Greenhouse Gases and Climate Impact

The video explains the greenhouse effect, which keeps Earth warm by trapping heat in the atmosphere. It compares this to how a greenhouse works. Greenhouse gases like carbon dioxide, water vapor, and methane are crucial for maintaining Earth's temperature. However, human activities, such as burning fossil fuels, increase these gases, leading to climate change. NASA monitors these changes using satellites, helping scientists understand the impact on our climate.

What makes Earth a unique place for life?

• Its distance from the Sun

• The presence of water
