Researchers have reviewed nearly 400 scientific articles related to sea level rise and associated risks and concluded that most studies may have underestimated global sea level rise by an average of 0.3 meters. In some areas of the Global South, these levels could be up to 1 meter higher than previously thought. According to the authors, a reassessment of the methodology used to characterize the impact of sea level rise is necessary, as this could have implications for policy, climate finance, and coastal adaptation plans. The study is published in Nature.

The Atlantic Ocean's main current system - the AMOC - could weaken without collapsing this century, according to modeling published in Nature. This finding contradicts earlier studies that predicted the collapse of the AMOC around 2050. The research uses models that include extreme changes in greenhouse gas concentrations and freshwater levels in the North Atlantic. This system of ocean currents is involved in regulating global temperatures.
