XR in Cornwall push a narrative that sea level could rise 70 metres then meltdown

Climate alarmists, Extinction Rebellion in Cornwall (XRiC), were pushing an article from Cornwall Live that suggested sea levels could rise 70 metres. It noted,

According to geologist Edmond Mathez of the American Museum of Natural History, if all the ice covering Antarctica, Greenland and in mountain glaciers around the world were to melt, the sea level would rise 70 metres and cover all coastal cities.”

When digging a bit deeper, it turns out a curator in the Department of Earth & Planetary Sciences answered this question from Hannah in Year 6.

Will the world ever be all underwater because of all the ice melting?

Mathez replied,

Dear Hannah,

Thank you for your question. The simple answer is no. The whole world will never be underwater. But our coastlines would be very different.

If all the ice covering Antarctica, Greenland, and in mountain glaciers around the world were to melt, sea level would rise about 70 meters (230 feet). The ocean would cover all the coastal cities. And land area would shrink significantly. But many cities, such as Denver, would survive.

However, all the ice is not going to melt. The Antarctic ice cap, where most of the ice exists, has survived much warmer times.

The concern is that portions of the Greenland and West Antarctic ice caps may disappear. We do not know how much or how quickly this could happen, because we do not know exactly how it will happen.

That’s because the ice doesn’t just melt. Ice actually flows down valleys like rivers of water . The problem is that we do not completely understand the factors that control how rapidly the ice flows and thus enters the ocean.

One way to approach the problem of not understanding the process is to study how sea level changed in the past. Earth is nearly as warm now as it was during the last interglacial period, about 125,000 years ago. At that time, sea level was 4 to 6 meters (13-20 feet) higher. It seems that this higher sea level was due to the melting Greenland and West Antarctic ice caps.

Perhaps a similar sea-level rise is our future. We don’t know. We also don’t know how rapidly sea level could rise. Will a 4-meter (13-foot) increase take 200, 500, or even 1,000 years? This is a question that a number of scientists are now trying to answer by studying how ice moves.

So Extinction Rebellion Cornwall (XRiC) took umbrage at CM’s insistence they were chasing pagan gods and hadn’t bothered to read beyond the Cornwall Live article. Some XRiC respondents came back with the idea some are suffering psychological issues by living in fear of these prophecies. CM pointed them toward the IPCC survey conducted in 2010 on the processes and procedures in the formulation of the climate bibles.

The collected answers to the questionnaire are contained in 678 pages.

Here are some direct quotes:

some of the lead authors…are clearly not qualified to be lead authors.” (p.16)

There are far too many politically correct appointments, so that developing country scientists are appointed who have insufficient scientific competence to do anything useful. This is reasonable if it is regarded as a learning experience, but in my chapter…we had half of the [lead authors] who were not competent.” (p. 138)

The whole process…[is] flawed by an excessive concern for geographical balance. All decisions are political before being scientific.” (p. 554)

Half of the authors are there for simply representing different parts of the world.” (p. 296)

Lest anyone think that people from less affluent countries were being unjustly stereotyped, the person whose comments appear on page 330 agrees:

The team members from the developing countries (including myself) were made to feel welcome and accepted as part of the team. In reality, we were out of our intellectual depth as meaningful contributors to the process.

CM also pointed out that the same Cornwall Live website posted,

The data shows the most expensive postcode in Cornwall is PL29 3, which covers Port Isaac, where an average price of £383,750 was recorded last year. This is up 10% compared to 2017.”

It would seem that the people of Cornwall aren’t fleeing the coastline in panic.

XRiC has deleted the post. Melting snowflakes?
