1. Earth's Without-Atmosphere Mean Surface Temperature Calculation.
1. Earth's Without-Atmosphere Mean Surface Temperature Calculation. R = 1 AU, is the Earth's distance from the sun in astronomical units (R = 150.000.000 km, which is Earth's average distance from the sun). Earth’s albedo: aearth= 0,306 Albedo is defined as the diffuse reflected portion of the incident on planet surface solar flux. Earth is a smooth rocky planet, Earth’s surface solar irradiation accepting factor is: Φearth= 0,47 Φ - the planet surface solar irradiation accepting factor (the planet surface spherical shape and the planet surface roughness coefficient). Φ(1 - a) - the planet surface coupled term (it represents the NOT REFLECTED portion of the incident on planet surface solar flux, it is the portion of solar flux which gets in INTERACTION processes with the planet surface). β = 150 days*gr*oC/rotation*cal – ( the Rotational Warming Factor constant ). N = 1 rotation /per day, is Earth’s rate of rotation with reference to the sun. Earth's day equals 24 hours= 1 earthen day.

Air is very thin, and CO2 is a trace gas in a very thin air.
Christos Vournas | May 27, 2025 at 7:34 am | Reply |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 Christos Vournas | May 27, 2025 at 7:41 am | Reply “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 Neolith

I think the ozone doesn’t protect life on Earth
I think the ozone doesn’t protect life on Earth, because ozone is like it is not there – it has a so much small presence – it cannot stop anything. Christos Vournas | May 27, 2025 at 11:47 am | "The ozone layer or ozone shield is a region of Earth's stratosphere that absorbs most of the Sun's ultraviolet radiation. It contains a high concentration of ozone (O3) in relation to other parts of the atmosphere, although still small in relation to other gases in the stratosphere. The ozone layer peaks at 8 to 15 parts per million of ozone,[1] while the average ozone concentration in Earth's atmosphere as a whole is about 0.3 parts per million. The ozone layer is mainly found in the lower portion of the stratosphere, from approximately 15 to 35 kilometers (9 to 22 mi) above Earth, although its thickness varies seasonally and geographically.[2]" For comparison, the trace gas CO2 content in atmosphere is ~ 420 ppm ( ozone is 0,3 ppm, ozone layer peaks at 8 to 15 parts per million of ozone, 8 to
