English: Sunspot numbers rise and fall over an 11-year cycle, and these sunspots can be observed on the surface of the sun as dark discs. The current Solar Cycle 24 began in January 2008. This is the third 11-year cycle in a row since the peak of Cycle 21 in the late 1980s with diminishing peak sunspot numbers. These diminishing peaks and troughs of solar activity highlight the influence of longer-term solar cycles that impact the magnitude of the 11-year solar cycle (sunspot numbers) and indicate that the sun is moving into a grand solar minimum phase. These longer-term cycles include the Gleissberg (50–80 and 90–140 year periods) and Suess cycles (170–260 year periods). At this stage of the glacial cycle, the sun spends about twice the time in grand solar minima compared with grand solar maxima.

Despite what we are told by the Intergovernmental Panel on Climate Change (IPCC), the sun is the main controller of earth's climate on glacial cycle-, millennial-, centennial-, decadal-, and annual- time scales. You can see the significant correlations above between solar activity and the Northern Hemisphere climate. By erroneously dismissing or omitting the role of the sun in natural climate change (electromagnetism and magnetism), the IPCC has made a grave error in its key climate risk assessment and advice provided to governments.
