Abstract:
"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."

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."

Ocean hypoxia: The science of climate change in the sea

"... The field will need to draw on ... advances to meet demands for adaptation solutions to the continued progression of global ocean deoxygenation, particularly in conjunction with ocean acidification and marine heatwaves in a multi-stressor scenario."

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!

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."
