- This smoke could block sunlight, drastically cooling the Earth's surface and harming global ecosystems.
Krakatoa's Global Impact
- The 1883 Krakatoa volcanic eruption lowered global temperature by 2.2 degrees Fahrenheit for about five years.
- It changed weather patterns, doubling rainfall in Los Angeles and turning skies red, inspiring the painting The Scream.
Science Shapes Cold War Policies

- Scientists warned that missile defense could escalate arms races, increasing nuclear war risk with catastrophic climate consequences.
