Fulfilling day @wmo-global.bsky.social congress including a reception at the UK mission to share the work we did on the Parliamentarians’ Guide to climate change and later hearing Secretary General Guterres recognise that WMO has been at the forefront of the fight for science and truth

Fantastic! My dad used to bring home that folding perforated paper for me to draw on. But what pray is the basin thing in the foreground?

Walking #ByTheSea for #WildflowerHour. All these were from Berry Head/Brixham. A brisk wind made focus challenging. #WildflowerID welcome on the second photo which I think is tall melilot but could easily be wrong

Oh my goodness! We’ve been discussing using gracehopper chips in our next supercomputer but I didn’t know! Respect!
Grace Hopper was an American computer scientist and United States Navy rear admiral. She was a pioneer of computer programming who was the first to devise the theory of machine-independent programming languages.

The Met Office uses observations from land, sea, atmosphere and space. Here’s one way we are addressing the relative sparsity of ocean observations 🧪
Our marine observations are vital for weather, climate, and research.

Now, ocean robots like Oshen’s C-Stars can independently sail for months, boosting ocean data alongside satellites and buoys.

See how the Met Office supports this innovation 👇
Are ocean robots the next big thing for climate monitoring?
With climate data more important than ever, is there a way to maximise marine data collection, gathering even more information from all oceans?

Great thread from Ed looking at how the Met Office data series for UK temperature stacks up against other reliable but independent measurements. Spoiler alert: very well indeed 🧪
Monitoring changes in UK temperature

To (almost) no-one’s surprise, multiple sources of data agree on the long-term trends in UK temperatures.

Every blessing to the wonderful Dame Sarah Mullally as she takes up this special responsibility. We are lucky to have her www.bbc.com/news/article...
Sarah Mullally named as new Archbishop of Canterbury
She becomes the first female leader of the Church of England, replacing Justin Welby who resigned over his handling of a safeguarding scandal.

One of those “Doh! Why didn’t we think of it earlier?” moments
Vertical rows are the agrivoltaic winner!

“The vertical panels produce slightly less electricity—but with higher value, as generation peaks coincide with morning and late afternoon demand…The crops don't seem to mind the presence of solar panels and they like the wind protection they provide.”
Double harvest: Vertical solar panels and crops thrive side by side
Imagine a field where solar panels and crops coexist—with no trade-off. It sounds like science fiction, but that's precisely what researchers from Aarhus University have now documented in a full-scale...

No shortage of #SeedHeads for #WildflowerHour on my walk near Widecombe in #Dartmoor. I do think hops, top left, are some of the most beautiful and I was amazed that the very dry bluebells, bottom right, were just ready to spill their glossy black seeds. IDs in alt text. @bsbibotany.bsky.social
