Thus, fantasizing about what would happen if the atmosphere was comprised 0 ppm CO2, 1,000,000 ppm CO2, 0 ppm water vapor\u2026are all just untestable, never-observable thought experiments. They cannot be subjected to the scientific method. Thus, they are&nbsp;<strong><a href=\"https:\/\/www.logicallyfallacious.com\/logicalfallacies\/Unfalsifiability\">unfalsifiable<\/a><\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>CO2\u2019s climate effects are undetectable<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Of course, this very unfalsifiable thought experiment is what believers in the CO2-is-the-climate-control-knob narrative rest their case on. But even if we&nbsp;<em>do<\/em>&nbsp;use this imaginary-world premise, the existing models (MODTRAN, HITRAN) that allegedly&nbsp;<em>support<\/em>&nbsp;the CO2-controls-climate orthodoxy actually undermine it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, as Dr. Koutsoyiannis points out in his extensively-referenced paper, the MODTRAN data show that the Earth\u2019s temperature remains at the default greenhouse-effect value if the water vapor scale is adjusted upwards slightly, by just 30%. The greenhouse effect does not \u201ccollapse\u201d as claimed by Lacis et al. disciples \u2013 the control-knob believers.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The HITRAN database also indicates the imaginary-world condition of doubling CO2 from 400 to 800 ppm would only alter the radiation flux at the top of the atmosphere by -1.1%, a hypothetical realization that could not even be detected in future macroscopic measurements (if the atmosphere ever were to reach a CO2 concentration of 800 ppm).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">MODTRAN models further affirm that (1) there is only a 1% temperature difference between either doubling (800 ppm) or halving (200 ppm) the atmospheric CO2 concentration, and (2) the change in the downwelling radiation resulting from an increase from 300 ppm (1900) to 420 ppm (2023) is only 0.5%. These tiny changes \u201ccould not be discerned by observations.\u201d<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"723\" height=\"422\" data-attachment-id=\"351062\" data-permalink=\"https:\/\/climatescience.press\/?attachment_id=351062\" data-orig-file=\"https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2024\/11\/0Greenhouse-effect-ruled-by-water-vapor-and-cloud-CO2-elicits-only-a-1-percent-perturbation-when-halved-or-doubled-Koutsoyiannis-2024.jpg?fit=1391%2C813&amp;ssl=1\" data-orig-size=\"1391,813\" 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;1&quot;}\" data-image-title=\"0Greenhouse-effect-ruled-by-water-vapor-and-cloud-CO2-elicits-only-a-1-percent-perturbation-when-halved-or-doubled-Koutsoyiannis-2024\" data-image-description=\"\" data-image-caption=\"\" data-large-file=\"https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2024\/11\/0Greenhouse-effect-ruled-by-water-vapor-and-cloud-CO2-elicits-only-a-1-percent-perturbation-when-halved-or-doubled-Koutsoyiannis-2024.jpg?fit=723%2C422&amp;ssl=1\" src=\"https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2024\/11\/0Greenhouse-effect-ruled-by-water-vapor-and-cloud-CO2-elicits-only-a-1-percent-perturbation-when-halved-or-doubled-Koutsoyiannis-2024.jpg?resize=723%2C422&#038;ssl=1\" alt=\"\" class=\"wp-image-351062\" srcset=\"https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2024\/11\/0Greenhouse-effect-ruled-by-water-vapor-and-cloud-CO2-elicits-only-a-1-percent-perturbation-when-halved-or-doubled-Koutsoyiannis-2024.jpg?resize=1024%2C598&amp;ssl=1 1024w, https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2024\/11\/0Greenhouse-effect-ruled-by-water-vapor-and-cloud-CO2-elicits-only-a-1-percent-perturbation-when-halved-or-doubled-Koutsoyiannis-2024.jpg?resize=300%2C175&amp;ssl=1 300w, https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2024\/11\/0Greenhouse-effect-ruled-by-water-vapor-and-cloud-CO2-elicits-only-a-1-percent-perturbation-when-halved-or-doubled-Koutsoyiannis-2024.jpg?resize=768%2C449&amp;ssl=1 768w, https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2024\/11\/0Greenhouse-effect-ruled-by-water-vapor-and-cloud-CO2-elicits-only-a-1-percent-perturbation-when-halved-or-doubled-Koutsoyiannis-2024.jpg?resize=1200%2C701&amp;ssl=1 1200w, https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2024\/11\/0Greenhouse-effect-ruled-by-water-vapor-and-cloud-CO2-elicits-only-a-1-percent-perturbation-when-halved-or-doubled-Koutsoyiannis-2024.jpg?w=1391&amp;ssl=1 1391w\" sizes=\"auto, (max-width: 723px) 100vw, 723px\" \/><figcaption class=\"wp-element-caption\">Image Source:\u00a0<strong><a href=\"https:\/\/doi.org\/10.53234\/scc202411\/01\">Koutsoyiannis, 2024<\/a><\/strong><\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>CO2 has not been detectably reducing the outgoing longwave radiation<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As a \u201ccontrol knob\u201d for the climate, CO2 is believed to be the principal reason why the Earth\u2019s outgoing longwave radiation (OLR) should be reducing (<strong><a href=\"https:\/\/www.mdpi.com\/2072-4292\/10\/10\/1539\">Dewitte and Clerbaux, 2018<\/a><\/strong>).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><em>\u201c\u2026the increase of Greenhouse Gasses (GHG) primarily CO2 reduces the OLR\u201d<\/em><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, despite the increase in CO2 concentration in recent decades, OLR has been increasing.
