Although it makes grim reading “If current rates of biodiversity loss continue, every critical ecosystem is on a pathway to collapse.” it’s good to see biodiversity loss being considered as the threat to our national security which it is. Response requires understanding 🧪

A fast moving coronal mass ejection (CME) means the northern lights may be visible overnight, and perhaps on Tuesday night too
The arrival time of the CME is uncertain, but aurora sightings are possible in northern Britain and perhaps in southern areas depending on cloud cover.

In other things I learned from @newnhamcollege.bsky.social alumnae magazine yesterday, folic acid and its benefits for healthy pregnancy was discovered by Newnhamite Dr Lucy Wills in the 1930s
California now requires corn masa flour to contain folic acid to reduce birth defects among Latinos. Public health officials have lauded these efforts, but some conservatives say it’s another form of government overreach.
California is adding a supplement to tortillas. RFK Jr. calls it ‘insanity’.

This is a great article. Really worth reading through. 🧪The global chart is one I often use when people quote 1976 at me. And yes I’m so old I can remember it!
What would the hottest UK day of 1976 look like today?
35.9°C back in 1976 would be 38-39°C now.
The hot extremes are warming faster than the average for the UK.

At the @metoffice.gov.uk we are very consistent in the language we use to convey certainty & uncertainty. But we also do social science research on what users think as we articulate or illustrate, for example, chance of rain or attribution of extreme events to climate change. The quiz is worth a go!
How likely is ‘likely’? Does ‘likely’ have a higher probability than ‘probable’? I put together a quick quiz so you can see how you interpret probability phrases, then see how you compare with others: probability.kucharski.io

There'll be several attempts at incursions of less cold air from the west/Atlantic in the days ahead
This could bring some disruptive snow/rain/wind in the process ... but with uncertainty in the details..

Thought I’d have a look at istheukhotrightnow.com Note these are anomalies from the 1992-2020 mean not absolute values, but with climate warming faster than 30 year averages can keep pace widespread cold anomalies are relatively infrequent.
