Absolutely, let's focus our resources on putting a stop to the dangerous, unregulated experiment on the climate system that we've been running for more than 150 years. That's the only one for which we have empirical evidence of the consequences. There's no time or money to spare for distractions.

I don't have links to any recordings, but here's a link to an article in a local paper about a recent talk. You do need to sign up to their email newsletter to read it (but you can always unsubscribe later).

It's almost as if you've attended one of my public talks!
The outlook is challenging, but don't underestimate our capacity to make things even worse.

Closing your eyes when you're about to crash won't stop the crash happening.
The stupidity we're witnessing is off the scale.

There's nothing quite like a good old bit of false balance. We've been here before in relation to whether or not human actions are the main cause of recent climate change. The truth is that the overwhelming majority of scientists oppose these science fiction fantasies, for good reasons.

Indeed.

As you might expect from this, there's a lot of red and orange in this latest view of SST looking down from above the North Pole from Climate Reanalyzer. One area that's an exception is the "cold blob" in the North Atlantic, and that's not good news.

And there are processes that are still not well enough understood to be parameterised in models, such as tidal incursion into grounding zones, which could lead to even faster ice loss than current models show.

All the model projections I've seen from modellers involved in the International Thwaites Glacier Collaboration show continued rapid ice loss in the Amundsen Sea sector without further warming. Eventually the grounding zone retreats onto a more continuous retrograde slope and then MISI takes over.

I'd say recent results show it's already heading towards the tipping point even without any further warming. It may take decades to get there but it's on its way.

Meanwhile, in Cambridge this is what passes as a cycle lane along Grange Road, one of the main routes to the West Cambridge Science site.

Most people believe in the values of democracy, but those values are being assaulted by this administration every day.
Still, scientists should engage more publicly. And it would be great if the public realizes that science isn't just something nerds do, but the foundation of modern society. 2/2

I expressed a similar feeling a few days ago, but as a potential foreign collaborator it's not such a critical decision for me.

Have you heard about the water company that has no reservoirs and just pumps water out of a chalk aquifer as if it is an inexhaustible supply?

Pertinent questions are what assumptions have been made about future sea-level rise and what testing has been done to provide confidence that there will be no saline groundwater ingress?

For those interested, according to the Merlin app the birds heard on the recording include Robin, Blackcap, Song Thrush, Wood Pigeon and Chiffchaff.

We can't know for certain because the definition requires knowing what temperatures will be over the next 10 years. Nevertheless, I think the messaging needs to shift to limiting the overshoot, rather than avoiding reaching 1.5°C.

I can't agree with the final quote in the article, that 1.5°C is not inevitable. Given that average global temperatures in most months over the past two years have exceeded this level, there is an argument that we have already passed this threshold.

In order to achieve regeneration analogous to that in Kendall Square, investment should instead be directed to conurbations in Yorkshire, the northwest or West Midlands, where there are former industrial brownfield areas available for redevelopment.

The stark difference is that most of the Ox-Cam arc is far from being a derelict industrial wasteland. Much development will be on areas that are presently green fields and woodlands.

which was transformed, with considerable input from Harvard University and the Massachusetts Institute of Technology, from a derelict industrial wasteland into a thriving biomedical quarter."
