Greenhouse Gases and Climate Change

The video explains climate change, focusing on greenhouse gases like CO2, methane, and CFCs. It distinguishes between global warming and climate change, highlighting historical climate cycles. Evidence such as rising sea levels, melting glaciers, and extreme weather events is presented. The video discusses the impact on oceans, including acidification and thermohaline circulation disruption. It concludes with challenges in addressing climate change, emphasizing the need for policy changes and alternative energy sources.

Which gas is the most abundant greenhouse gas in the atmosphere?

• Carbon Dioxide

• Methane

• Water Vapor

• Nitrous Oxide

What human activities have significantly increased carbon dioxide levels since the industrial revolution?

• Running and heavy breathing

• Deforestation and burning fossil fuels

• Volcanic eruptions

• Natural gas leaks

How much more effective is methane at trapping heat compared to carbon dioxide?

• 20 times

• 15 times

• 10 times

• 5 times

What is the primary difference between global warming and climate change?

• Global warming is a short-term phenomenon, while climate change is long-term

• Global warming refers to temperature increase, while climate change includes broader changes

• Global warming is caused by natural factors, while climate change is human-induced

• Global warming affects only certain regions, while climate change affects the entire planet

What has been the trend in sea level rise over the last century?

• Decreased by 17 cm

• Remained constant

• Increased by 17 cm

• Increased by 3 mm

What is one of the consequences of melting glaciers and polar ice caps?

• Decrease in global temperatures

• Increased agricultural productivity

• Migration of animal species

• Stabilization of sea levels

What role does the ocean conveyor belt play in the Earth's climate?

• It stabilizes the Earth's orbit

• It regulates the flow of heat from tropical to polar regions

• It increases the acidity of the oceans

• It reduces the amount of greenhouse gases

What could happen if the ocean conveyor belt stops functioning properly?

• Oceans becoming stagnant and oxygen-depleted

• Formation of new landmasses

• Decrease in sea levels

• Increase in global temperatures

What is a major challenge in addressing climate change?

• Overpopulation

• Misinformation and vested interests

• Lack of scientific evidence

• Insufficient technological advancements

Which countries are the largest emitters of greenhouse gases?

• India and Brazil

• Russia and Japan

• China and the United States

• Germany and Canada
