Solar Energy Systems

Mae Said:

Does NASA track and keep records of the amount of solar energy radiating?

We Answered:

I don't think NASA does specifically, but there are a number of organizations which do.

Satellites have been monitoring solar activity since 1979. Over the past 31 years, solar activity has remained completely flat on average. Here's the data:

Scientists have also put together data on solar activity from much further back using various proxies. For example, when there are more sunspots it also means there's more solar activity, and people have been monitoring sunspot number for centuries. Here's some longer-term data.

As you can see, the current global warming is clearly not being caused by the Sun, since solar activity has not increased in over 50 years. This is the conclusion of every scientific study on the subject.

We don't have enough information about the temperature changes on Mars to compare them to those on Earth. We don't even know for sure if Mars is warming, let alone how much. But we do know that the Sun isn't causing global warming on Earth right now.
