Climate Change

Adaptation Overview

Key Adaptation Terms

Adaptation - Adjustment in natural or human systems to a new or changing environment that takes advantage of beneficial opportunities or moderates negative effects.

Adaptive capacity - The ability of a system to adjust to climate change (including climate variability and extremes) to moderate potential damages, take advantage of opportunities, or cope with the consequences.

Resilience - A capability to anticipate, prepare for, respond to, and recover from significant threats with minimum damage to social well-being, the economy, and the environment.

Vulnerability - The degree to which a system is susceptible to, or unable to cope with, adverse effects of climate change, including climate variability and extremes. Vulnerability is a function of the character, magnitude, and rate of climate variation to which a system is exposed, its sensitivity, and its adaptive capacity.

Climate change is already impacting societies and ecosystems around the world. Many impacts are expected to grow in geographic scale, rate, or intensity as global temperatures continue to increase. Individuals, organizations, and communities can take many steps to adapt to a changing climate—and to help plants and animals cope as well. Some animals and plants will adjust to climate change, such as by expanding their range or changing their migration patterns. Others may struggle and need help from people to survive.

Examples of Adaptation

Adaptation measures are already in place in many areas, as the examples below show. These actions can be expanded or modified to prepare for climate change. But additional measures, such as new technologies and policies, may also be needed. Such actions could require time and resources to carry out, so planning now is important.

Agriculture and Food Supply

Tall, healthy corn stalks in a sunny field.
  • Develop crop varieties that are more tolerant of heat, drought, or flooding from heavy rains.
  • Provide more shade and air flow in barns to protect livestock from higher summer temperatures.

Coasts

Waves crash onto a road along the shore as a car drives by.
  • Preserve wetlands and open spaces to protect coastal communities from flooding and erosion from storms and sea level rise.
  • Improve evacuation planning for low-lying areas to prepare for increased storm surge and flooding.

Ecosystems

A stream cascades downhill through the forest with rocky, moss-covered banks.
  • Protect and expand wildlife habitats to allow species to migrate as the climate changes.
  • Reduce pollution, habitat loss, and other stressors that make ecosystems more vulnerable to climate change.

Energy

Large wind turbines in a field with yellow flowering canola plants.
  • Increase energy efficiency to help offset rises in energy consumption, such as from more air conditioning use as temperatures warm.
  • Strengthen energy production facilities to withstand increased flood, wind, lightning, and other storm-related stresses.

Human Health

Central Park in New York City, with skyscrapers in the background.
  • Set up early warning systems and emergency response plans to prepare for more extreme weather events.
  • Educate people to help them avoid diseases that could become more prevalent as the climate changes, such as those carried by mosquitoes or ticks.
  • Plant trees and expand green spaces in cities to reduce the "urban heat island" effect.

Water Resources

A center-pivot irrigation system in a field of crops.
  • Improve water use efficiency, and build additional water storage capacity.
  • Protect and restore stream and river banks to provide wildlife habitat and safeguard water resources.
