I remember my great-grandfather, a retired ironworker from local 40, telling me it all started happening about 120 years ago, back in the summer of 2013, when he was in his early 20s. He said the world leaders had been discussing global warming for a number of years, maybe as early as the 1970s.
Although there were some strides over the decades to protect the fragile ozone layer, the efforts were too little too late. That summer, there was a severe heat wave, with 100-degree days on the East Coast for nearly a week.
