"Affects climate change."
GW is the change in temperature, CC is the result of that warming.

"The Solar Cycle 23 began during April 1996 and had its peak in early 2000/2001. The decline phase thereafter extended from 2002 until December 2009. That was the longest decline phase of any of the previous 23 solar cycles."


'98 was the hottest year ever, then '05, then '10.




"Current Solar Cycle 24 has been declining much faster than expected. There is some concern that Solar Cycle 24 might possibly extend as well for the weather has been getting excessively colder in the northern regions. The peak in the cycle arrived during April 2014 reaching an average sunspot number of 82."


Then, '14 became the warmest year, then '15, and then '16.

The above graph compares global surface temperature changes (red line) and the Sun's energy received by the Earth (yellow line) in watts (units of energy) per square meter since 1880. The lighter/thinner lines show the yearly levels while the heavier/thicker lines show the 11-year average trends. Eleven-year averages are used to reduce the year-to-year natural noise in the data, making the underlying trends more obvious.

The amount of solar energy received by the Earth has followed the Sun’s natural 11-year cycle of small ups and downs with no net increase since the 1950s. Over the same period, global temperature has risen markedly. It is therefore extremely unlikely that the Sun has caused the observed global temperature warming trend over the past half-century.
