Drinking water from fracking waste? Almost sounds too good to be true, right? Or perhaps more like a headline from The Onion? Researchers are now proposing a very questionable solution to freshwater scarcity in the water-poor regions of the world â€” simply take the extremely toxic wastewater produced by hydraulic fracturing and put it through an imperfect purification/desalination process. Mmmm. S ... Read More

2) Why is it important?
This news story highlights important challenges facing Vene ... Read More
Kenya is expected to receive lower-than-normal and poorly distributed rains in the last quarter of 2013 which could impact agricultural production and power supply from hydro-electric dams, the Meteorological Department said on Friday. East Africa's biggest economy relies heavily on agriculture and power from dams. Analysts watch the forecasts to gauge the impact on inflation, which could be push ... Read More
As we've previously written, researchers now know that cities obey some fascinating scaling relationships. The larger they grow in population, the more patents, infrastructure, crime and economic output cities produce, each according to its own exponential equation. When a city doubles in size, for instance, it more than doubles its GDP. ... Read More
One of the most controversial issues emerging from the recent Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report (AR5) is the failure of global climate models to predict a hiatus in warming of global surface temperatures since 1998. Several ideas have been put forward to explain this hiatus, including what the IPCC refers to as 'unpredictable climate variability' that is ass ... Read More
A new study looking at the impacts of climate change on the world's ocean systems concludes that by the year 2100, about 98 percent of the oceans will be affected by acidification, warming temperatures, low oxygen, or lack of biological productivity â€“ and most areas will be stricken by a multitude of these stressors.

While only about 30% of Californiaâ€™s usable water storage capacity lies at higher elevations, high-elevation hydropower units generate on average 74% of Californiaâ€™s in-state hydroelectricity. In general, high-elevation plants have small man-made reservoirs and rely mainly on snowpack. Their low built-in storage capacity is a concern with regard to climate warming. Snowmelt is expected to shift t ... Read More
