Climate Denial's Death Knell: 97 Percent of Peer-Reviewed Science Confirms Manmade Global Warming, Consensus Overwhelming

A new survey conducted by a team of volunteers at Skeptical Science has definitively confirmed the scientific consensus in climate science literature - 97 percent of peer-reviewed papers agree that global warming is happening and human activities are responsible.  

It does not get any clearer than this. It should finally put to rest the claims of climate deniers that there is a scientific debate about global warming. Of course, this bunch isn't known for being reasonable or susceptible to facts. But maybe the mainstream media outlets that have given deniers a megaphone will finally stop. 

The peer-reviewed survey, Quantifying the consensus on anthropogenic global warming in the scientific literature, was published today in the peer-reviewed Environmental Research Letters, a publication of the Institute of Physics (IOP).

The citizen science team looked at some 12,000 peer-reviewed climate science papers and found a 97% consensus that humans are causing global warming. The work expanded upon an earlier survey of the literature by Naomi Oreskes, published in 2004, as well as an informal review conducted by James Powell, published on DeSmogBlog in November 2012

Lead author John Cook created a short video summarizing the findings of the new survey:

BC LNG Exports Blow Climate Targets Way, Way Out of the Water

Rendering of BC LNG export facility in BC.

This post is the second of a two part series. Read the first installment, Unreported Emissions From Natural Gas Blow Up BC's Climate Action Plan.

Methane leaks from British Columbia's natural gas industry are likely at least 7 times greater than official numbers increasing the entire provinces' carbon footprint by nearly 25%. That's like putting 3 million more vehicles on BC's roads.

As Part One revealed official government figures state only 0.3% to 0.4% of BC's natural gas production leaks into the atmosphere. No believes that is accurate. Independent studies in the US show these methane leaks range between 2% and 9%.

All aspects of natural gas operations including drilling gathering, processing and pipelines can leak methane into the atmosphere. The industry doesn't like to call them leaks, preferring the term “fugitive emissions.”

Seals, valves, joints, compressor pumps all can leak. There are literally hundreds of thousands of points where this can occur said Bill Tubbs Manager, Environmental Permitting & Regulation at Spectra Energy Transmission. Headquartered in Houston, Texas Spectra is the biggest gas pipeline and processing companies operating in western Canada.

We don't measure fugitive emissions, we estimate how much for reporting purposes,” Tubbs told DeSmog.

Fox Snooze: Global Warming Name Game Debunked By Media Matters (Again)

Media Matters put out a video this past week with clips of all the recent FOX News mentions of a global warming name conspiracy. The Fox 'conspiracy' is that 'liberals' stopped calling it global warming and started calling it climate change. Little did they realize, apparently, that the man responsible for the partisan polarization over the terminology of climate change vs. global warming is none other than FOX News contributor Frank Luntz. Watch: 


As Media Matters points out: 
Scientists use “global warming” when speaking about the increase in average global surface temperatures. They use “climate change” to refer to all the other disruptions that greenhouse gas emissions are causing – from rising sea levels, to abruptly changing precipitation patterns that increase the likelihood of droughtsand wildfires in certain areas and extreme flooding in others, to acidifying oceans that disturb the marine food web.

Koch & Exxon-funded Willie Soon Challenged by Students at Climate Denial Event

Crossposted from PolluterWatch.

Rarely do we meet those who have made careers selling us lies. Consider the oddball doctors who took tobacco money to deny a link between cigarette smoking and cancer, or the handful of scientists who take oil and coal money to discredit global warming science, or the people who have done both.

Last week, students in Wisconsin and Michigan stepped up to such an opportunity when CFACT Campus, the student arm of a well-known cabal of fossil fuel apologists, hosted climate change denier Willie Soon at several campus events around the country.
