Ever notice that multiple‑choice quizzes often feel strangely predictable? I recently dug into why answers so often sit in the middle—and what this reveals about our deep, systematic difficulty with randomness. It’s more surprising than you might think. 🧵👇

A new all-electric double-decker Climate Stripes bus has started taking passengers around Reading today.

The bus shows the warming stripes for Reading back to the 1860s and will hopefully help start climate conversations amongst passengers.

#WeekendReading: Ouyang et al. on the Phanerozoic onset of large-scale continental weathering. It does lean on K/Al, which I am having some issues with, but a good amount of other proxies show up as well. 🧪⚒️

I really hope this works - great for the region and UK in general. Also a great advert for how Geology and Geologists can have a really positive impact on shaping our Green Future 🧪⚒️

Let's ask the question: How many times do the following people show up being named in the Epstein Files:

President Joe Biden: 0
President Barack Obama: 0
MN Governor Tim Walz: 0

President Donald Trump: 4,500

Does any Republican not see the problem?
People are struggling.

We need to lower bills, protect our NHS and rebuild our public services.

Found a startling comparison using real photographs of one reef over the decades.

Very effective illustration of what has happened to Florida's coral reefs in response to anthropogenic climate and environment change. The loss of this important ecosystem is all but complete - attempts to rescue it discussed here: www.pnas.org/doi/10.1073/... 🪸🧪🌊
When it rains, it now rains more.

For those experiencing the flooding in south-west England, it is worth remembering that rainfall in winter has increased by about 25% overall.

And, the rainfall has also become more intense: when it rains, it now rains more, increasing the risk of flooding.

Trump on NATO: "I've always said, will they be there if we ever needed them? That's really the ultimate test. I'm not sure of that. We've never needed them. They'll say they sent some troops to Afghanistan and this or that. And they did. They stayed a little back, off the front lines."
