When did we realize there were greenhouse gases?

    In 1824 a man named Joseph Fourier used several previous scientific discoveries to compose his hypothesis that light travels more easily through gases to the earth than it is able to leave through gases in the form of heat. However scientists did not know precisely which atmospheric substance was causing the absorption or “greenhouse” effect. By 1861 it was noted that CO2 could be causing the effect and in 1895 scientist Svante Arhennius predicted the global warming effect on glacial melting and other environmental factors which would take place in the near future. Today, we know these studies are accurate and have labeled the problem “greenhouse gases.”
