Changes in India's monsoon rainfall could bring serious consequences to more than a billion people

Global warming is increasing the variability of India’s monsoon rains faster than previously projected, according to a recent study from the Potsdam Institute for Climate Impact Research (PIK).

For every degree Celsius of global warming, monsoon rainfalls will likely increase by 5%, according to one of the key points of the analysis.
While more rain might seem like a good thing, too much (or too little) can harm crops. India depends on this seasonal rainfall to help sustain the crops necessary to feed the second-most populated country in the world. 하나, the authors suggest climate change will negatively effect their agriculture if left unabated.

    It’s not just an increase in monsoon rainfall this study suggests could be impactfulit is the variability.
      This includes more prolonged dry spells where rainfall is needed most.

        A more “혼란스러운” 과 “이상한 사람” future lies ahead

        India’s agriculture sector encompasses nearly 20% of its annual GDP and plays acrucial rolein the countries well-being, 보고서에 따르면. If climate change is left unchecked, residents should expect more “혼란스러운” monsoon seasons, which could negatively impact farming, according to climate scientist Anders Levermann, one of the lead authors of the study.
          쌀, 예를 들면, a major source of sustenance across the Indian subcontinent, is highly susceptible to changes in rainfall. Crops need the precipitation, especially during the initial growing period. 그러나 too little or too much at once can harm the plants.

          This is called climate variability and its unpredictability is what has experts concerned.
          The problem with increased variability is, 하나, the reduced predictability, which makes it harder for farmers to deal with the monsoon,” Levermann, who is affiliated with the Potsdam Institute, tells CNN.
          Like clockwork, every June thru September, farmers throughout India anticipate the beginning and end of the yearly rains, also known as the Southwest Monsoon. Frequently during this period, reports of flooding inundate international news outlets as heavy precipitation falls erratically, overwhelming the flood management systems in place.

          농업 policy exper Devinder Sharma told CNN that farming practices will need to adapt to this climate variability, but exactly how remains unknown.
          We don’t know how climate change will work out. It could be heavy rain at one point, followed by drought or cyclones. It won’t be uniform. This will create a lot of problems for the agriculture sector and as well as for the economy.

          History underlines humans influence on rainfall intensification

          수요일 study from PIK confirms that human behavior, such as the burning of fossil fuels, is a major contributor of heat trapping greenhouse gases, even overtaking the slow natural changes seen across thousands of years.
            Under unabated climate change, the CO2 effect is by far the strongest effect and will dominate the change in monsoon over all natural and other human-made effects,” says Levermann.
            Despite reductions in pollution levels during worldwide 코로나 19 봉쇄, heat-trapping greenhouse gases continue to surge to new record highs.
