Reduced Air Pollution Is Heating the Planet

Clouds reflect less sunlight Oceans absorb more heat A surprising climate twist

Cleaner Air, Hotter Planet

Less pollution = fewer aerosols Clouds lose brightness More sunlight reaches oceans

Global Pollution Levels Dropped Sharply

SO₂ emissions falling China, US, Europe improved air Worldwide aerosol decline

Clouds Are Becoming Dimmer

Cloud brightness falling 3% per decade Droplets becoming larger Clouds raining out faster

The Science Behind Dimmer Clouds

Twomey effect

Albrecht effect

Combined = weaker cooling

Oceans Absorb More Heat

– Stronger marine heatwaves – Warmer surface temps – Ecosystems stressed
