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

The public like radical policies, but they aren't so keen on radical politicians

Around the world, support for genuinely revolutionary ideas is strong, but in the UK at least, there's less enthusiasm for the people promising them.

You’re probably a getting a little bored of the litany of talking head statistics: trust in elected officials, parliament, the justice system and even democracy itself has been falling steadily for years and is at record lows. Maybe you’ve seen that graph that shows how people born after 1980 are significantly less likely than those born in 1960 to think that living in a democracy is ‘essential’. You’ve possibly heard of the ‘Pasokification’ of the centre-left, so-named the collapse of the once dominant Greek social democratic party Pasok, a technique being aggressively pursued by other centre-left parties in Europe to great effect.    

And so, goes the logic, there is a great appetite for something different, something new. It’s true! The space into which Trump et al barged leaves plenty of room for others: Beppe Grillo in Italy, Spanish Podemos, Bernie Sanders, Jean Luc Melanchon, and many more to come.

In my new book Radicals I followed movements and ideas that in many cases make someone like Jeremy Corbyn seem positively pedestrian: people who want to dismantle the nation state entirely, use technology to live forever, go off grid. All these ideas are finding fertile ground with the frustrated, disillusioned, and idealistic. The challenges of coming down the line – forces of climate change, technological change, fiscal crunch, mass movements of people – will demand new types of political ideas. Radical, outsider thinking is back, and this does, in theory at least, offer a chink of light for Corbyn’s Labour.

Polling last week found pretty surprising levels of support for many of his ideas. A big tax on high earners, nationalising the railways, banning zero hours contracts and upping the minimum wage are all popular. Support for renewable energy is at an all-time high. According to a recent YouGov poll, Brits actually prefer socialism to capitalism, a sentiment most strongly held among younger people.

There are others ideas too, which Corbyn is probably less likely to go for. Stopping benefits entirely for people who refuse to accept an offer of employment is hugely popular, and in one recent poll over half of respondents would be happy with a total ban on all immigration for the next two years. Around half the public now consistently want marijuana legalised, a number that will surely swell as US states with licenced pot vendors start showing off their dazzling tax returns.

The BNP effect used to refer to the problem the far-right had with selling their ideas. Some of their policies were extremely popular with the public, until associated with the BNP. It seems as though the same problem is now afflicting the Labour brand. It’s not the radical ideas – there is now a genuine appetite for those who think differently – that’s the problem, it’s the person who’s tasked with delivering them, and not enough people think Corbyn can or should. The ideal politician for the UK today is quite possibly someone who is bold enough to have genuinely radical proposals and ideas, and yet appears extremely moderate, sensible and centrist in character and temperament. Perhaps some blend of Blair and Corbyn. Sounds like an oxymoron doesn’t it? But this is politics, 2017. Anything is possible.
