Cloud cover reduction?

Source: Earth is less bright than it used to be because there are fewer clouds in the air, study

The Earth is bouncing back less light into space because its cloud coverage isn't what it used to be, a study found. This is due to the cloud coverage being reduced due to a fluctuation in ocean temperatures, the researchers said.

Philip Goode, a researcher at New Jersey Institute of Technology, and a lead author on the study, described his findings to CNN.

Called 'albedo', this is the degree the earth reflects versus absorbs solar light. A complex function because more than visible light is involved. But in the past, there has been discussion of sea and surface ice loss increasing the absorption of solar heating. Yet some claimed as the earth warmed, more clouds would somewhat compensate. So take this lay report of a study with a grain of salt.

The scientific method means no one study is definitive but the body of work, replication by other means leads to trustable results. Certainly a loss of cloud cover is going to affect solar heating along with the greenhouse gasses. More details to follow over time. Please use peer reviewed sources.

In this model, the longer path through the greenhouse/CO{2} column means more solar energy is trapped. Higher clouds would reduce the longer path. Unfortunately, Dr Roy Spencer who I am skeptical of, claims clouds have a significant negative feedback effect ... cooling the earth. My fear is high clouds may sublimate into water vapor, another greenhouse gas, and trap more heat.

Although the cloud feedback is one of the largest remaining uncertainties in climatescience, evidence is building that the net cloud feedback is likely positive, and unlikely to be strongly negative.

"Climate models used by the International Panel on Climate Change (IPCC) assume that clouds provide a large positive feedback, greatly amplifying the small warming effect of increasing CO2 content in air. Clouds have made fools of climate modelers. A detailed analysis of cloud behavior from satellite data by Dr. Roy Spencer of the University of Alabama in Huntsville shows that clouds actually provide a strong negative feedback, the opposite of that assumed by the climate modelers. The modelers confused cause and effect, thereby getting the feedback in the wrong direction."​

As the earth warms, what is the effect of actual clouds on the earth energy balance? The experiment continues.
