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

YOU’RE FIRED at last! Katie Hopkins is sacked by LBC after “final solution” tweet

She may have avoided a firing on The Apprentice, but she couldn't get out of this one.

Remember when Katie Hopkins wasn't a notorious radical hate preacher and was just that mean lady on The Apprentice who resigned from the show?

Well, let's cast our minds back to that time, in the heady days of 2006, when the nation sighed in frustration as the grand high angry bear Alan Sugar was denied his chance to point at her and growl "You're Fired!"

For we have at last been given what we have been waiting for over a decade.

Katie Hopkins has, finally, been fired.

OK, apparently it was mutual. She and the radio station that employs her for realtime weekly bile spews a live show, LBC, have parted ways:

According to the BBC's media editor, there were "cheers and applause" in the LBC newsroom when the decision was announced.

This follows Hopkins tweeting (and then deleting) that there needed to be a "final solution" following the Manchester terrorist attack. It seems LBC has found its own solution to the backlash against Hopkins.

I'm a mole, innit.
