There is always something of course – the weather is variable – but for 2023 and 2024 the residuals were higher than for any other year in decades. We find that ENSO had a negligible impact in 2023, but was a substantial contributor in 2024. More sophisticated modeling might well be able to reduce the uncertainty there.

As the Earth’s air and oceans warm, the ice sheet is starting to melt at an ever-faster rate. The Antarctic Ice Sheet has grounded ice, which is ice that sits on the solid Earth below it and ice shelves, which extend out from the grounded portion and float on the ocean surface. These are called marine basins.
