global warming to increase terrorism- really? we didn't know this?

"Global warming could destabilize "struggling and poor" countries around the world, prompting mass migrations and creating breeding grounds for terrorists, the chairman of the National Intelligence Council told Congress on Wednesday.
Climate change "will aggravate existing problems such as poverty, social tensions, environmental degradation, ineffectual leadership and weak political institutions," Thomas Fingar said. "All of this threatens the domestic stability of a number of African, Asian, Central American and Central Asian countries."
People are likely to flee destabilized countries, and some may turn to terrorism, he said.
"The conditions exacerbated by the effects of climate change could increase the pool of potential recruits into terrorist activity," he said.
"Economic refugees will perceive additional reasons to flee their homes because of harsher climates," Fingar predicted. That will put pressure on countries receiving refugees, many of which "will have neither the resources nor interest to host these climate migrants," he said in testimony to the House Select Committee on Energy Independence and Global Warming."
