The Holocene glacial retreat
"The Holocene glacial retreat is a geographical phenomenon that involved the global retreat of glaciers (deglaciation) that previously had advanced during the Last Glacial Maximum. Ice sheet retreat initiated ca. 19,000 years ago and accelerated after ca. 15,000 years ago. The Holocene, starting with abrupt warming 11,700 years ago, resulted in rapid melting of the remaining ice sheets of North America and Europe." https://en.wikipedia.org/wiki/Holocene_glacial_retreat

The early Holocene sea level rise (EHSLR)
“The early Holocene sea level rise (EHSLR) was a significant jump in sea level by about 60 m (197 ft) during the early Holocene, between about 12,000 and 7,000 years ago, spanning the Eurasian Mesolithic.[1] The rapid rise in sea level and associated climate change, notably the 8.2 ka cooling event (8,200 years ago), and the loss of coastal land favoured by early farmers, may have contributed to the spread of the Neolithic Revolution to Europe in its Neolithic period.[2]” https://en.wikipedia.org/wiki/Early_Holocene_sea_level_rise

Gases planets Mean Temps Calculations at 1 bar level

So = 1.361 W/m² is Solar constant Jupiter’s albedo, ajupiter = 0,503 Jupiter is a gaseous planet, Jupiter’s surface irradiation accepting factor Φjupiter = 1 (Jupiter has not surface to reflect the incident sunlight.

The Te = 255K is a mathematical abstraction
The Te = 255K is a mathematical abstraction Let's say it is a correct assertion the Tmean - Te = 288K -255K = 33°C, (which is of course not, because there is not such a thing as Te, because it is a pure theoretical abstraction)... But let's say it is correct, and there is a 33°C atmospheric greenhouse effect on Earth's surface. And the 420 ppm - 280 ppm = 140 ppm of CO2 had risen the average surface temperature by 1,5°C since predindustrial 1850 average surface temperature. - But the assertion doesn't align with the numbers. Let's explain: If the 140 ppm caused a 1,5°C rise in Global temperature, then the predindustrial 280 ppm of CO2 had to be a cause of 3°C from the Te = 255K, so there should be by now the average surface temperature of our planet Earth 255K + 3°C + 1,5°C = 260K... But it is 288K. And 288K - 260K = 28°C. The 28°C difference where to be attributed then? - But there is another greenhouse gas with average 3% content in atmosphere, which is 30000 ppm. Ok, 30000 ppm /28°C

A trace gas CO2 doesn’t warm Earth’s surface
There is as much CO2 content in atmosphere as Earth’s system permits at given temperature.. Let’s say, we had a technology and suddenly removed the entire CO2 from atmosphere… In a while, the Earth’s system would replace the removed 420 ppm – and everything wiil be back to normal. The oceans is an enormous reservoir of CO2. There is nothing we can do against it. But what for the effort? A trace gas CO2 doesn’t warm Earth’s surface.
