The programme failed to point out that scientists had now explained

the film failed to mention.

Well there's the answer to global warming then.

Another answer was mooted by some bod a few decades earlier when he
suggested seeding the oceans with iron.

Perhaps we aught to set up a petition so that the PM can send us all a
