Global study of more than 23,000 marine mollusk species projects major shifts in body size by 2100 — including surprising growth in some animals and ocean regions

The Southern Ocean is one of Earth's most important climate regulators, yet the clouds covering this remote region remain among the least understood features in atmospheric science. Their influence on the planet's energy balance makes accurate cloud representation essential for reliable weather forecasts and climate projections. A new study combines observations from an Antarctic expedition with advanced atmospheric datasets and climate models to investigate the processes behind this long-standing challenge in climate science.

A new, international, community-led scientific review warns that major gaps in knowledge along Antarctica’s coast are now one of the biggest obstacles to reliably predicting future global sea level rise.

Coastal residents may be worried about exposure to forever chemicals from sea spray during hot summer months, but York University researchers found there was little evidence of per- and polyfluoroalkyl substances (PFAS) contamination from marine aerosols, a finding that surprised them. The study looked specifically at areas impacted by sea spray from the Atlantic Ocean generated by waves breaking on the coast of Newfoundland and Labrador, however, despite its windy, marine location they found it was not an issue as previously thought.
