Extreme weather and a changing climate

Our climate is changing, and rapidly. The evidence is all around us. One result of our changing climate is the increased frequency of weather and weather-related extremes across the Earth–stifling and dangerous heatwaves, prolonged and profound drought, torrential rain leading to deadly and destructive flooding, inexorable sea level rise, explosive wildfires and then smoke affecting skies, air quality, and health thousands of miles away, lives…

Extreme weather and climate change: the connections and impacts

Is there a connection between extreme weather events (rain, cold, heat, droughts, hail, hurricanes, tornadoes, and more) and climate change? Yes. Are extreme weather events becoming stronger and happening more frequently? Yes. Are these extreme weather events having a greater impact–economic losses, human migration, loss of plant and animal species and even extinction, worsening human health, and more. Yes, again.

There is a much greater flood risk in the United States

Across much of the United States, the flood risk is greater (in some cases, far greater) than what government estimates and maps currently show. As a result, millions of homes and properties and many millions of people are facing a threat they have not thought they faced and may not have known about when they purchased or rented a property–a flooding threat that will only…
