Rich Lowry’s June 3 opinion piece, “Obama’s phantom foe: Climate change,” deserves a thoughtful response. The best response is the Department of Defense 2014 Climate Adaptation Roadmap, from which I quote:

“Rising global temperatures, changing precipitation patterns, climbing sea levels, and more extreme weather events will intensify challenges of global insecurity, hunger, poverty, and conflict. They will likely lead to food and water shortages, pandemic disease, disputes over refugees and resources, and destruction by natural disasters in regions across the globe. In our defense strategy, we refer to climate change as a ‘threat multiplier’ because it has the potential to exacerbate many of the challenges we are dealing with today — from infectious disease to terrorism. We are already beginning to see some of these impacts.”

From Bosnia and Rwanda to ISIS, we see horrors to which one of the responses inevitably is: Send in U.S. troops. In each case, honest people disagree as to the practicality and efficacy of boots on the ground. However, Mr. Lowry writes that caution is a sign of weakness and seeks to politicize these wrenching decisions that could cost lives and draw us into endless conflict.

The most hawkish Republican candidate for the presidential nomination is Sen. Lindsey Graham. At least he is forthright in his position and speaks with knowledge and authority.

Politico.com reported on June 7 from Sen. Graham’s campaign that he is urging action on climate change and states that if he is president, he will address climate change in a business-friendly way. This way is a revenue neutral carbon tax and dividend. Learn more about it.
