As a rule of thumb, solar output is at its optimum for only 5 hours each day.

Spock would perish and the solar output might be affected.

Can the observed changes be explained by natural variability, including changes in solar output?

Since the advent of space-borne measurements in the late 1970s, solar output has indeed been shown to vary.

Variations in solar output can also bring about climate change on the Earth.

In the then current environmental conditions, this solar output would have been insufficient to maintain a liquid ocean.

It is simply that, light, with the balance and intensity of the local solar output at ground level on this planet.

They prefer to attribute warming to natural variations in solar output.

If our solar output grew to a significant proportion of our energy production, storage systems would become necessary.

The shell is thin, and the slight decrease in the solar output is not expected to last long.
