The increase of carbon dioxide in the atmosphere creates a greenhouse effect.
To explain this usually some sunlight is reflected back into space while some is absorbed by the earth keeping the planet warm. However the increase in greenhouse gases such as carbon dioxide prevent the light from reflecting back into space and this light becomes trapped causing the earth to heat more then it should. You can almost think of the trapped heat from the greenhouse gases as a blanket around the earth trapping the heat in.
Answer: The relationship between the Earth, moon, and sun during a solar and Lunar eclipse is Lunar eclipses only happen once the Moon is in the opposite direction of the Sun in the sky, a montly occurence, which is known as a full moon.
