What's actually the worst greenhouse gas?

The video explains the role of greenhouse gases in Earth's warming, highlighting water vapor, sulfur hexafluoride, methane, and carbon dioxide. Water vapor traps heat but is not the main cause of rising temperatures. Sulfur hexafluoride is potent but rare. Methane is significant due to its abundance. Carbon dioxide is the primary driver of warming due to its high concentration and human activities. The video emphasizes the need to address greenhouse gas emissions to mitigate climate change.

What is the primary role of water vapor in Earth's atmosphere?

• It is the main cause of rising temperatures.

• It traps heat and helps regulate Earth's temperature.

• It is responsible for the majority of global warming.

• It is the most abundant greenhouse gas.

Which greenhouse gas is known for its ability to float a tinfoil boat?

• Water Vapor

• Methane

• Carbon Dioxide

• Sulfur Hexafluoride

How does methane compare to sulfur hexafluoride in terms of warming potential per ton?

• Methane is 7,000 times less potent.

• Methane is 7,000 times more potent.

• Methane is 30,000 times more potent.

• Methane is equally potent.

Why is carbon dioxide considered the most significant greenhouse gas despite its lower warming potential per ton?

• It is the heaviest gas.

• It is synthesized for industrial use.

• It is the lightest gas.

• It is the most abundant and increasing rapidly.

What percentage of warming over the last 250 years is attributed to carbon dioxide?

• 60%

• 50%

• 70%
