What is the cause effect and solution of the greenhouse effect?

Normal greenhouse effect:

1. The cause of the normal greenhouse effect is the greenhouse gases in the atmosphere that capture the sun's heat as it radiates back out from the earth.
2. The effect of the normal greenhouse effect is to keep the earth warm enough for life.
3. We do not need a solution for the normal greenhouse effect because it is not a problem for us.

1. The cause of the enhanced greenhouse effect is the extra greenhouse gases, mainly carbon dioxide and methane, that we have been adding to the atmosphere since the Industrial Revolution, mostly by burning coal, oil and natural gas. Deforestation means that less carbon dioxide is removed from the atmosphere.
2. The effect of the enhanced greenhouse effect is to make the atmosphere warmer, all over the world - global warming.
3. The solution for the enhanced greenhouse effect is for the whole world to use renewable energy sources for industry, transport and electricity, so we can stop burning fossil fuels. If the world plants more forests the trees will remove carbon dioxide from the atmosphere. If we improve our agricultural practices we can reduce the amount of methane put into the atmosphere.
