Atmospheric Greenhouse Gas Concentrations European Environment Agency The enhanced greenhouse effect What has scientists concerned now is that over the past 250 years, humans have been artificially raising the concentration of greenhouse gases in the atmosphere at an everincreasing rate, mostly by burning fossil fuels, but also from cutting down carbonabsorbing forestsAdding more greenhouse gases decreases the amount of infrared radiation energy leaving the atmosphere To get the energy back in balance, the surface of the Earth has to warm up, so that it will emit more infrared energy, some of which will leave the atmosphere and compensate for the effect of the added greenhouse gases Of greenhouse gases in the atmosphere
