Sunspots 2015: Year of the decline
Solar sunspot maximum was reached in April of 2014. That did not become known until recently because solar max is computed as a 13-month running average. You can’t know it has been reached until at least seven months after the fact. There have been two months of decline since then, so it is reasonably certain the maximum was finally reached. As it is, it was over two years later than originally predicted.
If the current cycle follows past solar behavior then 2015 will see a steep decline in solar activity as it progresses toward solar minimum in the next five years or so.
The current cycle (Cycle 24) has strong similarities to both the Dalton Minimum and Cycle 12 that peaked in 1883. Both time periods are associated with cold earth temperatures. Cycle 12 is more meaningful because it is supported by current United Nations IPCC data.
That being the case, it’s time to start thinking about breaking out the cold weather gear.
