John Wiley and Sons Inc. and the Royal Geographical Society (with IBG) announced today the launch of the Society’s first fully open access journal: Geo: Geography and Environment.
The American Geophysical Union (AGU) today announced that John Orcutt, a distinguished professor of Geophysics at the Scripps Institution of Oceanography and former president of AGU, will serve as the inaugural editor of its newest open access, peer-reviewed journal, Earth and Space Science.

Biodiversity, or the variety of life found in a particular habitat, responds to changing environmental forces such as habitat destruction or climate change, but the responses may not be noticeable until long after the forces first exerted their effects.
Mercury contamination of ocean fish is a serious global health issue, and a new analysis of published reports reveals that the concentration of mercury in yellowfin tuna caught near Hawai’i is increasing at a rate ≥ 3.8 % per year.
The wild tiger Panthera tigris is considered critically endangered, and it faces unprecedented threats, including habitat loss and fragmentation, depletion of prey, and continued illegal poaching for trade of tiger bones for traditional medicine and skins for ornamentation and collection.
Dust from soil erosion due to wind can affect human health, traffic, and, on a larger scale, climate. Investigators compared different models that quantify how the wind energy spreads over an herbaceous surface using data from the Sahel region of Africa, where estimates of dust emissions remain uncertain. They found that the modeling tools give results in reasonable agreement, indicating that vegetation can decrease the amount of dust emitted from soil erosion by 6% to 26% in mass compared with bare soil.
Leading industry expert in commodity derivatives publishes first book to deal comprehensively with the subject of Agricultural Finance
A small stone container found by archaeologists a half-century ago has now been recognized as further evidence of a Viking or Medieval Norse presence in Arctic Canada during the centuries around 1000 A.D.
Inundation of nitrogen into the atmosphere and terrestrial environments, through fossil fuel combustion and extensive fertilization, has risen tenfold since preindustrial times according to research published in Global Biogeochemical Cycles. Excess nitrogen can infiltrate water tables and can trigger extensive algal blooms that deplete aquatic environments of oxygen, among other damaging effects.
When people hear about the dangers of the ozone hole, they often think of sunburns and associated health risks, but new research shows that ozone depletion changes atmospheric and oceanic circulation with potentially devastating effects on weather in the Southern Hemisphere weather.
The Sudbury Basin located in Ontario, Canada is one of the largest known impact craters on Earth, as well as one of the oldest due to its formation more than 1.8 billion years ago. Researchers who took samples from the site and subjected them to a detailed geochemical analysis say that a comet may have hit the area to create the crater.
Surface ice on oceans and lakes can cause major problems, both onshore and offshore. Specifically, surface waves interacting with ice can create hazardous conditions for cargo ships, damage coastal structures, and carry important nutrients away from the shore.
Managing carbon flow into the atmosphere has been a central focus of efforts aimed at protecting the planet and addressing climate change. A new European Journal of Soil Science review proposes that we focus less on sequestering carbon to mitigate CO2 buildup and more on using wisely the energy it carries.
Life on the Antarctic sea floor is under threat from crabs that could invade the area thanks to favorable conditions as a result of global warming, researchers warn.
When the supersonic solar wind hits the Earth’s magnetic field, a powerful electrical connection occurs with Earth’s field, generating millions of amperes of current that drive the dazzling auroras. These so-called Birkeland currents connect the ionosphere to the magnetosphere and channel solar wind energy to Earth’s uppermost atmosphere. Solar storms release torrential blasts of solar wind that cause much stronger currents and can overload power grids and disrupt communications and navigation.
As soon as lava flows from a volcano, exposure to air and wind causes it to start to cool and harden. Rather than hardening evenly, the energy exchange tends to take place primarily at the surface. The cooling causes a crust to form on the outer edges of the lava flow, insulating the molten lava within. This hardened lava shell allows a lava flow to travel much further than it would otherwise, while cracks in the lava’s crust can cause it to draw up short.
There is no published account where hippopotamuses are demonstrably shown swimming or floating at the surface of any body of water. But if they can’t swim, how did they reach and colonize islands?
John Wiley and Sons Inc. announced today its selection by the Association for the Sciences of Limnology and Oceanography (ASLO) to publish their highly regarded portfolio of journals focused on marine and inland water systems.
Magnetic substorms, the disruptions in geomagnetic activity that cause brightening of aurora, may sometimes be driven by a different process than generally thought, a new study in the Journal of Geophysical Research: Space Physics shows.
A new Journal of Evolutionary Biology study provides evidence that physical barriers formed by oceans can influence language diversification.
In a world warmed by rising atmospheric greenhouse gas concentrations, precipitation patterns are going to change because of two factors: one, warmer air can hold more water; and two, changing atmospheric circulation patterns will shift where rain falls.
Researchers who analyzed the vulnerability of ecosystems to climate change have found that between 10 and 28% of the world’s terrestrial vegetated area can be considered refugia, depending on whether or not wilderness areas are considered. Refugia are areas of biological diversity where natural environmental conditions remain relatively constant during times of great environmental change.
