As the G20 talks came to and end today in Pittsburgh it became clear to all of us here that industrialised countries have failed to realise the magnitude of the climate crisis.

Following inspirational speeches - in New York where leaders sounded the climate alarm - we were hoping that Heads of State would agree to put the money on the table that's needed for developing countries to mitigate and adapt to climate change in addition to to protecting their forests (vital carbon sinks). But they have hit the snooze button instead.

Climate financing is a key sealing a fair, ambitious and binding deal in Copenhagen this December. The lack of momentum here in Pittsburgh is quite a let down for the Greenpeace team here. And while we welcome the progress that has come out of this week - like the agreement to phase out fossil fuel subsidies - we're left staring at a gaping void between what's needed to avert climate catastrophe and what the industrialised countries are actually offering - despite their impressive rhetoric.

World leaders have finally realised that we're in a hole and they clearly understand the need to stop digging - but they need to agree when to put down their shovels. China and Japan have made some positive statements but key countries like Germany, France and the US are lagging far behind. If world leaders can't lead on climate - they should at least follow.

Inaction is unacceptable. It's time world leaders heard from all of us.
