If you pay attention to news about climate change you're undoubtedly aware that the warnings about the potential catastrophes facing human civilization are increasingly dire. I pay close attention to the subject and its clear to me that the warnings are coming in greater volume and getting ever-more threatening.

I'm crawling toward my mid-70s so I'm probably too old for the worst of the predictions to manifest fully during my lifetime. But I can't help but think that my children and certainly my grandchildren will experience climate events that could upend human life as we know it.

Just last week, for example, saw coverage that the massive ice sheets covering Antarctica appear to be collapsing faster than previously thought. That means a steeper rise in sea levels, which is terrible news for coastal populations worldwide. Click here to read how The New York Times covered the story.

Of course I'm aware that not everyone agrees about the reality of climate change or to what degree, if any, it's human-caused. But this post is not about arguing the issue's merits.

Like the preponderance of scientists who study the issue, I believe that climate change is a real threat and that the increased levels of atmospheric heat-trapping gases result directly from humanity's continued reliance on fossil fuels, in particular coal and petroleum.
