Vegetarian Week Analysis: How Our Food Choices Can Help Avert a Climate Catastrophe

by Richard Schwartz for Jewcology

There is good news and bad news. Unfortunately, the bad news is extremely bad, perhaps the most inconvenient truth one can imagine: the world is rapidly heading toward a climate catastrophe. This is the view of science academies worldwide and of over 97% of climate scientists.

Global temperatures have been rising. The 12 warmest years since temperature records have been kept in 1880 have occurred since 1998. Every decade since the 1970s has been warmer than the previous decade. Glaciers and polar ice sheets are melting far faster than the projections of climate scientists. There has been a major recent increase in the number and severity of severe climate events, including heat waves, droughts, wildfires, storms, and floods.

Many climate experts, including James Hansen, former director of the National Aeronautics and Space Administration (NASA) Goddard Institute for Space Studies, believe that a safe upper limit for carbon dioxide in the atmosphere is 350 parts per million (ppm). Atmospheric CO2 recently reached 400 ppm and it has been growing by 2-3 ppm per year, making climate experts very concerned.

What has Hansen and other climate scientists especially worried is that climate change could soon reach a tipping point, unleashing a vicious cycle of rapid climate change leading to disastrous consequences -- melted sea caps, flooded cities, mass species extinctions and spreading deserts, among other events -- unless major changes in how humanity uses energy soon occur.

There is a very strong scientific consensus that climate change is happening, that it poses a major threat to humanity and that human activities are the primary cause, as indicated by many peer-reviewed articles in respected science journals and statements by science academies all over the world. These views were reinforced by a report released on September 27, 2013 by the Intergovernmental Panel on Climate Change, a group composed of thousands of climate experts from many countries, that indicated, among other things that they were at least 95% certain that climate change is largely caused by human activities and that the oceans may rise by 3 feet by the end of this century. The conservative group ConservAmerica (www.ConservAmerica.org), formerly known as "Republicans for Environmental Protection," is working to reduce denial among conservatives.

The good news is that shifts toward vegan diets can make a major difference. It may seem naïve to argue that a mere change of diet could be a potent prescription for combating climate change, but the evidence is incontrovertible, and slowly the public is getting the message.
