Global warming is undoing decades of progress made protecting marine reserves

Science
April 24 (UPI) -- For decades, conservationists have relied on marine reserves, protections that limit human activities like fishing across portions of the ocean, to increase biodiversity and fish biomass. In addition to protecting vulnerable ecosystems, marine reserves have helped scientists study the best strategies for conserving marine species and their habitats. But new research suggests marine preserves and their protective abilities are wilting under the pressure of rising global temperatures and repeated coral bleaching events, erasing decades of progress. "Climate change is so fundamentally changing the structure and composition of coral reef ecosystems, that the way the ecosystem functions and responds to common management and conservation approaches needs to be carefully re-ev...
Fracking: UK shale reserves may be smaller than previously estimated

Fracking: UK shale reserves may be smaller than previously estimated

Science
Previous projections of the potential amount of shale gas under the UK may have been significantly overestimated, according to a new study.Instead of 50 years of gas at the current rate of consumption, this new research suggests there are just 5-7 years' supply. But the UK's fracking industry, which represents companies like Cuadrilla, dismissed the report. The said the sample size was too small to draw serious conclusions.The recovery of shale gas through hydraulic fracturing or fracking has been a slow moving and controversial affair in the UK over the past decade. Attempts by oil and gas companies to drill wells and extract gas have been held up by planning issues, concerns about earth tremors and public displays of disaffecti...
Arctic permafrost home to large mercury reserves, study finds

Arctic permafrost home to large mercury reserves, study finds

Science
Feb. 5 (UPI) -- Scientists have discovered large mercury reserves trapped in Arctic permafrost.According to a new study published in the journal Geophysical Research Letters, the mercury reserves are the largest in the world."This discovery is a game-changer," lead study author Paul Schuster, a hydrologist at the U.S. Geological Survey in Boulder, Colorado, said in a news release. "We've quantified a pool of mercury that had not been done previously, and the results have profound implications for better understanding the global mercury cycle."The monumental mercury levels were revealed by permafrost cores drilled in northern Alaska. Analysis suggests the Arctic permafrost holds double the amount of Mercury found in all the rest of the planet's ocean, sediment and atmospheric systems combin...
Fracking: Shale rock professor says UK gas reserves 'hyped'

Fracking: Shale rock professor says UK gas reserves 'hyped'

Science
The gas reserves in shale rocks in the UK have been "hyped", an academic said. Professor John Underhill from Heriot-Watt University said the UK's potential shale deposits were likely to have been disrupted by shifts in the earth 55 million years ago.He said the government would be wise to formulate a Plan B to fracking for future gas supplies.But the fracking firm Cuadrilla said it would determine how much gas was present from its test drilling.Hydraulic fracturing, or fracking, is a technique designed to recover gas and oil from shale, a sedimentary rock found worldwide.The amount of shale gas available in the UK is acknowledged to be a great unknown.Cuadrilla said estimates from the British Geological Survey (BGS) indicated a large potential gas reserve.What is fracking and why is it con...
