It\u2019s just another day in the hottest ever hyperbole race. The most unprecedentedly unprecedented record where more scientists on Earth than ever before, forget more of the  Pleistocene than they ever have in history.<\/strong><\/p>\n\n\n\n

We know it was hotter in the Holocene, hotter in the\u00a0Eemian<\/a>, and hotter for most of the\u00a0last 200 million years<\/a>, but we have 130 years of thermometer records so it\u2019s time to get hysterical. Just because the\u00a0seas were 1 \u2013 2 meters higher,<\/a>\u00a0or\u00a0nine meters higher,<\/a>\u00a0it\u2019s nothing\u2026<\/p>\n\n\n\n

Here\u2019s how 2023 became the hottest year on record<\/a><\/h3>\n\n\n\n

This year didn\u2019t just shatter records. It changed the scales.<\/p>\n\n\n\n

Graph after graph tracking this year\u2019s soaring global temperatures reveal that not only were the numbers higher than ever recorded in many places around the world, but the deviation from the norm was also astonishingly large.<\/p>\n\n\n\n

Michael Mann says it\u2019s the fastest rate of warming for millions<\/em> of years. Naturally, no science journalist thinks to ask him how he could possibly know this?<\/em><\/p>\n\n\n\n

What\u2019s especially concerning, experts say, is that \u201cthe rate of warming over the past century has no precedent as far back as we are able to look, not only hundreds or thousands, but many millions of years,\u201d<\/strong> according to University of Pennsylvania meteorologist Michael Mann\u2019s book \u201cOur Fragile Moment.\u201d<\/p>\n\n\n\n

Think about how impossibly hard it is to know how much the world warmed from say 3,450,000 BC to 3,449,900? I mean in the last 10 million years there are 100,000 whole centuries. How many samples do we need each century from around the world to estimate what the \u201cglobal\u201d rate of warming was in every single century? If we just have three samples from the year 2 million BC, could we really say we knew what the temperature was?<\/p>\n\n\n\n

Here (below) is one estimate of temperatures for the last 50,000 centuries. It\u2019s a wild ride. Really, truly, could anyone say there wasn\u2019t one century that warmed faster than our last one?<\/p>\n\n\n\n

Has Michael Mann found an unknown trove of temperature records from Australopithecus<\/em><\/a> onward, or was it just a moment of mad arrogance fueled by 30 years of propaganda?<\/p>\n\n\n\n
