Before we drown we may die of thirst
The island nation of Kiribati is one of the world's most vulnerable to rising sea levels. But residents may have to leave well before the ocean claims their homes.
Decrease in CO2 efflux from northern hardwater lakes with increasing atmospheric warming
Boreal lakes are biogeochemical hotspots that alter carbon fluxes by sequestering particulate organic carbon in sediments1, 2 and by oxidizing terrestrial dissolved organic matter to carbon dioxide (CO2) or methane through microbial processes3, 4. At…
Cultural geography II: Cultures of nature (and technology)
Recent cultural geographic research, located at a variety of settings (laboratory, clinic, battlefield, container port), has emphasized culture’s productive dimensions through studies of the linked construction of nature, culture, and technologies.…
Biogeography of Mediterranean Hotspot
Biodiversity Re-Evaluating the 'Tertiary
Relict' Hypothesis of Macaronesian Laurel
Forests
The Macaronesian laurel forests (MLF) are dominated by trees with a laurophyll habit comparable to evergreen humid forests which were scattered across Europe and the Mediterranean in the Paleogene and Neogene. Therefore, MLF are traditionally…
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'…
Greenland supraglacial lake drainages triggered by hydrologically induced basal slip
A dense network of GPS observations shows that rapid lake drainage events on the western Greenland Ice Sheet are preceded by period of ice-sheet uplift and/or enhanced basal slip.
Agricultural policy: Govern our soils
Luca Montanarella calls for a voluntary international agreement to protect the ground beneath our feet from erosion and degradation.
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…
Timing and climate forcing of volcanic eruptions for the past 2,500 years
Ice-core and tree-ring data show that large volcanic eruptions in the tropics and high latitudes were primary drivers of temperature variability in the Northern Hemisphere during the past 2,500 years, firmly implicating such eruptions as catalysts in…
The benefits of traditional knowledge
A study of two Balkan ethnic groups living in close proximity finds that traditional knowledge about local plant resources helps communities to cope with periods of famine, and can promote the conservation of biodiversity.
Global exchange and accumulation of non-native plants
A global database of alien plants, showing that over 13,000 species, nearly 4% of the global flora, have become naturalized in a new location.
The formation and fate of internal waves in the South China Sea
Internal oceanic waves are subsurface gravity waves that can be enormous and travel thousands of kilometres before breaking but they are difficult to study; here observations of such waves in the South China Sea reveal their formation mechanism,…
Erosion of organic carbon in the Arctic as a geological carbon dioxide sink
Robert G. Hilton, Valier Galy, Jérôme Gaillardet, Mathieu Dellinger, Charlotte Bryant, Matt O'Regan, Darren R. Gröcke, Helen Coxall, Julien Bouchez & Damien Calmels
Fundamentals of Physical Geography, 2nd Edition
The Fundamentals of Physical Geography (2nd Edition) online textbook describes an area of knowledge within Geography known as Physical Geography. The textbook contains over three hundred pages of information and more than four hundred 2-D…
The multi-millennial Antarctic commitment to future sea-level rise
Despite computational and methodological uncertainties, and a wide range of potential greenhouse gas emissions, here millennial-scale simulations of the Antarctic Ice Sheet in a warming climate show that most of Antarctica’s fringing ice shelves will…
The changing form of Antarctic biodiversity
Antarctic biodiversity is much more extensive, ecologically diverse and biogeographically structured than previously thought. Understanding of how this diversity is distributed in marine and terrestrial systems, the mechanisms underlying its spatial…
