Is A New Age Of Pressure Upon Us? - 16

Pressure changes cause reactions

This Dredd Blog series, which hypothesizes that sea level change (SLC) can trigger geologic activity, began a decade or so ago (May 27, 2010), and has continued off and on since then (Is A New Age Of Pressure Upon Us?, 2, 3, 4, 5, 6, 7, 8, 9, 10,11, 12, 13, 14, 15).

A recent paper based upon thousands of years of prehistorical data offers some support for that hypothesis:

"The research finds that lower sea levels, which happen during ice ages, were linked to higher rates of eruption. The researchers believe this result likely holds true for other island volcanoes.

'The mechanism is quite simple,' says Dr Christopher Satow, senior lecturer in physical geography at Oxford Brookes University, UK, and lead author on the paper.

'Falling sea levels remove mass from the Earth’s crust, and the crust fractures as a result. These fractures allow magma to rise and feed eruptions at the surface.'"

(Cosmos Magazine). And conversely, the opposite mechanism is quite simple: "[Rising] sea levels [add] mass [to] the Earth’s crust, and the crust fractures as a result."

It is well known that volcanic activity and earthquakes can be related (USGS) or not (USGS).

The problem with trying to determine if SLC is a factor in any particular earthquake or volcanic event is that there are so many such events and the science is immature.

As it stands now, the evidence would likely have to be circumstantial or extrapolated because not much direct research is being done (NASA Busts The Ghost).

The IPCC Record on Global Warming Temperature Projections - 4

"The Earth is Cooling"

This is the fourth episode of this series (The IPCC Record on Global Warming Temperature Projections, 2, 3).

In previous posts of this series, and in other posts on the subject of IPCC reports, Dredd Blog bemoaned the lack of being able to grasp the real situation.

Dredd Blog advocated that the less-than-real rhetoric concerning global warming induced climate change should be dispensed with:

"The IPCC is a well known report, but fewer people know about another government climate change report required by federal law (Government Climate Change Report, 2, 3, 4, 5, 6, 7, 8, 9).

Today I want to discuss a common scientific error that has led us astray for a century (Dr. Mitrovica).

"The Earth is Burning"

That error makes its way into every climate change report which includes sea level change (at least every official report I know of).

For example, the promiscuous use of "global mean average sea level" (GMSL) is the error I am talking about (it's the mother of invention of "the bathtub model")."

(The IPCC Record on Global Warming Temperature Projections - 3). Well, here we are with a stark contrast with earlier versions.

Here we are with a link to the Sixth Report, which is beginning to tell it like it is (AR6 Climate Change 2021: The Physical Science Basis).

"Mr. Blue Sky" still metaphorically says there is "not a cloud in the sky" in the video below, while the reality seems closer to How To Enjoy The End Of Bad Choices.
