Global Warming and Carbon Cycle

Why does cutting down trees increase global warming?

• trees soak up carbon dioxide and removing them causes more carbon to stay in the atmosphere

• 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
