U.S. National Adaptation And Resilience Planning Strategy
The devastating impacts of climate change are being felt by every country and continent on Earth. Across the United States, climate change is accelerating the frequency and fueling the severity of extreme weather events, resulting in tragedies and new realities that once seemed unimaginable.
In 2024 alone, Phoenix, Arizona, experienced 113 consecutive days of temperatures in excess of 100 degrees Fahrenheit, leading to heat emergencies that disrupted schools and businesses. Devastating floods in Iowa and Minnesota forced thousands to evacuate and wiped out roads and rail lines. Hurricanes, supercharged by warm ocean water, ravaged communities in the Southeast, killing hundreds and cutting communities off from power and water. Raging wildfires in New Mexico, Oregon, and California destroyed entire neighborhoods. Communities in every corner of the country are being directly impacted by the effects of climate change.
Even minor increases in temperature create worse economic outcomes: workers exposed to more heat risk adverse workplace outcomes, including more frequent injury and death. In addition to posing direct threats to lives and livelihoods, extreme weather events – which are becoming increasingly extreme due to the climate crisis – have had significant economic impacts. In 2024, the United States experienced 27 disasters costing $1 billion or more, for a total of $182.7 billion in damages. This is the fourth highest cost total recorded since the National Oceanic and Atmospheric Administration started collecting this data, and nearly twice the cost of disasters in 2023.
These are the consequences of living on a rapidly warming planet. In the United States, temperatures have already risen by 2.5 degrees Fahrenheit in the contiguous states and by 4.2 degrees Fahrenheit in Alaska since 1970. Relative to the early 20th century (1901-1960), in the last two decades, areas of the central and eastern United States are 5-15% wetter, while the Southwest and Hawaiʻi are 10-15% drier.
Even as the world works to limit future pollution, greenhouse gas emissions, and temperature rise, all countries, regardless of their geographic location or development status, will need to adapt to the impacts of a changing climate. National adaptation planning is critical to enable and accelerate the adjustments needed to prepare for and manage the immediate, medium-, and long-term effects of climate change.
Accordingly, the Biden-Harris Administration has taken historic steps to provide the federal support, resources, and investments needed to help America’s communities meet the climate challenges of today—and prepare for the climate challenges of tomorrow. In his first week in office, President Biden signed Executive Order 14008, Tackling the Climate Crisis at Home and Abroad, mobilizing the first-ever, whole-of-government approach to addressing climate change. In addition, the Bipartisan Infrastructure Law and the Inflation Reduction Act are supporting the implementation of adaptation by investing roughly $50 billion to advance climate resilience strategies in communities across America.
