Ocean Acidification

Fishing for plankton is ridiculous.

Plankton is justifiably outraged.

In the ocean, plankton is food.

There are two types of plankton – tiny plants (phytoplankton) and tiny animals (zooplankton).

Zooplankton includes some eggs and larvae of things like fish and crabs, as well as some minute animals that feed on phytoplankton. That makes them the first link in any food chain, and the basis for all of the ocean’s food webs.

IPCC's global warning means it’s time to get serious about protecting our oceans

We know climate change is the biggest threat facing our planet, which is why it is Greenpeace’s priority campaign across the world. Today’s report by the Intergovernmental Panel on Climate Change (IPCC)’s highlights the enormous impacts and consequences climate change is having on our oceans. This must act as a wake-up call for everyone who depends on, or cares about our oceans and the vast array of life within them.

These are the most important messages from report - and they mean for our oceans.

Science in the arctic: deploying mescosms at 79°N

Janet Cotter, from Greenpeace's Science Unit is currently on board the Esperanza on the first leg of the Arctic Under Pressure expedition. The ship is currently in Ny-Ålesund in the arctic, where Janet has been helping seagulls from 'contributing' to ocean acidification research.

In my day job, I work as a scientist as Greenpeace's Research Laboratories in Exeter, which is part of the Greenpeace's Science Unit. We might not get do the banner hanging from bridges and all the dramatic stuff that other Greenpeace activists do, but we have an important role in the organisation.  We analyse samples from around the world in our laboratories, often looking for toxic contamination of soils, rivers and seas, or sampling foodstuffs for GM contamination.

Esperanza heads north to investigate ocean acidification

It's a long, long way from Germany to Svalbard, but the Esperanza has arrived at Ny Ålesund, just 1,231km from the North Pole, for the start of the Arctic Under Pressure expedition. Around 2,500 people and about 3,500 polar bears live in Svalbard, an archipelago set of islands 60 per cent covered by glaciers (that's about 36,500 sq km of ice!). We're very, very far north in a wild, wild place.

Acid test for the oceans

Ever wondered what this ocean acidification thing is? Wonder no longer, as this new animation from our international office explains everything you need to know in just over a minute. 

The basic upshot is that climate change is not just making the oceans warmer, it's also making them more acidic. It's only by a relatively small amount so you won't lose your toes if you go paddling, but the effects on the ocean's chemistry is dramatic. Most widely reported is the threat this poses to coral reefs - as the water becomes more acidic, the polyps aren't able to create the calcium carbonate skeletons which form the reefs.

The consequences travel up the food chain - watch the video to find out more.

If feeding fish to cows is the answer, somebody's asking the wrong question...

Sometimes, you are a bit dumbfounded by stories that make the news. Seriously, you couldn't make some of it up, could you? I couldn't let this one pass (so to speak) without comment.

Today's belter is the new study suggesting that feeding fish to cows will help climate change. Yes, you read that right. The theory is something like this – cows, which we farm for milk, meat and leather, produce methane. Most of this is by burping, not flatulence as the comics would prefer. Methane is a bad, nasty, evil greenhouse gas. And we want to cut those down, don't we?
