1/ When analysing the actions of Shi Zhengli, Peter Daszak, Kristian Andersen and others who insisted on shutting down doubts about the lab leak origin of SARS-CoV-2 in Jan and Feb 2020, it's worth remembering that at that stage it looked likely to be a minor Chinese epidemic.
2/ Almost nobody expected that millions would die, the entire world would be convulsed and therefore that every detailed action by scientists would later come under intense scrutiny.
3/ Thus you might expect to get away with publishing the genome of a bat virus without mentioning its origin, or the fact that you are renaming it without saying so, or the fact that three people died of a mystery viral pneumonia caught at the site.
4/ Likewise there would have seemed little risk at the time in insisting that an outbreak of a bat-derived virus in a city with the biggest bat-virus research lab did not merit further questioning.
5/ And it would have seemed sensible to suppress your own doubts about the natural nature of the genome of the virus lest it hand ammunition to the critics of virology laboratories.
6/ After all, it was far more important to undermine a blustering buffoon of a president than to get at the truth, even if it meant supporting the agenda of a totalitarian autocrat of a president.
7/ This is not to argue that the virus definitely came from a lab, but to understand the motives of those who insisted -- rather hamfistedly -- on prematurely ruling out that possibility at a time when it looked like a story that might last only a few weeks.

Thread: About 20 years ago I was invited to give the Prince Philip lecture at the Royal Society of Arts. I chose "reasons for environmental optimism" as my topic.

At the end, Prince Philip chaired a lively question session...
1/6
A man from Greenpeace put up his hand: "There's so much wrong with this lecture that I don't know where to start."

"Well, you've only got one minute, I'm afraid", said Prince Philip to a ripple of laughter.

The man then made his points for about 2 minutes, uninterrupted.
2/6
The next day a journalist from a big newspaper called me and said:

"We're running a story about how Prince Philip was very rude to a man from Greenpeace at a lecture at the RSA yesterday. Apparently, you were there. Can you confirm this?"

Thread on the new strain of SARS2 in the UK.

It's more than just a single mutation: 14 non-synonymous changes and several deletions.

virological.org/t/preliminary-…

1/5
It was first detected in Kent on 20 September.

"As of 15th December, there are 1623 genomes in the B.1.1.7 lineage. Of these 519 were sampled in Greater London, 555 in Kent, 545 in other regions of the UK including both Scotland and Wales, and 4 in other countries."

2/5
"The accrual of 14 lineage-specific amino acid replacements prior to its detection is, to date, unprecedented in the global virus genomic data for the COVID-19 pandemic...may have resulted, at least in part, from virus evolution with a chronically-infected individual."

Thread on the origin on the virus.

Many media outlets including the @thesundaytimes are speculating about whether the virus leaked from the Institute of Virology in Wuhan (WIV). Please note this is almost certainly the wrong lab to look at.

Although WIV is where the “bat woman” Shi Zhengli worked,

and although she initially worried about a leak from her lab,

Thread. 1. As Natural England bans crow control at the behest of @ChrisGPackham, remember why curlews thrive mainly in the North Pennines. Controlled experiments showed that their success at fledging young went from 15% without predator control to 51% with predator control.
2. Curlews are declining all over Eurasia. Two species of curlew have already gone extinct: Eskimo curlew and probably the slender-billed. This vulnerability is because they are large, slow-breeding waders that rarely lay eggs before they are 3 years old.
3. The British Isles is the breeding heartland of the “common” curlew with nearly 30% of the world population nesting here. But they are now v scarce in Ireland and Southern England and rare even in some upland areas of the Lake District and much of Wales.

Thread:

This is shocking. @lorddeben often accuses others of vested interests, but has been paid by green energy clients w/out declaring them while chairing the govt’s Climate Change Committee and pushing for policies relevant to those clients. 1.

dailymail.co.uk/news/article-6…
Code of conduct says to declare 'any private interests which may, or may be perceived to, conflict with your public duties'. @lorddeben’s wholly owned business Sancroft took money from biomass energy firm Drax while his committee was writing a report on biomass. 2.
Exeter university academic warned @lorddeben in 2015 that payments from green energy fund Temporis Capital were a 'clearly unethical' conflict of interest which would cause 'embarrassment' if made public. He ignored this and his firm got a further £37,000 from Temporis. 3.
