Intro to Climate Change
Fun Facts
- Greenhouse gases trap thermal energy similar to how the glass in greenhouses that farmers use to grow plants traps sunlight.
- Moving from fossil fuels to renewable energy resources can help decrease the amount of greenhouse gases humans put into the air.
- 97% of climate researchers agree that the increase in global temperatures is caused by increased greenhouse gases from human activity.
Why Do We Need To Know About Greenhouse Gases
Learning about greenhouse gases helps us understand their role in climate change and why it’s important to use less fossil fuels. Greenhouse gases are natural but have increased a lot because of people using fossil fuels for energy. This has caused global warming and climate change, so we need to find cleaner energy sources.
Scientists and engineers are working on new energy ideas like making fuel from plants, making nuclear power safer, and making solar panels more efficient. These projects aim to lower the gases that cause climate change by using cleaner energy. This shows how creating new technologies is key to fighting climate change and offers many jobs in science fields.
