The Southern Ocean sustains some of the most extensive and least understood cloud cover on Earth, and persistent model biases in this region limit confidence in climate projections. Using in-situ measurements from a research cruise, we characterise the influence of natural marine aerosols on cloud droplet number concentration and albedo. These observations help to explain long-standing radiative biases and better constrain the regional cloud radiative effect.

Compound hot and dry extremes are intensifying under climate change, yet their combined influence on urban thermal environments remains poorly characterised. Drawing on a dense municipal sensor network and atmospheric reanalysis, we show th…

Nutrient export from agricultural catchments varies sharply with hydrological state, complicating efforts to manage downstream water quality. Using high-frequency in-stream chemistry, we demonstrate that nitrate export is governed by the ac…

Tropical Andean glaciers are among the most climatically sensitive ice masses on Earth, yet observational constraints on their recent evolution remain limited. We integrate two decades of optical and synthetic-aperture radar observations to…
