– How Soon Might the Atlantic Ocean Break? Two Sibling Scientists Found an Answer—and Shook the World
Sandra Upson in Wired, July 25, 2024. “A gigantic, weather-defining current system could be headed to collapse. Peter and Susanne Ditlevsen had a simple yet controversial question: How much time might we have left to save it?…The AMOC transports a staggering amount of energy. Like a million nuclear power plants. It is such a core element of the Earth system that its collapse would radically alter regional weather patterns, the water cycle, the ability of every country to provide food for its inhabitants… The two scientists made a plot of the numbers and a neat cluster emerged. Yes—2057. But that’s just the middle point: In 95 percent of the model’s simulations, the AMOC tipped sometime between 2025 and 2095… In footnote 4 of the IPCC’s latest big report, “very unlikely” meant that, in the panelists’ view, the AMOC had less than a 1-in-10 chance of collapsing before 2100. One in 10. Those odds didn’t strike him as “very unlikely.” Russian roulette is one in six, and we all agree that’s a bad idea. Plus, the IPCC had given its prognosis only a “medium confidence” rating. To Ditlevsen, that sounded a lot like “we have no clue.”
– Is There Robust Evidence for Freshwater-Driven AMOC Changes? A Synthesis of Data, Models, and Mechanisms
Sophia K.V. Hines et al. 2025 in Oceanography “The Atlantic Meridional Overturning Circulation (AMOC) transports heat to high latitudes and carbon to the deep ocean. Paleoceanographic observations have led to the widely held view that the strength of the AMOC was significantly reduced at two intervals during the most recent glacial-to-interglacial transition, with global climate impacts. Climate models predict that the AMOC may decline in the future due to anthropogenic forcing, but the time periods for modern observations are too short to detect recent trends with high confidence. To understand the likelihood of future changes in the AMOC, it is important to understand the mechanisms that drove past changes in AMOC strength. In this paper we review (1) the paleoceanographic proxy data that have led to the widespread view that the AMOC sharply decreased for periods of several thousand years during the last deglaciation, (2) climate model simulations of the last deglaciation, with particular attention to their use of fresh water to alter the AMOC, (3) the physical mechanisms that could have driven past changes in the AMOC, and (4) how insights from past ocean change can inform our understanding of what may happen in the future.”

It offers a perspective of the early days of public awareness of climate change. I was horrified at the time that DVL, editor of RD, titled the article as such, but 40 years later, it does not seem so outlandish – david p “During the balmy days of last fall and early winter, we may have wondered whether winter as we have traditionally known it was ever to arrive. That winter may have been a “normal anomaly.” Alternatively, it could represent the begining of a distinct warming trend that many scientists expect will begin in the eighties, and that will stay with us at least until our fossil fuels are exhausted…”
Land & Sea: The uncertain future of Maritime forests (VIdeo, 22 min)
CBC News Nova Scotia, Nov 16, 2025: “In the Maritimes, the majority of forested land is in private hands, often as small woodlots are passed down through generations. Those forests have sustained families and communities for centuries but many aging woodlot owners face an uncertain future. Now, some are offering a new way to safeguard those forests by harnessing their ability to store carbon.Chapters: 00:00 Welcome to Land & Sea; 01:04 Future of woodlot owners; 04:15 What are carbon offsets?; 05:56 Measuring carbon in forests; 09:04 Not enough to offset emissions; 10:07 Pulling carbon out of the atmosphere; 11:10 Pitching carbon offsets to landowners; 13:40 Stewardship of land; 16:21 Tackling a changing forest; 18:35 Coping with climate change” COMMENT, Very informative interviews in the field with Dale Prest, Anthiny Taylor and others.
