The La Ni\u00f1as are more frequent than the El Ni\u00f1os. Interestingly, the opposite was true during the rapid warming we had from 1975 \u2013 1999, when El Ni\u00f1os were more common. But then it reverts back again around 1998\/99. Is there a pattern here?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It is established in climate science that the climate underwent a profound shift in 1976\/77, related to the ocean currents.[2] In IPCC AR4, they write: \u201c<em>The 1976\u20131977 climate shift in the Pacific, associated with a phase change in the PDO from negative to positive, was associated with significant changes in ENSO evolution<\/em>.\u201d The Pacific Decadal Oscillation (PDO) shifted from a \u2018cold\u2019 to a \u2018warm\u2019 phase during these two years.[3] The ENSO also became dominated by the El Ni\u00f1o phase, which is characterized by warmer temperatures.[4] These changes affected the global climate, and a rapid warming began.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But what happened in the years just before 2000? As seen in Figure 1, ENSO reverts to being dominated by the \u2018colder\u2019 La Ni\u00f1a at that time.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/notrickszone.com\/wp-content\/uploads\/2023\/04\/Gabriel_1.png\"><\/a><\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"723\" height=\"508\" data-attachment-id=\"253991\" data-permalink=\"https:\/\/climatescience.press\/?attachment_id=253991\" data-orig-file=\"https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2023\/04\/0Gabriel_1.png?fit=954%2C670&amp;ssl=1\" data-orig-size=\"954,670\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"0Gabriel_1\" data-image-description=\"\" data-image-caption=\"\" data-large-file=\"https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2023\/04\/0Gabriel_1.png?fit=723%2C508&amp;ssl=1\" src=\"https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2023\/04\/0Gabriel_1.png?resize=723%2C508&#038;ssl=1\" alt=\"\" class=\"wp-image-253991\" srcset=\"https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2023\/04\/0Gabriel_1.png?w=954&amp;ssl=1 954w, https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2023\/04\/0Gabriel_1.png?resize=300%2C211&amp;ssl=1 300w, https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2023\/04\/0Gabriel_1.png?resize=768%2C539&amp;ssl=1 768w\" sizes=\"auto, (max-width: 723px) 100vw, 723px\" \/><\/figure>\n<\/div>\n\n\n<p class=\"has-text-align-center wp-block-paragraph\"><a href=\"https:\/\/notrickszone.com\/wp-content\/uploads\/2023\/04\/Gabriel_1.png\"><\/a><em>Figure 2.

ENSO often leads the PDO, especially in the La Ni\u00f1a phase.<\/em><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That ENSO and PDO are climatically connected is well known. Usually, it\u2019s the ENSO that leads the shifts in the PDO cycle, see Figure 3d in [4].<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The standard explanation for the 1976\/77 climate shift is that the period before that was cold due to a lot of aerosols in the atmosphere that reduced the amount of warming solar radiation.[8] But around those years, the warming forcing from CO2 took over the cooling aerosols, the narrative goes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Cannot be explained by CO2<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">CO2 has been increasing monotonically throughout the modern era, and aerosols increased monotonically up until about 1980.[9] Thus, it is unreasonable that more than&nbsp;<em>one<\/em>&nbsp;of the climate shifts in the modern era can be explained by the relationship of CO2 to aerosols.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It is more likely that climate shifts are due to confluences between different natural variations that we can observe in various climate indices. We can see, for example, that also the long-term variations in the&nbsp;<a href=\"https:\/\/en.wikipedia.org\/wiki\/Atlantic_multidecadal_oscillation\">AMO<\/a>&nbsp;and&nbsp;<a href=\"https:\/\/www.ncei.noaa.gov\/access\/monitoring\/enso\/soi\">SOI<\/a>&nbsp;show similar turning points to the cumulative ENSO and the PDO, as in figure 4.[3]<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Are we currently in a shift towards a colder climate?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">One indication of that, is that we\u2019re still quite far away from the previously observed threshold levels in the cumulative ENSO index.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>A note on ENSO indexes<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The&nbsp;ENSO variation between La Ni\u00f1a\/Neutral\/El Ni\u00f1o is defined by different indices. The traditional one is called NINO 3.4, which picks up temperature differences in two regions in the Pacific ocean. If the average value is below -0.5 degrees three months in a row, it is classified as La Ni\u00f1a, above 0.5 it is El Ni\u00f1o, where the numbers refer to the temperature deviation in two areas of the Pacific Ocean.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The MEI.v2, which is used in this article, is an alternative index, which weighs together five different variables: sea surface air pressure, sea surface temperature, zonal and meridional components of the surface wind, and outgoing longwave radiation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The MEI uses the same numerical scale as for Nino 3.4, but the amplitude differs. MEI.v2 exists from 1979 and the earlier MEI index exists from 1950, and in a reconstruction back to 1871. This is what the raw data looks like for the MEI.v2 index:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a
