Global Warming is Mostly Caused By the Sun, Not Humans, Says Astrophysics Professor

 “There’s no such thing as a scientific consensus,” Nir Shaviv, a Professor at the Racah Institute of Physics at the Hebrew University of Jerusalem says in response to a question about what he thinks of the widespread claim that there is a scientific consensus on the anthropogenic nature of climate change. “In science, we deal with open questions and I think that the question of climate change is an open question. There are a lot of things which many scientists are still arguing about,” he explains.

Indeed, there are scientists who say that climate change is caused entirely by humans and the situation is very dire. But then there are those who say that although humans are causing much of the warming, the situation is not as bad as we are being told by politicians and activists through the media. Some think that CO₂ plays an important part in the current warming trend and some believe its role is insignificant.

Although Shaviv assesses that some of the warming in the 20th century is indeed the result of increasing atmospheric CO₂ concentrations, most of the change is a natural phenomenon. “My research has led me to strongly believe that based on all the evidence that’s accumulated over the past around 25 years, a large part of the warming is actually not because of humans, but because of the solar effect,” he says....<<<Read More>>>...
