A Youtube video of Fox News host Tucker Carlson's show.

Viewers who click on YouTube videos about climate change, climate science and global warming may now see a small pop-up at the bottom of their videos providing facts on the issue at hand, as reported by Zahra Hirji at Buzzfeed News.

Why it matters: YouTube does not make the full list of conspiracies that it wishes to mediate with third-party information publicly available, but Buzzfeed News' reporting shows that climate-related hoaxes are part of that set.

Climate hoax videos aren't the only target. Disclaimers have also been found on videos published by RT, a Russian television network funded by the Russian government.

  • The messages will also accompany videos on Dulce Base, Lilla Satsjöbadsavtalet, the 1980 Camarate air crash, the Federal Emergency Management Agency, the Kecksburg UFO incident, and the MMR vaccine.

The big picture: Many social media platforms, like YouTube and Facebook in particular, have been criticized for creating news echo-chambers for consumers.

  • For example, if a viewer were to watch a video challenging the broadly-accepted scientific consensus on climate change, they would be presented with more videos of a similar vein, with no guarantee of an encounter with accurate scientific material.

In an effort to get around this problem, while also avoiding making editorial judgement calls to censor some of the content on their platforms, several companies are opting to give users more context around certain topics so they can broaden their perspective.

  • Still, the efficacy of these efforts, which will be measured in part by clicks on the disclaimers, remains to be seen.

YouTube CEO Susan Wojcicki announced in March that the site would begin displaying facts from Wikipedia and other third-party sources alongside controversial or hoax videos that challenge widely accepted facts, like the moon landing, details on school shootings, and now climate change.

  • Facebook has a similar fact-checking partnership with Wikipedia and other organizations.

The system isn't perfect, and YouTube and other platforms are still working to refine the effort.

  • Buzzfeed News reports that the disclaimers also appear below videos that propagate accurate scientific information about climate change.
  • Similarly, a time lag exists between the time a Wikipedia page is updated and when the change appears in the pop-ups.

What's next? YouTube seems to have chosen to use Wikipedia's material without consulting them first, but the two are forging ahead with the experimental partnership nonetheless, according to Engadget.

Editor's note: the photo caption has been corrected to remove a reference to Stossel's statements about climate change.

Texas abortion law remains in effect after appeals court ruling

A U.S. appeals court transferred a challenge to Texas' law banning most abortions after about six weeks of pregnancy to the state supreme court in a 2-1 vote on Monday evening.

Why it matters: The 5th U.S. Circuit Court of Appeals' decision means the country's most restrictive abortion law can remain in place for the time being.

At least two people are confirmed to have died in Tonga following the undersea volcanic eruption that sent tsunami waves toward the island nation and across the Pacific over the weekend, officials said Monday.

The big picture: Officials reported major damage along the western coast of the main island of Tongatapu, where the capital, Nuku'alofa, was covered in ash and dust, including on the runway of the airport. A New Zealand Ministry of Foreign Affairs spokesperson told Axios over the phone that two people had been confirmed to have died in the disaster.

The CEOs of leading U.S. air cargo and passenger carriers on Monday warned the Biden administration there could be "catastrophic disruption" after AT&T and Verizon deploy a new 5G service this week.

Driving the news: They said in a letter to Transportation Secretary Pete Buttigieg and other top federal officials ahead of the C-Band 5G service's deployment Wednesday that "the nation's commerce will grind to a halt" and "could potentially strand tens of thousands of Americans overseas."
