Responding to Sen. Kerry's statement, Clinton also said: "At the extreme, it threatens our very existence but well before that point it could well incite new wars of an old kind over basic resources like food, water and arable land." (Hat tip: Gristmill)
It is I didn't watch much of the hearing, but I did catch some of it this afternoon. It is good to see that policy-makers are beginning to move beyond climate change as an environmentalist-only issue.
Interestingly, it doesn't appear that any of the Senators asked Clinton about Climate Change, either in regards to the ongoing UN negotiations or its national security impacts. What that says to me is that the long-term threat of climate change will never be the number one priority for Senators when near-term shooting wars are filling the front pages.
