But now, just as shale gas prices are finally rebounding from last year’s all-time-lows, the United States’ two biggest shale gas deposits are producing record amounts of fuel, threatening to push gas prices back down. As the Appalachian Marcellus shale basin and the Texas-based Permian basin rush to conquer a market share, the U.S. gas glut shows no signs of stopping.

Methane emissions influence but do not undermine the environmental case for gas. If the industry can build on the progress to date and deliver a clearer picture on the level of emissions and actions to address them, the arguments for gas displacing coal in power generation and oil products in transport become much stronger.

The climate consensus now has two derogation levels for those who disagree. Climate ‘contrarians’ like Bjørn Lomborg disagree about mitigation policies. Climate ‘deniers’ like Judith Curry disagree about the underlying climatology

The IPCC carbon budget concludes that changes in atmospheric CO2 are driven by fossil fuel emissions on a year by year basis. A testable implication of the validity of this carbon budget is that changes in atmospheric CO2 should be correlated with fossil fuel emissions at an annual time scale net of long term trends. A test of this relationship with insitu CO2 data from Mauna Loa 1958-2016 and flask CO2 data from twenty three stations around the world 1967-2015 is presented. The test fails to show that annual changes in atmospheric CO2 levels can be attributed to annual emissions.
