The polar caps can be compared with a fridge – energy is constantly extracted from them due to radiation to space and replenished with heat from lower latitudes. Only a slight imbalance between the fluxes is already sufficient to cause…

GOES-17 visible-band snapshot of the Hunga Tonga–Hunga Ha'apai eruption on 15 Jan 2022 (04:30 UTC). The key point: the plume rose unusually high into the stratosphere, helping loft water vapour that can influence climate for years.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 A broad view of…
