Acidification of Oceans

By Tyler Rohr, University of Tasmania; Anthony Richardson, The University of Queensland; and Elizabeth Shadwick, CSIRO | – The ocean holds 60 times more carbon than the atmosphere and absorbs almost 30% of carbon dioxide (CO₂) emissions from human activities. This means the ocean is key to understanding the global carbon cycle and thus our […]

Fossil-Fuel Burning Humans are as Catastrophic for Sea Life as the Chicxulub Meteor was that also killed the Dinosaurs

Ann Arbor (Informed Comment) – A new study by Justin L. Penn and Curtis Deutsch shows that over the next 200 years, humanity could kill off half of all marine life by by pumping billions of tons of carbon dioxide into the atmosphere. CO2 is a greenhouse gas that traps the sun’s heat on earth […]

IPCC – Carbon Dioxide concentrations highest in 2 mn years, Provoking ever more Extreme Weather

The product of vast international cooperation, the report reflects the scientific community’s certitude that the globe’s climate is rapidly changing as a direct result of humanity burning coal, gasoline and natural gas, putting tens of billions of tons […]

Coral reef scientists raise alarm as climate change decimates ocean ecosystems vital to fish and humans

By Sam Purkis | ( The Conversation) – The Chagos Archipelago is one of the most remote, seemingly idyllic places on Earth. Coconut-covered sandy beaches with incredible bird life rim tropical islands in the Indian Ocean, hundreds of miles from any continent. Just below the waves, coral reefs stretch for miles along an underwater mountain […]

More CO2 in our Atmosphere now than any time since 3.6 mn Years Ago, when Oceans were 90 feet higher (that’s our fate)

Ann Arbor (Informed Comment) – In a scientific shocker, the National Oceanic and Atmospheric Administration has found that despite the slowdown in carbon dioxide emissions in 2020 because of the pandemic, the concentration of CO2 in the atmosphere rose to a global average of 412.5 parts per million (ppm) from 410 in 2019. At the […]

Saving the Planet: Why a net-zero future depends on the ocean’s ability to absorb carbon

By Anya M. Waite, Brad deYoung, Chris Milley, and Ian G. Stewart | – Most of us growing up along Canada’s East Coast never worried about hurricane season. Except for those working at sea, we viewed hurricanes as extreme events in remote tropical regions, seen only through blurred footage of flailing palm trees on the […]

It might be the world’s biggest ocean, but the mighty Pacific is in peril
