The current solar wind and sunspot activity are very low compared to recent past observations. The net result is that the sun has not emitting as much radiation to the planet. This change hasn't been enough to counter other warming effects here on Earth, but the cycle of sun activity does lead me to wonder about the larger system of factors which are currently operating.
Longer term cooling trend?
Short term cooling trend?
What happens if the sun increases radiation output given the amount of greenhouses in our atmosphere now?
