With an effort to fix the ozone hole over Antarctica, more than two dozen countries replaced chloroflourocarbons in refrigerators, air conditioners and hair spray in 1989. But do you know, using other chlorine or fluorine containing gases also contributes hugely towards global warming?
But, it is obvious and practical that the CFC-using countries would tend to find the cheapest alternative available. And thus, though the chemicals that replaced CFCs are better for the ozone layer, they do little to help global warming! These chemicals also trap heat like any other greenhouse gas, acting as one of the atmosphere’s reflective layer.
With this finding, this consequence now haunts the nations that signed both the U.N. treaties!
