Answer
Is the effect when the carbon dioxide (CO2), water vapor and other gases block the heat radiated from the earth at night.
The excess of CO2 makes an unbalance trapping too much energy in the earth.
Some effects are melting of glaciers, global temperature increase and sea level increase.
Can be combat reducing the production of CO2, reducing the consume of energy and planting trees.
Work Step by Step
The greenhouse effect is when the carbon dioxide (CO2), water vapor and other gases (Methane and nitrogen oxides) block the heat radiated from the earth at night and keep it warm.
The excess of CO2 makes an unbalance trapping too much energy in the earth wich causes rise of temperature and climatic change.
Some of the greenhouse effect are melting of glaciers, global temperature increase, sea level increase, etc.
This problem can be combat reducing the production of CO2, it means reducing the consume of energy (electric energy for example) and planting trees.
