Nir Shaviv is an Israeli astrophysicist and chairman of Jerusalem’s Hebrew University’s physics department. He says that his research, and that of colleagues, suggests that rising CO2 levels play only a minor role in earth’s climate compared to the influence of the sun and cosmic radiation.
“Global warming clearly is a problem, though not in the catastrophic terms of Al Gore’s movies or environmental alarmists,” said Shaviv. “Climate change has existed forever and is unlikely to go away. But CO2 emissions don’t play the major role. Periodic solar activity does.”
But I thought that 97% of climate scientists agreed that human activity is the main driver of climate change?
“Only people who don’t understand science take the 97% statistic seriously,” said Shaviv. “Survey results depend on who you ask, who answers and how the questions are worded. In any case, science is not a democracy. Even if 100% of scientists believe something, one person with good evidence can still be right.”
