What is global warming?
Global warming is the increase of Earth's average surface temperature due to greenhouse gases, such as carbon dioxide emissions from burning fossil fuels or from deforestation, which trap heat that would otherwise escape from Earth.
100
Name one common greenhouse gas
Carbon Dioxide
100
Name the most common way animals contribute to global warming.
When animals breathe they release Carbon Dioxide
100
What are two common ways of transportation that does not add to global warming?
Walking and Biking
200
In the last century, how high did sea levels rise?
In the last century, sea levels rose roughly 7 inches after not having changed noticeably in the previous 2,000 years.
200
What are greenhouse gases?
Gases trapped in the atmosphere
200
How do volcanoes contribute to global warming?
When they erupt, they release large amounts of CO2
200
How does planting trees help reduce carbon dioxide levels?
They take in CO2 and release oxygen via photosynthesis.
300
True or False: There is more carbon dioxide in the atmosphere today than at any point in the last 800,000 years.
True
300
How are animals affected by greenhouse gases?
Some animals can only live in cold temperatures and if temperature rises, they can become extinct
300
How do forests (trees) contribute to the removal of greenhouse gases?
They exchange CO2 for oxygen
300
How are cold-water animal species responding to the increase of temperature in their waters?
Many of the species are dying off, migrating, and breaking patterns of life cycles.
400
Name 3 Greenhouse gases
CO2, methane, water vapor, or nitrous oxide
400
How are green houses gases linked to global warming?
The green house gases get traped in the atmosphere, therefore making the temperatures rise
400
How do the wetlands affect global warming?
They release methane gas, another greenhouse gas, into the air.
400
True or False: The organism bacteria helps prevent the accumulation of CO2
True
500
How will climate change affect the ocean?
Polar Ice caps may melt therefore increasing ocean levels.
500
If we continued to damage the earth, how would that affect life?
The atmosphere would overheat and therefore life forms would not have enough time to adapt.
500
What are 3 global effects of Global Warming?
Temperature increase, disappearing glaciers, violent storms, ecological crisis or catastrophic events on humanity
500
Name 3 ways to prevent Global Warming
Burn less fossil fuel by going in for fuel-efficient small cars, or even better, using public transport, reduce energy consumption by switching off appliances when not needed, use energy-efficient light bulbs and heating devices, minimize the use of timber-based products such as paper, and fossil-based products such as plastic, recycle paper and plastic products
