The Fourth National Climate Assessment makes it clear that we’re already experiencing the impacts of climate change in the United States. Here are four examples:…
1. The average length of the heat wave season across 50 cities in the US has roughly tripled since the 1960s. #NCA4 #ClimateScienceFacts
2. From 1984-2015, the total forest area burned by wildfires in the American West was twice what it would’ve been without climate change, which has dried out forests in the region, making them more vulnerable to catching fire. #NCA4 #ClimateScienceFacts
3. As oceans have warmed and land ice has melted, annual median sea level along the U.S. coast has increased by approximately 9 inches since the beginning of the 20th century. #NCA4 #ClimateScienceFacts
4. More of the US now gets a greater percentage of its total annual precipitation from intense single-day events (downpours) than in the past. #NCA4 #ClimateScienceFacts
These changes are having profound effects across the United States in the form of worsening heat waves, wildfires, and flooding – with huge consequences for our economy, infrastructure, and health. #NCA4 #ClimateScienceFacts
Write your members of Congress today to convey how climate change impacts you and your community and urge them to be briefed on #NCA4.
