Update, June 29: This post has been updated to include a comment from Facebook.

Facebook is coming under fire again for aiding climate change deniers. The platform opened a fact-checking loophole that allows misinformation to spread widely, even with opposition from scientists.


CO2 Coalition, a non-profit with ties to the Trump administration and funded in part by climate-deniers Mercer and Koch, is at the forefront of the latest dispute, Newsweek reported.

The conservative group believes that climate change fears are overblown and that burning more fossil fuels will ultimately help the planet. They have increasingly used Facebook to reach a bigger audience, E&E News reported, and Executive Director Caleb Rossiter said that the current "battle" over climate-related posts serves as a microcosm in the overall "war" over how to reach an audience outside of conservative media.

"You can reach so many people both with your posts and your advertisements," Rossiter said in the news report. "We're kind of like Donald Trump. We're not happy with the treatment we're getting from the mainstream media, we resort to social media. That's where our action is in larger part."

While the most recent commotion was triggered by a viral column Rossiter wrote in the Washington Examiner, Facebook already had a complicated history with climate deniers and fact-checking.

In May 2018, Facebook founder and CEO Mark Zuckerberg hired a right-wing think tank known for climate misinformation to "figure out whether Facebook displays a liberal bias," Think Progress reported. In July of the same year, Zuckerberg took additional steps towards allowing misinformation on his platform, saying that "while he won't block fake news from appearing on his site, his fact-checkers would stop it from spreading widely," the news report said.

In a dilution of that "check-and-balance," Facebook hired fact-checkers with conservative biases and a history of climate misinformation in fall of 2017 and again in April 2019.

Climate scientists were encouraged when Facebook partnered with Science Feedback last year in an expansion of their third-party fact-checking program to bring in teams of Ph.D. climate scientists to verify the accuracy of content and to lessen the platform's role in driving viral misinformation, a Science Feedback release stated.

That optimism was short-lived.

In August 2019, five Science Feedback scientists reviewed a Washington Examiner column by CO2 Coalition's Rossiter and Patrick Michaels. The column, titled The great failure of the climate models, called climate models showing warming and increases in atmospheric carbon dioxide from fossil fuels "inaccurate," Newsweek reported.

All five scientists agreed that the piece "cherry-picks data and misleads readers" and tagged it as "biased" and "inaccurate" for Facebook. The piece was blocked from sharing as "false" and the coalition was prevented from running ads, reported E&E News.

Then came the loophole.

Facebook re-labeled Rossiter's piece as "opinion," allowing it to fall under a new fact-checking exception that overruled the climate scientists' "false" finding, reported E&E News. It became shareable, promotable with advertising and went viral.

The news report claimed a "conservative Facebook employee" can be credited with opening the door for the coalition and groups that attack mainstream climate science to leverage the "opinion" label to avoid fact-checking and spread misinformation.

CO2 Coalition, which requested the successful change, is celebrating the outcome. Rossiter noted to E&E News that after the "false" label was removed from his climate models piece, the coalition was allowed to buy ads again. They have since done so, with messages distorting climate change and claiming that they are "saving the people of the planet from the people who claim they are saving the planet." Those ads have received more than 50,000 impressions, Facebook data shows, as reported by E&E News.

The coalition and similar groups will look to Facebook to get their message to a larger audience because traditional news media "rarely seek comment on climate science from groups that reject consensus research," Rossiter said, the news report added.

Andrew Dessler, one of the five Science Feedback climate scientists who originally fact-checked CO2 Coalition's article, criticized Facebook and other social media for exempting "opinion" articles from even basic fact-checking.

"It's a powerful way to misinform people, since these groups can't win in the actual scientific arena, so they only can win in these media environments where they can pay to promote stuff," Dessler told E&E News. "It allows people to live in a bubble where you don't ever have to confront ideas that you don't want to deal with.

In response to a request for comment, a Facebook spokesperson told EcoWatch, "Our long-standing guidance to the independent fact-checkers has been that clear opinion content is not subject to fact-checking on Facebook; unsurprisingly, that includes opinion editorials." The spokesperson explained, " As our policy states clearly, if publishers want to dispute a fact-check rating, they are to do so directly with the fact-checker. Facebook's third-party fact-checkers can rate climate-related content; there has never been a prohibition on their doing so."

Additionally, Facebook posted a company blog Thursday titled Providing People With Additional Context About Content They Share. A "context" button, first created in 2018, "provides information about the sources of articles in News Feed," the blog said, and is meant "to ensure people have the context they need to make informed decisions about what to share on Facebook." Notifications will include "timeliness" and "information about the source of the link."

Black licorice may look and taste like an innocent treat, but this candy has a dark side. On Sept. 23, 2020, it was reported that black licorice was the culprit in the death of a 54-year-old man in Massachusetts. How could this be? Overdosing on licorice sounds more like a twisted tale than a plausible fact.

Just in time for Halloween, scientists at Cornell University have published some frightening research, especially if you're an insect!

The ghoulishly named ogre-faced spider can "hear" with its legs and use that ability to catch insects flying behind it, the study published in Current Biology Thursday concluded.

"Spiders are sensitive to airborne sound," Cornell professor emeritus Dr. Charles Walcott, who was not involved with the study, told the Cornell Chronicle. "That's the big message really."

The net-casting, ogre-faced spider (Deinopis spinosa) has a unique hunting strategy, as study coauthor Cornell University postdoctoral researcher Jay Stafstrom explained in a video.

They hunt only at night using a special kind of web: an A-shaped frame made from non-sticky silk that supports a fuzzy rectangle that they hold with their front forelegs and use to trap prey.

They do this in two ways. In a maneuver called a "forward strike," they pounce down on prey moving beneath them on the ground. This is enabled by their large eyes — the biggest of any spider. These eyes give them 2,000 times the night vision that we have, Science explained.

But the spiders can also perform a move called the "backward strike," Stafstrom explained, in which they reach their legs behind them and catch insects flying through the air.

"So here comes a flying bug and somehow the spider gets information on the sound direction and its distance. The spiders time the 200-millisecond leap if the fly is within its capture zone – much like an over-the-shoulder catch. The spider gets its prey. They're accurate," coauthor Ronald Hoy, the D & D Joslovitz Merksamer Professor in the Department of Neurobiology and Behavior in the College of Arts and Sciences, told the Cornell Chronicle.

What the researchers wanted to understand was how the spiders could tell what was moving behind them when they have no ears.

It isn't a question of peripheral vision. In a 2016 study, the same team blindfolded the spiders and sent them out to hunt, Science explained. This prevented the spiders from making their forward strikes, but they were still able to catch prey using the backwards strike. The researchers thought the spiders were "hearing" their prey with the sensors on the tips of their legs. All spiders have these sensors, but scientists had previously thought they were only able to detect vibrations through surfaces, not sounds in the air.

To test how well the ogre-faced spiders could actually hear, the researchers conducted a two-part experiment.

First, they inserted electrodes into removed spider legs and into the brains of intact spiders. They put the spiders and the legs into a vibration-proof booth and played sounds from two meters (approximately 6.5 feet) away. The spiders and the legs responded to sounds from 100 hertz to 10,000 hertz.

Next, they played the five sounds that had triggered the biggest response to 25 spiders in the wild and 51 spiders in the lab. More than half the spiders did the "backward strike" move when they heard sounds that have a lower frequency similar to insect wing beats. When the higher frequency sounds were played, the spiders did not move. This suggests the higher frequencies may mimic the sounds of predators like birds.

University of Cincinnati spider behavioral ecologist George Uetz told Science that the results were a "surprise" that indicated science has much to learn about spiders as a whole. Because all spiders have these receptors on their legs, it is possible that all spiders can hear. This theory was first put forward by Walcott 60 years ago, but was dismissed at the time, according to the Cornell Chronicle. But studies of other spiders have turned up further evidence since. A 2016 study found that a kind of jumping spider can pick up sonic vibrations in the air.

"We don't know diddly about spiders," Uetz told Science. "They are much more complex than people ever thought they were."

Learning more provides scientists with an opportunity to study their sensory abilities in order to improve technology like bio-sensors, directional microphones and visual processing algorithms, Stafstrom told CNN.

Hoy agreed.

"The point is any understudied, underappreciated group has fascinating lives, even a yucky spider, and we can learn something from it," he told CNN.
