Construction and commissioning is not the same as the plants actually being used to burn coal. Their coal plants are being used less and less - their capacity factor is dropping.

More like ‘borrowed’ than ‘robbed’! 😉

Very happy that so many people are borrowing the stripes concept to start important environmental conversations.

China remains way ahead in clean energy growth, adding more solar and wind capacity than the rest of the world combined.

The online version had an extra sentence. It is disappointing that the topic cut from the print edition was on the contribution of women observers:

"Although many rainfall recorders were men, there were also significant contributions from women, such as Lady Bayning in Norfolk in the 19th century."

Our paper on historic rainfall observers was discussed in The Times weather column this week, highlighting the role of the thousands of (often) volunteers who dedicated decades to taking detailed measurements of the weather.

Yep - remember that! I think I vaguely recall the satisfaction of seeing (from Adrian Simmons?) the brand new ERA-Interim agree with CRUTEM back in 2009/10 times.

Aside: Perhaps @copernicusecmwf.bsky.social should produce country-level averages for many different climate variables as a dataset from ERA5 or ERA5-Land? There may be 'political' reasons for not doing so but it would be valuable, especially for nations without extensive monitoring capabilities.

There are still some who try to dismiss weather station thermometer observations as being biased & unrepresentative of the true changes in temperature. The fact that the trends and variability match so well between these two datasets helps demonstrate that we are reliably measuring ongoing changes.

The @metoffice.gov.uk use weather station observations to reconstruct changes in UK average temperature since 1884.

@copernicusecmwf.bsky.social produce the ERA5 reanalysis which reconstructs global weather every hour back to 1950 using a weather forecast model.

Their estimates agree. Just sayin'.

There are still many volunteers who contribute manual daily rainfall observations and their sites are inspected to ensure reliable measurements. The proliferation of automatic weather stations is really helpful for real-time monitoring & nowcasting but perhaps not yet for long-term climate records?

🚨Our new paper introduces the #AirQualityStripes – a visual tool to show how outdoor air pollution (PM2.5) has changed in 🌍 cities since 1850. Inspired by the iconic #WarmingStripes. Led by @kirstypringle.bsky.social & @jimmcquaid.bsky.social

We have highlighted the critical role of ‘amateur’ volunteer weather observers whose dedicated observations made over decades for altruistic reasons are so invaluable to us now. There are still many volunteer observers taking daily climate observations today. Thank you to every one of these people.

If you’re a journalist writing about a certain piece of UK climate policy news this evening, please ask the Science Media Centre for the many reactions from expert climate scientists and then please include some of their quotes in your story. Thank you.

The Rainfall Observers

Over the past three centuries, thousands of people across the British & Irish Isles have recorded rainfall, often every day for decades. Here we recognise some of the individuals who made particularly important contributions.

The anthropogenic glacier collapse currently underway in the Alps has resulted in the disappearance of >1000 small glaciers! 😱🔥

The UK has quite a few long station series at hourly resolution, and the data is open, but not readily available via an API.

But e.g. @roostweather.bsky.social uses these data to build websites like this: istheukhotrightnow.com
Is the UK hot right now?
See live UK temperatures vs average, with detailed stats, daily trends, and historic comparisons from official UK sites.

🍩 What if climate looked like a donut? 🌍
Here’s a bunch of cities turned into a sweet dataviz experiment.

🟡 → comfy zone
🔴 → hot
🔵 → cold

Why a donut? Let me explain 👇
