As per recent studies, a 3 degree Celsius increase in global warming would cause droughts to last more than a year in 90% of the Himalayan Region. According to research that was published in the journal Climatic Change, adhering to the Paris Agreement's temperature targets of 1.5 degrees Celsius global warming rather than 3 degrees Celsius warming can prevent 80% of the increased human exposure to heat stress in India.

National Risks Associated with Climate Change

The UK's University of East Anglia (UEA) scholars headed the team that measured the national rise in climate change hazards to both humans and the environment with increasing global temperature. The dangers of drought, flooding, drops in crop yields, loss of biodiversity, and depletion of natural capital are all significantly increased with each degree of global warming, according to a collection of eight research, all of which concentrate on India, Brazil, China, Egypt, Ethiopia, and Ghana.

Agricultural Land Drought Condition

More than 50% of the agricultural area in each of the countries under study is expected to be subjected to severe droughts lasting more than a year during a 30-year period, according to the team's findings, which show very high increases in the exposure of agricultural land to drought with 3 degrees Celsius warming, restricting the rate of global warming to 1.5 degrees Celsius.

Effect on India's biodiversity and pollination

It was discovered that in India, pollination decreases by half at 3–4 degrees Celsius, whereas it decreases by 25% at 1.5 degrees. Half of the nation can serve as a safeguard for biodiversity if warming is kept to 1.5 degrees Celsius, compared to 6% at 3 degrees, according to the study.

Sea level rise and economic damages

The economic costs of rising sea levels are expected to climb in coastal countries, but at a slower rate if global warming is kept to 1.5 degrees Celsius, according to their projections.

Request for Action

The scientists cautioned that additional work is required to slow down global warming because the existing global policies are expected to cause a temperature of three degrees Celsius.
