Scientists Say New Government Climate Report Twists Their Work wired.com Jul 30, 2025 9 facts
claimJeff Clements, a marine ecologist at Canada’s Department of Fisheries and Oceans, stated that the Department of Energy (DOE) report accurately cites his research on ocean acidification and fish behavior from an explicit textual perspective.
claimJosh Krissansen-Totton states that calcium carbonate saturation is quickly diminishing in the ocean alongside rising acidity, and that dissolved calcium carbonate is essential for many marine species that rely on it to build their shells.
quote“I want to make it clear that our results should not be interpreted to mean ocean acidification (or climate change more generally) is not a problem,”
claimJeff Clements stated that his literature review finding fish behavior relatively unaffected by ocean acidification does not imply that other ocean ecosystems, biological processes, and species are similarly unaffected.
claimJosh Krissansen-Totton, an assistant professor at the University of Washington, stated that his research on ocean acidity billions of years ago has "no relevance" to the impacts of human-driven ocean acidification today.
claimOceans have been absorbing CO2 from the atmosphere since the beginning of the industrial revolution, causing the water to become considerably more acidic over the past two centuries.
claimJeff Clements's research focuses on correcting earlier studies that connected the effects of ocean acidification to fish behavior.
quote“Much of the public discussion of the effects of ocean ‘acidification’ on marine biota has been one-sided and exaggerated,”
claimThe Department of Energy (DOE) report uses Jeff Clements's research to support a section that downplays the impact of ocean acidification.
Misleading U.S. Department of Energy climate report chooses bias ... science.feedback.org Aug 5, 2025 8 facts
claimA 2022 meta-analysis by Clements et al. published in PLOS Biology reveals an extreme 'decline effect' in the impacts of ocean acidification on fish behavior.
claimThe U.S. Department of Energy report implies that ocean acidification is not a threat to marine life and that the Great Barrier Reef is in good health, a claim the source characterizes as misleading.
claimOcean acidification weakens the calcium-based skeletons that corals build for protection.
perspectiveFredrik Jutfelt, a professor at the University of Gothenburg, asserts that the U.S. Department of Energy report is unscientific and biased because it selectively cites studies showing minor effects of ocean acidification and heat waves while ignoring literature documenting stronger negative impacts.
claimOcean acidification occurs when Earth's oceans absorb atmospheric carbon dioxide, which reacts with the water to form carbonic acid.
claimThe U.S. Department of Energy report claims that marine life can adapt to ocean acidification, a position that contradicts scientific evidence regarding the rapid rate of current acidification.
referenceHoegh-Guldberg et al. published a study titled 'Coral Reef Ecosystems under Climate Change and Ocean Acidification' in Frontiers in Marine Science in 2017.
claimThe U.S. Department of Energy report fails to reference the vast body of scientific literature demonstrating the negative impacts of rising CO2 levels on ocean organisms, specifically regarding calcification rates, growth, fecundity, and survival.
Sustainable Energy Transition for Renewable and Low Carbon Grid ... frontiersin.org Mar 23, 2022 5 facts
measurementA 0.1 drop in pH causes approximately a 30% increase in ocean acidity.
claimGreenhouse gas emissions contribute to sea-level rise and ocean acidification, the latter of which is caused by the absorption of carbon dioxide by the oceans.
claimOcean acidification interferes with the ability of marine life to extract calcium from water to build shells and skeletons.
claimCarbon dioxide emissions cause ocean acidification, which negatively impacts aquatic life.
claimOcean acidification interferes with marine life's ability to extract calcium from water to build shells and skeletons, posing a danger to aquatic ecological balance.
Comprehensive Overview on the Present State and Evolution of ... link.springer.com Aug 9, 2024 4 facts
claimOcean acidification adversely affects the fitness of various marine species, including coccolithophores, crabs, sea urchins, and the early life stages of fish.
claimOcean acidification hinders the ability of marine organisms such as corals, oysters, and pteropods to create calcium carbonate shells and skeletons.
claimResearch indicates that ocean acidification, both independently and in combination with stressors like eutrophication, warming, and hypoxia, impacts marine species, ecosystems, and biogeochemical cycles.
claimOcean acidification is the reduction in ocean pH caused by heightened CO2 levels in the water.
The Energy Department "Red Team" Critique of Greenhouse-Gas ... revkin.substack.com Jul 31, 2025 2 facts
claimHoward Browman (2016) noted that scientific studies reporting no significant effects of ocean acidification are less likely to be published, a phenomenon known as publication bias.
claimThe Energy Department 'Red Team' report dismisses 'ocean acidification' as a misnomer in Section 2.2.1, noting that oceans remain alkaline.

claimIncreased atmospheric carbon dioxide levels increase ocean acidity, which decreases the ability of marine organisms to form shells and calcium carbonate structures like coral skeletons.
