Fossil Fuels
This is the most destructive method of coal mining.
Mountaintop removal
Solar panels
This weather is caused by burning too much fossil fuel.
Smog or Acid Rain
Blocking this might reduce global warming, but could cause problems with growing plants.
Sunlight
Besides burning for energy, this fossil fuel can be used to make plastic.
Petroleum
Offshore wind means the wind turbines are located here.
in the sea, off the coast
Some countries have small populations, but high carbon emissions, meaning they have high _______ carbon emissions.
Per Capita
What does Geoengineering mean?
changing the environment directly to control climate change
Methane
This is the name for burning trees for energy.
Biomass
Double Double! Explain at least three different dangers caused by global warming.
Ice caps melting / sea-level rise
Worse harvests (famine)
Animal habitats dying off
More severe storms
Not enough water (drought)
It will get harder to reverse
This method uses trees or machines to remove carbon dioxide from the air.
Carbon Capture & Storage
Fossil fuels are formed by this stuff decomposing over millions of years.
dead plants and animals
This is the name for using hot springs and Earth's natural heat to make energy.
Geothermal
Explain one reason why it's difficult to stop using fossil fuels.
Alternate energies may be
expensive
inefficient
not available all the time
people might lose jobs
This is the term for putting iron or other chemicals into the oceans to encourage algae to grow and breathe carbon dioxide out of the air.
Iron seeding
Which century did humans start using fossil fuels in large amounts?
19th Century
This element can be used in nuclear power plants, and is much cheaper and safer than other elements.
Thorium
A tipping point is a moment when it becomes impossible to do this about climate change.
reverse, stop
Explain at least two reasons why limiting or reducing human population might not be a good solution.
One child policies can cause imbalance populations.
Population limits might lead to wars.
These limits are hard to enforce.
Less population might be bad for the economy.
Small populations can still have high carbon emissions.
