Cosmic rays, solar activity have greater impact on climate models


At the Pierre Auger Observatory in Argentina, cosmic rays have been detected from far off galaxies. Picture: Pierre Auger Observatory.
The impact of changes in solar activity on Earth’s climate was up to seven times greater than climate models suggested according to new research published today in Nature Communications.
Researchers have claimed a breakthrough in understanding how cosmic rays from supernovas react with the sun to form clouds, which impact the climate on Earth.
The findings have been described as the “missing link” to help resolve a decades long controversy that has big implications for climate science.

Lead author, Henrik Svensmark, from The Technical University of Denmark has long held that climate models had greatly underestimated the impact of solar activity.
He says the new research identified the feedback mechanism through which the sun’s impact on climate was varied.
Professor Svensmark’s theories on solar impact have caused a great deal of controversy within the climate science community and the latest findings are sure to provoke new outrage.

He does not dispute that increased levels of carbon dioxide in the atmosphere have a warming impact on the climate.
But his findings present a challenge to estimates of how sensitive the climate is to changes in carbon dioxide levels in the atmosphere.

Professor Svensmark says his latest findings were consistent both with the strong rise in the rate of global temperature change late last century and a slowdown in the rate of increase over the past 20 years.
‘’It gives a physical foundation to the large body of empirical evidence showing that solar activity is reflected in variations in Earth’s climate,” a media statement accompanying the scientific report said.
“For example, the Medieval Warm Period around year 1000AD and the cold period in the Little Ice Age 1300-1900 AD both fits changes in solar activity,” it said.
“Finally we have the last piece of the puzzle of why the particles from space are important for climate on Earth,” it said.
