Russian Arctic warming leads to major ice loss

Glaciers and ice caps in two archipelagos in the Russian Arctic are losing enough meltwater to fill nearly five million Olympic-size swimming pools each year, research shows.

Tiny organisms shed big light on ocean nutrients

As the world warms, sweeping changes in marine nutrients seem like an expected consequence of increased ocean temperatures. However, the reality is more complicated. New research suggests that processes below the ocean surface ...

Scientists get to the bottom of deep Pacific ventilation

Recent findings, with important implications for ocean biogeochemistry and climate science, have been published by Nature Communications in a paper by Associate Professor Mark Holzer from UNSW Science's School of Mathematics ...

Studies add to concern about climate tipping

Two model studies document the probability of climate tipping in Earth subsystems. The findings support the urgency of restricting CO2 emissions as abrupt climate changes might be less predictable and more widespread in the ...

Antarctic Circumpolar Current flows more rapidly in warm phases

Earth's strongest ocean current, which circulates around Antarctica, plays a major role in determining the transport of heat, salt and nutrients in the ocean. An international research team led by the Alfred Wegener Institute ...

Human-driven climate change only half the picture for krill

In the heart of their Antarctic habitat, krill populations are projected to decline about 30% this century due to widespread negative effects from human-driven climate change. However, these effects on this small but significant ...
