Smith made an intriguing comment on the occasion of Summer Solstice (NH) and Winter Solstice (SH):<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cThis is the time when the sun stops the apparent drift in the sky toward one pole, reverses, and heads toward the other. For about 2 more months, temperatures lag this change of trend. That is the total heat storage capacity of the planet. Heat is not stored beyond that point and there can not be any persistent warming as long as winter brings a return to cold.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">I\u2019d actually assert that there are only two measurements needed to show the existence or absence of global warming. Highs in the hottest month must get hotter and lows in the coldest month must get warmer. BOTH must happen, and no other months matter as they are just transitional.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">I\u2019m also pretty sure that the comparison of dates of peaks between locations could also be interesting. If one hemisphere is having a drift to, say, longer springs while the other is having longer falls, that\u2019s more orbital mechanics than CO2 driven and ought to be reflected in different temperature trends \/ rates of drift.\u201d Source:<a href=\"https:\/\/chiefio.wordpress.com\/2015\/06\/21\/summer-solstice-is-here\/\"><strong>\u00a0Summer Solstice is here<\/strong><\/a>\u00a0at chiefio<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"478\" height=\"332\" data-attachment-id=\"291986\" data-permalink=\"https:\/\/climatescience.press\/?attachment_id=291986\" data-orig-file=\"https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2023\/12\/image-469.png?fit=478%2C332&amp;ssl=1\" data-orig-size=\"478,332\" 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-469\" data-image-description=\"\" data-image-caption=\"\" data-large-file=\"https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2023\/12\/image-469.png?fit=478%2C332&amp;ssl=1\" src=\"https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2023\/12\/image-469.png?resize=478%2C332&#038;ssl=1\" alt=\"\" class=\"wp-image-291986\" srcset=\"https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2023\/12\/image-469.png?w=478&amp;ssl=1 478w, https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2023\/12\/image-469.png?resize=300%2C208&amp;ssl=1 300w\" sizes=\"auto, (max-width: 478px) 100vw, 478px\" \/><\/figure>\n<\/div>\n\n\n<p class=\"wp-block-paragraph\">Notice that the global temperature tracks with the seasons of the NH. The reason for this is simple. The NH has twice as much land as the Southern Hemisphere (SH). Oceans have greater heat capacity and thus do not change temperatures as much as land does. So every year when there is almost a 4 \u00b0C swing in the temperature of the Earth, it follows the seasons of the NH. This is especially interesting because the Earth gets the most energy from the sun in January presently. That is because of the orbit of the Earth. The perihelion is when the Earth is closest to the sun and that currently takes place in January.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"723\" height=\"380\" data-attachment-id=\"291987\" data-permalink=\"https:\/\/climatescience.press\/?attachment_id=291987\" data-orig-file=\"https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2023\/12\/image-470.png?fit=1200%2C630&amp;ssl=1\" data-orig-size=\"1200,630\" 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-470\" data-image-description=\"\" data-image-caption=\"\" data-large-file=\"https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2023\/12\/image-470.png?fit=723%2C380&amp;ssl=1\" src=\"https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2023\/12\/image-470.png?resize=723%2C380&#038;ssl=1\" alt=\"\" class=\"wp-image-291987\" srcset=\"https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2023\/12\/image-470.png?resize=1024%2C538&amp;ssl=1 1024w, https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2023\/12\/image-470.png?resize=300%2C158&amp;ssl=1 300w, https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2023\/12\/image-470.png?resize=768%2C403&amp;ssl=1 768w, https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2023\/12\/image-470.png?w=1200&amp;ssl=1 1200w\" sizes=\"auto, (max-width: 723px) 100vw, 723px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Observations and Analysis:<br><\/strong><br>At the time my curiosity was piqued by Chiefio\u2019s comment, so I went looking for data to analyze to test his proposition.

In other words, summers are not adding warming more than other seasons. There is no support for concerns over summer heat waves increasing as a pattern.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It is interesting to note that the plateau in temperatures since the 1998 El Nino is matched by winter months cooler than average during that period, leading to my discovering the real reason for lack of warming recently.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The Real Reason for the Pause in Global Warming?<br><\/strong><br>These data suggest warming trends are coming from less cold overnight temperatures as measured at land weather stations. Since stations exposed to urban heat sources typically show higher minimums overnight and in winter months, this pattern is likely\u00a0an artifact of human settlement activity rather than CO2 from fossil fuels.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"600\" height=\"419\" data-attachment-id=\"291989\" data-permalink=\"https:\/\/climatescience.press\/?attachment_id=291989\" data-orig-file=\"https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2023\/12\/image-471.png?fit=600%2C419&amp;ssl=1\" data-orig-size=\"600,419\" 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-471\" data-image-description=\"\" data-image-caption=\"\" data-large-file=\"https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2023\/12\/image-471.png?fit=600%2C419&amp;ssl=1\" src=\"https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2023\/12\/image-471.png?resize=600%2C419&#038;ssl=1\" alt=\"\" class=\"wp-image-291989\" srcset=\"https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2023\/12\/image-471.png?w=600&amp;ssl=1 600w, https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2023\/12\/image-471.png?resize=300%2C210&amp;ssl=1 300w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\" \/><\/figure>\n<\/div>\n\n\n<p class=\"wp-block-paragraph\">Thus the Pause (more correctly the Plateau) in global warming is caused by end of the century&nbsp;completion of urbanization around&nbsp;most surface stations.
