Episode notes
Listener Question: Oceans and Temperature
- Mark from Maidenhead questions the oceans' influence on global temperature.
- He wonders what the temperature would be without oceans and if they mask global warming.
Oceans' Warming Effect
- Without oceans, Earth's average temperature would be -18°C due to less water vapor.
- Water vapor traps heat, contributing significantly to the greenhouse effect.
Ocean as Climate Control
- The ocean acts as a buffer, absorbing excess energy without significant temperature change.
- Ocean currents distribute this energy around the planet, influencing global climate.
