Solar scientists predict that, by 2020, the sun will be starting into its weakest solar cycle of the past two centuries. They say this will likely lead to unusually cool conditions on Earth. It is also predicted that this cool period will go much longer than the normal 11 year cycle, as the Little Ice Age did. The climate threat is actually cooling, especially to countries like Canada. On the northern limit to agriculture in the world, very little cooling would likely destroy much of its food crops.
The Little Ice Age—the coldest period in the past 1500 years—corresponded perfectly with the Maunder Minimum. There was virtually no sunspot activity for almost seven decades in the Maunder Minimum(per Willie Soon/ Harvard/Astrophysics). It turns out that for those 60-70 years the northern half of our globe was in a deep freeze. The New York harbor froze, allowing walkers to journey from Manhattan to Staten Island, and the Vikings abandoned Greenland–a once verdant land that became tundra. In that Little Ice Age, Finland lost 1/3 of its population and Iceland 1/2.
Which one should we believe? The warming or the cooling?
