Yeah, that\u2019s got nothing on the Carnian pluvial event, otherwise known as the 1 to 2 million-year stretch of Earth\u2019s history where a solid chance of rain was the rule, not the exception.<\/p>\n<h2>What happened during the Carnian pluval event?<\/h2>\n<p>It all started around 232 million years ago when, like the downpour that follows a long, hot summer, unusually heavy and persistent rain brought an end to one of Earth\u2019s dry spells.\u00a0<\/p>\n<p>At the time, the planet\u2019s continents were smooshed into the supercontinent <a href=\"https:\/\/www.iflscience.com\/tags\/pangaea\" target=\"_blank\" rel=\"noopener\">Pangaea<\/a>, which was already prone to monsoons. The sea temperature was akin to \u201chot soup\u201d, paleoenvironment researcher Paul Wignall told <a href=\"https:\/\/www.newscientist.com\/article\/mg22730300-600-travel-back-in-time-to-the-most-extreme-desert-and-monsoons-ever\/\" target=\"_blank\" rel=\"noopener\">New Scientist<\/a>, meaning there was already a lot of moisture kicking about in the air to make a monsoon.<\/p>\n<p>So, what triggered things to get even wetter? Unlike the usual end to a hot summer, some have <a href=\"https:\/\/www.science.org\/doi\/10.1126\/sciadv.aba0099\" target=\"_blank\" rel=\"noopener\">suggested<\/a> it was down to a series of huge volcanic eruptions that took place on the Wrangellia Terrane, which nowadays sits along the coast of Alaska and British Columbia.<\/p>\n<p>Volcanic eruptions are known to mess with the level of water vapor in the stratosphere \u2013 it happened after the recent <a href=\"https:\/\/www.iflscience.com\/tonga-eruption-filled-the-atmosphere-with-water-potentially-damaging-the-ozone-layer-64651\" target=\"_blank\" rel=\"noopener\">Hunga Tonga-Hunga Ha\u2019apai eruption<\/a> \u2013 and according to geoscientist Jacopo Dal Corso, Wrangellia eruptions were peaking during the Carnian.<\/p>\n<p>&#8220;I was studying the geochemical signature of the eruptions a few years ago and identified some massive effects on the atmosphere worldwide,\u201d Dal Corso told <a href=\"https:\/\/blog.everythingdinosaur.com\/blog\/_archives\/2020\/09\/17\/carnian-pluvial-episode-late-triassic-mass-extinction.html\" target=\"_blank\" rel=\"noopener noreferrer\">Everything Dinosaur<\/a>. \u201cThe eruptions were so huge, they pumped vast amounts of greenhouse gases like carbon dioxide and there were spikes of global warming.\u201d<\/p>\n<p>One of the consequences of all this rain is thought to have been a period of increased extinction for the life on Earth at the time, particularly for marine creatures like ammonoids, conodonts, and crinoids \u2013 but it might have also set the stage for new life, particularly when it came to <a href=\"https:\/\/www.iflscience.com\/fly-over-the-worlds-longest-continuous-dinosaur-tracks-in-spectacular-new-drone-footage-76307\" target=\"_blank\" rel=\"noopener\">dinosaurs<\/a>.<\/p>\n<p>In a study published in the <a href=\"https:\/\/doi.org\/10.1144\/jgs2018-049\" target=\"_blank\" rel=\"noopener\">Journal of the Geological Society<\/a>, one team of researchers wrote that &#8220;In the wake of wide extinctions of plants and key herbivores on land, the dinosaurs were seemingly the main beneficiaries in the time of recovery, expanding rapidly in diversity, ecological impact (relative abundance) and regional distribution, from South America initially, to all continents.&#8221;<\/p>\n<h2>How do we know it happened?<\/h2>\n<p>The first evidence of the Carnian pluvial event came courtesy of geologists in the 1980s, most prominently the UK duo of Alastair Ruffell and Michael Simms. Ruffell had identified a stripe of grey running through the red stone of Somerset\u2019s Lipe Hill, a feature that indicated the region had gone from a period of intense dryness to seriously wet.<\/p>\n<p>However, when Ruffell, alongside Simms, published a study saying as much \u2013 there was also evidence from Germany, the US, and the Himalayas \u2013 it wasn\u2019t taken very seriously.<\/p>\n<p>\u201cI remember one or two quite senior academics thought it was a preposterous idea,\u201d Simms told <a href=\"https:\/\/media.nature.com\/original\/magazine-assets\/d41586-019-03699-7\/d41586-019-03699-7.pdf\" target=\"_blank\" rel=\"noopener\">Nature<\/a>.<\/p>\n<p>While Ruffell and Simms moved on to other things, over the years, the evidence to support their theory slowly began to stack up.\u00a0<\/p>\n<p>Now, this area of research is so popular that there\u2019s even been a conference dedicated to it.<\/p>\n<\/div>\n<p><script async src=\"https:\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-3711241968723425\"\r\n     crossorigin=\"anonymous\"><\/script>\r\n<ins class=\"adsbygoogle\"\r\n     style=\"display:block\"\r\n     data-ad-format=\"fluid\"\r\n     data-ad-layout-key=\"-fb+5w+4e-db+86\"\r\n     data-ad-client=\"ca-pub-3711241968723425\"\r\n     data-ad-slot=\"7910942971\"><\/ins>\r\n<script>\r\n     (adsbygoogle = window.adsbygoogle || []).push({});\r\n<\/script><br \/>\n<br \/><div data-type=\"_mgwidget\" data-widget-id=\"1660802\">\r\n<\/div>\r\n<script>(function(w,q){w[q]=w[q]||[];w[q].push([\"_mgc.load\"])})(window,\"_mgq\");\r\n<\/script>\r\n<br \/>\n<br \/><a href=\"https:\/\/www.iflscience.com\/when-earth-endured-two-million-years-of-rain-the-carnian-pluvial-event-76438\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>You know those days where it feels like it just hasn\u2019t stopped raining?
