Global warming mean increment in the temperature of earth's atmosphere due to green house gases and pollutants like CO,Methane,CFC etc. global warming is a burning issue for the mankind. in this article we will know about the role of methane in global warming
what is methane - Methane is a colourless, odourless gas chemically known as CH4, it is formed naturally from the degradation of organic wastes and is also produced by humans.
concern about methane -
- Methane is currently 260% higher than the pre-industrial era.
- Man-made methane is responsible for 45% of global warming.
- Methane can cause 80% more global warming than carbon -di-oxide
- Methane emissions see biggest increase in 2021
Global steps to reduce methane's emission
- GMP(global methane pledge): GMP was announced in 2021 at COP26. Its goal is to reduce global methane emissions by 2030 by at least 30 percent below 2020 levels.
- Methane Alert and Response System (MARS): It was presented at COP27 to track methane emissions. With its help, the source of methane can be traced.
- MethaneSat: MethaneSat is a state-of-the-art satellite. It is designed to accurately trace global methane emissions.
Major sources of methane - (per year)
- wetlands - (161.6 million tons)
- Fossil fuels - (129.5 million tones)
- livestock - (103 million tons)
- Paddy farming(34.2 million tons)
