Earth System Sciences

Earth System Sciences (ESS) investigates the integrated components of our planet—atmosphere, hydrosphere, cryosphere, lithosphere and biosphere—and the physical, chemical and biological processes that link them. Through a combination of in situ observations, satellite remote sensing, laboratory analysis and numerical modelling, ESS seeks to quantify energy and mass exchanges, reconstruct past climate variability and predict future environmental change. Emphasis falls on global-scale circulations, biogeochemical cycles of carbon, nitrogen and water, land–ocean–atmosphere feedbacks and human impacts on natural systems. By uniting disciplines such as meteorology, oceanography, geology and ecology, ESS provides a holistic framework for understanding extreme events, sea-level rise, ecosystem resilience and the consequences of greenhouse-gas emissions. Its insights underpin adaptation strategies, guide resource management and inform policy measures aimed at sustaining planetary habitability in the face of accelerating anthropogenic pressures.

New findings have clarified the atmospheric drivers behind the prolonged warming of surface waters in the Northeast Pacific. Analysis shows that extratropical wave trains, triggered by moisture anomalies over the Mediterranean and North Atlantic, propagate across the jet stream and reinforce the atmospheric ridge responsible for ‘warm blobs’, offering improved predictability for marine heatwave events and their downstream influence on North American climate extremes. Another study highlights the role of mountainous topography in modulating El Niño-Southern Oscillation impacts on western United States precipitation. By isolating topographic and long-term trend influences, researchers demonstrate that high-elevation zones in the Intermountain West experience up to six times greater ENSO-induced variability than adjacent lowlands, with implications for water-resource planning under changing climate regimes.

Advances in satellite-based ocean monitoring have yielded a 42-year global sea surface temperature record (1980–2021) at 0.05° resolution, combining data from twenty infrared and two microwave radiometers. By correcting for differing observation times and sensor biases, this gap-free dataset delivers daily analyses with quantified uncertainties, enhancing the detection of long-term warming trends, marine heatwaves and model-data intercomparisons. In the Arctic, an optimally interpolated daily sea-and-sea-ice surface temperature dataset (1982–2021) has been validated against drifting buoys, moored platforms and airborne sensors. Results reveal an average Arctic surface warming of approximately 4.5 °C over four decades, with regional maxima approaching 10 °C in sectors of the Barents Sea, underscoring the urgency of polar climate adaptation and ecosystem risk assessments.

Technical terms

Earth System Science (ESS): The interdisciplinary study of Earth’s major subsystems (atmosphere, hydrosphere, cryosphere, lithosphere and biosphere) and their interactions.

Teleconnection: A climate linkage whereby anomalies in one region (e.g. sea-surface temperature) influence remote atmospheric circulation patterns.

Sea Surface Temperature (SST): The temperature of the ocean’s uppermost layer, retrieved by satellite radiometers or in situ measurements, crucial for weather and climate studies.

Marine heatwave: An extended period of anomalously high sea surface temperatures with ecological and economic impacts.

Optimal interpolation: A statistical gap-filling method that combines observations with background fields to generate complete spatial analyses.

ENSO (El Niño–Southern Oscillation): A coupled ocean-atmosphere phenomenon in the tropical Pacific that affects global weather and hydroclimate variability.
