While our leaders continue to talk about what's "politically possible," the world continues to warm and precious days go by. The latest science shows that runaway global warming is even closer than we feared. We can't continue to allow our leaders to sit back and play political games when our future is at stake.

That’s why on October 24th, Greenpeace is joining with 350.org and a broad coalition of groups to participate in an international day of action. Events are already planned in over 100 countries around the world. Some are big, some are small - but every single one of them is absolutely necessary.

In the latest step forward for our Amazon campaign which began with the publication of Slaughtering the Amazon, Bertin, the world's largest leather exporter, is finally doing the right thing and backing the call for a moratorium on buying cattle from farms responsible for Amazon deforestation.

Cat is up today in our spring blog relay - catch up on entries from other Greenpeace staff.

I'm a biologist. I have always been fascinated by the vast array of beautiful, crazy and weird life forms on this planet. I specialized for many years on the health of one of the most fascinating creatures - human beings. But now I work on the health of the oceans, without which the health of the entire planet is in dire trouble.

Like Emily, I joined Greenpeace as volunteer, coordinating and training local activists in London, while working full-time as a medical journal editor. I became a freelancer to have more flexibility to be an activist, and soon found work on a variety of Greenpeace projects with the active supporters unit, the publications team, and the toxics campaign. Then the oceans team urgently needed a researcher, and the next thing I knew I was writing briefings and heading out to sea on the Esperanza to try to stop seabass pair trawlers from catching and killing dolphins.

I made a small snowman in my garden today. I have to call it a small snowman since it really is small. And the snow is not good enough for making snowballs - which are the basic building block of any snowman's body. But it was still really fun. I couldn't remember how long it was since I had made a snowman or had so much fun. I am thankful for what was the first and probably the last snow this winter, although I have read that the government has plans to make it snow again because we are in the middle of a pretty serious drought in Beijing.

If we're to avert catastrophic climate change the world must quit coal. But the industry and the powerful forces which rely on it won't go down without a fight. Yesterday, in Warsaw, Greenpeace provided them with two reminders of why we all need to quit coal.

Latest updates from the impressive ProtectPlanetOcean web site provide convincing support for Greenpeace's long-held contention that marine reserves provide the best long-term solution to the problems of overfishing and pollution which threaten the world's marine ecosystems. In case you've forgotten marine reserves are protected areas, national parks at sea where no fishing or other extractive industries (such as oil, gas or gravel extraction) are permitted.

The site has pulled together studies of 124 marine reserves around the world - scientific peer-reviewed research published in academic journals - to provide a clear picture of what has happened where reserves have been established.

It's official; mankind is killing off our oceans far faster than previously thought. The first global-scale study of human impacts on marine ecosystems, published today in the flagship US journal Science, reveals a picture of widespread destruction with few if any areas remaining untouched.

The North Sea, once one of the most productive in the world, is now amongst the most degraded. Oil extraction, waste dumping and chemical pollution have all taken their toll, and relentless commercial fishing has pushed some fish stocks - such as cod - to the brink of collapse.

Which is why our ship Arctic Sunrise is once again heading out into the North Sea to campaign for the urgent creation of marine reserves - national parks at sea where marine life can get some respite from commercial exploitation.

Car manufacturers are trying to sabotage a new European climate law that would force them to improve the efficiency of their new vehicles. But there's time to act to make sure that Europe's cars are cleaner and greener in future.
