Climate change does not occur uniformly around the world: instead, in a process called polar amplification, the Arctic warms more rapidly than the tropics or mid-latitudes. Recent work published in Nature suggested that upper-atmospheric transport processes accounted for much of the recent polar amplification, but this conclusion proved controversial.

As tree habitats shift towards the poles in response to climate change, we must study the neglected, trailing edges of forests, warns Csaba M

Hydrogen fuel-cell vehicles, largely forgotten as attention turned to biofuels and batteries, are staging a comeback. Jeff Tollefson investigates.

Arguments over which type of farming will best meet growing food demands are ignoring the most critical factor - water availability - say analysts from the International Water Management Institute (IWMI).

The veil of official secrecy that has shrouded talks on an

Many species are experiencing sustained environmental change mainly due to human activities. The unusual rate and extent of anthropogenic alterations of the environment may exceed the capacity of developmental, genetic, and demographic mechanisms that populations have evolved to deal with environmental change.

India, like the rest of the world, is experiencing an epidemic of diabetes, a chronic disease characterized by dangerous levels of sugar in the blood that cause cardiovascular and kidney disease, which lower life expectancy. The prevalence of diabetes (the proportion of the population with diabetes) has been increasing steadily in India over recent decades, particularly in urban areas.

The scale and nature of pre-Columbian human impacts in Amazonia are currently hotly debated. Whereas pre-Columbian people dramatically changed the distribution and abundance of species and habitats in some parts of Amazonia, their impact in other parts is less clear.

Remote sensing has long been a useful tool in global applications, since it provides physically-based, worldwide, and consistent spatial information. This paper discusses the potential of using these techniques in the research field of water management, particularly for

Without exception, global warming affects the water resources in Korea. Several climate change projects have been initiated for future water resources assessment but have produced very different projections with a significant range of heterogeneities. Therefore, it is necessary to develop a standard procedure and scheme that can reduce this heterogeneity.
