A few years old, but still a great summary of where we're at - from @KHayhoe
I saw a very similar thing a few years ago.
This is Mt Manaslu (8,163m), Nepal, on 24 Oct 2022.
There's nothing this tall east of Manaslu. The peak was unequivocally lit from below.
The shadow boundary moved down at a uniform rate, so the sun is rising, not approaching.

It's disappointing that @James_Hawke1 felt the need to block me for this.
I always strive to be polite and factual.
Hopefully one day he'll get a camera out and try this simple experiment for himself.

You could easily check for yourself that the moon behaves like a dark rock reflecting sunlight.
Just take a photo of rocks in bright sunlight, then one of the moon with the same camera settings.
This was my attempt:

It appears @PostNASA blocked me after I explained top-down occlusion.
The moon's orbital motion (which is eastwards) takes it through earth's shadow. So occlusion is top-down at moonset and bottom-up at moonrise.

Why?
The sun is moving downwards relative to the position of the earth and the moon so the shadow on the moon will follow.
You’re over thinking it…

Periodically, I see people suggesting that the planet Venus is hot because of pressure, not greenhouse gases - e.g. see quoted thread.
I've had a quick look at this. The attached 2 page document is a record of my deliberations.
I'm a strong believer in the need to decarbonise.
But perhaps we need to be honest about the fact that it's going to be a long hard slog.
Some useful numbers about the cost.
In a development that won't surprise many people, on Monday the BBC World At One #WATO aired some of the worst misinformation about the cost of renewables I have ever heard. A thread 🧵(1/n)

A good summary of the challenges posed by having lots of intermittent generation, and the importance of dispatchable low-carbon generation in the mix.

Easy! 1,330 km / 826 miles to the Alps in the e-Niro. No planning, just stopping on the motorway.
3x rapids:
France, 31 mins (lunch)
France, 19 mins (coffee & ice cream)
Germany, 57 mins (lunch)
2x charges at hotels
£142 in total (+ hotels, tolls, vignette)
Spritz time! 🇮🇹🍹

Informative threads on SARS-CoV-2 lineage from @SolidEvidence.
Thread 1 (1-24).
Thread 2 (25-48): xitter.cf/SolidEvidence/status/1…
Thread 3 (49-53): xitter.cf/SolidEvidence/status/1…
We are now officially into year 5 of the SARS-CoV-2 pandemic/endemic.
I gave a lecture to my virology class this Fall about the history of the pandemic through the lens of viral genotypes.
I thought I would share that lecture as a thread.
This is a long one.

The next year or two could be interesting (not necessarily in a good way).
An excellent overview of El Nino, record sea surface temperatures and the imminent heating of the planet.

Stunning!
On Friday, the sun put on a dazzling show for us. My friend @TheVastReaches and I worked hard over the last 5 days to produce this incredibly detailed 140 megapixel image to illustrate how wonderfully dynamic and beautiful our star can be. Make sure you zoom in!

Great thread, as ever, from @KHayhoe
Less than 20 years ago, the world was headed for a >4C warmer world by 2100. The amount of change that would occur under that much warming, that fast, was almost unimaginable and certainly unsurvivable for human civilization + a large percentage of the world's species. (thread)

@YouTube @TeamYouTube please get a grip and fix this. The algorithm clearly got this badly wrong.
Dr John Campbell's video on XS deaths in Australia now has over 1 million views on YouTube. My video showing why it's misinformation has been BANNED by YouTube. (see link below to watch video.) YouTube is either being malicious, incompetent, or lazy. 1/

I don't understand enough about the energy market (I really should!) to tell if this is practicable, but the idea sounds great!
Fao @RestIsPolitics @campbellclaret @RoryStewartUK
#EnergyCap
We can:
quickly, cheaply, simply & easily
cap the wholesale price of 60% of the UK's wholesale electricity
Here is how:

Thanks @dr_barrett great work. It might feel like an uphill battle (check out Brandolini's Law) but it all helps.
#vaccineswork
had the misfortune (via @fatemperor) to come across Dr Paul Alexander -apparently credentialed yet in single blog post demonstrates perfectly either a disconnect from rational thought or deliberate misinformation spreading of the #masspsychosis of the anti-Vax crew let’s examine
