Maybe history is trying to tell us future climate conditions are more unpredictable than advocates of IPCC doctrines would have us believe.<\/em><br>\u2013 \u2013 \u2013<br>An El Ni\u00f1o event has officially begun,\u00a0<em><a href=\"https:\/\/www.sciencedaily.com\/releases\/2023\/07\/230703133053.htm\">says Science Daily<\/a>.<\/em>The climate phenomenon, which originates in the tropical Pacific and occurs in intervals of a few years will shape weather across the planet for the next year or more and give rise to various climatic extremes. El Ni\u00f1o-like conditions can also occur on longer time scales of decades or centuries. This has been shown to have occurred in the recent past by an international research team led by Ana Prohaska of the University of Copenhagen and Dirk Sachse of the German Research Centre for Geosciences (GFZ).Their analysis of biomarkers \u2014 organic molecules or molecular fossils from vascular plants \u2014 in the sediments of a lake in the Philippines indicates an unusually dry phase in the region during the Little Ice Age between 1600 and 1900 A.D.The results have now been published in the journal Communications Earth and Environment. They show how important the understanding of past dynamics of the tropical Pacific ocean-atmosphere climate is for the improvement of climate models and the prediction of future climate changes.<br>. . .<br><strong>El Ni\u00f1o-like phenomena on longer time scales<\/strong>While El Ni\u00f1o is an interannual climate phenomenon, the climate system of the tropical Pacific can also exhibit El Ni\u00f1o-like behaviour on longer time scales of decades and centuries, which is linked to the east-west gradient of sea surface temperatures in the Pacific.Such behaviour has been shown to have transpired in the recent past by a team led by Ana Prohaska, assistant professor at the University of Copenhagen and formerly a visiting scientist at the GFZ, and Dirk Sachse, working group leader in GFZ Section 4.6 \u201eGeomorphology\u201c and director of Topic 5 \u201eLandscapes of the Future\u201c of the Helmholtz research programme \u201eChanging Earth \u2014 Sustaining our Future,\u201c in the journal Communications Earth and Environment.They describe such a pronounced shift to El Ni\u00f1o-like conditions in the second half of the Little Ice Age, lasting from about 1630 to 1900 A.D.What is particularly remarkable is the short period of only one generation within which conditions changed for a period of more than 200 years.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><em>Full article\u00a0<a href=\"https:\/\/www.sciencedaily.com\/releases\/2023\/07\/230703133053.htm\">here<\/a>.<\/em><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Evidence that what is today called \u201aclimate change\u2018 can naturally occur, and has occurred, over a relatively short timescale \u2013 described here as \u201aremarkable\u2018.
