  • The exact timing and magnitude of past changes in Atlantic Ocean circulation, and its relation to abrupt climate changes remains elusive. Here, the authors show a spatially coherent picture of western Atlantic circulation changes, which reveals a two-step AMOC slowdown at the beginning of the deglacial period.

  • The role ice sheets play in the silica cycle over glacial−interglacial timescales remains unclear. Here, based on the measurement of silica isotopes in Greenland meltwater and a nearby marine sediment core, the authors suggest expanding ice sheets considerably increased isotopically light silica in the oceans.

  • Permafrost peatlands are thawing, yet the timing and spatial dynamics of thaw are not well constrained. Under moderate and high warming scenarios, permafrost peatlands in Europe and Western Siberia will cross a tipping point where the climate becomes unsuitable, putting their carbon stores at risk.
