That's great. Does it start with an earthquake then?

That's a result.....all the other gripes can take a back seat.

That's right it starts with an earthquake, followed by a plague, then a recession, then a depression, the permafrost melting destroying oil infrastructure causing massive oil leaks, the rise of the far right, Trump reelected, a race war, aliens, costal flooding, flares coming back into fashion, superduper missiles, me running out of wine, the amazon rainforest dying slowly, millions of climate refugees, ducks eating locusts (google it), drive through eye tests, more aliens, the death of truth.
I'm in a good mood tonight too

Wasn't really sure what thread to post this in (or how to embed a tweet). It seems ominous to me so seems right to put it in the apocalypse thread.

At least 20 Indian Army soldiers killed in a face-off with Chinese troops
At least 20 Indian soldiers have died at Galwan Valley, in Ladakh, in a face-off between Indian and Chinese soldiers, according to government sources. Chinese forces also suffered casualties, ANI reports.
Why are the two sides fighting?
- In certain areas on the border, India and China have different “perceptions” of the Line of Actual Control (LAC) - Both the armies try and patrol up to their LAC, often resulting in face-offs - Tensions have been running high on the border since reports of a scuffle between the soldiers at Pangong Tso (eastern Ladakh) and Naku la (in Sikkim) a few months back - Both the armies have since deployed a large number of soldiers and heavy military equipment along the LAC.

An experiment searching for signs of elusive dark matter has detected an unexplained signal.
Scientists working on the Xenon1T experiment have detected more activity within their detector than they would otherwise expect.
This "excess of events" could point to the existence of a previously undetected dark matter particle called an axion.
Dark matter comprises 85% of matter in the cosmos, but its nature is unknown.
Whatever it is, it does not reflect or emit detectable light, hence the name.
There are three potential explanations for the new signal from the Xenon1T experiment. Two require new physics to explain, while one of them is consistent with a hypothesised dark matter particle called a solar axion.
The findings have been published on the Arxiv pre-print server.
So far, scientists have only observed indirect evidence of dark matter. A definitive, direct detection of dark matter particles has yet to be made.
There are several theories to account for what that particle might be like. The most favoured one has been the WIMP, or Weakly Interacting Massive Particle.
Physicists working on the Xenon series of experiments have spent more than a decade hunting for signs of these WIMPs. But the search has been fruitless.
But Xenon1T, the most recent iteration was also sensitive to other candidate particles.
Background noise
The experiment was operated deep underground at the Gran Sasso facility in Italy, from 2016 to 2018.
Its detector was filled with 3.2 tonnes of ultra-pure liquefied xenon, two tonnes of which served as a "target" for interactions between the xenon atoms and other particles that were passing through.
When a particle crosses the target, it can generate tiny flashes of light and free electrons from a xenon atom.
Most of these interactions - also known as events - are with particles we already know about, such as muons, cosmic rays and neutrinos. This constitutes what scientists refer to as the background signal.

A potential signal from an undiscovered particle needs to be strong enough to rise above this background noise.
Scientists carefully estimated the number of background events in Xenon1T. They expected to see roughly 232, but the experiment instead saw 285 - an excess of 53 events.
One explanation could be a new, previously unconsidered source of background contamination, caused by the presence of tiny amounts of tritium in the Xenon1T detector.
It could also be due to neutrinos, trillions of which pass through your body, unhindered, every second. One explanation could be that the magnetic moment (a property of all particles) of neutrinos is larger than its value in the Standard Model, which categorises the elementary particles in physics.
New physics
This would be a strong hint that some other new physics is needed to explain it.
However, the excess is most consistent with a signal from solar axions, a very light as-yet undetected particle, which is also a dark matter candidate.
In statistical terms, the solar axion hypothesis has a significance of 3.5 sigma.
While this significance is fairly high, it is not large enough to conclude that axions exist. Five sigma is generally the accepted threshold for a discovery.
The significance of both the tritium and neutrino magnetic moment hypotheses corresponds to 3.2 sigma, meaning that they are also consistent with the data.
Scientists working on the Xenon collaboration are currently upgrading to a different iteration called XENONnT. With better data from this future version, they are confident they will soon find out whether the excess is a statistical fluke, a background contaminant, or something far more exciting.

Temperatures in the Arctic Circle are likely to have hit an all-time record on Saturday, reaching a scorching 38C (100F) in Verkhoyansk, a Siberian town.
The record still needs to be verified, but it appears to have been 18C higher than the average maximum daily temperature in June.
Hot summer weather is not uncommon in the Arctic Circle, but recent months have seen abnormally high temperatures.
The Arctic is believed to be warming twice as fast as the global average
