Our warming planet, set to music

This is what climate change sounds like.

I like data. Charts, graphs, tables, spreadsheets: anything which communicates information is good in my book (although infographics can get wearing, I'll admit). But I've not before heard music which does the same job.

Via Grist's Jess Zimmerman, I've now seen the work of University of Minnesota student Daniel Crawford, who has composed a piece of music based on our warming planet. Give it a listen. It's entrancing:

In the composition, each note represents a year from 1880 to 2012. The pitch is set so that the coldest year on record is equal to the lowest note on a cello, and each semitone is equal to "roughly 0.03˚C of planetary warming". The result is a haunting atonal composition – but also one which steadily rises in pitch, finishing three octaves above where it began. Similar projects normally set the data being played to a scale, which makes it easier to listen to (here's Pi in the key of C Major, for instance), but it's appropriate that something as catastrophic as climate change should be set to music which is fundamentally unsettling.

Not so unsettling as the line at the end, though:

Scientists predict the planet will warm by another 1.8°C (3.2°F) by the end of this century. This additional warming would produce a series of notes beyond the range of human hearing.

In case you want to play along at home, the sheet music is here and an MP3 of the song is here

Inside the progressive alliance that beat Zac Goldsmith in Richmond

Frantic phone calls, hundreds of volunteers, and Labour MPs constrained by their party. 

Politics for a progressive has been gloomy for a long time. On Thursday, in Richmond Park of all places, there was a ray of light. Progressive parties (at least some of them) and ordinary voters combined to beat Ukip, the Tories and their "hard Brexit, soft racist" candidate.

It didn’t happen by accident. Let's be clear, the Liberal Democrats do by-elections really well. Their activists flood in, and good luck to them. But Richmond Park was too big a mountain for even their focused efforts. No, the narrow win was also down to the fast growing idea of a progressive alliance. 

The progressive alliance is both a defensive and offensive move. It recognises the tactical weakness of progressives under first past the post – a system the Tories and their press know how to game. With progressive forces spilt between Labour, Liberal Democrats, Greens, the SNP, Plaid Cymru, the Women’s Equality Party and more – there is no choice but to co-operate, bring in proportional representation and then a whole new political world begins.

This move opens up the wider strategy – to end the domination of the City, and right-wing newspapers like the Mail, so Britain can have a real debate and make real choices about what sort of economy and society it wants. A pipedream? Well, maybe. But last night the fuse was lit in Richmond Park. The progressive alliance can work.

Months before the by-election, the pressure group for a progressive alliance that I chair, Compass, the Greens, and some Labour, Liberal Democrat and SNP MPs and activists, began considering this. The alternative after Brexit was staring into the void.

Then the Tory MP Zac Goldsmith stepped down over Heathrow. To be fair, he had pledged to do this, and we should have been better prepared. In the event, urgent behind-the-scenes calls were made between the Greens and the Liberal Democrats. Compass acted as the safe house. The Greens, wonderfully, clung onto democracy – the local party had to decide. And they decided to stand up for a new politics. Andree Frieze would have been the Green candidate, and enjoyed her moment in the autumn sun. She and her party turned it down for a greater good. So did the Women’s Equality Party.

Meanwhile, what about Labour? Last time, they came a distant third. Again the phones were hit and meetings held. There was growing support not to stand. But what would they get back from the Liberal Democrats, and what did the rules say about not standing? It was getting close to the wire. I spent an hour after midnight, in the freezing cold of Aberdeen, on the phone to a sympathetic Labour MP trying to work out what the party rule book said before the selection meeting.

At the meeting, I am told, a move was made from the floor not to select. The London regional official ruled it out of order and said a candidate would be imposed if they didn’t select. Some members walked out at this point. Where was the new kinder, gentler politics? Where was membership democracy? Fast forward to last night, and the Labour candidate got less votes than the party has members.

The idea of a progressive alliance in Richmond was then cemented in a draughty church hall on the first Tuesday of the campaign – the Unitarian Church of course. Within 48 hours notice, 200 local activist of all parties and none had come together to hear the case for a progressive alliance. Both the Greens and Compass produced literature to make the case for voting for the best-placed progressive candidate. The Liberal Democrats wove their by-election magic. And together we won.

It’s a small victory – but it shows what is possible. Labour is going to have to think very hard whether it wants to stay outside of this, when so many MPs and members see it as common sense. The lurch to the right has to be stopped – a progressive alliance, in which Labour is the biggest tent in the campsite, is the only hope.

In the New Year, the Progressive Alliance will be officially launched with a steering committee, website and activists tool-kit. There will also be a trained by-election hit squad, manifestos of ideas and alliances build locally and across civil society.

There are lots of problems that lie ahead - Labour tribalism, the 52 per cent versus the 48 per cent, Scottish independence and the rest. But there were lots of problems in Richmond Park, and we overcame them. And you know, working together felt good – it felt like the future. The Tories, Ukip and Arron Banks want a different future – a regressive alliance. We have to do better than them. On Thursday, we showed we could.

Could the progressive alliance be the start of the new politics we have all hoped for?
