Who’s afraid of global warming?
By Esti Ahronovitz
From Haaretz.com, February 23, 2009
The blackboard in Prof. Nir Shaviv’s office in the Department of Physics at Hebrew University is covered with equations and graphs. He’s hunched over the computer, searching for another illustration, another study that will underscore the subject of our talk: the effect of cosmic rays on the earth’s warming.
Shaviv is the preeminent Israeli scholar among a handful throughout the world who believe that human beings are not responsible for global warming. The consequences of global warming were portrayed in Al Gore’s successful 2006 film, “An Inconvenient Truth,” which presents a frightening scenario to which one can hardly remain indifferent: giant ice caps melting, vast areas of human settlement covered by seas that overflow their banks, fierce hurricanes, new strains of bacteria, plagues and death.
The United Nations Intergovernmental Panel on Climate Change (IPCC) considered the most authoritative body on environmental issues, stated in its 2007 report that the earth’s temperature has risen by 0.74 degrees Celsius over the past century. The panel predicted that by the year 2100, the earth’s temperature could rise by another 2-4.5 degrees. Most of the world’s scientists share the belief that there is a correlation between the rise in temperature and the rise in the amount of carbon dioxide and other greenhouse gases derived from the burning of fossil fuels, from power stations that use petroleum or coal, from auto emissions, factory smokestacks and more.
Shaviv refuses to get worked up: “The hysteria surrounding the concept of ‘global warming’ will fade over the years,” he says. “People will see that the apocalyptic forecasts are not coming true. Today there is no fingerprint attesting that carbon dioxide emission causes a rise in temperature. A Grad missile that falls in Sderot should be more cause for concern.” Back to the Ice Age Last Wednesday, Shaviv was featured in a documentary broadcast on Channel 8, “The Cloud Mystery,” alongside Danish scientist Henrik Svensmark, a physicist whose pioneering experiments conducted in Copenhagen revealed how changes on the sun’s surface and cosmic rays are what affect climate, and not the polluting gases from manmade sources.
