Climate Change Is Making Everything Worse

Rising seas are amplifying risks everywhere, especially in the Pacific Northwest. Higher water levels allow these waves to reach farther inland, while protective beaches steadily wash away. Combine rising seas with Pacific Northwest land sinking and you get compound flooding worse than either disaster alone. Recent studies show that 3 to 7 inches of sea level rise caused 70% more beach erosion during El Niño, a preview of our climate-changed future.
