What does the green curve mean? Till what time do the red and the green curve go together? What does the yellow curve mean? What is the conclusion of this research? What does the model tell us?

greenhouse The world is becoming hotter.That it is so because of the greenhouse effect. It works like this: sunlight gives us heat. Some of the heat warms the atmosphere, and some of the heat goes back into space.

The greenhouse effect Sunlight (1) gives the heat to the greenhouse. It warms the greenhouse. The heat can not go back into atmosphere, because there is a special glass in greenhouses.
