A Fire Rainbow over West Virginia
* Image Credit & Copyright: Christa Harbig
Explanation:
What's happening to this cloud? Ice crystals in a distant cirrus cloud are acting like little floating prisms. Known informally as a fire rainbow for its flame-like appearance, a circumhorizon arc appears parallel to the horizon. For a circumhorizontal arc to be visible, the Sun must be at least 58 degrees high in a sky where cirrus clouds present below -- in this case cirrus fibratus. The numerous, flat, hexagonal ice-crystals that compose the cirrus cloud must be aligned horizontally to properly refract sunlight in a collectively similar manner. Therefore, circumhorizontal arcs are somewhat unusual to see. The featured fire rainbow was photographed in 2021 near North Fork Mountain in West Virginia, USA.

‘Was this heatwave caused by climate change?’ – we’re asking the wrong question

I am sick of the #australian media playing #elnino down.
#Media around the world is reporting how bad it's going to be, and as it's record breaking it will most likely result in severe #weather disruption and perhaps even a #drought
But our media plays it down, it "might be a problem but we don't know".
If this was a low level event maybe. This won't miss us. #Physics #climatology
We're going to get slammed, but they know it will evoke talks of #climatechange and they don't want to hear it
Good morning tooters. It’s was a very cold frosty 🥶 morning today at -2c with a feels like of -4c & it certainly did feel that cold. Small black 🐀 💼 came & jumped on my bed during the night & curled into my back. Pretty good hot water bottle too. Larger 🐀 💼 stayed curled up in a corner of the lounge. As I’d been told to do when it’s really cold by the homeowner, I left the ducted heating on 16c all night just ticking over, so didn’t feel too cold when I got up at around 5.30am.
Just hanging around Chiltern today, might go & have a coffee out & a nice walk, but that’s it. My NZ friend heads down to Melbourne & the airport on the morning train tomorrow & I go home Sunday morning 😊.
I’ve been having some big thinks this morning - dangerous I know! I’ve been planning on a new ceiling fan in my bedroom for this coming summer as the old one doesn’t work very well anymore. Instead I’m going to call the local heating/cooling people to come out & give me a quote for a small split system for in there & to check out whether or not my old split system in the lounge needs upgrading or not. I want some information & things in place before the coming summer season hits.
Hope everyone has a fabulous #Friday stay nice & warm out there 🌻. #Weather #HouseSit #PetSit #Thinking #Planning
Happy #ThrowBackThursday !

Weather forecast for today is completely insane.
It's now 23° in the morning.
It's expected to reach 36° in 6 hours.
Then down to 22° 8 hours later (storm coming in).
And then 17° tomorrow morning.
I don't live in a desert. I live on the coast in Northern Europe. +13° rise in 6 hours followed by -19° drop in 12 hours is like nothing I ever heard of.

We need the rain here in Sandy, and the partial rainbow was a nice touch. #SandyUT #weather #WasatchFront
Scotland has enjoyed some dry and, for us, hot weather, with temps in the mid to high twenties. But the media habit of constantly referring to a UK heatwave when we’ve had wind and intermittent rain for the past week or so has irritated me. As usual, the UK doesn’t seem to extend to Scotland. So this morning, when the Guardian ran a piece asking how readers are being affected by the heatwave, I submitted a response saying “Hardly at all”.

Japan swelters through rising heat – in pictures https://www.theguardian.com/world/gallery/2026/jul/22/japan-swelters-through-rising-heat-in-pictures
The special #weather statement warning regarding possible heavy rains (100mm !) is still up, but the radar looks like the threat is somewhat diminished at this point.
A big system - Boston, NYC, Washington are all getting more of this than we are, I suspect.
phew, I was worried we'd have to go 24 hours without a severe storm with torrential rain, large hail, and damaging winds.
You can literally feel the air outside. It's thick and wet. It's going to get a few degrees hotter by mid afternoon. It's fucking miserable right now. We have the AC turned up to 78°F to conserve a little power while we're gone but all the fans are on moving air for pets so we're probably not saving much electricity.
It's currently 95°F/35°C with a feels like with humidity temperature of 117°F/47°C.
Apocalyptic video of forest fires in Spain.
Canada and France are burning too.
It's truly depressing, our politicians are busy helping orange shitler and Netanyahu destroy the world and act like global heating and climate catastrophe is not important enough to put all their energy and resources on.
Over 25000 people evacuated in France, Madrid is dangerously close to be burned and 100s of . millions of trees burned down across the globe.
As if our pollution wasn't enough,we are loosing our valuable trees too.

7am, piping-hot cup of mocha, opened the front door, very misty outside and drizzling rain but kind of nice as the sun rises (9.6c so not overly freezing), magpies are doing their morning warbling across the park next to my place.. will be staying in my dressing-gown & pjs for a while today I think..
Morning Mastodon 👋 ☕
