We may be entering the largest solar cycle ever recorded. While the sun is not responsible for global warming?human emissions are behind that?sunspots CAN make things worse?just when we thought we might be getting a reprieve.
In BBC News, Dr. David Whitehouse reports on a drilling of ice cores in Greenland that reveals that the sun is more active now than it has been at anytime in the last 1,000 years. While we can now view sunspots with satellite technology, humans have been looking at them through telescopes for almost 400 years. Between 1645 and 1715, sunspot activity was greatly reduced and this brought on what has come to be known as the “little ice age” in Europe.
In New Scientist, Stuart Clark reports that the sun’s brightness rises and falls around every 100,000 years and this is exactly the same time period between ice ages on earth.
