• by causing it to rain more often
• by melting glaciers and ice caps
• by increasing the number of undersea volcanic eruptions
• by creating bigger and more powerful hurricanes

Why does cutting down trees increase global warming?

• trees soak up carbon dioxide
• trees provide shade which counteracts global warming
• trees absorbs the sun's energy without radiating back into the atmosphere
• trees drain greenhouse gases like methane from soil

What happens to the temperature if more greenhouse gases are released into the atmosphere?

• Temperature goes up
• Temperature goes down

Things you can do to help decrease global warming include:

• Eat more ice cream.
• Keep your freezer door open.
• Keep your air conditioner on high.
• Turn off your lights when you’re not using them.
