By 2100, rising seas worldwide could inundate areas where 153 million people now live if carbon emissions continue unchecked and ice sheets melt at the high end of estimates, according to projections by a group of nine climate scientists. Asian countries are the most threatened, with 30 million people in China at risk of displacement, followed by nearly 13 million in Vietnam. Figures are based on current population in affected areas and could change due to population growth or outmigration from flood-prone regions.
