This posting combines the March global temperature anomaly and the Solar Cycle 24 stats. Below are the UAH satellite global temperature anomalies from Dr Roy Spencer’s website. The stats below the graph show the summary since 2016 through March 2017 for the regions.

The anomaly drop of 0.16C was a substantial change. This has been happening without a La Nina following the El Nino.
Solar Cycle 24’s to-date April International Sunspot number is 26.6 versus March’s number of 17.7. So, this month is a little more active but still things are quiet. Cycle 24 began in January 2008. The mean Cycle length is 11.1 years so it should be over around January of 2019.
As noted in previous postings the solar polar field strength following a maximum is currently a popular way to predict the following Cycle strength. The Black line in the chart below is the line to watch. That line is the combined North and South solar polar field strength. So far it is slightly smaller than the size of Solar Cycle 23—thus using this theory, it Cycle 25 should be about the same size as 24 or maybe just a bit smaller. Amended for clarity on 4/20 cbdakota
