Here’s how harmful gas from fracking can contribute to climate change

Published

on

One of the justifications for fracking is the use of natural gas as a bridging fuel between coal and a low-carbon future. However natural gas is mostly methane, which has strong global warming impacts in its own right. Natural gas therefore only provides climate benefits over coal if the leakage is no more than 2-3%.

We cannot measure leaks from every pipe joint. One alternative is to measure the sum of lots of leaks from a distance. Flights over US shale gas fields reveal large methane sources, but these areas also have cattle farms that produce methane and the two sources need to be separated.

Shale gas also contains ethane, which does not come from farming. Looking at ethane and methane together, shale gas and oil extraction were found to be easily the dominant source giving leak rates of 0.18-2.8% even before the gas was distributed to users. Some active drilling areas were notable super-emitters.

Ethane from shale gas and oil extraction is bringing its own problems . Ozone, synonymous with Los Angeles smog , is a normally a summer pollutant, but in Utah, high levels have been measured in winter for the first time. Here leaked ethane built up in cold, still air and interacted with low-angle sunlight.

Ethane can remain in the air for around two months, making it a global pollutant. Ethane measured from the top of the Swiss Alps has been rising since the start of large scale US shale gas extraction in 2009, indicating an increase in the global methane leakage from natural gas.

This move comes after a judge ruled that the original defamation suit can move forward.

Dershowitz has denied all allegations from Guiffre, arguing that evidence proves he did not even know the people that Guiffre is alleging are witnesses at the time.

Gen. Barry McCaffrey ridicules childish ‘Home Alone’ Trump over his ‘comical’ letter to Turkey’s president

Published

Appearing on MSNBC on Saturday morning, retired General Barry McCaffrey came to the defense of former Donald Trump cabinet member Gen. James Mattis while taking a jab at the president for acting like an unattended child when dealing with world leaders.

Speaking with host Jonathan Capehart, the former official in President Bill Clinton's administration said the president was out of line attacking Mattis as "overrated" and said it could come back to hurt the president because the retired general is held in high esteem within military circles.

Addressing the president's antics, McCaffery showed he doesn't think much of the current Commander in Chief.

Published

Donald Trump kicked off his Saturday morning on Twitter with a simple attempt to promote the hashtag #StopTheCoup but didn't get many backers.

But he did get a lot of derision and explanations about what a "coup" really is -- along with inspiring the hashtag: #ThePresidentIsACrybaby.

As one commenter noted, "Holding the president* accountable for his actions isn't a coup... it's their job. "

That was the general response, see below:
