Pacific western boundary currents and their roles in climate
A review of western boundary currents in the Pacific Ocean explores their far-reaching influence on the El Niño/Southern Oscillation, the Indonesian Throughflow, Asian monsoons, and ocean circulation in the South China Sea, and concludes that major…
Plate tectonics on the Earth triggered by plume-induced subduction initiation
Scientific theories of how subduction and plate tectonics began on Earth—and what the tectonic structure of Earth was before this—remain enigmatic and contentious1. Understanding viable scenarios for the onset of subduction and plate tectonics2, 3 is…

Policy and Geopolitics: Bounding Europe in EUrope
This article analyzes geopolitics as a bureaucratic practice conducted by career policy professionals. Empirically, I investigate how the European Neighbourhood Policy (ENP) continuously produces and transforms the geopolitical category of 'Europe'…
Political geography - political geographies of globalization III: resistance
The article examines the political geographies of globalization of resistance. The author also explores the role of romance as an alternative tragic elements in less comforting reexaminations of resistance. In connection, he mentions about the study…
Political geography II:
Islands and archipelagos
This second of two progress reports on the subdiscipline of political geography explores islands and archipelagos as material sites and political concepts with which to understand spatial ontologies of power. The piece reviews thematic interests in…
Potential sea-level rise from Antarctic ice-sheet instability constrained by observations
Large parts of the Antarctic ice sheet lying on bedrock below sea level may be vulnerable to marine-ice-sheet instability (MISI)1, a self-sustaining retreat of the grounding line triggered by oceanic or atmospheric changes. There is growing…
Precise interpolar phasing of abrupt climate change during the last ice age
A new ice core from West Antarctica shows that, during the last ice age, abrupt Northern Hemisphere climate variations were followed two centuries later by a response in Antarctica, suggesting an oceanic propagation of the climate signal to the…
Rarity in mass extinctions and the future of ecosystems
The fossil record provides striking case studies of biodiversity loss and global ecosystem upheaval. Because of this, many studies have sought to assess the magnitude of the current biodiversity crisis relative to past crises—a task greatly…
Recovery potential of the world's coral reef fishes
Continuing degradation of coral reef ecosystems has generated substantial interest in how management can support reef resilience1, 2. Fishing is the primary source of diminished reef function globally3, 4, 5, leading to widespread calls for…
Recovery potential of the world's coral reef fishes
A study of the recovery potential of over 800 of the world's coral reefs shows that 83% of fished reefs are missing more than half their expected biomass, with severe consequences for key ecosystem functions; protection from fishing would allow full…
Seismic evidence of effects of water on melt transport in the Lau back-arc mantle
Tomographically derived seismic velocities are used to infer the distribution of partial melt below the Lau Basin, revealing an unexpected relationship between the amount of in situ melt and the water content of the magma, indicating that subducted…
Soil biodiversity and human health
Soil biodiversity sustains human health and its loss can be mitigated by sustainable management.
Soil biodiversity and soil community composition determine ecosystem multifunctionality
An article about how soil diversity and soil community composition determine ecosystem multifunctionality
