The invisible carbon dioxide (CO2) blanket is getting thicker
The invisible blanket of carbon dioxide as a result of greenhouse gaz emissions is getting thicker leading to an increase in global temperatures across the planet. As billion tons of unseen carbon dioxide are piling up into the already tainted atmosphere it blocks the longer wave lengths of heat that normally bounce back from the earth. This invisible blanket is acting like as a giant greenhouse leading to an increase in the global temperature, which in turn is depleting our very limited water resources.
The current global temperature has already exceeded 1.09 degrees Celsius above the normal. According to the recent IPCC report, under the intermediate, high and very high greenhouse gas emissions scenarios considered the global warming of 1.5°C relative to 1850–1900 would be exceeded during this century.
Such increase in temperatures is negatively impacting our vital resources that we depend on such as water resources.
Although water is a renewable resource, its supply is not inexhaustible. It is unlikely that sufficient new water resources will be found to meet the projected increase in demand exacerbated by climate change, as existing water resources are already under pressure, with the withdrawal of last resources.
Although not with the same amplitude but previous implementation of the 1987 Montreal Protocol is working due to a constant decline in the use of chemicals (Chlorofluorocarbons), known as CFCs. These chemicals were commonly used in aerosol cans and cooling systems, in the 1930’s onward. They were found later on to be at the origin of the ozone layer depletion, in 1974. The Montreal Protocol to reduce the use of these man-made chlorofluorocarbons (CFCs) was adopted in Montreal on 16 September 1987. It was ratified by 197 countries to enter into force on 26 August 1989. It is now considered as a landmark environmental success.
“Science was helpful in showing the path, diplomats and countries and industry were incredibly able in charting a pathway out of these molecules, and now we’ve actually seen the planet starting to get better. It’s a wonderful thing.” Susan Solomon/Jennifer Chu — MIT News Office
This recovery of ozone atmospheric protective layer is setting up a positive precedent in addressing also the rise in Earth’s temperature due to greenhouse gas (GHGs) emissions. The Montreal Protocol’s success of tackling the depletion of the ozone layer can help to tackle climate change by reducing further climate-warming.
