Variations of cloud cover can easily overwhelm greenhouse warming claimed to be caused by changes of atmospheric CO2. This has been acknowledged by scientists for decades. Scientists also have a limited capacity to measure cloud effects. The result is massive uncertainties about the effects of clouds on climate change.
Cloud microphysics are the processes affecting precipitation and evaporation. They are an important part of Earth’s weather and climate.
There is no method to measure needed in-cloud temperatures to less than 0.1°C because conventional airborne temperature sensors are typically 0.5°C.
There is no real understanding of the energy transfers that go on inside clouds. NASA has admitted that climate models lack the precision required to make climate projections due to the inability to accurately model clouds.
Science requires accurate data to refute or “corroborate” hypotheses such as the questionable claim that CO2 levels control the climate.. The precise effects of changing cloud cover remains a mystery. Cloud science is so far from being settled that climate alarmists just ignore it.
