Global and Regional Ocean Mass Budget Closure Since 2003

Global and regional ocean mass budget closure since 2003

In recent sea level studies, discrepancies have arisen in ocean mass observations obtained from the Gravity Recovery and Climate Experiment and its successor, GRACE Follow-On, with GRACE estimates consistently appearing lower than density-corrected ocean volume observations since 2015. These disparities have raised concerns about potential systematic biases in sea-level observations, with significant implications for our understanding of this es…

Sea Level Rise Could Drive ‘Catastrophic’ Inland Migration Even if Warming Is Limited to 1.5°C, Study Says

While the Paris Agreement targets no more than 1.5 degrees Celsius of global warming compared to pre-industrial levels in order to curb the worst impacts of climate change, a new study warns that the amount of sea level rise that will come with that amount of warming could still lead to “catastrophic” inland migration. In the study, published in Communications Earth and Environment, scientists analyzed data from previous warm periods on Earth, a…
