Faulty Hypothesis? NASA ERB Measurements Don’t Show Significant Radiative Budget Differences

NASA earth radiation budget measurement from satellite data don’t support global warming claims.
Analyst blogger Zoe Phin downloaded and analyzed 10 gigabytes of NASA instrumental data on the earth’s radiation budget (ERB) fully covering the years 2003 to 2019 [site] [data].
High clouds should be warming the planet, and low clouds cooling it, NASA says. Yet 16 years of their own satellite measurements don’t support the claim. Image: NASA.
The idea is to see the effect of clouds at the surface, especially the so-called Upwelling Longwave Radiation (LW_UP).
High clouds supposedly warm the planet
But first, NASA tells us high clouds are much colder than low clouds and the surface and so they radiate less energy to space than low clouds do. And because high clouds absorb energy so efficiently, they have the potential to raise global temperatures. In a world with high clouds, much of the energy gets captured in the atmosphere. High clouds make the world a warmer place. If more high clouds were to form, more heat energy radiating from the surface and lower atmosphere toward space would be trapped in the atmosphere, and Earth’s average surface temperature would climb.
Low clouds said to cool the planet
NASA also adds that low stratocumulus clouds – on the other hand – act to cool the Earth system because they are much thicker and not as transparent. This means they do not let as much solar energy reach the Earth’s surface. Instead, they reflect much of the solar energy back to space (their cloud albedo forcing is large).
NASA adds that stratocumulus clouds radiate at nearly the same intensity as the surface and do not greatly affect the infrared radiation emitted to space (their cloud greenhouse forcing on a planetary scale is small). The net effect of these clouds is to cool the surface.
