  • Respond: Check for and remove ticks promptly after coming indoors. Remember that pets may bring ticks into the house.
  • Respond: Wear protective clothing (such as high boots and long sleeves and pants), and consider using insect repellent.

Most of Virginia has warmed 1°F in the last century, and sea level is rising one to two inches every decade. These, and other climate impacts, mean increasing risks to health. Examples of risks and actions for Virginia residents include:

• Higher temperatures and other weather changes will increase levels of ozone pollution (a component of smog), increasing health risks like asthma-related hospital visits. Learn how you can take action to protect against poor air quality, such as:
  • Prepare: Check news or airnow.gov for the local air quality index.
  • Respond: Reduce outdoor activity when pollution levels are high.


• More carbon dioxide causes some plants to produce more pollen. This will combine with longer growing seasons and other changes to result in more allergy and asthma episodes. Learn how you can take action to prevent asthma attacks and allergy symptoms, such as:
  • Respond: Limit time outdoors based on air quality reports, pollen and mold counts, and heat advisories.
  • Prepare: Clean and replace air conditioner filters often.


• More intense hurricanes can disrupt infrastructure (damage to roads, bridges, or utilities), which can prevent access to health care. Learn how you can take action to manage infrastructure disruptions, such as:
  • Respond: Check the news for tap water safety notices, such boiling water before use.
  • Respond: Avoid fallen power lines.
  • Respond: Keep power generators outside to avoid fire and carbon monoxide risks.

Over the past century, most of Washington has warmed 1°F to 2°F. This and other climate impacts, like more intense wildfires, mean increasing risks to health. Examples of risks and actions for Washington residents include:

• Large wildfires are occurring more often, and wildfire seasons are lasting longer. This increases health risks such as those related to smoke inhalation and evacuations. Learn how you can take action to protect against wildfires, such as:
  • Prepare: Keep your air-conditioning filter clean, and close the unit's fresh air intake.
  • Respond: Check local news and reports for information on air quality, visibility, and evacuation orders.


• More floods will occur in some mountain watersheds. Floods can lead to illness, injury, and deaths. Learn how you can take action to protect against floods, such as:
  • Respond: Fill bathtubs, sinks, and plastic containers with clean water.
  • Respond: Avoid driving or walking in or near flood waters, even after the flood or during cleanup.


• Harmful algal blooms that contaminate shellfish have become more frequent along the Pacific Northwest coast and estuaries. Rising temperatures will lengthen the season for harmful blooms in the Puget Sound. This especially affects tribes that traditionally depend on shellfish harvests. Learn how you can take action to ensure food safety, such as:
  • Prepare: Check for beach closures or health department notices before swimming, fishing, or harvesting shellfish.
  • Respond: Keep seafood chilled to less than 38°F. Discard any perishable food if your refrigerator has lost power for longer than four hours.

Most of West Virginia has warmed 0.5°F to 1°F in the last century and heavy rainstorms are becoming more frequent. These, and other climate impacts, mean increasing risks to health. Examples of risks and actions for West Virginia residents include:

• Higher temperatures and other changes will increase levels of ozone pollution (a component of smog), increasing health risks like asthma-related hospital visits. Learn how you can take action to protect against poor air quality, such as:
  • Prepare: Check news or airnow.gov for local air quality reports.
  • Respond: Reduce outdoor activity when pollution levels are high.


• Longer warm seasons mean that ticks carrying Lyme disease will emerge earlier in the season and move into new areas. Learn how you can take action to protect against ticks, such as:
  • Respond: Check for and remove ticks promptly after coming indoors. Remember that pets may bring ticks into the house.
  • Respond: Wear protective clothing (such as high boots and long sleeves and pants), and consider using insect repellent.


• More intense rain can overwhelm combined sewer systems (where storm water and sewage share pipes). This can contaminate recreational water and sources of drinking water and lead to disease outbreaks. Learn how you can take action to ensure drinking water safety, such as:
  • Prepare: Have an emergency water supply ready for your family (1 gallon per person/pet per day).
  • Respond: Check the news for tap water safety notices, such as boiling water before use.

In the past century, most of Wisconsin has warmed about 2°F and heavy rainstorms are becoming more frequent. These, and other climate impacts, mean increasing risks to health. Examples of risks and actions for Wisconsin residents include:

• More intense rain can overwhelm combined sewer systems (where storm water and sewage share pipes). This can contaminate recreational water and sources of drinking water. Learn how you can take action to ensure drinking water safety, such as:
  • Prepare: Have an emergency water supply ready for your family (1 gallon per person/pet per day).
  • Respond: Check the news for tap water safety notices, such as boiling water before use.


• Heat-related illnesses, hospital visits, and deaths will increase. Learn how you can take action to protect against heat waves, such as:
  • Respond: Drink plenty of water.
  • Respond: Watch for signs of dehydration and overheating, especially in children.


• Longer warm seasons mean that ticks will emerge earlier in the season. Already common in the Midwest, Lyme disease infections will increase. Learn how you can take action to protect against ticks, such as:
  • Respond: Check for and remove ticks promptly after coming indoors. Remember that pets may bring ticks into the house.
  • Respond: Wear protective clothing (such as high boots and long sleeves and pants), and consider using insect repellent.


• For Ojibwe peoples, rising temperatures and ecosystem impacts threaten culturally and economically important species like wild rice and moose.

In the past century, most of Wyoming has warmed by 1°F to 3°F and heat waves are becoming more common. These, and other climate impacts, mean increasing risks to health. Examples of risks and actions for Wyoming residents include:

• Higher temperatures will increase heat-related illnesses, hospital visits, and deaths. Learn how you can take action to protect against heat waves, such as:
  • Respond: Drink plenty of water.
  • Respond: Watch for signs of dehydration and overheating, especially in children.
  • Respond: Check on elderly neighbors or anyone else who may need assistance.


• More frequent and intense droughts make it easier for soil dust to become airborne. Dust storms lower air quality and cause breathing and visibility problems. Learn how you can take action to protect against dust storms, such as:
  • Respond: Seek shelter immediately.
  • Respond: Stay low, and cover eyes, nose, and mouth.
  • Respond: When driving, be alert for sudden changes in visibility. Pull off the roadway, or reduce speed.
