  > Since total ocean heat capacity is about 1000x greater than total atmosphere, it means that a barely measurable temperature increase in the ocean (1/1000th of a degree C) could drive a massive spike in global air temperature (1 degree C). https://scholarsandrogues.com/2013/05/09/csfe-heat-capacity-air-ocean/ https://scholarsandrogues.com/2013/05/09/csfe-heat-capacity-... As seen/felt now in Chile, perhaps: > Mid-winter temperatures above 35 degrees Celsius in South America leave climatologists in disbelief > Data from Chile's national meteorological agency, Dirección Meteorológica de Chile, shows several weather stations in the country reached temperatures above 35C on August 1. > This is between 10C and 20C above what is normal for this time of year in parts of Chile and Argentina, according to data from the European Centre for Medium Range Weather Forecasts (ECMWF). > What's causing South America's heat? Dr Perkins-Kirkpatrick said the South American heat extremes were also likely to bear the fingerprints of climate change. > "There are likely multiple causes to these temperatures — record warm sea surface temperatures in the Atlantic, the developing El Niño in the Pacific, a heat dome that was recently over the region combined with foehn winds, and anthropogenic climate change," she said. https://www.abc.net.au/news/2023-08-04/south-america-extreme-heat-mid-winter-climate-change-scientists/102678662 https://www.abc.net.au/news/2023-08-04/south-america-extreme...
