In case you have lingering doubts about the reality of human-caused global warming, hop on an airplane to parts of India or Pakistan and spend a few days. And, as long as you’re there, maybe be a good citizen and pick up a few of the dehydrated birds that drop out of the sky. Then, use the syringe you brought along to feed it some water before it dies in your hands. And, maybe do the same for some of the people sprawled out on the roadside before they die right before your eyes. After all, people are already dying from the humid heat. Maybe you could help them survive and while at it maybe bring along that friend who’s a climate denier for help saving some lives. It’s good for his or her soul to open their eyes to reality.
