Environmental attorney and activist Robert F. Kennedy Jr. has described George W. Bush as the worst environmental president in U.S. history. During Bush's first term in office, his administration initiated more than 200 rollbacks of environmental laws. These moves serve to benefit big corporations, which are no longer inconvenienced by having to comply with strict pollution control standards. This kind of environmental irresponsibility is contributing to increased global warming which, if allowed to continue unchecked, could pose a serious threat to human life around the world.
Despite the ongoing assertions of some diehard naysayers, hard data are now confirming that climate change is dramatic, real, and driven by fossil fuel burning. Weather patterns are increasingly unstable, deep oceans are warming, glaciers are melting, drought and famine are proliferating, sea levels are rising, and the timing of the seasons themselves is altered.
Increased levels of atmospheric carbon dioxide have resulted in a one-degree Fahrenheit rise in temperature over the last century. That may not seem like much of a warming effect, but the process is speeding up in a big way, and could soon careen out of control if measures are not taken to reduce the emissions of greenhouse gases. The UN's Intergovernmental Panel on Climate Change (IPCC) projects that the average global temperature will rise from three to 10 degrees Fahrenheit later in this century. Other studies suggest an even greater warming effect much sooner. The consequences could be cataclysmic.
Even farther inland, the consequences are bleak, as global warming will have a considerable effect on food production worldwide. The IPCC has predicted that a half-degree temperature increase would cause a drop of 20 to 40 percent in rice yields in Southeast Asia, and would cut India's wheat yield by up to 20 percent. Looking forward, it gets even worse and hits closer to home. The UN's Environmental Program projects that later this century global warming will reduce several of the world's key food crops, such as corn grown in the Midwestern U.S., by some 30 percent. Adding to this threat to food security is the fact that world food consumption has, for the first time in recorded history, outpaced food production for four consecutive years, according to the Earth Policy Institute. In other words, folks, already there is not enough food to go around.
Flooding and erosion of islands and coasts presents a serious hardship in affected areas of the world, but the airborne diseases and malnutrition caused by global warming are matters of life and death. Summing up the situation, the British medical journal "The Lancet" called indifference to climate change "a form of bio-political terrorism."
