Climate Change

Higher temperatures cause more evaporation, which causes more water vapor to be in the air. Water vapor is a greenhouse gas, so more water vapor will lead to Earth warming even more. This is an example of...

Which student best explains climate change and how humans impact climate change with their actions?

• Terrell: Carbon dioxide is a greenhouse gas that is released by animal and humans. This proves that greenhouse gases are not harmful and don't affect the climate.

• Brenda: Climate change only happens during the summer months when temperatures reach up to 100ºF. Winters are still cold, so humans impact the climate less in the winter than summer.

• Isabella: When the amount of greenhouse gases in the atmosphere increases, they warm the Earth. This change in climate causes ice caps to melt, habitat destruction, and severe weather changes like droughts.

• Jeremy: Humans do not have an impact on climate change but plants do. Global warming creates the perfect climate for plants to grow all around the globe. More plants means warmer Earth.
