Official representatives from all over the world agreed to a climate deal in Vienna that will eliminate 0.5 degrees of temperature warming by the end of the century.
As the Montreal Protocol from 1987 showed its first positive results over the ozone layer, the 2016 Vienna climate deal could be decisive for greenhouse gas emissions.
The event’s purpose was to amend the Montreal Protocol, which focused on the chlorofluorocarbons (CFCs) that were destroying the ozone layer. While the atmospheric cover showed the first signs of recovery, the officials will make a second move towards reducing hydrofluorocarbons (HFCs).
The chlorofluorocarbons are organic compounds that contain chlorine, fluorine, and carbon, and they were usually used in aerosol cans and air conditioners. The scientists discovered during the ‘70s that the CFCs that were released into the atmosphere were attacking the ozone layer.
The Montreal Protocol had been signed by all UN and EU nations and involved taking immediate measure to stop the use of CFCs.
However, the manufacturer started to replace the chlorofluorocarbons with hydrofluorocarbons and by this, they created a new problem.
The hydrofluorocarbons are indeed ozone friendly. They also have proven to be efficient in refrigerants. The only thing that could not have been foreseen is the fact that the HFC is a powerful greenhouse gas and by this, it also contributes to climate change.
The international officials have met again to add HFC limits to the previous protocol signed in the ‘70s.
The results of the limitations would be a reduction of 0.5 degrees Celsius in the forecasted warming trend that will affect our planet by the end of this century.
Before the Paris climate agreement, the experts forecasted a warming of 4.5 degrees Celsius in the next 80 years. Climate scientists explain that a 2 degrees increase will create significant environmental changes, and some say that changes will appear with as little as a 1.5 degrees increase.
The scientists say that, even if a 0.5 degrees Celsius cover a large part of the issue, it will not remove the risks of climate change. The general opinion is that the Vienna deal against HFCs is only a small step towards improvement, and the most necessary measures that need to be taken have to go in the direction of CO2.
Even limiting the HFCs will not be as easy as it may seem, as it will have an important impact on the economies of small and developing nations. The demands for cooling technology will increase as the climate will continue to warm, and the manufacturers will have a hard time finding a suitable industrial replacement.
The participating countries have now to decide the rate of implementing this commitment to reduce the HFCs. India proposed a 15 years grace period for smaller countries, the Island States asked for a slower reduction rate, but an agreement has yet to be reached.
