The Sun will play it cool between now and 2022, or maybe longer



National Solar Observatory and Air Force Research Laboratory : scientists
Recent measurements indicate an unexpected drop in solar activity, which will manifest itself as few or no sunspots, and reduced radiation reaching earth.
So far in earth’s history, periods of reduced solar activity have almost always instigated prolonged cooling of earth’s climate. Some even brought on ice ages. This cooling could be a good thing if it is steep enough to offset some of earth’s global warming. Of course, if it is too strong, then it could introduce a whole new set of problems. At the very least, it will require space satellites and telecommunications systems to reconfigure many of their settings, since they are impacted by solar output. BUT… The observation measurements could be wrong, and the cooling might not happen at all. Or it could happen but have minimal effects on earth’s climate.
