A new study by Australian scientists projects that the world will likely warm between 2 and 6 degrees Celsius (3.6 to 10.8 degrees Fahrenheit) from pre-industrial levels by 2100. The study published in Nature Climate Change finds that exceeding the 2-degree threshold is very likely under business-as-usual emissions scenarios even as scientists have long warned that passing the 2-degree mark would ... read more >>
Government and foreign aid are interlocked when addressing the water crisis in East Africa. This region has 187 km3 of renewable freshwater resources per year, yet governments and organizations are in a crusade against the odds to provide water to its inhabitants. Although the Millenium Development Goal (MDG) to increase water access was reached on a global level last year, in East Africa the cha ... read more >>
The Colorado River, recently named America’s most endangered river, supports millions of people in the American Southwest and northwest Mexico and helps irrigate millions of acres of land. It is shared by seven states in the U.S. and Mexico, through a complex series of legal agreements and treaties. ... read more >>
Groundwater depletion in the United States has accelerated over the last decade, according to the U.S. Geological Survey, contributing to both localized problems and global issues, like sea level rise. ... read more >>
Isolating the causes of extreme variations or changes in the hydroclimate is difficult due to the complexities of the driving mechanisms, but it is crucial for effective natural resource management. In Australia's Murray-Darling Basin (MDB), ocean-atmosphere processes causing hydroclimatic variations occur on time scales from days to centuries, all are important, and none are likely to act in iso ... read more >>
Fierce competition for water could trigger conflict unless nations cooperate to share the diminishing resource, leaders from Asia-Pacific nations warned on Monday.
From Central to Southeast Asia, regional efforts to secure water have sparked tensions between neighbours reliant on rivers to sustain booming populations.
Breakneck urbanisation, climate change and surging demand from agricult ... read more >>
Hydrogeologic investigations over the past 20 years have largely confirmed the concepts developed by peatland ecologists that stress the close linkage between hydrology and peatland ecology. However, these studies have also shown how groundwater flow systems interacting with the climate, geology, and biota of large peat basins largely shape the ecological development of these waterlogged ecosyste ... read more >>
Sea-level rises could send floods driven by storm surges over London's Thames Barrier regularly by the end of the century, if nothing is done to bolster the UK's flood defences, scientists warned on Tuesday. But around the world sea level rises from melting ice alone are likely to be "in the tens of centimetres" rather than several metres by 2100, as some outlying estimates had predicted, accordi ... read more >>
Climate change is affecting the snow blanket in the Northern hemisphere, which in terms affect the habitat of plants, animals, and microbes that depend on ice to stay warm during cold winter months. ... read more >>
The Earth’s northern polar region will be almost ice-free in the warmest months by 2050, sooner than previously estimated, according to a study by two federal government scientists who work on climate change. ... read more >>
