How do volcanic eruptions affect weather?
Gases and particles may block sunlight and lower temperatures.
What happens as a result of the oceans absorption of carbon dioxide?
It causes a cooling effect
What is one of the criticisms of the Kyoto Protocol?
It only requires developed nations to reduce emissions.
