A new study identifies a major correlation flaw in paleoclimate research. The \u201cmissing\u201d correlations are more common than correlations.<\/mark><\/em><\/strong><\/p>\n\n\n\n

In the past we have identified major contradictions in the widely-accepted contention that the entire Earth freezes its way into glacial climates that cyclically last roughly 100,000 years, interrupted by ~10,000-year interglacials.<\/p>\n\n\n\n

This 100,000-year glacial-interglacial cycle supposedly lasted only 41,000 years until the last 900,000 years or so.<\/p>\n\n\n\n

But many recent studies show the climate was warmer than today during what has been referred to as the last glacial period, when CO2 was allegedly under 200 ppm. For example:<\/p>\n\n\n\n

New Study: The Lowest Tibetan Plateau Glacial Temps Were Still 3\u00b0C Warmer Than Today<\/a><\/h4>\n\n\n\n

California\u2019s Mean Annual Temps Were Up To 3.8\u00b0C Warmer Than Today During The Last Glacial<\/a><\/h4>\n\n\n\n

New Study Finds Australian Sea Temperatures Multiple Degrees Warmer Than Today During The Last Glacial<\/a><\/h4>\n\n\n\n

Another Study Says Europe Was At Times Warmer During The Last Glacial When CO2 Levels Were 40% Lower<\/a><\/h4>\n\n\n\n

10 Recent Studies Affirm It Was Regionally 2-6\u00b0C Warmer Than Today During The Last Glacial<\/a><\/h4>\n\n\n\n

<\/p>\n\n\n\n

And now another analysis (Jonas, 2022<\/a><\/strong>) points out the lack of correlation between Milankovitch cycles and climate and the chaotic, widely varying, non-cyclical nature of glacial and interglacial climate durations and amplitudes. The non-correlations, or \u201cmissed cycles,\u201d occur just as or more often than the ones that \u201chit.\u201d<\/p>\n\n\n\n

The conclusion is that \u201cthere never was a 41,000-year cycle,\u201d and \u201cthere is no 100,000-year cycle\u201d either.<\/p>\n\n\n\n

Instead, Earth has operated and continues to operate as a \u201ccoupled, non-linear, chaotic system.\u201d<\/p>\n\n\n
