An important name to remember is Valentina Zharkova, a professor at Northumbria University (Newcastle) who has developed the most accurate model so far anticipating temperature fluctuations.

... double dynamo waves generated in inner and outer layers of the Sun indicate that the solar activity is heading in the next three decades (2019-2055) to a Modern grand minimum similar to Maunder one.

A Modern Grand Minimum similar to the Maunder one refers to a lessening of solar activity which will result in conditions similar to the Little Ice Age. During that time 50 percent of Europe died due to the cold. Unlike other predictions that are looking at 12 years from now, this one should be starting at the end of this year.

This map illustrates that a number of areas were average or below average as well as some were the warmest on record. Imagine what would happen if those areas that are a little warmer than average became cooler than average. Sizable areas in the crop-producing areas of North America, Europe and China will no longer be able to produce food.

This is where sustainability does come into play. Whether there is confusion because the weather is too hot or because the weather is too cold is irrelevant. I am gratified that people are taking steps to re-green the deserts but the first step is the one that you take yourself ... not the step the other person takes.
