Final answer:
Global warming refers to the long-term increase in the average temperature of the Earth's atmosphere and oceans. It is caused by the release of greenhouse gases from human activities and has negative impacts on the environment and climate system.
Step-by-step explanation:
Global Warming
Global warming refers to the long-term increase in the average temperature of the Earth's atmosphere and oceans. It is primarily caused by the release of greenhouse gases, such as carbon dioxide, into the atmosphere from human activities like burning fossil fuels and deforestation.
These greenhouse gases trap heat from the sun, leading to a rise in temperature and disrupting the Earth's climate system. This has numerous negative impacts, including the melting of polar ice caps, rising sea levels, more frequent and severe weather events, and changes in ecosystems.
Addressing global warming requires reducing greenhouse gas emissions, transitioning to renewable energy sources, conservation efforts, and international cooperation to mitigate its effects.
