After I wrote a commentary here on June 3, 2012 about global warming and climate change and what all this might mean for the future existence of Israel as a state in the arid Middle East, an Israeli scientist that I contacted told me that he thought I was barking up the wrong tree and was wrong about global warming.
This led to what, for me, was a fascinating e-dialogue.
I met Professor Emeritus Giora Shaviv, the Swartzmann-Medvedi chair in Space Sciences at The Technion in Haifa after coming across a 2009 news article in the Jewish Chronicle in London headlined “Israeli scientist denies global warming.”
Although Dr Shaviv and I don’t see eye to eye on this, I wanted to find out more about his ideas and climate views, after reading this opening lines of the London story: “A leading Israeli scientist has renounced the concept of man-made global warming at a lecture given to the British Technion Society, just days before world leaders meet to discuss ways to halt it. Professor Giora Shaviv professor of physics at the Technion, claimed that the accepted level of carbon dioxide in the air is wildly exaggerated.”
”Dr Shaviv said that though for years the Intergovernmental Panel on Climate Change (IPCC) has claimed that an increase in carbon dioxide has led to an increase in temperature, in fact, the reverse is correct. He argued that the movement of the sun affects temperature, which influences the levels of carbon dioxide, and that these levels have risen and fallen for centuries, even before mankind.”
Then came the clinker: “CO2 is not responsible for heating the earth, the cause is the activity of the sun which we cannot control,” Dr Shaviv said.
