Global warming is a:
- Gradual increase in the average temperature of the earth's lower atmosphere
Explanation:Global warming refers to the long-term increase in the average temperature of the Earth's lower atmosphere, also known as the troposphere. Here are some key points to support this answer:
1. Greenhouse Effect: Global warming is primarily caused by the greenhouse effect. Human activities, such as burning fossil fuels and deforestation, release greenhouse gases like carbon dioxide into the atmosphere. These gases trap heat from the sun, leading to a gradual increase in temperatures.
2. Temperature Records: Over the past century, there has been a significant rise in global temperatures. Various scientific studies, including those conducted by NASA and the Intergovernmental Panel on Climate Change (IPCC), have documented this increase.
3. Climate Change: Global warming is a key driver of climate change. As average temperatures rise, it affects weather patterns, sea levels, and ecosystems. Increased temperatures can lead to more frequent and intense heatwaves, droughts, storms, and other extreme weather events.
4. Scientific Consensus: The overwhelming majority of climate scientists agree that global warming is occurring and is primarily caused by human activities. This consensus is based on extensive research, data analysis, and peer-reviewed studies.
It is important to address and mitigate global warming to prevent further damage to the environment, ecosystems, and human well-being. Transitioning to renewable energy sources, reducing greenhouse gas emissions, and promoting sustainable practices are crucial steps in combating global warming.
