The Science **The greenhouse effect comes from over 100 years of accepted proven science. There is no other theory for what keeps our planets temps warm and stable. It is about 30 deg c hotter than without it. **CO2 is a greenhouse gas with known measurable radiative properties and its concentration in the atmosphere, as well as all the other gases and their properties are also known. **It is measured by satellite that the energy entering the planet is more than leaving, by the first law of thermodynamics this means that energy within the planet is increasing. **By the laws of physics this can take on many forms but cannot diminish. It is a planet, there are many places it can go, the atmosphere is but 5%, including land, oceans and melting ice. **Measurements from satellite tells us that over time the fall in energy is coming from the same radiation bands as that utilised by CO2. **Measurements from the surface show an increase in energy from the same bands. **The lower stratosphere has cooled consistent with less upwelling radiation as measured by the previous 2 statements. **CO2 as a greenhouse gas absorbs and reradiates the CO2 coming up from the surface in all directions, thereby slowing down the loss of radiation, consistent with all off the above. **We have increased CO2 since industrialisation by 40%. **In the last 100 or so years temperatures have increased by about 0.8 deg c (depending on global data set, some more, some less but all around the same ballpark).
