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

Who will win in Manchester Gorton?

Will Labour lose in Manchester Gorton?

The death of Gerald Kaufman will trigger a by-election in his Manchester Gorton seat, which has been Labour-held since 1935.

Coming so soon after the disappointing results in Copeland – where the seat was lost to the Tories – and Stoke – where the party lost vote share – some overly excitable commentators are talking up the possibility of an upset in the Manchester seat.

But Gorton is very different to Stoke-on-Trent and to Copeland. The Labour lead is 56 points, compared to 16.5 points in Stoke-on-Trent and 6.5 points in Copeland. (As I’ve written before and will doubtless write again, it’s much more instructive to talk about vote share rather than vote numbers in British elections. Most of the country tends to vote in the same way even if they vote at different volumes.)

That 47 per cent of the seat's residents come from a non-white background and that the Labour party holds every council seat in the constituency only adds to the party's strong position here. 

But that doesn’t mean that there is no interest to be had in the contest at all. That the seat voted heavily to remain in the European Union – around 65 per cent according to Chris Hanretty’s estimates – will provide a glimmer of hope to the Liberal Democrats that they can finish a strong second, as they did consistently from 1992 to 2010, before slumping to fifth in 2015.

How they do in second place will inform how jittery Labour MPs with smaller majorities and a history of Liberal Democrat activity are about Labour’s embrace of Brexit.

They also have a narrow chance of becoming competitive should Labour’s selection turn acrimonious. The seat has been in special measures since 2004, which means the selection will be run by the party’s national executive committee, though several local candidates are tipped to run, with Afzal Khan,  a local MEP, and Julie Reid, a local councillor, both expected to run for the vacant seats.

It’s highly unlikely but if the selection occurs in a way that irritates the local party or provokes serious local in-fighting, you can just about see how the Liberal Democrats give everyone a surprise. But it’s about as likely as the United States men landing on Mars any time soon – plausible, but far-fetched.
