Sun Activity Expected To Drop Significantly

One of the crucial aspects of climate change that is seldom mentioned by global warming partisans is the effect of the sun on climate.  To a layman like myself, that would seem to be a big oversight.  Watts Up With That is reporting that the American Astronomical Society is predicting a big drop in solar activity beginning in a few years. 

A missing jet stream, fading spots, and slower activity near the poles say that our Sun is heading for a rest period even as it is acting up for the first time in years, according to scientists at the National Solar Observatory (NSO) and the Air Force Research Laboratory (AFRL).
As the current sunspot cycle, Cycle 24, begins to ramp up toward maximum, independent studies of the solar interior, visible surface, and the corona indicate that the next 11-year solar sunspot cycle, Cycle 25, will be greatly reduced or may not happen at all.

The results were announced at the annual meeting of the Solar Physics Division of the American Astronomical Society, which is being held this week at New Mexico State University in Las Cruces:

All three of these lines of research to point to the familiar sunspot cycle shutting down for a while.
“If we are right,” Hill concluded, “this could be the last solar maximum we’ll see for a few decades. That would affect everything from space exploration to Earth’s climate.”
