I hope you are not contemptuous of planning by the Pentagon for worst case scenarios. I sure as hell hope they're doing such planning for the terrorist threat. "The climate could change radically, and fast. That would be the mother of all national security issues... ...for planning purposes, it makes sense to focus on a midrange case of abrupt change." (The midrange case of abrupt change is the focus of the Pentagon study.) Here are some quotes from page one. (You posted a link to page two): "Like the terrorists, though, the seemingly remote climate risk may hit home sooner and harder than we ever imagined. In fact, the prospect has become so real that the Pentagon's strategic planners are grappling with it. "The threat that has riveted their attention is this: ...Growing evidence suggests the ocean-atmosphere system that controls the world's climate can lurch from one state to another in less than a decade—like a canoe that's gradually tilted until suddenly it flips over. Scientists don't know how close the system is to a critical threshold. But abrupt climate change may well occur in the not-too-distant future. If it does, the need to rapidly adapt may overwhelm many societies—thereby upsetting the geopolitical balance of power...." (IMO, a plausible danger as dire as the one described in the Pentagon report (the mid-range version was examined) shouldn't be handled the way flight schools were before 9/11. As the Report suggests, "it is time to recognize it as a national security concern." ) From page three: "Over the past decade, data have accumulated suggesting that the plausibility of abrupt climate change is higher than most of the scientific community, and perhaps all of the political community, are prepared to accept. In light of such findings, we should be asking when abrupt change will happen, what the impacts will be, and how we can prepare—not whether it will really happen. In fact, the climate record suggests that abrupt change is inevitable at some point, regardless of human activity. Among other things, we should: • Speed research on the forces that can trigger abrupt climate change, how it unfolds, and how we'll know it's occurring. • Sponsor studies on the scenarios that might play out, including ecological, social, economic, and political fallout on key food-producing regions. • Identify "no regrets" strategies to ensure reliable access to food and water and to ensure our national security. • Form teams to prepare responses to possible massive migration, and food and water shortages. • Explore ways to offset abrupt cooling—today it appears easier to warm than to cool the climate via human activities, so there may be "geo-engineering" options available to prevent a catastrophic temperature drop. In sum, the risk of abrupt climate change remains uncertain, and it is quite possibly small. But given its dire consequences, it should be elevated beyond a scientific debate. Action now matters, because we may be able to reduce its likelihood of happening, and we can certainly be better prepared if it does. It is time to recognize it as a national security concern. "
