The first amendment, the London Amendment of 1990, required the complete phaseout of CFCs, halons, and carbon tetrachloride by the year 2000 in developed countries and by 2010 in developing countries. The 2018 World Meteorological Organization (WMO) scientific assessment of ozone depletion showed that the ozone layer had a chance to recover to pre-1980 levels by 2060 thanks to the Montreal Protocol banning ozone depleting chemical emissions. Excessive exposure to such radiation commonly results in the development of skin cancers; in 2012, a . 6016, 1985, pp. Will Trump Ratify It?

The effect of the Kyoto Protocol on global warming So, why did the Montreal Protocol succeed where other environmental initiatives failed? The Montreal Protocol is widely considered as the most successful environment protection agreement. Cannon explained the ocean absorbs a large amount of carbon dioxide. Another big reason the Montreal Protocol worked was because of the public support generated by scientists-turned-advocates.

Despite initial backlash, Rowland and Molinas research was validated more than a decade later, when British scientists discovered a hole in the ozone layer above Antarctica in 1985. President Ronald Reagan Ozone, together with ordinary molecular oxygen (O2), is able to absorb the major part of the suns ultraviolet radiation and therefore prevent this dangerous radiation from reaching the surface, according to the Royal Swedish Academy of Sciences. The hole that scientists discovered was more of a thinning layer, where concentrations of ozone, or O3, are low. Photochemical & Photobiological Sciences, vol. The importance of the Montreal Protocol in protecting climate How the world already prevented far worse warming this century The United States has been a leader within the Protocol throughout its existence, and has taken strong domestic action to phase out the production and consumption of ODS such as chlorofluorocarbons (CFCs) and halons.

Felix Pretis, a statistician at the University of Oxford in the UK, cautioned that the Montreal Protocol alone can't account for the full magnitude of reduced warming seen since 1998. Greenhouse gases like CO2 are prevalent in huge sectors of national economies, like transportation, manufacturing, energy and infrastructure. Saving the ozone layer drastically reduced climate change effects The protocol also has advisory bodies known as Assessment Panels that are responsible for issuing regular reports on phasing out progress and assessing alternatives to ODSs. HFCs are widely used alternatives to ODS such as hydrochlorofluorocarbons (HCFCs) and chlorofluorocarbons (CFCs), which are already controlled under the Protocol. This publication and its impacts eventually led to the Nobel Prize in Chemistry for Rowland and Molina, although worldwide support was slow-coming. U.S. Environmental Protection Agency, 2017.
