Climate researchers and critics had pointed out its improbability as early as 2017, citing limitations such as global coal resources and population growth assumptions. The widespread reliance on this false scenario led to costly regulations, economic consequences, and psychological impacts, especially on younger generations. The article criticizes how science was manipulated for political and ideological aims, highlighting efforts by organizations like the American Energy Institute to expose the misuse of RCP8.5 and urging the scientific community and policymakers to rescind laws built on its flawed projections.  <\/p>\n<p class=\"readmore\">\n    <button onclick=\"showReadMore()\" id=\"readmorebtn\">Read more&#8230;<\/button>\n<\/p>\n<hr id=\"line\">\n<span id=\"more\"><br \/>\n<!DOCTYPE html PUBLIC \"-\/\/W3C\/\/DTD HTML 4.0 Transitional\/\/EN\" \"http:\/\/www.w3.org\/TR\/REC-html40\/loose.dtd\"><br \/>\n<?xml encoding=\"utf-8\" ?><?xml encoding=\"utf-8\" ?><?xml encoding=\"utf-8\" ?><?xml encoding=\"utf-8\" ?><?xml encoding=\"utf-8\" ?><?xml encoding=\"utf-8\" ?><?xml encoding=\"utf-8\" ?><?xml encoding=\"utf-8\" ?><?xml encoding=\"utf-8\" ?><?xml encoding=\"utf-8\" ?><?xml encoding=\"utf-8\" ?><?xml encoding=\"utf-8\" ?><?xml encoding=\"utf-8\" ?><?xml encoding=\"utf-8\" ?><?xml encoding=\"utf-8\" ?><?xml encoding=\"utf-8\" ?><?xml encoding=\"utf-8\" ?><html><body><\/p>\n<section> \t\t\t\t<script>console.log(\"ad slot (AC1)\")<\/script><script>console.log(\"ad slot (IC1)\")<\/script><script>console.log(\"ad slot (IC2)\")<\/script><script>console.log(\"ad slot (IC3)\")<\/script><script>console.log(\"ad slot (IC4)\")<\/script><script>console.log(\"ad slot (REP_0)\")<\/script><\/p>\n<p>In late April, the U.N. Intergovernmental Panel on Climate Change admitted that Representative Concentration Pathway 8.5, or RCP8.5, the high-emissions climate model scenario that dominated climate research and policy, was \u201cimplausible.\u201d<\/p>\n<p>This represented a tidal wave in the climate science and policy community. For more than a decade, the IPCC has treated RCP8.5 as the \u201cbusiness-as-usual\u201d pathway, projecting global temperatures to rise by 4.3\u2103 or more by 2100 with all manner of \u201cend of the world\u201d results.<\/p>\n<p>The IPCC has wielded RCP8.5 like a cudgel during treaty negotiations to beat government climate negotiators into multiple unjustified climate treaties restricting the use of fossil fuels.<\/p>\n<p>The fact that RCP8.5 was \u201cimplausible\u201d should have come as no surprise because many climate researchers were on the record noting from the outset that RCP8.5 was very unlikely and shouldn\u2019t be treated as expected or business as usual. Yet that didn\u2019t stop the vast majority of scientists publishing in the <a href=\"https:\/\/www.conservativenewsdaily.net\/breaking-news\/cdc-director-i-have-been-completely-forthcoming-about-mask-mandates\/\" title=\"CDC Director: \u2018I Have Been Completely Forthcoming\u2019 About Mask Mandates\">peer-reviewed literature<\/a> and speaking to the mainstream media from treating it as such, calling on government leaders to impose a rapid transition away from fossil fuels in order to prevent the disastrous social, economic, and environmental outcomes that RCP8.5 forecast.<\/p>\n<p>The Heartland Institute critiqued RCP8.5 from the start, noting it was not just implausible, but likely impossible, as far back as 2017. It was debunked in detail in Climate Change Reconsidered II: Fossil Fuels in 2019.<\/p>\n<p>So, concerning the IPCC\u2019s belated admission, in the immortal words of celluloid Die Hard hero John McClane, \u201cWelcome to the party, pal.\u201d<\/p>\n<p>Better late than never.<\/p>\n<p>Sadly, in the interim from the time RCP8.5 was officially released as \u201cbusiness as usual\u201d to the IPCC\u2019s recent mea culpa, tens of thousands of peer-reviewed climate studies used RCP8.5. By early 2020 alone, researchers were publishing roughly 20 studies per day using it, with estimates exceeding 8,500 papers in an 18-month period.<\/p>\n<p>There were many reasons to consider RCP8.5 a false rallying point for climate policy from its inception, foremost among them perhaps being the fact that not enough recoverable coal exists in the world to produce the assumed fivefold increase in use by 2100.<\/p>\n<p>In addition, the human population is not under any foreseeable track to increase to the 12.6 billion to 14.5 billion range assumed in the RCP8.5 scenario.<\/p>\n<p>The IPCC and the lapdog media are treating this conclusion like it\u2019s a new discovery, but it is not. RCP8.5\u2019s implausibility, indeed impossibility, was known to its promoters from the start, but instead of jettisoning it, they built a massive edifice of publications, laws, and regulations based upon its false predictions.<\/p>\n<p>In this, they simply followed the advice of an early climate alarmist, the late Dr. Stephen Schneider, who admitted that being honest about the science would undercut efforts to get governments to enact the policy prescriptions alarmists desired.<\/p>\n<p>\u201cOn the one hand, as scientists we are ethically bound to the scientific method, in effect promising to tell the truth, the whole truth, and nothing but \u2014 which means that we must include all doubts, the caveats, the ifs, ands and buts,\u201d Schneider told Discover magazine. \u201cOn the other hand, we are not just scientists but human beings as well, and like most people we\u2019d like to see the world a better place, which in this context translates into our working to reduce the risk of potentially disastrous <a href=\"https:\/\/www.conservativenewsdaily.net\/breaking-news\/elon-musk-i-got-a-covid-test-four-times-in-one-day-two-came-back-negative-two-came-back-positive-the-daily-wire\/\" title=\"Elon Musk: I Got A COVID Test Four Times In One .... \u2018Two Came Back Negative, Two Came Back Positive.\u2019 | The Daily Wire\">climate change<\/a>.\u201d<\/p>\n<p>\u201cTo do that we need to get some broad-based support, to capture the public\u2019s imagination, [which] of course, means getting loads of media coverage, so we have to offer up scary scenarios, make simplified, dramatic statements, and make little mention of any doubts we might have,\u201d Schneider continued.<\/p>\n<p>Science, as a way of expanding knowledge and discovering truths, is undermined when its practitioners practice Plato\u2019s art of the (ig)noble lie in the pursuit of political ends. That\u2019s just what the IPCC and its fellow travelers have been doing.<\/p>\n<p>Recently, the American Energy Institute, headed by the Hon. Jason Isaac, created an entire website, \u201cThey-knew.com,\u201d dedicated to bringing to light the whole sordid RCP8.5 scandal.<\/p>\n<p>They-Knew.com is a comprehensive public record documenting the systematic misuse of RCP8.5, which powered nearly every alarmist headline, regulation, court filing, and school curriculum on climate change since 2011.<\/p>\n<p>As Isaac points out in a press release, \u201cScientists flagged RCP8.5 as unrealistic as early as 2017, published those warnings in the world\u2019s most prestigious journals, and watched as governments, central banks, courts, educators, and advocacy organizations kept using it anyway. That makes RCP8.5\u2019s promotion and seemingly continued use \u2014 since its repudiation by the IPCC RCP8.5 has been used as a reference case in more than 70 peer-reviewed articles \u2014 one of the most consequential scientific integrity failures of the century.\u201d<\/p>\n<p>They-knew.com documents the organizations and individual power brokers in both the public and private sectors who used RCP8.5 to push flawed, costly, liberty-crushing laws, regulations, and economic policies.<\/p>\n<p>Aside from lost jobs, mounting public debt, squandered and wasted resources, and reduced consumer freedom resulting from the counterproductive energy policies premised on RCP8.5, arguably the most damaging long-term impact of its promotion was its use to scare a generation of children into the belief that the world was ending because of their and their parents\u2019 energy choices. Kids have experienced unnecessary anxiety, misplaced guilt, unjustified outrage, and psychological harm as a result of the blind promotion of RCP8.5\u2019s apocalyptic projections as truth.<\/p>\n<p>In the aftermath of RCP8.5\u2019s public downfall, the only honest thing to do scientifically would be to withdraw from publication the tens of thousands of articles relying on this modern day Piltdown man hoax.<\/p>\n<p>Politically, the only honest and honorable result of this whole fiasco would be to rescind every treaty, law, and regulation enacted to prevent the harms forecast by the false RCP8.5 \u2014 harms that we now know, if we didn\u2019t before, were never realistic.<\/p>\n<\/p>\n<p><i><b>The views expressed in this opinion article are those of their author and are not necessarily either d or endorsed by the owners of this website.
