Successful regulation of greenhouse gas emissions requires knowledge of current methane emission sources. Existing state regulations in California and Massachusetts require ∼15% greenhouse gas emissions reductions from current levels by 2020. However, government estimates for total US methane emissions may be biased by 50%, and estimates of individual source sectors are even more uncertain. This study uses atmospheric methane observations to reduce this level of uncertainty. We find greenhouse gas emissions from agriculture and fossil fuel extraction and processing (i.e., oil and/or natural gas) are likely a factor of two or greater than cited in existing studies. Effective national and state greenhouse gas reduction strategies may be difficult to develop without appropriate estimates of methane emissions from these source sectors.
The implications of unconventional drilling for natural gas: a global public health concern
11 Oct 2013
This commentary explores the need for research to quantify the potential risks to the environment and to human health from unconventional natural gas development in both the short-term and long-term.

The Environmental Price Tag on a Ton of Mountaintop Removal Coal
Brian D. Lutz, Emily S. Bernhardt, William H. Schlesinger
This study provides an estimate for how much coal is produced per unit landscape disturbance in the Central Appalachians using regional satellite-derived mine delineations and historical county-level coal production data for the period 1985–2005.
Histopathological Analysis of Fish from Acorn Fork Creek, Kentucky, Exposed to Hydraulic Fracturing Fluid Releases

Diana M. Papoulias and Anthony L. Velasco
The objective of this study was to describe post-fracking water quality in Acorn Fork and evaluate if the changes in water quality could have extirpated Blackside Dace populations.
