My, my, if it is not dumbass Sis spewing her usual retarded logic. Sure, I can show the science. Can state it, also. It is called the absorbtion spectra of GHGs, water vapor, carbon dioxide, methane, nitious oxides, and various manmade chemicals that have no natural analog.
The fact that there had to be something in the atmosphere that is capturing some of the reflected heat was first observed by Joseph Fourier in the 1822. Tyndall demonstrated the absorbtion of the infrared by the various GHGs in 1858. And Arrnhenius did the first real quantification of the effects in 1896.
And we have added 40% more CO2 to the atmosphere since 1850. And 150% more CH4.
Of course, do not take my word for it. Here is the information from the site of the American Institute of Physics, a scientific society made up of scientific societies.
The Carbon Dioxide Greenhouse Effect
Now Sis, we all know that you are so much smarter than all the Phd physicists that make up this Scientific Society. Not only smarter than any of them, but all of them put together. You and that obese drugged out radio jock.
