Earthrise to Earthset: how the planet’s climate has changed since the photo that inspired the environmental movement
The global climate has changed drastically over the course of the 58 years that separate these two photographs of planet Earth.

If you're wondering what is causing the extreme heat over SE Australia at the moment, don't miss @weathermanbarnes.bsky.social's excellent explainer on substack. weathermanbarnes.substack.com/p/is-blockin...

Is "blocking" causing the incoming heatwave in Australia?
Australia is set to scorch this week, with the majority of southern Australia under heatwave conditions.

I'm excited to announce the official Nullschool app is here! earth.nullschool.net on mobile browsers works fine, but the app is nicer. Full screen display, persistence across sessions, text size that matches device settings. Even landscape works well. And, like the website: no ads! Links below ⬇️

One of our motivations for writing this was a prevalent misconception that blocking systems are becoming more common. They aren’t. They’re projected to become less frequent. However, the hot and dry spring is consistent with climate change. @ncas-uk.bsky.social @uniofstandrews.bsky.social

New paper on European blocking just out: rmets.onlinelibrary.wiley.com/doi/full/10.... Quite surprising - we looked at how blocking depends on physical parameters in a model and found very few sensitivities - only to convection in summer and to drag in winter. @cfmcswede.bsky.social

Hi all! A few weeks ago I realised I was sick of twitter, but to give it one last chance I thought I should wait until the European blocking ends. Oh well... 😉
