The timing of emissions reductions, even more so than the rate of reduction, will be key to avoiding catastrophic thresholds for ice-melt and sea-level rise, according to a new Cornell study.
The timing of emissions reductions, even more so than the rate of reduction, will be key to avoiding catastrophic thresholds for ice-melt and sea-level rise, according to a new Cornell study.
The study, published Oct. 10 in Nature Climate Change, models the impacts of different emissions trajectories, finding that emissions and uncertainties around ice sheet dynamics will have the most impact on sea-level rise through 2200.
“Roughly speaking, we found that somewhere between 2065 and 2075, emissions really start to become the dominant factor, as well as uncertainties related to emissions like Antarctic Ice Sheet tipping points,” said Vivek Srikrishnan, assistant professor of biological and environmental engineering in the College of Agriculture and Life Sciences. “As we get to 2060, 2065, the mitigation we do today will start to really materially impact the range of sea-level rise outcomes.”
