Solar panels on planet Mercury would yield more than 6 times the energy than on Earth. No surprise here, Mercury is a lot closer to our central star. And one would also feel the variations the Sun throws at us a lot more. Distance matters. But so do the pulsations of Sol. The gravitational mass at the center of our Solar System is alive – not in a biological sense but it’s a pulsating, highly evolving system. And as it gives us more or less light, we will be more or less comfortable. What are the chances we can regulate the Sun’s activity?
The impact of solar variations on the climate is uncertain and subject to substantial debate. However, you would not infer from the IPCC assessment reports that there is debate or substantial uncertainty surrounding this issue.
