As politicians gather to discuss the future of our climate Greenpeace took dramatic action on land and at sea to kick start an energy revolution. In Poland activists carrying a banner reading “Quit Coal, Save the Climate” have scaled the 150 metre-high chimney of the Pątnów power plant.

It has been a year since governments in Bali pledged to nail down an agreement to save the climate by December 2009. That means they have one year left to agree on how to stop the climate crisis. This year’s UN meeting on Climate Change has just started in Poznan, Poland and we think it is about time for government leaders to stop the talking, get serious and start real negotiations.

Our activists have delivered a huge pile of coal to the doorstep of a hotel in Warsaw where coal companies and heavy industry together with at least 20 industry ministers are meeting just days ahead of the UN climate negotiations in Poland. The Polish government appears to be gathering forces to protect coal users and suppliers, in opposition to the EU climate package being discussed next week.

Shameless. Disastrous. The international body responsible for "managing" what's left of the Mediterranean and Eastern Atlantic bluefin tuna stocks has ignored scientific advice, the demands of Greenpeace supporters around the world, and the pleas of the governments of Brazil, Canada, Mexico, Norway, South Africa and the United States to save the fishery from collapse.

The latest edition of our Guide to Greener Electronics has revealed that very few firms are showing true climate leadership. Despite many green claims, major companies like Dell, Microsoft, Lenovo, LG, Samsung and Apple are failing to support the necessary levels of global cuts in emissions and make the absolute cuts in their own emissions that are required to tackle climate change.

European Environment Ministers were asked to agree on strict controls ensuring food safety today, by our activists in Brussels. A giant banner displaying a ‘scary’ genetically modified corn plant and bearing the slogan Stop GMOs’ was dropped from a building on Schuman square (at the quarter of European Commission and European Council buildings) as dozens GM maize caricatures were laid around the street - highlighting the risks posed by genetically modified organisms such as maize.

Peaceful protesters from the Greenpeace Climate Rescue Station were attacked by mine workers when they entered the vast Jóźwin IIB open pit mine. As the activists prepared to paint a huge "Stop" sign next to a giant excavator they were assaulted and prevented from carrying out their peaceful protest. A journalist accompanying the activists was beaten. Local people are also against the expansion of this mine, because it threatens their homes and livelihoods.

Sixty activists are at the Garoña nuclear power plant in Spain to demand that the Spanish government make good on their commitment to start phasing out nuclear power plants, starting now with the immediate closure of the Garoña power plant.

Our activists marked the departure of Japan's whaling fleet from the port of Innoshima with banners declaring "Whaling on Trial." The fleet had attempted to leave for the Southern Ocean Whale Sanctuary unnoticed, by canceling their traditional high-profile departure ceremony in Shimonoseki. Instead, the factory ship Nisshin Maru left with no fanfare, waved off only by the crew's families and whaling officials.

What does it take to get the governments responsible for the imminent collapse of the East Atlantic and Mediterranean bluefin tuna fishery to wake up and do something? What about a mock "Pirates of the Mediterranean" poster of the responsible minsters in Pirate gear in the Economist? How about more than 10,000 emails? OK, how about several tonnes of dead tuna fish heads dumped on the doorstep of the French Fisheries minister?

The Rainbow Warrior has been impounded and the captain arrested after it was boarded by the police three times over the weekend. The ship was part of a protest against the new coal fired power station that E.ON is building next to their existing climate changing coal plant. The Rainbow Warrior together with one of our other ships - the Beluga II - were blocking the coal port of Rotterdam to stop any coal ships from entering. After spending the day surrounded by police boats they were eventually forced to leave the coal port in the evening.

Our team at the Climate Rescue Station in Poland joined 400 local people who live close to an open coal mine for a mass demonstration. Seven mayors from villages and towns, which are facing destruction because of the mine's expansion, also attended.

Supported by the Rainbow Warrior, a hundred Greenpeace activists have occupied the construction site of the new E.ON coal fired power plant on the Maasvlakte in Rotterdam. The activists have halted construction and intend to stay until the coal plant is cancelled. The activists locked themselves onto strategic points at the site and occupied the building cranes.

Greenpeace Africa opened its first office in Johannesburg today, announcing a long-term commitment to building a strong presence in Africa dedicated to tackling the most urgent environmental problems facing the continent - climate change, deforestation and overfishing.

Activists have blocked the operations of another tanker bound for Europe stocked with crude palm oil. The tanker, the Isola Corallo, was supposed to load up today but activists onboard the Esperanza moved into its place alongside the harbour and prevented the Corallo from taking on palm oil.

Good news for the whales comes in threes. And then you get a dollop of extra. Asahi Shinbum, one of Japan's biggest newspapers, reports a victory in the whale wars: there will be a 20 percent reduction in the number of whales targeted in the Southern Ocean Whale Sanctuary hunt this year -- the first reduction since 1987.

Thirty of our activists have shut down a giant excavator in one of the largest lignite mines in the Czech Republic. We're calling on the Czech Republic to close this mine by 2012, commit to progressively decreasing their carbon emissions and to play a constructive role in the creation of effective climate policy.
