Ocean Rises, Science Sinks

Ever wondered how a tiny rise in sea level—let’s say, the aquatic equivalent of topping up your birdbath—might be responsible for frigid winters rampaging through East Asia? No? Well, Nature Communications thinks you should, in an article yclept “Intensification of extreme cold events in East Asia in response to global mean sea-level rise“.
Here’s their premise, as bold as a flashing warning sign on your grandma’s thermostat: A global mean sea-level rise of 15–30 cm can intensify extreme cold events in East Asia, thanks to a retooled atmospheric circulatory engine, weakening westerlies, and powered-up blocking episodes.
Mind you, this is not about that old chestnut, Arctic amplification or vanishing sea ice; it’s the earth-modeling equivalent of arguing that rearranging the living room somehow makes next winter’s snow deeper.
So, how did we get here?
I did what any skeptical denizen of the scientific peanut gallery would do: pondered their use of the NorESM1-F Earth System Model, the chosen oracle of this saga. Picture it—a whopping 2200-year sensitivity experiment, climate dials set to “controlled conditions” (CO₂ steady at 400 ppm, as if the atmosphere were on cruise control). The researchers periodically poured another cupful into the global ocean, then waited to see if the weather started shivering in East Asia.
