El Nino, definition of

A warming of the surface waters of the eastem equatorial Pacific that occurs at irregular intervals of 2-7 years, usually lasting 1-2 years. Along the west coast of South America, southerly winds promote the upwelling of cold, nutrient-rich water that sustains large fish populations, that sustain abundant sea birds, whose droppings support the fertilizer industry Near the end of each calendar year; a warm current of nutrient-poor tropical water replaces the cold, nutrient-rich surface water Because this condition often occurs around Christmas, it was named El Niho (Spanish for boy child, referring to the Christ child). In most years the warming lasts only a few weeks or a month, after which the weather patterns return to normal and fishing improves. However; when El Nino conditions last for many months, more extensive ocean warming occurs and economic results can be disastrous. El Nino has been linked to wetter; colder winters in the United States; drier; hotter summers in South America and Europe; and drought in Africa.

• Climate Oscillations 11: Oceanic Niño Index (ONI)
  ENSO affects weather all over the world but doesn't track the global mean surface temperature (GMST), at least for the last 35 years. Is GMST an appropriate measure of climate change?
• The Warming Of 2023 Was Due To Natural Causes, Not Man-Made
  The volcano in question occurred at the end of January 2022. Not much happened until around May 2023. Then, however, the “impulse response” of the climate system probably took place: in September 2023, an additional warming of 0.58 °C was detected...
• A Tale of 2 Opposing Ocean Warming Narratives!
  One suggests recent ocean warming has been totally driven by human emissions that amplified the greenhouse effect. That narrative is supported the correlation with rising CO2 that blankets the globe. The second suggests the El Niño-Southern Oscillation...
