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 that nighttime urban heat-island intensity nearly doubles when heatwaves coincide with pronounced soil-moisture deficits. We examine the implications of this amplification for heat early-warning systems and for the strategic siting of urban green infrastructure.

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 char…

Climate adaptation finance is expanding rapidly, yet its allocation frequently diverges from where vulnerability is most acute. We analyse adaptation funding flows across thirty countries to assess the alignment between allocation criteria…

Rainfall-triggered landslides pose an escalating threat to mountain communities as extreme precipitation intensifies. We integrate a multi-decadal inventory of slope failures with statistically downscaled rainfall projections to map evolvin…
