Changing sun, changing climate

"Scientists have been studying solar influences on the climate for more than 5000 years.Chinese imperial astronomers kept detailed sunspot records, and noticed that more sunspots meant warmer weather. In 1801, celebrated astronomer William Herschel, the first to observe Uranus, noted that when there were fewer spots the price of wheat soared. He surmised that less “light and heat” from the sun resulted in reduced harvests."
"The close relationships between the abrupt ups and downs of solar activity and similar changes in temperature that we have identified occur locally in coastal Greenland; regionally in the Arctic Pacific and north Atlantic; and hemispherically for the whole circum-Arctic region. This suggests strongly that changes in solar radiation drive temperature variations on at least a hemispheric scale.
Close correlations like these simply do not exist for temperature and changing atmospheric CO2 concentration. In particular, there is no coincidence between the measured steady rise in global atmospheric CO2 concentration and the often dramatic multi-decadal (and shorter) ups and downs of surface temperature that occur all around the world."
