This month's round-up of images from around the Greenpeace world.

The G8 leaders gather for the traditional 'family photo'. But on climate, there's little movement from the major economies.

It's not good news from Italy, as the G8 manage to sneak under the already low bar for action on climate set by the G20 meeting in London in April. A lack of near-term targets, fiddling the figures to buy time, a lack of detail on committing funds... It’s no wonder the less wealthy members of the Major Economies Forum – whose meeting ended today – walked away unhappy.

From the top of an Italian smokestack, Ben explains why we're telling G8 leaders to act now on the climate. We need strong leadership - what comes out of the G8 paves the wya for the upcoming Copenhange UN climate summit in December, which is the best moment of opportunity for averting dangerous climate change.

Day two on the coal occupation in Italy. In Marghera, near Venice, the occupation continues, with activists on the coal conveyor and the chimney painting 'G8: LEAD OR LOSE'. More activists are also occupying the cranes on the wharf, stopping a coal ship – the Bulk Brasil – from unloading its cargo from South Africa.

High above the Venice lagoon, Greenpeace demand strong climate leadership. from the G8.

Just as our tired activists in Italy were starting to settle in for a long night on top of the coal power stations yesterday, we got word that Greenpeace climbers in the US had rappelled down the face of Mount Rushmore with a banner that challenges Obama to show real leadership on climate change at the G8 this week.

Note - the live broadcast is no longer running.

We need to see real action from world leaders this year if we are going to save our climate. That's why over 100 Greenpeace activists from 15 countries occupied four coal-fired power stations across Italy today and they're demanding that the G8 Heads of State take decisive leadership on climate change. You can follow live updates from the Italy here.

And now our friends in the US have climbed Mount Rushmore and are challenging President Obama to be a leader on climate change, and they are broadcasting it live. The signal drops out occasionally, but when it works - wow. The park authorities have just reach the top of the monument.

The UK can set an example for the world by putting an end to new dirty coal-fired power plants. Tell Ed Miliband what you'll do if he consents a new dirty coal plant at Kingsnorth in Kent: The Big If

High above the Venice archipelago, activists demand strong climate action from the G8.

As the leaders of the world's most powerful nations arrived at the G8 Summit today, over 100 Greenpeace activists from around the world have occupied four coal-fired power stations across Italy, demanding the G8 Heads of State take leadership on climate change.

Listen to an interview with Greenpeace campaigner Ben Stewart, perched on a chimney above Venice:

When the G8 announced a 50 per cent cut in emissions by 2050, the obvious question that popped up was ‘50 per cent cut in comparison to when?' Even Yasuo Fukuda, the prime minister of Japan where the G8 is being hosted was thrown and answered the cuts would be in comparison to present levels. This is just an example of how ambiguous and indefinite the G8 is on tackling climate change.
