Some good news.

London is meeting legal limits for toxic NO2 pollution for the first time – almost 200 years earlier than predicted – following the Mayor’s "world leading air pollution policies," City Hall announces.

The Ultra Low Emissions Zone - and similar policies - really do work.

Many people feel overwhelmed with the number of potential climate solutions, and are not quite sure what to focus on.

@projectdrawdown.bsky.social has always been at helping people navigate the minefield.

Their new explorer is really cool, and helps to make things clearer: drawdown.org/explorer

Drawdown® Explorer

We know what we need to do: stop climate change as quickly as possible. Now, with the Drawdown Explorer, we know how to do it.

What impact do contrails from aviation have on global warming? Is there a cheap and easy way to get rid of them? There might be.

In the latest episode of Solving for Climate we speak with Ian McKay, founder of Orca Sciences about this and much more.

Thanks, Nick. I meant there is no universal vaccine that exists for many other infectious diseases — especially for first infection.

But agree that wasn't clear, and I've updated the article now to give a bit more context. Thanks for flagging.

I think Qdenga is also now recommended for 6-16yo.

Almost every question has a main chart in it. Of course, you’ll miss that with audio, but should still be able to get all of the main points (especially if you find audio easier to consume)

Oh, maybe that is because it's the paperback? That often comes out a bit later.

Oh no! I hope it is available again soon, wherever you are.

Thank you!

In the previous one, climate was just one chapter. This one is entirely focused on climate, and goes into much more detail on solutions, trade-offs, concerns that people have.

On my Substack I shared the list of 50 questions: www.sustainabilitybynumbers.com/p/clearing-t...

My new book — Clearing the Air — is published in the UK today

It was actually entirely coincidental from the publishers when they drafted some example covers (they didn't know about Sustainable Energy Without the Hot Air).

But then I thought the similarity was nice! I admired David MacKay a lot.

I really enjoy the wide-ranging (and often provocative) conversations Mark Lynas has on his @weplanetint.bsky.social podcast.

So I was very happy to join him again to talk more about climate change and what we do to fix it.

A decade of change.

In 2014, less than 4% of the world's electricity came from solar and wind. In 2024, this was 15%.

Here's how the distribution across countries has changed (+ shifted upwards) over those 10 years.

"A refreshingly pragmatic and undoomy book."

The Guardian just published a great review of @hannahritchie.bsky.social's new book 'Clearing the Air'.

The book will be out in 2 days.
