Met Office forecasts a supercomputer embarrassment

A new £33m machine purchased to calculate how climate change will affect Britain, has a giant carbon footprint of its own

For the Met Office the forecast is considerable embarrassment. It has spent £33m on a new supercomputer to calculate how climate change will affect Britain – only to find the new machine has a giant carbon footprint of its own.

“The new supercomputer, which will become operational later this year, will emit 14,400 tonnes of CO2 a year,” said Dave Britton, the Met Office's chief press officer. This is equivalent to the CO2 emitted by 2,400 homes – generating an average of six tonnes each a year.

The Met Office recently published some of its most drastic predictions for future climate change. It warned: “If no action is taken to curb global warming temperatures are likely to rise by 5.5ºC and could rise as much as 7ºC above pre-industrial levels by 2100. Early and rapid reductions in CO2 emissions are required to avoid significant impacts of climate change.”

However, when it came to buying a new supercomputer, the Met Office decided not to heed its own warnings. The ironic problem was that it needed the extra computing power to improve the accuracy of its own climate predictions as well as its short-term weather forecasting. The machine will also improve its ability to predict extreme events such as fierce localised storms, cloudbursts and so on.
