From Mongolia, the sandstorm gradually moved southward.

Dust/2
The conditions for dust storms (drought, destruction of ground cover & trees, very high winds) are linked to #ClimateChange and human destruction of the environment. MORE

Dust/3
Mongolia, in particular, has seen a steady increase over the last 20 years in both the frequency and severity of massive dust storms, blanketing much of northern China before ending up over the Pacific Ocean.

Dust/4
The dust is, of course, over & above the terrible winter air pollution caused by coal burning for heat.

So, let's take a little walk down memory lane on treatment of Chinese in the USA. In 1871 in Los Angeles, 10% of Chinatown was slaughtered in a single night.

It was the worst lynching in a single day of US history:

2/The Rock Springs massacre, Wyoming, September 2, 1885: White miners slaughtered Chinese men, accusing them of "stealing jobs". At least 28 were murdered and most Chinese homes were burned to the ground. en.wikipedia.org/wiki/Rock_Spri…
It led to tense diplomacy between US & China.

3/On May 6, 1882 Pres. Chester Arthur signed the Chinese Exclusion Act, prohibiting all immigration of Chinese laborers. On May 5, 1892 Congress passed the Geary Act, requiring all Chinese to carry a resident permit at all times, punishable by deportation or a year of hard labor.

ATTN, New Yorkers: There's a new type of #SARSCoV2 in town -- a mutant that may outwit our #COVID19 #vaccines.
Here's what we know so far:
1.) A @Caltech team has been screening viral samples from USA and noted a new mutant appeared in November in NYC, dubbing it B.1.526.
MORE
2/ The @Caltech team says B.1.526 variant is spreading fast in NYC, now ='ing 27.8% of all new infections.
This virus has 2 key mutations that may make it dangerous. Both, alter the spike proteins that protrude from #SARSCoV2 & attach to human cells.
MORE
biorxiv.org/content/10.110…
3/ One mutation in NY's B.1.526 variant form of #SARSCoV2 is E484K -- this is the mutation point that makes the so-called South African and Brazil variants capable of evading antibodies and rendering some of the #COVID19 #vaccines far less effective.

From doxs submitted to @US_FDA on b ehalf of the J&J #COVID19 #vaccine application, some highlights:
1.) Genomic sequencing of viruses found in South African clinical trials came up 94% B.1.351 variant. But the vax was 52% effective against mild disease & 73% anti-severe.
MORE
2.) Some of the clinical trials were done in Brazil, where 69% of viruses they sequences were mutant P.2 variants.
3.) Data coves nearly 40,000 volunteers, half receiving placebo or 1 dose vax, followed for a mean of 2 months.
MORE
4.) "#Vaccine efficacy (VE) against lab-conf'ed moderate to severe/critical #COVID19 across all geographic areas in which the trial was conducted was 66.9% [for] cases occurring at least 14 dys after vaccination & 66.1%
[for] cases occurring at least 28 dys after vax."

Today @DrMikeRyan -- who heads up @WHO #COVID19 response -- received Ireland's Trócaire’s Romero Award. His speech was extraordinary. Some is in the clip below. And in a thread, here are key transcriptions.
