Subidas e descidas do nível médio do mar no passado mais rápidas do que se pensava
More disturbingly, the record suggests that sea level can rise or fall as fast as two meters a century—nearly 12 times as fast as sea level rise in the past 100 years and indicating the potential for a meter of sea-level rise within one human lifetime. “This has major implications for future concerns with sea-level change,” says geoscientist Jeffrey Dorale of the University of Iowa, lead author of the new research published in the February 12 issue of Science. “Our study indicates rapid rates of ice melting and ice formation. The mechanisms underlying these dramatic changes need further consideration as we look to a future of impending climate changes.”
