The eastern Pacific, from the Bering Sea to northern California, has been one of the world’s last remaining great fisheries. It’s a band of coastal ocean famous for its abundant salmon, cod, halibut and tuna but it’s also known for its bounty of crab of several varieties plus shellfish including scallops, clams, mussels and oysters.
Now a lot of that resource is at severe risk from our greenhouse gas emissions that are acidifying the ocean habitat. The acid levels in our waters have increased by 30% since the beginning of the Industrial Revolution. That’s the kiss of (Read more…)

Island Scallops is on the ropes. The company, which produces an astonishingly-good hybrid scallop, has just lost three years’ production to ocean acidification.
As we’ve pumped ever more CO2 into the atmosphere, our oceans have absorbed increasing amounts of it, in turn acidifying. The more acidic water attacks the calcium in corals, mollusc shells and so on. It’s been doing a job on Island Scallops’ production.
The disaster, which cost the company $10 million and could lead to its closure, is the latest vicious reminder of the submarine impacts of our fossil fuel–heavy energy appetites. As (Read more…)
All of us need to get a sense of what the world’s oceans mean to us, the role they play in our daily lives even if we live far inland in a place like Winnipeg, for example.
Here’s one to chew on. The oxygen in every second breath you take is supplied by the oceans. There, does that help connect you to our oceans, your oceans? Your life literally depends on them. That sure works for me.
We’ve tipped nature’s balance enough that we have caused the oceans to acidify at rates not seen in 300-million (Read more…)
I’ve been blogging about climate change since my conversion from being a climate change avoider to a climate activist/fossil fuel abolitionist in the fall of 2009. As a climate change avoider, I never watched An Inconvenient Truth; after all, it might be inconvenient to have to face my fear or be prodded into taking action. […]

This week on Earthgauge Radio, we’re talking about environmental health and ocean acidification. I have two interviews on the program today:
Dr. James Brophy, co-author of a groundbreaking new study demonstrating that women working in particular occupations have an increased risk of developing breast cancer, likely due to exposure to toxic chemicals and environmental pollutants Dr. Robert Rangeley of the World Wildlife Fund of Canada who will explain why the rapid acidification of the word’s oceans threatens many forms of marine life and may even endanger the oceanic food chain

Tomorrow on Earthgauge Radio, I am pleased to present a feature interview with Dr. James Brophy, who is the co-author of a groundbreaking new study demonstrating that women working in particular occupations have an increased risk of developing breast cancer. Their research found that women employed in the automotive plastics industry, for instance, were almost five times as likely to develop breast cancer, prior to menopause, as women in the control group. The research results have created quite a stir in the cancer research community and our discussion tomorrow is not to be missed!
We’ll also have an interview from

Anthropogenic (man-made) carbon dioxide is responsible for adding to global warming and triggering a host of attendant environmental problems. CO2 has also contributed to a dramatic spike in the acid levels of the oceans – an effect that has been cast as the ‘evil twin’ of climate change – and for good reason.
Roughly a quarter of the carbon dioxide in the atmosphere ends up in the oceans where it forms carbonic acid. When carbon dioxide dissolves it alters the water chemistry – lowering the pH and increasing acid levels.
