The lives of 300 million people in coastal areas could be threatened by sea level rise by 2050, estimates a study released yesterday, which points to Asia as the most vulnerable region.
According to the study, published in the journal Nature Communications, more than 200 million people at risk live in China, Bangladesh, India, Vietnam, Indonesia and Thailand.
In their work, scientists corrected existing coastal zone relief data using an artificial intelligence algorithm.
"The predictions of rising sea levels have not changed, but as we use new data, we have identified many more people living in vulnerable regions than we thought," said study author and Climate Central chairman Ben. Strauss, quoted by the AFP news agency.
According to the authors of the investigation, data provided by the US space agency NASA, which has mapped 95% of Earth's surface, may have margins of error.
Since 2006, water levels have risen by an average of about four millimeters per year, a figure that could be multiplied by 100 if greenhouse gas emissions remain unchanged, according to a report released in September by the Intergovernmental Panel on Climate Change. Climate Change, which integrates UN members.
If the rise in global temperature is limited to 2 ° C above the pre-industrial age average as foreseen by the 2015 Paris Agreement on Climate Change, sea levels will rise by about 50 centimeters by 2100. However, if emissions If pollutants continue at their current rate, the rise in water could be almost twice as significant.
