The predominant threats identified for installations are \u201chazards more directly tied to temperature change\u201d such as excessive heat, drought, and wildfires.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Other climate-related threats will increase over time, though to a lesser extent, according to the report. The risks assessed include coastal and river flooding, increased energy demand, and land degradation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Importantly, \u201cthere is no&#8230;[scenario] under which installation exposure to climate hazards is projected to decrease,\u201d said the authors in the report\u2019s \u201ckey takeaways\u201d section.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">While the worst is yet to come, according to climate scientists and the authors of the report, Austin said Thursday that \u201cextreme weather caused by climate change\u201d is already posing a major threat to military bases and readiness.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cHurricane Michael inflicted billions of dollars of damage at Tyndall Air Force Base in Florida. Severe flooding of the Missouri River&#8230;damaged Offutt Air Force Base, costing hundreds of millions of dollars,\u201d said Austin. \u201cThe wildfires in California have threatened other military installations, forcing repeated evacuations.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cThe homeland is no longer a sanctuary,\u201d <a href=\"https:\/\/www.defense.gov\/Explore\/News\/Article\/Article\/2572665\/dod-working-to-mitigate-climate-change-effects-on-installations\/\">said Richard Kidd<\/a>, Deputy Assistant Secretary of Defense for Environment and Energy Resilience. \u201cGoing forward, we\u2019re going to have to embed climate change as a consideration in all that we do.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A DoD <a href=\"https:\/\/www.defense.gov\/Newsroom\/Releases\/Release\/Article\/2581027\/dod-announces-installation-climate-exposure-assessments-plan-through-the-defens\/\">press release<\/a> called the report \u201ca critical first step in addressing the potential physical harm, security impacts, and degradation in readiness resulting from global climate change.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The report recommends that DoD develop a \u201cmultiple lines of defense\u201d approach to countering climate risks \u201cthat can include a mix of management, temporary, structural, nature-based, and nonstructural measures.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The DoD plans to utilize the report and DCAT to \u201ccomplete climate exposure assessments on all major U.S. installations within 12 months and all major OCONUS installations within 24 months,\u201d according to the Thursday press release.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A
