Weather supercomputer used to predict climate change is one of Britain's worst polluters

Brilliant!  This computer was intended to save the environment, but environmentalists seemed unconcerned about it's carbon footprint (link).  

The Met Office has caused a storm of controversy after it was revealed their £30million supercomputer designed to predict climate change is one of Britain's worst polluters.

The massive machine - the UK's most powerful computer with a whopping 15 million megabytes of memory - was installed in the Met Office's headquarters in Exeter, Devon.

It is capable of 1,000 billion calculations every second to feed data to 400 scientists and uses 1.2 megawatts of energy to run - enough to power more than 1,000 homes.

Even better since the super computer has failed to accurately predict weather patterns for two years.  

It is the second time the Met Office has been criticised this year - after the machine famously helped predict a "BBQ summer" which turned out to be another wash-out. [emphasis added]

I guess you can't make roses out of garbage no matter how many calculations you do per second.
