Global Warming

• During photosynthesis, trees absorb large amounts of CO2 from the atmosphere
• Deforestation causes an increase in the CO2 concentration in the atmosphere, as less CO2 is removed from the atmosphere
• If deforestation occurs by means of the burning of trees or if felled trees are left to rot, large quantities of carbon are released into the atmosphere as CO2. This leads to a further increase in CO2 concentration in atmosphere
• This increase in CO2 concentration leads to an enhanced greenhouse effect, resulting in global warming and climate change
• A tree canopy provides shade by day and retains heat by night. These effects are removed in deforestation and organisms are exposed to more extreme temperatures
