Climate change – over the past few decades, it has become one of the major concerns for the scientists. They are constantly trying to find out the reasons for such rapid climate change. Climate skeptics used to blame the sunspots for the rapid increase in global temperatures rather than human activity on earth. On the contrary, scientists have recently reported that the activity on the sun will have little impact on the Earth’s climate. The study was carried out by the director of the World Data Centre named Frederic Clette, Leif Svalgaard from the Stanford University and Ed Cliver from the National Solar Observatory. The results were presented in Hawaai, at the International Astronomical Union.
Those who thought that the solar activity might have caused the global climate change used to say that since last three centuries, maximum solar activity has been recorded along with the rise in global temperatures as well. Furthermore they also reported that from 1885 to 1945, there was a marked increase in the number of sunspots, which is commonly known as the Modern Grand Maximum. Therefore, they were of the view that solar activity would be the main cause of the climate change.
Now the scientists reported that solar activity is just a patsy in the game. They proposed the idea that counting the sunspots is not the right method to determine the solar activity. It is pertinent to mention here that this method was named as Group Sunspot Number.
Recently a group of scientists came up with the improved method, which was named Sunspot Number Version 2.0. Through this method, they say that since 1700, there was no Modern Grand Maximum and that solar activity is fairly steady.
Furthermore, the new method also proposed the idea to re evaluate the existing models of climate evolution and made it more difficult to explain climate change, observed since the beginning of the 18th century.
