I came across the above bill board from Oxfam and felt it overstated it's case on "Man Made" Climate Change.
We have recently seen a reversal on one campaign via the advertising standards Ed Miliband's adverts banned for overstating climate change by Jonathan Leake, Environment Editor, The Sunday Times
The bill board heading reads:
"You might have read that the climate change talks are dead in the water"
"Bit of irony there for the thousands who'll be hit by floods"
