They did mention that as a contributing factor on the US East Coast.

Please don’t tempt me to pray for that. Right now, I would be almost, but not quite, willing to pray for such a thing. But I couldn’t, since I would be asking God to break a promise.

And, of course, since we’re in an interglacial period, the sea level was rising for thousands of years prior to 1900.

What BS. 8 inches versus 6 feet. Which will it be?

I don't see it being 6 feet, either, given that Global Warming is logarithmic - if CO2 rises at a constant rate, the temperature will rise more and more slowly as time goes on.

Yep, lots of salt water intrusion... /s

Yeah, Houston is that low and that flat!

I’d ban all ships, too, since some transported slaves in the past.

Ban chains and whips, while we’re at it.
