Global Warming and Climate Change
In this video, the professor explains the concepts of the greenhouse effect, global warming, and the role of greenhouse gases in warming the Earth’s surface.
The greenhouse effect is illustrated by the example of a greenhouse where the glass allows solar radiation to enter but blocks the infrared radiation emitted by the interior surfaces, leading to a rise in temperature. Similarly, greenhouse gases like carbon dioxide, water vapor, and others trap the heat radiated from the Earth’s surface, causing global warming. The paragraph also highlights that the global temperature has increased by 0.8 degrees Celsius from 1860 to 2000 and is estimated to have been 1.24 degrees Celsius in 2022.
Review questions:
- What is the greenhouse effect, and how does it contribute to global warming?
- What is the trend in global temperature over the past century, and what are the implications of this trend?
