Ground Report | New Delhi: 267 crore people in danger; Around 267 million people around the world are at risk due to rising sea levels. That is, these people live in those low-lying areas of the world, which are less than 2 meters above sea level. Not only this, scientists estimate that by the end of the century this figure will increase to 41 crores.
267 crore people in danger due to rising sea level
Most of these people live in tropical regions. The paper, published in Nature Communications, finds that 267 million people worldwide live on land less than 2 metres above sea level.
Scientists have measured those places with the help of NASA satellites which are located less than 2 meters above sea level. Along with this, they have also used one of the most advanced techniques of remote sensing, a method called LIDAR, which uses laser rays to measure altitude on the Earth’s surface.
According to research, about 6.49 lakh square kilometers of this area, or that is to say, about 62 percent of the area is in tropical areas. A large part of which is at an altitude of less than a meter above sea level. It is estimated that about 72 percent of the population at risk of future water level rise will be living in tropical regions, of which 59 percent will be in tropical regions of Asia alone.
Due to climate change, sea level increased
Scientists believe that due to climate change, the sea level has increased significantly than before, as well as it is also causing frequent severe storms. This has increased the risk of flooding in the coastal areas.
The biggest impact of this will be on countries like Indonesia, Bangladesh, and India in Asia. About 118,200 square kilometers of Indonesia will be about 2 meters below sea level, which is about 6.3 percent of its total area. However, according to scientists, this does not mean that Europe and America will escape their danger.
Last year, a survey published by Climate and Atmospheric Science, which collected the views of 106 experts, suggested that coastal cities should prepare for rising sea levels that could reach 5 meters by 2300, which It can engulf the homes of hundreds of millions of people. people
Maarten van Aalst, Professor in Climate and Disaster Resilience, and a contributing lead author to the Intergovernmental Panel on Climate Change (IPCC) said: “These numbers are another wake-up call about the vast number of people at risk at lower levels of risk. Regions, particularly vulnerable countries in the global south, are often experiencing these exposures as part of a toxic mix with other risk factors, including COVID-19.
