From what i have read this is global warming... Light from the sun, mostly made up of ultra violet light, having a short wave length hits earth and is absorbed by atoms making up the earth. That energy is then released as Infrared light (heat) having a longer wave length. When the infrared light is redirected back out to space it may hit green house gases. Such as CO2, H2O, methane, from what i know it is the molecules with three atoms that make up the g-house gases. So when the infrared light hits these three atom molecules they turn opaic and reflect the energy back down to earth. So if the atmosphere lets 70% of the infrared light threw then 30% will be kept from escaping. A good example of this is mars and venus. Mars atmosphere is thin and can have a day time temp of 60-70deg but at night it gets very cold. Venus atmosphere is so dense that light doesn't even hit the ground and stores all that energy making the ground on mars hot enough to melt lead. So global warming has probably been happening for a very long time if not since the dawn of time on earth. But with CO2 leaves hitting all time highs when do we start to worry. Also CO2 level fluctuate with the seasons go down with the spring and summer and up in the winter. ie summer plants grow and take in CO2 and don't during the winter. In global warming they call this the "breath of the earth" a sin curve over the period of a year. So GW is nothing new but NOW it is man made and when do we start to control IT... not have it control us??????
