Solar activity has shown a major spike in the twentieth century, corresponding to global warming. This cyclic variation was acknowledged by a recent NASA study, which reviewed a great deal of past climate data. (Source: Wikimedia Commons)
Report indicates solar cycle has been impacting Earth since the Industrial Revolution
Some researchers believe that the solar cycle
influences global climate changes. They attribute recent warming trends to cyclic variation. Skeptics, though, argue that there's little hard evidence of a solar hand in recent climate changes.
Now, a new research report
from a surprising source may help to lay this skepticism to rest. A study from NASA’s Goddard Space Flight Center in Greenbelt, Maryland looking at climate data over the past century has concluded that solar variation has made a significant impact on the Earth's climate. The report concludes that evidence for climate changes based on solar radiation can be traced back as far as the Industrial Revolution.
