NASA: We May Be On the Verge of a “Mini-Maunder” Event

Is a Planetary Cooling Spell Straight Ahead?
All climate scientists agree that the sun affects Earth’s climate to some extent. They only disagree about whether or not the effect form the sun is minor compared to man-made causes.
We noted in 2011:
This week, scientists from the US Solar Observatory and the US Air Force Research Laboratory have discovered – to their great surprise – that the sun’s activity is declining, and that we might experience the lowest solar output we’ve seen since 1645-1715. The Register describes it in dramatic tones:
What may be the science story of the century is breaking this evening.
Scientists who are convinced that global warming is a serious threat to our planet say that such a reduced solar output would simply buy us more time … delaying the warming trend, but not stopping or reversing it.
On the other hand, scientists who are skeptical about global warming say that the threat is a new mini ice age. (Remember that scientists have been convinced in the past that we would have a new ice age, and even considered pouring soot over the arctic in the 1970s to help melt the ice – in order to prevent another ice age. Obama’s top science advisor was one of those warning of a new ice age in the 1970s. And see this.)
