As I recall there was a massive landslide, but depending on the timing it was the coup de grâce. Mostly it was glacial melt water. London was under kilometers of ice at one point

What was the extent of ice cover across the UK during the last ice age ...
There is no permanent ice cover in the UK today. However, 20,000 years ago, it was a very different situation when most of the UK was covered by an expanded Arctic ice sheet. The ice was three kilometres thick in places. Large bodies of ice, called glaciers flowed slowly from highlands to lowland areas. The Earth's climate warmed around ...

Yup

Storegga Slide
The three Storegga Slides are amongst the largest known submarine landslides. They occurred at the edge of Norway's continental shelf in the Norwegian Sea, approximately 6225–6170 BCE.Wikipedia

Younger Dryas
The Younger Dryas, which occurred circa 12,900 to 11,700 years BP, was a return to glacial conditions which temporarily reversed the gradual climatic warming after the Last Glacial Maximum, which lasted from circa 27,000 to 20,000 years BP.Wikipedia

6225–6170 BCE would be 8248–8193 BP.

www.ceres-science.com: New study suggests global warming could be mostly an urban problem

A new study published in the scientific peer-reviewed journal, Climate, by 37 researchers from 18 countries suggests that current estimates of global warming are contaminated by urban warming biases.

The study also suggests that the solar activity estimates considered in the most recent reports by the UN’s Intergovernmental Panel on Climate Change (IPCC) likely underestimated the role of the Sun in global warming since the 19th century.

...some scientists have been concerned that the current global warming estimates may have been contaminated by urban heat island effects. In their latest report, the IPCC estimated that urban warming accounted for less than 10% of global warming. However, this new study suggests that urban warming might account for up to 40% of the warming since 1850.

Suppose which side you're on matters here as to whether or not thats real

[freebeard]

I see it the other way 'round. Somthing is either real or not (the Implicate Order), but which side to be on is an opinion.

Personally.... Runaway Greenhouse punctuated by a Vulcanic Winter.

[Piotrsko]

Data is data. How one interprets that scarce data is influenced by a laundry list of real and imagined processes mostly internally held.

Lots of congruent self reinforcing data is harder to imagine away. Do not see that data tipping point yet.

Vulcanic winter? Interesting turn of phrase.

They say that history doesn't repeat but rhymes. At Permalink #942 I mentioned tetrataenite, a mineral found in meteorites, consisted of iron and nickel structured at nano-scale. Powerfully magnetic without the rare earths normally required.

So now researchers are pursuing a metamaterial consisted of iron and oxygen.

phys.org: Nanoscale rust: The future of magnets?

Every motor we use needs a magnet. University of Manitoba researcher Rachel Nickel is studying how rust could make those magnets cheaper and easier to produce.

Her most recent paper, published in the journal Nano Letters, explores a unique type of iron oxide nanoparticle. This material has special magnetic and electric features that could make it useful. It even has potential as a permanent magnet, which we use in car and airplane motors.

What sets it apart from other magnets is that it's made from two of the most common elements found on earth: iron and oxygen. Right now, we use magnets made out of some of the rarest elements on the planet.

"The ability to produce magnets without rare earth elements is incredibly exciting," says Nickel. "Almost everything that we use that has a motor where we need to start a motion relies on a permanent magnet".

Researchers only started to understand this unique type of rust, called epsilon iron oxide, in the last 20 years.

Did you catch the coincidence?

I've been having Youtube withdrawals, so I went to visit Phys,org. and there's a lot that's news. But they have an nag screen on every page now, too. at least all they do is nag.... so far.

phys.org/: New noble-metal-free electrocatalyst decreases the energy required to generate hydrogen gas from water
Brown's Gas FTW.

A new electrocatalyst leverages enhanced electrochemical activity, reaction surface area and durability to improve the efficiency of hydrogen gas production via electrolysis.

Researchers from Center of Excellence for NaNo Energy & Catalysis Technology (CONNECT), Xiamen University in Malaysia synthesized and characterized an efficient and durable water electrocatalyst composed of the transition metal dichalcogenide tungsten disulfide (WS2), a two-dimensional material with semiconducting properties, that functions as an electron acceptor or donor in the electrolysis reaction.

The electrocatalyst, WS2/N-rGO/CC, is created on a carbon cloth (CC) that is bound to reduced graphene oxide (rGO), a two-dimensional lattice semiconductor, combined with a very small amount of nitrogen (N) to alter the properties of the reduced graphene oxide semiconductor. A hydrothermal reaction converts two-dimensional WS2 into microscopic, three-dimensional flower-like structures called nanoflowers that increase the surface area of the electrocatalyst to improve reaction efficiency.

Mars not a dead planet, in fact far from it.

So you can throw out your outdated books from the 1980s and earlier that say mars is a dead planet.
