Strategic Climate Blunder

Summarizing the theme of a recent hearing at the Senate Foreign Relations Committee, Kate Sheppard at Grist writes:

More senators and citizens might support a climate bill if it emphasized the national security challenges presented by climate change, former Virginia Sen. John Warner (R) argued on Tuesday.

I’ve made similar points here and here.

I’ll say it again: I’m astonished that enviros and climate advocates haven’t made this central to their argument. The other side surely understands the powerful symbolism of military brass and national security hawks warning of climate change. Why do you think Marc Morano at Climate Depot offers no linkage to news of the hearings or statements from Warner and the other witnesses?
