Acid Oceans? & Oyster Shells

What’s Natural? Guest post by Jim Steele Published July 14, 2020 in the Pacifica Tribune (I wrote a white paper for the CO2  Coalition, providing more details and references to peer reviewed science regards how marine life counteracts ocean acidification. That paper can be downloaded here ) Search the internet for “acid oceans” and you’ll…

Arctic Ocean acidification worse than previously expected

University of Bern The Arctic Ocean will take up more CO2 over the 21st century than predicted by most climate models. This additional CO2 causes a distinctly stronger ocean acidification. These results were published in a study by climate scientists from the University of Bern and École normale supérieure in Paris. Ocean acidification threatens the…

Podcast: Why the Oceans Really Aren’t “Acidifying” but the Term Is Being Abused by Science and Media

Science and media outlets claim ocean acidification is happening due to increased carbon dioxide in the atmosphere. But objective data show the ocean is far from acidic according to Dr. Caleb Rossiter, executive director of the CO2 Coalition and a statistician who has studied climate change closely. Host Anthony Watts and Rossiter talk about how…

Measuring climate change

New study marks first attempt to identify similarities and differences of ocean acidification on both US coast, while noting vulnerable hot spots University of DelawareShare Print E-Mail One of the earth’s biggest allies in the fight against global warming is the world’s oceans. Since the industrial revolution, the burning of fossil fuels has caused carbon dioxide, the…

Dissolving Dungeness?

By Jim Steele, Published in Pacifica Tribune March 8, 2020 What’s Natural Like New England’s lobsters, savory Dungeness crabs are San Francisco and the northwest’s iconic seafood. While fisheries around the world have declined from overexploitation, Dungeness crabs have been sustainable despite intensive harvesting over the past 40 years. Their resilience partly relies on mature…

Dungeness Crabs Redux

Guest Post by Willis Eschenbach Well, after my last post, The Solution To Dissolution, I thought I was done with the Dungeness crab question. And I was happy to be done with those chilly crustaceans. Writing that post brought back memories of how cold the fishery is. I remember leaving out from Eureka harbor at…

The Solution To Dissolution

Guest Post by Willis Eschenbach The British tabloid “The Guardian” has a new scare story about what is wrongly called “ocean acidification”. It opens as follows: Sounds like the end of times, right? So let me start with a simple fact. The ocean is NOT acidic. Nor will it ever become acidic, except in a…

Ocean acidification a big problem — but not for coral reef fish behavior

A comprehensive multi-year project challenges previous findings Norwegian University of Science and Technology A three-year, comprehensive study of the effects of ocean acidification challenges previous reports that a more acidic ocean will negatively affect coral reef fish behaviour. The study, conducted by an international coalition led by scientists from Australia and Norway, showed that coral…

Marine biology: Acidified oceans may corrode shark scales

Prolonged exposure to high carbon dioxide (acidified) seawater may corrode tooth-like scales (denticles) covering the skin of puffadder shysharks, a study in Scientific Reports suggests. As ocean CO2 concentrations increase due to human activity, oceans are becoming more acidic, with potential implications for marine wildlife. Although the effects of acidified water have been studied in…

Tiny shells reveal waters off California are acidifying twice as fast as the global ocean

NOAA Headquarters In first-of-its-kind research, NOAA scientists and academic partners used 100 years of microscopic shells to show that the coastal waters off California are acidifying twice as fast as the global ocean average — with the seafood supply in the crosshairs. California coastal waters contain some of our nation’s more economically valuable fisheries, including…
