Quarter 3 – Module 5: Global Climate Phenomenon

Which of the following is a greenhouse gas?

• CO2
• CH4
• water vapor
• all of these

Which of the following can cause global warming?

• Volcanic eruptions
• The amount of rainfall
• The rising of warm air into the atmosphere
• Increase of the amount of carbon dioxide in the atmosphere

Which of the following are consequences associated with climate change?

• Global sea levels are arising at an alarming fast rate.
• Surface temperatures are setting new heat records about each year.
• The ice sheets are declining, glaciers are in retreat globally & our oceans are more acidic than ever.
• All of the above.

What can you do to help fight climate change?

• Divest from fossil fuel companies.
• Engage yourself in the science behind climate change.
• Vote for political candidates who will advocate for climate-related legislation & policy improvements.
• All of the above

Globally, which of the following economic sectors emits the largest percentage of greenhouse emission?

• industry
• buildings
• transportation
• electricity and heat production

Which activity does not contribute to global warming?

• Reforestation
• mining activities
• Illegal fishing
• incineration of garbage

How can extreme events like hurricanes, drought and wildfire impact energy infrastructure?

• Power outages
• higher electricity and gas prices
• Water shortages
• all of these

Why are forests important for mitigating climate change?

• Trees are important food source
• Trees provide building materials.
• Forest serves as a sink in the carbon cycle.
• Leaves of trees reflect all sunlight away from the earth.

If greenhouse effect is natural, then why is today’s climate change a bad thing?

• A small increase in greenhouse gas concentration can have a large effect of increased warming.
• Humans have altered a natural process and exaggerated changes that might normally occur over millions of years.
• Once released into the atmosphere, greenhouse gases remain potent for many years, making it difficult to reverse the process.
• All of the above.

If we stopped burning fossil fuels today, what would happen to the climate?

• Earth’s average temperature would immediately cool.
• Temperatures would slowly cool over the next 5 years.
• Temperatures would fluctuate, but stay the same on average
• Temperatures would continue to rise at least 10 years, and then would level off.
