Climate Adaptation and EPA’s Role

Definitions
  • Climate change refers to changes in global or regional climate patterns attributed largely to human-caused increased levels of atmospheric greenhouse gases.
  • Climate change adaptation or climate adaptation means taking action to prepare for and adjust to both the current and projected impacts of climate change.
  • Climate change mitigation refers to actions limiting the magnitude and rate of future climate change by reducing greenhouse gas emissions and/or advancing nature-based solutions.
  • Adaptive capacity is the ability of a human or natural system to adjust to climate change (including climate variability and extremes) by moderating potential damages, taking advantage of opportunities, or coping with the consequences.
  • Climate resilience can be generally defined as the capacity of a system to maintain function in the face of stresses imposed by climate change and to adapt the system to be better prepared for future climate impacts.

Climate change adaptation or climate adaptation means taking action to prepare for and adjust to both the current and projected impacts of climate change. The impacts of climate change affect people in every region of the country. These impacts threaten lives and livelihoods and damage infrastructure, ecosystems, and social systems.

The last few years have seen:

  • Climate-related, record-breaking weather extremes.
  • Increased droughts, flooding, and wildfire.
  • Increasing surface, atmospheric, and oceanic temperatures.
  • Melting glaciers.
  • Diminishing snow cover.
  • Shrinking sea ice.
  • Rising sea levels.
  • Ocean acidification.
  • Increasing atmospheric water vapor.

Climate change also exacerbates existing pollution problems and environmental stressors impacting the nation’s land, air, and water and the people who depend on them. Low-income communities, children, the elderly, Tribes, Indigenous people, and geographic areas such as coastal regions are at higher risk from hazards and impacts.

Changes to environmental functions pose significant risks to EPA’s ability to fulfill its mission and affects how it designs and implements its programs. EPA is working to ensure that its programs, policies, rulemaking processes, enforcement and compliance assurance activities, and operations consider the current and future impacts of climate change and how those impacts will disproportionately affect some communities.
