With politicians jumping over one another to claim that they are steering the world back to economic recovery, there are still few indicators that this is actually the case. Or are there?
"In the past, mentions of the word 'recession' have been a useful indicator of the likelihood of the real thing," says the Economist magazine. "Could the same be true of a 'green-shoots' index and the likelihood of economic recovery?"
So there we have it. With the economy in chaos, and our rudderless leaders in a spin, at least we have one scientific indicator that everything is going to be alright.
