Climate Changes
What causes global warming?
As human activity takes place, carbon-dioxide increases.
Scientists believe that artic ice is melting at the rate of ________% every ten years!
13
What is good about the greenhouse effect?
Without the greenhouse effect, Earth would be much too cold for life.
How do people cause climate change?
Human activities - must be specific of a human action
How do volcanoes contribute to global warming?
When they erupt, they release large amounts of Co2
What is carbon footprint?
Carbon footprint is the total amount of greenhouse gases (including carbon dioxide and methane) that are generated by our actions.
Where in our environment specifically, are we seeing the effects of climate change?
Coral reefs, artic regions, oceans, etc.
What is the evidence that global warming may be happening?
Temperature changes in ocean, melting ice caps, arctic animals are dying, changes in weather patterns
This is an atmospheric heating phenomenon in which the Earth experiences rise in temperature because certain gases

Coral bleaching happens when corals lose their vibrant colors and turn white. When water is too warm, corals will expel the algae (zooxanthellae) living in their tissues causing the coral to turn completely white.
How do forests help remove greenhouse gases?
They exchange Co2 for oxygen
These are resources which can be used repeatedly and replaced naturally and almost never run out. Solar energy is an example.
Renewable resources
Give an example how global warming is affecting polar regions
answers will vary
If we continued to damage the Earth, how would that affect life?
The atmoshere would overheat and therefore lifeforms would not have enough time to adapt.
What are 2 alternatives for making electricty that do not contribute to global warming?
Wind, Hydropower, or solar
Climate change and global warming are used interchangeably, however, they are different. How so?
Climate change broadly refers changes in average weather (temperature, precipitation, humidity, wind, severe weather, etc.)
Global warming refers to a rise in the Earth’s average global temperature.
Why are temperatures in the Arctic are rising 2 to 3 times faster than temperatures farther south?
Sea ice reflects more sunlight than does the darker ocean. As the sea ice melts, there's less "white" to reflect the sunlight and more "dark" to absorb it. So the ocean gets a little warmer. And more sea ice melts, and the darker water absorbs even more sunlight and heat.
