[ndlr] Un article de la revue Nature revoit à la hausse l’impact de la montée de la mer sur les côtes et le risque de submersion de plusieurs grandes villes d’Asie. Dans cette perspective à horizon 2050, une grande partie du delta du Mékong disparaitrait sous les eaux. L’urgence climatique n’est pas un vain mot.

Southern Vietnam could all but disappear.
The first map shows earlier expectations of submerged land by 2050. But the new outlook, the second map, indicates that the bottom part of the country will be underwater at high tide.
More than 20 million people in Vietnam, almost one-quarter of the population, live on land that will be inundated.
Much of Ho Chi Minh City, the nation’s economic center, would disappear with it, according to the research, which was produced by Climate Central, a science organization based in New Jersey, and published in the journal Nature Communications. The projections don’t account for future population growth or land lost to coastal erosion.
