His piece asserts that human-caused warming is driving stronger storms, citing rapid intensification in specific cases like Hurricane Milton (which reached 185 mph winds) and even speculating about the need for a hypothetical \u201cCategory 6\u201d classification.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">Indeed Milton nearly breached the threshold of 192 mph sustained winds argued by one recent study to&nbsp;<a href=\"https:\/\/www.pnas.org\/doi\/10.1073\/pnas.2322597121\">constitute a whole new \u201ccategory six\u201d<\/a>&nbsp;caliber of hurricanes that has emerged in an era of unprecedented ocean warmth. A separate study estimated that the deadly flooding in the southeastern U.S. from hurricane Helene was i<a href=\"https:\/\/weather.com\/news\/climate\/news\/2024-10-01-climate-change-rainfall-flooding-helene\">ncreased by 50%<\/a>&nbsp;by human-caused warming.<br><br><a href=\"https:\/\/michaelmann.net\/content\/reflections-2024-atlantic-hurricane-season\">https:\/\/michaelmann.net\/content\/reflections-2024-atlantic-hurricane-season<\/a><\/p>\n<\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">However, these claims about stronger hurricanes don\u2019t align with the latest findings from the IPCC. The 6th Assessment Report (AR6) explicitly states that evidence for long-term trends in hurricane frequency and intensity is inconclusive, with no detectable increase in global cyclone frequency and mixed regional trends. While short-term variability may yield extreme seasons, the broader picture contradicts Mann\u2019s insistence that climate change is creating reliably stronger storms. His narrative relies on cherry-picking extreme cases rather than examining the full record.<\/p>\n\n\n\n<div data-wp-interactive=\"core\/file\" class=\"wp-block-file\"><object data-wp-bind--hidden=\"!state.hasPdfPreview\" hidden class=\"wp-block-file__embed\" data=\"https:\/\/climatescience.press\/wp-content\/uploads\/2025\/01\/Page-90_-from-IPCC_AR6_WGI_Chapter12highlight.pdf\" type=\"application\/pdf\" style=\"width:100%;height:600px\" aria-label=\"Embed of ,Page-90_-from-IPCC_AR6_WGI_Chapter12highlight.\"><\/object><a id=\"wp-block-file--media-dc0972ca-c5f5-4aa0-aa21-4701df0ac8cd\" href=\"https:\/\/climatescience.press\/wp-content\/uploads\/2025\/01\/Page-90_-from-IPCC_AR6_WGI_Chapter12highlight.pdf\">,Page-90_-from-IPCC_AR6_WGI_Chapter12highlight<\/a><a href=\"https:\/\/climatescience.press\/wp-content\/uploads\/2025\/01\/Page-90_-from-IPCC_AR6_WGI_Chapter12highlight.pdf\" class=\"wp-block-file__button wp-element-button\" download aria-describedby=\"wp-block-file--media-dc0972ca-c5f5-4aa0-aa21-4701df0ac8cd\">Herunterladen<\/a><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">This misalignment extends to his forecasts. Mann and his team predicted an \u201cextremely active\u201d hurricane season, with a most likely estimate of 33 named storms. Instead, the season produced just 18\u2014or 19 if we generously include a borderline case.<strong>&nbsp;For perspective, this falls well below Mann\u2019s projected range of 27\u201339 storms. Not exactly the \u201crecord-shattering\u201d season anticipated.<\/strong><\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>The Excuses: Blame the Variables, Ignore the Model<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Rather than owning the shortcomings of their forecasts, Mann and his colleagues turn to a familiar playbook: citing unpredictable variables to explain their miss. They blame the Madden-Julian Oscillation (MJO)\u2014a well-known atmospheric cycle\u2014for suppressing storm formation during the crucial July and August peak. Saharan dust outbreaks are also invoked as a contributing factor.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">So there\u2019s no real discrepancy when it comes to the latter half of the season. It was basically as active as predicted. The puzzle is why July and August were so quiet despite clearly favorable seasonal large-scale climate conditions. This is where one runs into complications with intraseasonal variability. Of particular relevance is the so-called&nbsp;<a href=\"https:\/\/www.climate.gov\/news-features\/blogs\/enso\/what-mjo-and-why-do-we-care\">Madden-Julian oscillation<\/a>&nbsp;or simply \u201cMJO\u201d to its friends. The MJO is a roughly 40-50 day oscillation in the tropical atmospheric circulation which influences the location of convection, which shifts east and west over the course of a single 40-50 day cycle. When the center of convection coincides with the tropical Atlantic, conditions are more favorable for tropical cyclogenesis.<br><br><a href=\"https:\/\/michaelmann.net\/content\/reflections-2024-atlantic-hurricane-season\">https:\/\/michaelmann.net\/content\/reflections-2024-atlantic-hurricane-season<\/a><\/p>\n<\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">While these factors undoubtedly play a role, they are hardly \u201cunknowns.\u201d Both phenomena have long been recognized as influential in tropical weather. Shouldn\u2019t a sophisticated statistical model, touted as one of the \u201cmost accurate,\u201d account for such routine variability? Mann\u2019s reliance on these explanations reads less as scientific insight and more as retroactive justification.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Alternative Models: When One Forecast Fails, Pivot to Another<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">In a curious twist, Mann highlights an alternative model that predicted 19.9 storms\u2014a remarkably close match to the observed total. Yet he admits that this model is generally less reliable than the one that failed spectacularly. Touting the success of a secondary, less accurate framework seems like an exercise in hedging bets rather than improving the science. If your \u201cbackup\u201d prediction worked better, why not use it as the primary model going forward? This sleight-of-hand raises more questions than it answers.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">There is one other noteworthy detail here. Our group makes an alternative forecast in which tropical sea surface temperature (SST) in the main development region (MDR) is replaced with what we call \u201crelative SST\u201d, defined as the difference between MDR SST and the average SST throughout the entire tropics, which some researchers have argued might be a better predictor of Atlantic hurricane activity. While&nbsp;<a href=\"https:\/\/agupubs.onlinelibrary.wiley.com\/doi\/full\/10.1029\/2011JD017170\">our previous analyses<\/a>&nbsp;have found that this alternative model yields less skillful predictions, it is notable that this year<a href=\"https:\/\/web.sas.upenn.edu\/mannresearchgroup\/highlights\/highlights-2024hurricane\/\">&nbsp;it yielded<\/a>&nbsp;a much more accurate prediction of 19.9 +\/- 4.5 total named storms that was remarkably close to the seasonal total.<\/p>\n<\/blockquote>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Stronger Hurricanes? Not So Fast<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">A particularly bold claim in Mann\u2019s reflection is that human-caused warming is directly responsible for the rapid intensification and increased destructiveness of storms. He points to Milton and Helene as evidence, even citing studies that argue for the necessity of a new \u201cCategory 6\u201d hurricane classification.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, this narrative overlooks the IPCC\u2019s cautious stance on the issue. The IPCC AR6 finds only low confidence in detectable increases in hurricane intensity globally. While there is moderate confidence in increased peak wind speeds for a subset of tropical cyclones, these trends are not consistently observed across all ocean basins. Moreover, the number of global cyclones has either decreased or remained flat. Mann\u2019s narrative about a world of ever-stronger storms is more rhetorical than rigorously scientific.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Here is the reality of Tropical Cyclone trends from Roger Pielke Jr, and Ryan Maue<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">\u201cWe have identified considerable interannual variability in the frequency of global hurricane landfalls; but within the resolution of the available data, our evidence does not support the presence of significant long-period global or individual basin linear trends for minor, major, or total hurricanes within the period(s) covered by the available quality data.\u201d<\/p>\n<\/blockquote>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"661\" height=\"430\" data-attachment-id=\"363736\" data-permalink=\"https:\/\/climatescience.press\/?attachment_id=363736\" data-orig-file=\"https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2025\/01\/image-759.png?fit=661%2C430&amp;ssl=1\" data-orig-size=\"661,430\" 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=\"image\" data-image-description=\"\" data-image-caption=\"\" data-large-file=\"https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2025\/01\/image-759.png?fit=661%2C430&amp;ssl=1\" src=\"https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2025\/01\/image-759.png?resize=661%2C430&#038;ssl=1\" alt=\"\" class=\"wp-image-363736\" srcset=\"https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2025\/01\/image-759.png?w=661&amp;ssl=1 661w, https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2025\/01\/image-759.png?resize=300%2C195&amp;ssl=1 300w\" sizes=\"auto, (max-width: 661px) 100vw, 661px\" \/><\/figure>\n<\/div>\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"720\" height=\"354\" data-attachment-id=\"363737\" data-permalink=\"https:\/\/climatescience.press\/?attachment_id=363737\" data-orig-file=\"https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2025\/01\/image-760.png?fit=720%2C354&amp;ssl=1\" data-orig-size=\"720,354\" 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=\"image\" data-image-description=\"\" data-image-caption=\"\" data-large-file=\"https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2025\/01\/image-760.png?fit=720%2C354&amp;ssl=1\" src=\"https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2025\/01\/image-760.png?resize=720%2C354&#038;ssl=1\" alt=\"\" class=\"wp-image-363737\" srcset=\"https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2025\/01\/image-760.png?w=720&amp;ssl=1 720w, https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2025\/01\/image-760.png?resize=300%2C148&amp;ssl=1 300w\" sizes=\"auto, (max-width: 720px) 100vw, 720px\" \/><figcaption class=\"wp-element-caption\"><a href=\"https:\/\/rogerpielkejr.substack.com\/p\/just-the-facts-on-global-hurricanes\">https:\/\/rogerpielkejr.substack.com\/p\/just-the-facts-on-global-hurricanes<\/a><\/figcaption><\/figure>\n<\/div>\n\n\n<h4 class=\"wp-block-heading\"><strong>Broader Implications: Science or Spin?<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Mann\u2019s post inadvertently highlights a key issue in climate science: the gap between predictive confidence and observed outcomes. When forecasts fail, climate scientists often claim the climate system is no longer behaving predictably\u2014implying their models are still right, just incapable of adapting to a \u201cchanging system.\u201d This raises a critical question:&nbsp;<strong>If the system is behaving unpredictably, how can forecasts demand such unwavering trust, let alone justify sweeping climate policies?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Mann\u2019s reflection ends with an ominous flourish: \u201cThere could well be far more unpleasant surprises in the greenhouse.\u201d While such warnings are useful for grabbing headlines, they risk undermining public confidence when paired with unfulfilled predictions. If we\u2019re not sure what to expect, how can anyone claim certainty about the impacts of climate change? This is less science and more speculative storytelling.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Final Thoughts: Missed Marks and Moving Goalposts<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The 2024 Atlantic hurricane season wasn\u2019t the catastrophe Mann\u2019s models forecasted. While the storms that did form were destructive, the season as a whole fell far short of expectations. This raises a critical issue: When predictions fail, should we be refining models or doubling down on fear-driven narratives?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Mann\u2019s reflections suggest the latter approach. His insistence that missed forecasts still \u201cteach us important lessons\u201d sidesteps the more obvious conclusion: overconfidence in flawed models does more harm than good. Rather than admitting these forecasts have limits, he suggests the rules of the climate system itself may be changing. It\u2019s a convenient excuse but an unconvincing one.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For climate science to have any credibility, it needs to grapple honestly with its uncertainties\u2014not reframe every miss as proof of an unknowable, ever-shifting reality. Until then, one can\u2019t help but see this as another chapter in the growing credibility crisis of climate forecasting.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>This misalignment extends to his forecasts.
