Secretary of State John Kerry doubled down again on his stance that climate change is one the biggest – if not the biggest – national security threat facing the U.S. “We see people fighting over water in some places,” Kerry said. “There are huge challenges to food security and challenges to the ecosystem, our fisheries and … the acidification of the ocean is a challenge for all of us. And when you accrue all of this, while we are confronting ISIL and we are confronting terrorism and we are confronting Ebola and other things, those are immediate. [Climate change] also has an immediacy that people need to come to understand, but it has even greater longer-term consequences that can cost hundreds of billions, trillions of dollars, lives, and the security of the world.” Two observations: The Left talks about fighting climate (or poverty, or inequality, or whatever other social issue du jour) with greater urgency than any real national security issue. Second, climate change is guaranteed to cost trillions of dollars worldwide if we follow the Left’s prescription of government controls.
