Name 2 NATURAL causes global warming?
Carbon-dioxide is released from Trees. Volcanic eruptions that releases CO2 in the atmosphere. The Earth's position in space.
100
Name one common greenhouse gas
Carbon Dioxide, Methane
100
Name the most common way nature contributes to global warming.
When animals breathe they release Carbon Dioxide Or When cows fart
100
What are two common ways of transportation that does not add to global warming?
Walking and Biking
100
proponents
Who believes that the increase human population has affected global warming
200
How do people cause climate change?
Humans use energy (coal and oil) and release carbon dioxide into the air. Cows release methane into the air.
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.
200
Decrease the saline level of the oceans
What effect would a substantial amount of sweet water entering the oceans from melting glaciers have?
300
How can earth's forests affect global warming?
If trees are cut down, they release carbon dioxide and therefore deplete the amount of oxygen in the atmosphere, since live trees take in CO2 and let out oxygen.
300
How are animals affected by greenhouse gases (which change the temperature of the earth)?
Some animals can only live in cold temperatures and if temperature rises, they can become extinct
300
Cows
Which animal causes methane because of its farts?
300
How might cold-water animal species respond to the increase of temperature in their waters?
Many of the species could die off, migrate, and break patterns of life cycles.
300
Can greatly affect the food chain
What can a rise in global temperature do to affect animal life?
400
Name the 2 main Greenhouse gases
CO2, methane
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 forests contribute to the removal of greenhouse gases?
They respirate by exchanging Co2 for oxygen
400
Who believes that the rapid rate at which CO2 levels have risen is a major factor in Global Warming?
Proponents of Global Warming
400
There has been no significant change in U.S. droughts in the last 50 years
What would a detractor say about weather pattern changes?
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 atmoshere would overheat and therefore Polar Caps would melt changing the ocean currents which would change the weather patterns and create tornados, etc. Massive areas of earth would be flooded.
500
Was there a time when CO2 levels were low but the temperature higher than or the same as today?
Yes, in Roman and Medieval times
500
Do Proponents and Detractors of Global Warming 'both' agree that CO2 levels risen in the past 100 years?
Yes
500
