Long term, there’s no doubt what’s in control of the world’s temperature trend. The vast belching of greenhouse gasses by fossil fuel industry and related non-renewable based machinery has caused atmospheric carbon levels to hit 405 ppm CO2 and 490 ppm CO2e this year. All this added carbon has caused the world to warm by a record 1.22 C since 1880s levels during 2016 (approx). But superimposed over this long term warming trend is the natural variability based ebb and flow of atmospheric and surface ocean heat that is the ENSO cycle.
ENSO — A Wave Pattern Overlying the Long Term Warming Trend
Think of it as a smaller wave pattern that overlaps the current global upswing in temperatures. As El Nino builds and comes into the fore, natural forcings caused by periodic ocean surface warming in the Equatorial Pacific push global temperatures higher. This tends to add to the…
