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…
