How can planting of trees help reduce climate change?
absorb carbon dioxide from the air in photosynthesis
What do you think killed about 35,000 people in Europe in 2003 due to increased temperatures?
Heat waves
Topography
Higher altitudes have cooler temperatures mountain ranges affect rainfall patterns
Carbon Footprint
