Yesterday's Journal published six letters to the editor under the headline "Unchecked Climate Change Will Lead to War". Of the six letter writers, none discussed the science of global warming, things like is it happening, how fast is it happening, what causes it. One asserted that CO2 is poisonous, it isn't. One talked about examining data over the past 21 centuries. The thermometer wasn't invented until just 4 centuries back. Lacking thermometers, ancient writer's ideas of hot and cold are pretty subjective. Tree ring width indicates amount of rainfall, not temperature. We have a few records of time of planting and harvest but that's about it. That ain't 21 centuries of data in my book. One writer thinks Zika, malaria, and dengue are caused by climate change. That's false. Diseases are caused by germs or viruses (virii?). One writer is an anti-fracker, and blames global warming and a whole bunch of stuff on fracking.
Dunno about that Journal. They used to be better than this.
