Cold Sweeps the Southern Hemisphere Major Crop Damage

It would seem as if the southern hemisphere might be giving the northern hemisphere a glimpse at what the Grand Solar Minimum is bringing. The Sun's activity affects the Earth far more than man does. During the Maunder minimum, we had a temperature drop around the globe. The "recorded" temperatures that we get now, didn't start until 1860, after the Little Ice Age. The Little Ice Age occurred after the Medieval Warm Period. I'm sure all the global warmest back in that time were shouting "Ye, shall stopith the expulsion of carbon or God shall smite us all!"

Grand solar minima occur when several solar cycles exhibit lesser than average activity for decades or centuries. Solar cycles still occur during these grand solar minimum periods but are at a lower intensity than usual. Grand solar minima have shown some correlation with global and regional climate changes.
The Maunder minimum in a 400-year history of sunspot numbers. The Maunder Minimum, also known as the "prolonged sunspot minimum", is the name used for the period starting in about 1645 and continuing to about 1715 when sunspots became exceedingly rare, as noted by solar observers of the time.
