The effect of #ClimateChange on sources of #radionuclides to the #MarineEnvironment
Published: 16 March 2024
Justin P. Gwynn, Vanessa Hatje, Núria Casacuberta, Manmohan Sarin & Iolanda OsvathAbstract:
"Climate change interacts with the sources and cycling of contaminants, such as radionuclides, in the environment. In this review, we discuss the implications of climate change impacts on existing and potential future sources of radionuclides associated with human activities to the marine environment. The overall effect on operational releases of radionuclides from the nuclear and non-nuclear sectors will likely be increased interference or prevention of normal operations due to weather-related events. For certain #RadioactiveWaste dumped at sea and sunken #NuclearSubmarines, the impact of climate change and ocean #acidification on the release of radionuclides and their subsequent fate in the marine environment should be considered further. Fluxes from secondary sources of radionuclides in the marine and terrestrial environment and cryosphere will change in response to climate change impacts such as sea level rise, warming and changes in precipitation patterns. In addition, climate change impacts may increase the risk of releases of radionuclides from operational and legacy wastes on land to the marine environment. Overall, our synthesis highlights that there is a need to understand and assess climate change impacts on sources of radionuclides to the marine environment to meet environmental and management challenges under future climate scenarios."Full paper:

Brewing oceans, brewing storms, making a blooming disaster
"Over the past year, Australia’s oceans have been hotter than ever before...The continued burning of fossil fuels has caused our atmosphere to warm by approximately 1.2 degrees C since the pre-industrial era....If you change what happens in the oceans, you start to change the whole system...The problem with climate change is we’re hitting that system incredibly hard with extra energy and we’re putting a lot of pressure on the oceans."

👏 Congrats to Danai Filippou, IMPRS-ESM PhD candidate in the group of @TatianaIlyina, for winning the best poster award at the 23rd Swiss Climate Summer School in Ascona! 🏆
Her work, “Ocean Compound Extreme Events Under Emission Reduction and Negative CO₂ Pathways”, explores how compound extremes, like marine heatwaves combined with #acidification or low oxygen extremes, evolve under emission cuts and net-negative CO₂.
Have you been to a #SummerSchool this year?

Ocean acidification by Fabrice Pernet, 2025
Understanding the effects, exploring the solutions
Carbon dioxide CO2 emissions, resulting from the combustion of fossil fuels by human activity, reinforce the greenhouse effect and cause climate disruption. While public awareness of this global problem is growing, ocean acidification, described as “the other CO2 problem”, is still considerably unknown.

What #ClimateChange Means for the #Mediterranean Sea
#Climate change threatens marine and coastal #ecosystems in the Mediterranean region. Warming, sea level rise, and ocean #acidification are occuring there more intensely and rapidly than the global average. https://idw-online.de/en/news857739 -
So, something else that is a key element of ensuring #HumanWelfare remains in the SW range is to make sure folks are fed -- without destroying the environment! That's where #RegenerativeAgriculture , #SustainableAgriculture, #FoodForests, #CommunityGardens, etc., come into play. But #Rewilding and restoring key natural systems are also very important!
7. #Wildlife faces #extinction cascades as #ecosystems collapse.
"Vertebrate populations have declined by an average of 69 percent since 1970, with some regions experiencing losses exceeding 90 percent as habitat destruction, climate change, #pollution, and direct #exploitation combine to trigger ecosystem-wide collapse that eliminates the #biodiversity necessary to maintain stable #FoodWebs. Species extinction rates now exceed background levels by 100 to 1,000 times, representing a mass extinction event comparable to the asteroid impact that eliminated the dinosaurs but compressed into a timeframe measured in decades rather than millennia.
"The collapse of insect populations threatens #pollination services essential for agricultural production, while marine ecosystems face #acidification, warming, and #overfishing that eliminate entire trophic levels and destabilize ocean food chains supporting billions of people. Domestic animals face parallel threats as #IndustrialAgriculture concentrates genetic diversity into vulnerable #monocultures while climate change disrupts feed production and increases disease pressure on livestock populations already stressed by intensive production methods designed to maximize short-term yields rather than long-term #resilience."

Another planetary boundary crossed.
Ocean #acidification has been identified as a planetary process approaching a boundary that could lead to unacceptable environmental change.
By 2020, the average global #ocean conditions had already crossed into the uncertainty range of the ocean acidification boundary.
Up to 60% of the global subsurface ocean (down to 200 m) had crossed that boundary, compared to over 40% of the global surface ocean.
These changes result in significant declines in suitable #habitats for important calcifying #species.

Groundwater in the Arctic is delivering more carbon into the ocean than was previously known
A relatively small amount of #groundwater trickling through #Alaska's #tundra is releasing huge quantities of #carbon into the #ocean, where it can contribute to #ClimateChange, according to new research out of The University of Texas at Austin.
As the tundra continues to thaw and the flow of submarine groundwater ratchets up, Demir said that the outflow of carbon from shore to sea could effectively make ocean surface waters a carbon source to the #atmosphere. The #CO2 released via groundwater could also contribute to ocean #acidification.
"The #Arctic coast is changing in front of our eyes," said Bayani Cardenas, a co-author of this study and professor at the Jackson School's Department of Earth and Planetary Sciences. "As #permafrost thaws, it turns into coastal and submarine #aquifers. Even without this thawing, our studies are among the first to directly show the existence of such aquifers."https://phys.org/news/2025-01-groundwater-arctic-carbon-ocean-previously.html

Melting #permafrost is bad, mmkay.
Iron and sulfite minerals are now leaching into once pristine arctic rivers, acidifying them. One the sulfur acidifies the water it begins to leach toxic compounds and elements into the rivers. It was more commonly seen in rivers where abandoned mines were nearby.

Under anthropogenic stress, we talk a lot about #ocean #warming and ocean #acidification... but we should also be talking more about ocean #deoxygenation, as it is an ongoing problem. To understand just how bad it can get ( #extinction event bad ), we must turn, as usual, to the geological record.

#Polluting #Shipwrecks Are the Ticking #TimeBomb at the Bottom of Our #Oceans
As their structures break down, the wrecks could release toxic substances into the #environment.
December 11, 2024
"At the bottom of the oceans and seas lie more than 8,500 shipwrecks from two world wars. These wrecks have been estimated to contain as much as 6 billion gallons of oil, as well as munitions, toxic heavy metals and even chemical weapons [and NUCLEAR weapons and materials!].
"For decades, these wrecks have largely lain out of sight and out of mind. But all this time, their structures have been degrading, inexorably increasing the chances of sudden releases of toxic substances into the marine environment.
"In parts of the globe, climate change is exacerbating this risk. Rising ocean temperatures, #acidification and increasing #storminess accelerate the breakdown of these wrecks.
"Of course, wrecks from the world wars are far from the only ones to be found at the bottom of the sea, with many others adding to the problem. The cost of addressing this global issue has been estimated at US$340 billion (£261 billion).
"How many of these wrecks pose a threat to people’s safety, to coastal communities and to the environment? What can be done – and why haven’t we done it sooner?"
-
Shifting #wind patterns have a lot of knock-on effects. In shallow seas (like ancient epicontinental #sea), those can be rather dramatic. Take the Persian/Arabian Gulf; a great modern case study. There, weakening winds have contributed to rapid #warming, deoxygenation, and #acidification.
