Warm trousers

The Guardian rather undercuts its worthy new 10:10 carbon-cutting campaign with meaningless bastardised vergiage, as Ian Katz writes in his introduction:
With the exception of a small, saintly portion of the population, our response to global warming is a classic case of all mouth and no trousers.

See the paper's own delightfully illustrated style guide:
all mouth and trousers
not "all mouth and no trousers"
