According to TFA: Likely candidates include venting from oil and gas activities, which are primarily coalbed methane exploration and extraction in this region; active coal mines; and natural gas seeps... The Four Corners coal-fired power plant, near Farmington, is one of the targets Nasa wants to investigate as a possible cause of the methane

The Last Time Oceans Got This Acidic This Fast, 96% of Marine Life Went Extinct 417

merbs writes: The biggest extinction event in planetary history was driven by the rapid acidification of our oceans, a new study concludes (abstract). So much carbon was released into the atmosphere, and the oceans absorbed so much of it so quickly, that marine life simply died off, from the bottom of the food chain up. That doesn't bode well for the present, given the similarly disturbing rate that our seas are acidifying right now. A team led by University of Edinburgh researchers collected rocks in the United Arab Emirates that were on the seafloor hundreds of millions of years ago, and used the boron isotopes found within to model the changing levels of acidification in our prehistoric oceans. They now believe that a series of gigantic volcanic eruptions in the Siberian Trap spewed a great fountain of carbon into the atmosphere over a period of tens of thousands of years. This was the first phase of the extinction event, in which terrestrial life began to die out.

Coal bed methane, that is in the cracks and pores of coals, is old, old and well known thing.

Yeah. It's even mentioned in TFA:

This indicates the methane emissions should not be attributed to fracking but instead to leaks in natural gas production and processing equipment in New Mexico's San Juan Basin, which is the most active coalbed methane production area in the country.

'The results are indicative that emissions from established fossil fuel harvesting techniques are greater than inventoried,' Kort said.


Experts: Aim of 2 Degrees Climate Goal Insufficient 442

An anonymous reader points out that a long held goal of keeping the Earth's average temperature from rising above 2 degrees Celsius might not be good enough. "A long-held benchmark for limiting global warming is 'utterly inadequate,' a leading U.N. climate scientist declared. Keeping the Earth's average temperature from rising past 2 degrees Celsius – a cap established by studies in the early 1970s – is far too loose a goal, Petra Tschakert, a professor at Penn State University and a lead author of an assessment report for the U.N.'s Intergovernmental Panel on Climate Change, or IPCC, said in a commentary published in the journal Climate Change Responses. Already, with an average increase of just 0.8 degrees Celsius, she wrote, 'negative impacts' are 'widespread across the globe.' Tschakert called for lowering the warming target to 1.5 degrees Celsius."

The Heartland institute is paid by the fossil fuel industry to spread misinformation about climate change. Popular misinformation sites like WUWT have received $80,000 in a single year. Even as a lowly intern you can get a small piece of the pie. They'll pay you $150/week to comment on relevant blogs, newspaper articles, and social media.

SecState (667211) writes "Hundreds of full-time, well-paid trolls operate thousands of fake accounts to fill social media sites and comments threads with pro-Kremlin propaganda. A St. Petersburg blogger spent two months working 12-hour shifts in a "troll factory," targeting forums of Russian municipal websites. In an interview, he describes how he worked in teams with two other trolls to create false "debates" about Russian and international politics, with pro-Putin views always scoring the winning point. Of course, with the U.S. government invoking "state secrets" to dismiss a defamation case against the supposedly independent advocacy group United Against a Nuclear Iran, Americans also need to be asking how far is too far when it comes to masked government propaganda."

Layzej (1976930) writes ""Founder of Greenpeace" Patrick Moore, who was reported here last week denying the physics of anthropogenic climate change on behalf of the Heartland Institute, is now claiming that the pesticide glysophate is safe for Argentinians to drink. "You can drink a whole quart of it and it won't hurt you" he stated. "It is not dangerous to humans". Although when pressed he refused to take a sip, he did state "I know it wouldn't hurt me"."

Yup. That's about the level of 'argument' presented by Patrick Moore. It basically amounts to just making stuff up. Here is the temperature increase over the last 18 and 26 years according to the satellite reconstruction compiled by skeptic Roy Spencer: . The warming over the period is considerable. Equivalent to billions of nuclear bombs worth of accumulated energy.

He shows he hasn't read an IPCC report when he says IPCC will "consider only the human causes of global warming". IPCC outlines scientific consensus on all sources of climate change from solar cycles to milankovitch cycles.

Honestly, there's a whole chapter on it. He could have figured this just by reading the headers.
