The Sperm Whale piece is heart breaking Luke, the AMOC potential slow down terrifying. There are still large knowledge gaps in healthcare professionals which although understandable needs correcting. I want all those in healthcare to understand planetary boundaries, Keeling Curves and tipping points like the AMOC. We can then recruit them to use their trusted voices to communicate further and inspire actions which may help us survive.
Another great in-depth explanation about what’s happening to the AMOC and the serious climate impacts that will result. Whilst the impacts of the slowing AMOC are expected to occur over a very long time period, the question arises as to the probability that process may speed up significantly?
🖇️ Trusting projections of the Atlantic Meridional Ocean Circulation (AMOC) weakening is difficult because of significant discrepancies between observational data and climate model outputs regarding its historical trend:
While the IPCC reports have indicated a weakening, the confidence in these findings have varied, and recent climate models (CMIP6) have shown a slight strengthening over historical periods, contrary to some proxy data suggesting a decline…
Studies investigating such weakening are based on so-called 'hosing' model experiments 'adding' freshwater to the entire North Atlantic to simulate ice melt, to document its effect on the AMOC, although this recent study highlights the limitations of these experiments and ways to make them more realistic…
This observation-model discrepancy, along with the large natural variability of the AMOC and challenges in calibration, makes future AMOC projections uncertain and highlights the need for more direct observations and improved models, such as those from current monitoring programs.
