David Nield,    -  Science alertStephan: What is clear to environmental scientists is that climate change is at what they call a "tipping point." Unfortunately, the American government is doing nothing to prepare the country, and protect the wellbeing of the people and the environment. I am going to start focusing on what Americans, as individuals, can do to protect their wellbeing as the climate transition occurs. Citation: Multidecadal Atlantic “Warming Hole” Heat Content Variations Are Caused by Ocean Heat Transport, Not by Surface Fluxes https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2025GL118383 There’s a strange anomaly in the North Atlantic, just south of Greenland: A ‘cold blob’ of ocean and air that’s cooling down while the rest of the world warms up. Now a new analysis of this cold blob points to a serious and imminent climate problem. An international team of researchers used satellite data, reanalysis records, and ocean heat content data, including records extending back to 1955, to try to figure out the driving forces behind the blob. Up to this point, there have been two schools of thought: either ocean currents are bringing less heat into the region, or the ocean in that area is losing more heat through the surface. Their results support the first explanation, and they conclude that we’re now very close to a dangerous tipping point. The Atlantic’s cold blob is a sign of weakening of the Atlantic Meridional Overturning Circulation (AMOC), the researchers conclude. This is showing signs of shutting down entirely – an event predicted to have consequences for the planet far more severe than a cold patch in the ocean. “Given the well-established existence of a tipping point of the AMOC, as well as [...]Read the Full Article »
