Modern Solar Minimum (2000 - ?)
Modern Climatic Optimum (1890 - 2000) the world is getting warmer.
Concentrations of greenhouse gas increase. Solar activity increases.
Dalton Solar Minimum (1790 - 1820) global temperatures are lower than
average.
Maunder Solar Minimum (1645 - 1715) coincident with the 'Little Ice
Age'.
Sprer Solar Minimum (1420 - 1530) discovered by the analysis of
radioactive carbon in tree rings that correlate with solar activity
colder weather. Greenland settlements abandoned.
Wolf Solar Minimum (1280 - 1340) climate deterioration begins. Life gets
harder in Greenland.
Medieval Solar Maximum (1075 - 1240) coincides with Medieval Warm
Period. Vikings from Norway and Iceland found settlements in Greenland
and North America.
Oort Solar Minimum (1010 -1050) temperature on Earth is colder than
average.
There seem to have been 18 sunspot minima periods in the last 8,000
years; studies indicate that the Sun currently spends up to a quarter of
its time in these minima.

"There is no compelling evidence that carbon dioxide has any significant
control over the direction of global temperature and climate. The
processes that regulate the interannual to decadal fluctuations of
climate are poorly understood and, as yet, unpredictable" William
Kininmonth, Meteorologist, Former Head, National Climate Centre, Bureau
of Meteorology, 1986-1998
