Rising Seas Could Threaten Three Times More People than Scientists Previously Believed

Ho Chi Minh City, along with the rest of southern Vietnam, “could all but disappear” by 2050.

Bangkok, Thailand, currently home to over eight million people, is under severe threat.

Basra, Iraq, the nation’s second-largest city, “could be mostly underwater” by mid-century.

“Rising seas could affect three times more people by 2050 than previously thought, according to new research, threatening to all but erase some of the world’s great coastal cities.

“The authors of a paper published Tuesday developed a more accurate way of calculating land elevation based on satellite readings, a standard way of estimating the effects of sea level rise over large areas, and found that the previous numbers were far too optimistic. The new research shows that some 150 million people are now living on land that will be below the high-tide line by mid century. Read more . . .

“For political leaders and business people, we think it is important for you to know that it is extremely unlikely that scientists are exaggerating the threat of the climate crisis. It is far more likely that things are worse than scientists have said. We have already seen that the impacts of increased greenhouse gases in the atmosphere are unfolding more rapidly than scientists predicted. There is a high likelihood that they will continue to do so, and that the IPCC estimates – that emissions must be rapidly reduced, if not entirely eliminated, by 2050 – may well be optimistic. The fact that this conclusion is hard to swallow does not make it untrue.” Read more . . .
