2. What role do greenhouse gases play in the greenhouse effect?


Can anyone tell me what the greenhouse effect means? Explanation: The greenhouse effect refers to the process by which greenhouse gases absorb and re-emit thermal radiation, trapping heat near Earth's surface. This effect is essential for regulating the Earth's climate and maintaining the temperatures within a range that can support life. Without the greenhouse effect, the planet's average temperature would be much colder, making it uninhabitable for most life forms on Earth. However, human activities, such as burning fossil fuels and deforestation, have led to an increase in greenhouse gas concentrations in the atmosphere, causing global warming and other climate changes. It is crucial that we take action to reduce our greenhouse gas emissions to mitigate the negative impacts on our planet.
