Temperature in the Venusian troposphere increases linearly with altitude. At an altitude of 50km in the Venusian atmosphere, the temperature is about the same as at Earth’s surface.
At an altitude of 50km in the Venusian atmosphere, the pressure is also about the same as the earth’s surface.
What this demonstrates is that planetary temperature correlates with atmospheric pressure, not atmospheric composition. Venus’ atmosphere has 95% CO2, Earth’s atmosphere has 0.04% CO2. Incredible that an entire field of (junk) science could be based on such a fundamental misunderstanding of basic physics.
The surface of Venus receives very little sunlight, and receives no sunlight for months at a time. yet the temperature never drops. How could anyone be stupid enough to believe the high temperatures are due to the “greenhouse effect?”
