New direct evidence demonstrate that changes in solar activity influence climate
The theory that climate change is chiefly caused by solar influences “is no longer tenable,” says US National Academy of Sciences president Ralph Cicerone. Carbon dioxide, he argues, is the key driver of recent climate change. I beg to differ.
The amount and distribution of solar energy that we receive varies as the Earth revolves around the Sun and also in response to changes in the Sun’s activity. Scientists have now been studying solar influences on climate for 5000 years.
Chinese imperial astronomers kept detailed sunspot records. They noticed that more sunspots meant warmer weather on Earth. In 1801, the celebrated astronomer William Herschel noticed that when there were few spots, the price of wheat soared – because, he surmised, less “light and heat” from the Sun resulted in reduced harvests.
