On September 21, I was present at a piece of history...the People's Climate March of 2014. It was a huge event, planned with precision, and broken down into six contingencies. The route covered two miles. My interviews began with people waiting for the bus, on their way to the west side of Manhattan.
More than 97 percent of climate scientists agree that global warming is happening now; that it is largely caused by human activities; and that it poses significant risks to our health and our well-being. Yet too many elected officials appear determined to either ignore or refute the facts when it comes to climate change.
Let's hope that the tide soon washes away not only skepticism, but also the skeptics who for one reason or another refuse to accept reality. When they occupy leadership positions in government and block responsible action, they are as much a threat to national security as the climate disruptions they ridicule.
To get Americans engaged, speak to them in a language they readily understand and can appreciate -- dollars and cents. Put another way, the monetary penalties sustained from failing to reduce greenhouse gases far exceed the costs of preemptively taking those measures to slow escalating temperature rise.
