Climate toll on Arctic bases: Sunken runways, damaged roads

WASHINGTON (AP) — U.S. military bases in the Arctic and sub-Arctic are failing to prepare their installations for long-term climate change as required, even though soaring temperatures and melting ice already are cracking base runways and roads and worsening flood risks up north, the Pentagon's watchdog office said Friday.

The report from the inspector general of the Department of Defense provides a rare bit of public stock-taking of the military’s state of readiness – or lack of readiness – for the worsening weather of a warming Earth.

The U.S. military long has formally recognized climate change as a threat to national security. That's in part because of the impact that intensifying floods, wildfires, extreme heat and other natural disasters are having and will have on U.S. installations and troops around the world.

Increasing hurricanes, flooding, storms and wildfires in recent years have caused billions of dollars in damage to Florida's Tyndall Air Force Base, Nebraska's Offutt Air Force Base and other U.S. military installations, and interrupted training and other operations.

For years, laws, presidential orders and Pentagon rules have mandated that the military start planning and work so that its installations, warships, warplanes and troops can carry out their missions despite increasingly challenging conditions as the use of fossil fuels heats up the Earth.

While even acknowledging climate change was a career risk for administration officials under former President Donald Trump, President Joe Biden directed faster, more sweeping action on climate change by the Department of Defense and other agencies as one of his first acts in office.

Despite Biden’s emphasis, inspectors visiting the United States’ six northernmost military bases last June and July found...
