Final answer:
A potential method for global warming is the emission of greenhouse gases. The Kyoto Protocol is a famous protocol addressing global warming. The trading system refers to carbon trading.
Step-by-step explanation:
A potential method for global warming is the emission of greenhouse gases, such as carbon dioxide, into the atmosphere. These gases trap heat from the sun and cause the Earth's temperature to rise.
One famous protocol aimed at addressing global warming is the Kyoto Protocol. It was an international agreement that set targets for reducing greenhouse gas emissions, with the goal of combating climate change.
The trading system in the context of global warming refers to carbon trading. This system allows countries, companies, and organizations to buy and sell permits that allow them to emit a certain amount of greenhouse gases. It is a market-based approach designed to provide economic incentives for reducing emissions.
