Answer :
Final answer:
Human activities intensify the greenhouse effect, causing climate change impacts like heatwaves and droughts.
Explanation:
Human activities have intensified the greenhouse effect by increasing carbon dioxide concentrations in the atmosphere through burning fossil fuels. This leads to the trapping of heat energy, resulting in global warming, changing precipitation patterns, and more extreme weather events such as heatwaves, droughts, and wildfires.
The top three greenhouse gases in Earth's atmosphere in terms of their effect on climate are carbon dioxide, methane, and nitrous oxide.
Overall, human-induced changes in the greenhouse effect are significantly impacting the Earth's climate, leading to detrimental consequences like disrupted ecosystems, rising sea levels, and endangering human security across regions.
