Answer:
Climate change is partly the result of an increased concentration of greenhouse gases, especially carbon dioxide
Step-by-step explanation:
Increased concentration of carbon dioxide, leads to change in temperature because it traps the heat in the Earth's atmosphere. For greenhouse, carbon dioxide is the main gas. The other green house gases are water vapor, carbon dioxide, methane, nitrous oxide and ozone. Absence of the greenhouse leads to the average temperature of about -18 degree Celsius. But when these gases are present the average temperature is about 15 degree Celsius.
