Global Climate Change

Mr. Anderson discusses global climate change, focusing on the causes, such as solar radiation and greenhouse gases, and the rapid changes due to human activities. He explains the greenhouse effect, the role of natural and anthropogenic sources, and the environmental and human impacts. International efforts like the Kyoto Protocol and Paris Agreement aim to reduce greenhouse gases, though challenges remain. The video emphasizes the need for global cooperation to address climate change effectively.

What are the two main factors that influence global climate change?

• Air pollution and water pollution

• Solar radiation and the greenhouse effect

• Ocean currents and volcanic activity

• Deforestation and urbanization

Which international agreement was the first to address the reduction of greenhouse gases?

• Copenhagen Accord

• Kyoto Protocol

• Paris Agreement

• Montreal Protocol

What is the primary function of greenhouse gases in the atmosphere?

• They reflect sunlight back into space.

• They trap infrared radiation, warming the planet.

• They absorb ultraviolet radiation.

• They cool the Earth's surface by blocking sunlight.

• Carbon dioxide

• Oxygen

• Methane

• Nitrous oxide

What are some predicted environmental impacts of rising global temperatures?

• Increased snowfall and longer winters

• Expansion of polar ice caps

• Melting glaciers and rising sea levels

• Decreased storm intensity

How might climate change affect human health according to the video?

• Improvement in overall public health

• Spread of diseases like malaria to new areas

• Reduction in vector-borne diseases

• Decrease in respiratory diseases

What is the main goal of the Paris Agreement regarding global temperature rise?

• To increase the use of renewable energy by 50%

• To keep the global temperature rise below 2 degrees Celsius

• To eliminate all greenhouse gas emissions by 2050

• To reduce deforestation by 30%
