This new and more accurate estimate means that replacing coal with natural gas doesn't do as much to reduce climate change as it should.
Gas prices usually rise heading into long weekends. The reasons behind wild oil price fluctuations, reflected at the pumps, is about a lot more than economics.

Oil prices have little to do with supply or demand or even economic forces. Instead, it's all about politics.
Two separate studies have concluded that fracking was the likely cause of a fault line rupture, precipitating the 5.5 earthquake.
Earthquakes can shape political decisions so understanding them is crucial.

Many Coloradans feel powerless to protect themselves from pollution and other fallout caused by the state's fracking boom.
Coal seam gas extraction has increased social stress in Darling Downs.
University of Queensland
Research into Queensland's Darling Downs area has found social stress caused by housing pressure, population shifts and the 'two-speed economy' of coal seam gas.

Governments and energy firms will find it hard to generate the necessary public acceptance for such a controversial technology.
A new report finds concerns about water infrastructure tops the list for Canada’s water providers.
World Water Day shines a light on the importance of safe, clean drinking water, but a new report finds Canada's freshwater systems are under stress.

Shale gas exploitation in the US has helped cut is greenhouse gas emissions by 11%. A study explores what would happen if this were expanded globally, and the findings challenge conventional wisdom.
New research shows the size of man-made earthquakes is linked to how deep industry wastewater is injected into the ground.

The French president said he would eliminate all coal-fired plants in his country by 2021, while his US counterpart is pushing policies intended to make them more profitable. Either way, the laws of economics will win.
There are concerns about the negative environmental and social impact of fracking in the Karoo.
It is extremely important to monitor local seismic activity before fracking starts to avoid causing harm.
Drilling for water in the Karoo where one major concern from fracking is that groundwater will be affected in the shale gas extraction process.
A vulnerability map could help assess the risks associated with fracking and groundwater which around 300 towns depend on in South Africa's Karoo.

As global demand for energy and mineral supplies increases worldwide, the number of man‑made earthquakes is expected to rise. That increases the importance of understanding connection between the two.
Fracking has led to an increase in truck traffic, one of the reasons for worsening trends on air quality in areas with oil and gas drilling.

The fracking boom has led to a large increase of hydrocarbon emissions in rural areas, reversing some regional air toxics trends.
With all parties backing the fracking ban apart from the Tories, Scotland will have to secure full devolvement for energy if it is to fully realise its ambitions for renewables
There are indications shale gas may be present in South Africa’s Karoo.
South Africa's Karoo region potentially holds shale gas that could transform the energy economy of the country. But given the uncertainties around exploration what's the next logical step?
