Solar activity minimum in 2030, next cold period

Here we have the former solar minimum, with start and end year (and possible time range with peak year) with a time cycle related to orbital influences by Jupiter and Saturn of around 180 years
1010-1050 Oort minimum
1100-1250, medieval maximum
1280-1340 (1310): around the time of great famine, Wolf minimum
1420-1570 (1430-1490-1550), Sporer minimum
1645-1715 (1610-1670-1730), little ice age, Maunder minimum
1790-1830 (1790-1850-1910), Dalton minimum
2010- 2090 (1970-2030-2090), next cold period
2110, start of next little ice age

Accordingly to several researchers solar activity may remain high during the beginning of 21st century but then decline, bringing a cold period around 2030. We are already seeing this. Solar activity may increase by end of the century but then in about 150-200 years we will be entering the next severe cold period, much like the little ice age. The ice age is due to start in this millennium.
