Physical Geography and Environmental Geoscience

Physical geography and environmental geoscience encompass the study of Earth’s surface and the dynamic interactions among its spheres—the lithosphere, hydrosphere, atmosphere and biosphere. Investigations range from the chemical weathering of rocks that shapes landscapes and regulates the global carbon cycle, to the physical forces driving mountain erosion, coastal change and tsunami inundation. Researchers combine field observations, laboratory experiments, remote sensing and numerical models to quantify rates of erosion, sediment transport, fluid flow and biogeochemical cycling. Such work underpins our understanding of natural hazards, resource distribution, ecosystem resilience and the long-term feedbacks that stabilise Earth’s climate. By integrating multiple disciplines—from geomorphology and geochemistry to climatology and hazard science—physical geography informs land-use planning, disaster preparedness and nature-based solutions that seek to harmonise human activity with the processes that have sculpted our planet.

Research from Nature Portfolio

A global compilation of catchment data demonstrates a remarkably consistent temperature control on silicate weathering intensity: feldspar dissolution rates rise monotonically with mean annual temperature between 0 °C and 30 °C. This finding refines climate–weathering feedbacks and supports kinetic models that regulate long-term carbon dioxide drawdown. Complementary work on river alkalinity reveals a nonlinear response to warming: low-emission scenarios may reduce mid-latitude carbonate alkalinity fluxes, whereas high-emission pathways could boost them by up to 68 %, with implications for ocean carbon uptake. In a distinct application, synthetic hydrodynamic proxies derived from high-resolution wave simulations have been combined with machine-learning frameworks to predict building damage in real time following large tsunamis. These proxies—encoding water velocity, debris impact and shielding effects—enable rapid, interpretable vulnerability assessments to guide relief efforts and resilience planning.

Technical terms

Silicate weathering: Chemical breakdown of silicate minerals by acidic waters, consuming CO₂ and releasing dissolved cations that influence global carbon budgets.

Carbonate alkalinity: The concentration of bicarbonate and carbonate ions in water derived from mineral dissolution, which buffers acidity and affects oceanic CO₂ uptake.

Hydrodynamic proxy: A synthetic variable from fluid-dynamics simulations representing complex forcings—such as tsunami velocity or debris impact—used to assess vulnerability rapidly.

Oxide nanolite: Nanometre-scale oxide crystals that crystallise swiftly in silicic magmas, extracting iron from melt and causing abrupt increases in viscosity that promote explosive eruptions.

Process chain: A sequence of coupled geomorphic events—often initiated by glacier retreat or permafrost thaw—where one hazard triggers another, extending impacts downstream.
