Great news just in from Poland, where work on the giant Jóźwin IIB open-cast pit and coal mine near Konin has been suspended. Following a legal challenge submitted last December by Greenpeace, a Polish court has ruled that there were problems with the environmental assessment process undertaken before work began on the site. Construction has now been halted while the process is reviewed.

This is a big victory - Jóźwin IIB was the site for our most recent Climate Rescue Station, set up last winter to remind delegates at the United Nations Climate Change Conference in nearby Poznań that tackling climate change and building new coal-fired power stations are fundamentally incompatible aspirations. It will be particularly well-received by many of the peaceful activists who were attacked by mine workers at the end of last year during the protests.

As the science of climate change gets increasingly urgent, the will of Europe's political leaders to act on the climate crisis seems to be weakening by the day.

The EU climate package was meant to herald a new and unprecedented level of ambition in tackling climate change. Compared to what the science dictates, we're still way, way off the mark. The deal suffered from destructive forces within the EU representing their own country's self interests at the expense of an EU-wide deal.

With the current climate talks now underway in Poznan, the Brazilian government has finally fulfilled a promise it made at the previous round of talks in Bali last year and set targets for reducing deforestation in the Amazon. It's great to see they finally have some targets to work towards (and it's been a long time coming) but as is often the way with these political initiatives, it all falls short of what's really needed.

As the climate negotiations rumble on at Poznan in Poland, down the road at the coal power plant a group of Greenpeace climbers have scaled 150 metres up the chimney stack to hang 'Quit coal' banners, while another group has blocked the main entrance gate.

One of the climbers is Will, one of the Kingsnorth Six who were recently acquitted on charges arising from a similar action at (where else?) Kingsnorth power station in Kent - in fact, Will is providing the photos from the top of the chimney.

Do you feel the media sometimes misses the point? Wish it was getting the urgency of climate change?

EU leaders - 20 years of broken promises...

On 11 December at Poznan in Poland, our governments will decide Europe's response to climate change for the next 12 years. Unless they agree to at least 30 per cent cuts in European greenhouse gas emissions by 2020, we'll have no chance of keeping global warming below 2°C and avoiding climate catastrophe.

So far there is still an utter lack of any kind of visionary leadership in these talks. There are still governments that repeatedly fail to grasp the urgency of the crisis. That's why we need to make ourselves heard, because the impacts of climate change are racing ahead of the scientific projections.

Peaceful protesters from the our Climate Rescue Station were attacked by mine workers today as they entered the vast Jóźwin IIB open pit mine near Konin in Poland. As they prepared to paint a huge "Stop" sign next to a giant excavator, the activists were assaulted and prevented from carrying out their peaceful protest. A journalist accompanying them was also beaten.

Greenpeace volunteers worked constantly over several days to build the domed Rescue Station.

As governments prepare for the next round of crucial climate talks this December in Poznan, Poland, we're making a few preparations of our own. Obviously, we'll be at the talks, pressuring governments to quit coal and work towards a meaningful deal to save the climate - but we also have plenty planned for the run up to the talks.

On the edge of a vast open pit coal mine in Konin, Poland, we've set up a Climate Rescue Station - a four storey high earth dome powered by renewable energy - to highlight the true cost of coal in the lead up to the negotiations. People from 15 countries will be staying at the station, telling the story of how coal (the single greatest threat to our climate) is affecting our planet.
