Climate, Weather, and Global Warming
Give an example of "weather"
Answers will vary. Examples: Rain, sunshine, cloudy
Why do scientists take out ice cores?
What is the most abundant (common) greenhouse gas?
Water vapor
What is "CO2"?
Carbon dioxide
How much has the Earth's temperature increasing by since 1980?
0.8 degrees celsius
Describe Victoria's climate
Rainy, no "extreme" temperatures, not much snow
What is happening to ocean temperatures because of climate change?
They are warming
True or False: No heat gets launched back to space
True
Source - fire, humans, decomposition, respiration
Sinks - plants, trees, ocean
What is the main source of greenhouse gases?
Manufacturing
What is the difference between climate and weather?
Weather can change quickly; Climate is what you would expect over the long-term
What is happening to ice sheets because of climate change?
True or False: Some heat gets trapped and re-radiated back onto Earth
True
Describe the carbon cycle in simple terms. What happens during the carbon cycle?
Process that moves carbon between living things, atmosphere, and ocean in a cycle
True or False: Sea levels will lower because of climate change
False
What is something that could happen because of global warming?
Global temperature increases, melting glaciers, damage oceans (could be more correct answers)
Describe "glacial retreat"
Glaciers shrink and look like they are moving backwards
What happens when greenhouse gases increase?
More heat gets trapped in the Earth, increasing surface temperature
Name a release agent
Volcanoes, humans, lightning
How will farmers be affected by climate change?
More droughts and changes in precipitation will affect their crops
What is the difference between climate change and global warming?
Global warming refers just to increasing temperatures; Climate change is a wide range of impacts and events
Increased carbon dioxide leads to ocean absorbing more CO2
Why is methane dangerous?
It can lead to explosions
What would happen if carbon sinks outnumbered carbon sources?
Where is most ozone in the atmosphere?
Stratosphere
