The Sun’s Cycle Affects the Earth’s Climate?

It appears that an 11-year solar cycle  could affect the Earth’s weather patterns – so says a Space.com article posted on Live Science last week – Sun’s Cycle Alters Earth’s Climate.

“The sun is the ultimate source of all the energy on Earth; its rays heat the planet and drive the churning motions of its atmosphere.”

What about my carbon footprint? 

“The study could help scientists get an edge on eventually predicting the intensity of certain climate phenomena, such as the Indian monsoon and tropical Pacific rainfall, years in advance.”

This is a very interesting article and it never once mentions Global Warming or man-made climate change.

“An international team of scientists led by the National Center for Atmospheric Research (NCAR) used more than a century of weather observations and three powerful computer models to tackle this question.

“The answer, the new study finds, has to do with the Sun’s impact on two seemingly unrelated regions: water in the tropical Pacific Ocean and air in the stratosphere, the layer of the atmosphere that runs from around 6 miles (10 km) above Earth’s surface to about 31 miles (50 km).

“The study found that chemicals in the stratosphere and sea surface temperatures in the Pacific Ocean respond during solar maximum in a way that amplifies the sun’s influence on some aspects of air movement. This can intensify winds and rainfall, change sea surface temperatures and cloud cover over certain tropical and subtropical regions, and ultimately influence global weather.”
