CFC Ban Offers Time to Save the Environment

The Montreal trend of banning chemicals like chlorofluorocarbons (CFC)  as they cause Depletion of the Ozone Layer has become a global thing now. Without the settlement, the environment would have been exposed to the Sun’s ultraviolet (UV) radiation far faster.

General Kofi Annan, Former UN Secretary, has called it possibly the sole most effective international settlement.

Tortured plants

According to the international team of scientists, increased and persistent use of chlorofluorocarbons (CFC) would have made contributions to global air temperatures elevation by an extra 2.5°C by the end this century. Fraction of that might have been attributed to CFCs that are also probable greenhouse gases.

But the damage caused to Ozone layer might also have released extra carbon dioxide into the environment. Dr. Paul Young, the lead researcher said that in earlier experiments, we have exposed plants to high UV radiations. He further added that they get very undersized and becomes unable to absorb the carbon dioxide in the surrounding.

The scientists projected there would be:

  • 580 billion tonnes reduced carbon stowed in soils, vegetation and forests
  • an extra 40-50% of CO2 in the air

Dr. Young said that what they see in their world-avoided experiment is an extra 2.5C warming over any warming that they would get from the rise of greenhouse-gas. But analogous group action to restrict the emissions of greenhouse-gas was anticipated to be very much challenging. He said that the science was being heard of and to act accordingly.
