As an environmental advocate I have placed land under conservation and restored habitats. I recycle, reuse rainwater, walk when others drive, and generally leave a small environmental footprint.
Yet I am angered by climatologists, environmentalists, and politicians who purvey one of the biggest myths of modern time: that climate change (aka global warming) during the past half century is primarily due to anthropogenic (manmade) causes.
I know this statement will likely have readers scurrying to fire off rebuttals. Many may point to the Intergovernmental Panel on Climate Change (IPCC) report that says a 90-percent chance exists that the observed temperature increases of the last 50 years are the result of greenhouse gas emissions. The report goes further to say that human activities have begun affecting specific aspects of the climate, such as heat waves, wind patterns, and continental temperatures.
