Stand behind an air conditioner when it's running, Touch a light bulb when it's turned on. Put your hand on a motor when it's running. Now times that by 6.79 billion people. Have you ever flown over a city at night ? Just look at all the lights.Shoot... we even create heat trying to keep our food cold. Everything humans do creates heat. Population control is the only answer but when you have so many religious freaks sitting around patting each other on the back talking about how good they are when chances are that they have never helped a strainger out in their entire lives...well..... the earth will keep getting warmer. Populationj control is the only answer. CH4 and CO2 ? Ha.... I laugh in your face.

The earth will be a much healthier planet when the cockroaches take over.
