Greenhouse Gases and Climate Change

The video explains the difference between weather and climate, highlighting that climate is the long-term average of weather conditions. It discusses climate change, often referred to as global warming, and its historical context. The greenhouse effect is explained as a natural process that warms the Earth, but human activities like burning fossil fuels, farming, and deforestation increase greenhouse gases, intensifying this effect. The video outlines the impacts of climate change, such as extreme weather and habitat loss, and suggests ways to mitigate these effects, including reducing energy use and planting trees.

What is the main difference between weather and climate?

• Weather is the average condition over a long period, while climate changes daily.
