a new study It shows that super Hurricanes (the strongest form of tropical storms) may have a more devastating impact on the people of South Asia in the coming years The international study, led by the University of Bristol, conducted an in-depth study of the super hurricane amphan in 2020.
The research results were published in the journal climate resilience and sustainability of the Royal Meteorological Society on May 8, 2022. The research results show that if greenhouse gas emissions continue at the current rate, the tsunami height caused by the super hurricane will be 1 meter higher than that of "anpan", and 2.5 times the Indian population will be affected.
"South Asia is one of the most climate sensitive regions in the world. In historical cases, super hurricanes have killed tens of thousands to hundreds of thousands of people. Although the Intergovernmental Panel on climate change emphasizes that South Asia is such an important region, there are few studies on the climate impact of South Asia," said Dan Mitchell, a professor of climate science and lead author at the University of Bristol.
Mitchell continued: "this study, in collaboration with local scientists, provides much-needed climate impact information in one of the most vulnerable regions in the world. It provides important evidence to support the reduction of greenhouse gas emissions to achieve the climate goals of the Paris Agreement, while other evidence tends to focus on high-income countries with less impact and easier adaptation".
Although the impact on Bangladesh will be moderate, the risk will also increase by 60% to 70%. But this will lead to the reduction of coastal population in the future. Encouragingly, the research team continues to show that if the climate target of the Paris Agreement is 2 degrees Celsius higher than the pre industrial level, the risk of flooding to the population there will be reduced to close to zero.
Professor of hydrology, Bangladesh University of engineering and Technology (buet) "The latest IPCC report mentions that there will be more intense tropical cyclones in the future. This study shows that under the high emission scenario, the impact of extreme storm surge floods (greater than 3 meters) caused by strong cyclones on the population of Bangladesh and India will increase by 200% in the future. Therefore, strong, rapid and sustained greenhouse gas emission reduction is very important for the realization of the Paris Agreement," said Saiful Islam, a special author of the study And reducing losses and damage in highly vulnerable countries such as Bangladesh.
