Its dramatic projections of catastrophe relied heavily on U.N.-sponsored Representative Concentration Pathway 8.5 (RCP8.5) and its successor SSP5-8.5\u2014both extreme predictions of carbon dioxide emissions that were treated as realistic.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As far back as 2017,&nbsp;<a href=\"https:\/\/www.researchgate.net\/publication\/319157132_Why_do_climate_change_scenarios_return_to_coal\" target=\"_blank\" rel=\"noopener\">scientists noted<\/a>&nbsp;the far-fetched nature of the U.N. predictions. In August, the Trump administration proposed an&nbsp;<a href=\"https:\/\/www.noaa.gov\/sites\/default\/files\/2026-08\/NCA5-Proposed-Amendment-August-2026.pdf\" target=\"_blank\" rel=\"noopener\">amendment<\/a>&nbsp;to NCA5 that acknowledges its emission forecasts are implausible and must not guide federal policymaking. This is a welcome restoration of scientific integrity.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The amendment, issued under the U.S. Global Change Research Program and aligned with Executive Order 14303, \u201cRestoring Gold Standard Science,\u201d states that results dependent on RCP8.5, SSP5-8.5, or equivalent emission scenarios \u201cshould not be used as expected, baseline, business-as-usual, likely, central, or policy-relevant federal planning futures.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Any NCA5 figure, table, or claim based on these \u201cimplausible\u201d scenarios must carry an explicit caveat. Projections of damages, health effects, or ecosystem collapse cannot stand alone as policy premises without comparison to plausible alternatives and real-world observations.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This correction is long overdue. RCP8.5 was never designed to forecast the most likely future. It was constructed as an upper-bound for climate-model experiments\u2014an exploratory tool of imaginary, extreme conditions. Its predictions of global warming defied observed trends in growth of coal consumption, technological development, and socioeconomic trajectories, according to multiple peer-reviewed analyses.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Treating extreme emission scenarios as ordinary distorted the entire national climate assessment. It inflated projected impacts, fueled exaggerated risk narratives, and justified costly regulatory interventions that ignored economics and human welfare. The amendment properly requires that such results be contextualized or set aside for decision-making.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Yet this amendment, while necessary, is only a first step. NCA5\u2019s deeper problems remain. It continues to lean on climate models that have systematically overestimated warming and failed basic observational tests. It elevates politically driven documents of the U.N.\u2019s Intergovernmental Panel on Climate Change over scientific data. Most critically, it omits the extraordinary benefits of rising atmospheric CO<sub>2<\/sub>&nbsp;and of the fossil fuels that produce it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Carbon dioxide is not a pollutant; it is the essential plant food that makes life on Earth possible. Current concentrations, near 420 parts per million, remain far below levels that have prevailed for much of Earth\u2019s history and are still low for optimal plant growth. Decades of laboratory and field evidence demonstrate that elevated CO<sub>2<\/sub>&nbsp;increases photosynthetic rates, improves water-use efficiency, and boosts crop yields\u2014wheat by 20% to 30% and soybeans by up to 46% under controlled conditions. Satellite observations confirm global greening, with rising CO<sub>2<\/sub>&nbsp;responsible for most of the increase in leaf area across vast regions. Nitrogen fertilizers derived from fossil fuels support roughly half the world\u2019s population.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Without affordable energy and the CO<sub>2<\/sub>&nbsp;fertilization effect, feeding 8 billion people becomes far more difficult.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Modest warming itself brings many benefits, including longer growing seasons in temperate zones, reduced cold-related mortality (which exceeds deaths from heat), and expanded habitable ranges. Trends of weather-driven disasters\u2014hurricanes, tornadoes, wildfires\u2014do not match the alarmist storyline when examined against long-term records rather than model outputs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The real catastrophe would come from policies that deliberately restrict reliable energy in pursuit of net zero. Such policies raise energy costs, harm the poor, slow development in the Global South, and risk food insecurity by limiting fertilizers and mechanization.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">True gold-standard science demands that we begin with observations, test models against data, disclose assumptions transparently, and weigh risks and benefits. Future assessments must evaluate every emission scenario on empirical grounding, not institutional pedigree. They must acknowledge that humanity\u2019s use of fossil fuels has lifted billions from poverty while restoring CO<sub>2<\/sub>&nbsp;to levels that enhance the biosphere.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Validating what rigorous scientists have documented for years, the proposed NCA5 amendment is progress. Now, policymakers should seize this moment to reassess the entire report against observations, restore balance by including the benefits of CO<sub>2<\/sub>, and reject fearmongering that has driven policy for too long.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Energy abundance, a greener planet, and prosperity can be celebrated and advanced further through the application of science when ideology is set aside.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Originally published in&nbsp;<em><a href=\"https:\/\/www.dailywire.com\/news\/why-net-zero-policies-risk-greater-human-catastrophe-than-carbon-dioxide?author=Angela+Wheeler&amp;category=DW+Opinion&amp;elementPosition=0&amp;row=3&amp;rowHeadline=Opinion+Board&amp;rowType=Article+Carousel&amp;title=Why+Net-Zero+Policies+Risk+Greater+Human+Catastrophe+Than+Carbon+Dioxide\" target=\"_blank\" rel=\"noopener\">Daily Wire<\/a><\/em>&nbsp;on September 1, 2026<em>.<\/em><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><em><a href=\"https:\/\/co2coalition.org\/teammember\/angela-wheeler\/\" target=\"_blank\" rel=\"noopener\">Angela Wheeler<\/a>&nbsp;is executive director of the&nbsp;<\/em><a href=\"https:\/\/co2coalition.org\/\" target=\"_blank\" rel=\"noopener\"><em>CO<sub>2<\/sub><\/em><em>&nbsp;Coalition<\/em><\/a><em>, Fairfax, Virginia.
