Second Cause of Global Warming

Chlorofluorocarbons were introduced to the world in the 1920s and are used in a range of industrial, commercial, and residential uses and is a big part of Global Warming. Chlorofluorocarbons, along with others like chlorine- and bromine-containing compounds, have been implicated in the boost of reduction of ozone in our planet’s stratosphere. This stuff is non-flammable, non-toxic, and non-reactive with other chemical composites. These nice safety characteristics make them useful as coolants in air conditioners and refrigerators, propellants for aerosol sprays, and blowing agents. Production and use of Chlorofluorocarbons increased as a demand by us humans for production of these common products.
It was not until 1973 that chlorine was found to be a catalytic agent in ozone devastation. Catalytic obliteration of ozone gets rid of the odd O2 species while leaving chlorine unchanged. We knew that this was potentially damaging to the ozone layer, but beyond question evidence of stratospheric ozone depletion was not exposed until 1984. An intricate situation of atmospheric dynamics, chemical reactions, and solar radiation, was found to explain the abnormal low levels of ozone during the polar springtime. Current missions to the Arctic areas show that related processes can occur in the northern hemisphere, but to a lesser level due to warmer temperatures. We as a nation have to do something soon before this climate change takes a real toll on our planet!


  1. Although not every scientist worldwide may look at global warming in the same way, they do overwhelmingly agree that the Earth’s atmosphere is getting warmer. Worldwide temperatures have risen more than 1°F (0.6°C) over the past century, and 17 of the past 20 years have been the hottest ever recorded.

  2. Thanks to share informative blog . Hurricane damage is often seen as result of Global warming means warm seawater and the heating of oceans coincides with a recent spike in hurricane activity .Hurricane Sandy was the most destructive natural disaster in United States.
