Coastal military bases, federal crop insurance and federal disaster aid: These government programs are vulnerable to the effects of climate change—enough that the Government Accountability Office has placed the fed's financial vulnerability to climate change-related weather events on a "high risk" list.
A report released today cites observations by the United States Global Change Research Program (USGCRP) that the "impacts and costliness of weather disasters—resulting from floods, drought, and other events such as tropical cyclones—will increase in significance as what are considered 'rare' events become more common and intense due to climate change. In addition, less acute changes in the climate, such as sea level rise, could also result in significant long-term impacts."
The government could have to raise river and coastal dikes and build higher bridges to protect infrastructure from sea level rise.
That will cost money, as will federal disaster aid. Disaster declarations have increased in recent decades, the report says, and the Federal Emergency Management Agency (FEMA) has obligated over $80 billion in federal assistance for disasters declared during fiscal years 2004 through 2011. More than $60 billion in federal funding was requested for relief efforts after Hurricane Sandy.
How can the government reduce the nation's vulnerability to climate change? Limit greenhouse gas emissions, the report concludes.
