You may have heard the tales of President Trump tearing up documents after reading them, leaving aides to try to glue them back together. Well, that flippant attitude toward recordkeeping has left historians frustrated, as Trump's papers begin their migration to the National Archives and Record Administrations, The Associated Press reports.

In addition to mishandling records, AP notes, Trump also showed a willingness to try to erase certain records, like when he confiscated an interpreter's notes after he spoke with Russian President Vladimir Putin in 2017, driving speculation that the two talked about Russia's 2016 election interference in some capacity. Per AP, Trump's staff also had to be reminded not to use private email or text messaging systems to conduct official business and, if they did, to take screen shots of the exchanges and copy them into official email accounts, which are preserved. Still, it's unclear how closely that was followed.

"It's an open question to me about how serious or conscientious any of these people have been about moving them over," Tom Blanton, the director of the National Security Archive at George Washington University, told AP.

The Society for Historians of American Foreign Relations' Richard Immerman believes "historians are likely to suffer from far more holes than has been the norm" because of that potential gap. The situation could obviously be a problem for historians who rely on such records for their research, but Lee White, the director of the National Coalition for History, added that presidential records also "tell our nation's story from a unique perspective and are essential to an incoming administration in making informed decisions."

NATO Secretary General Jens Stoltenberg sees climate change as "a defining challenge for our generation and a crisis multiplier," and wants the alliance to play a key role in understanding the best way to fight it, while also adapting operations and reducing military emissions.

In an article for Politico Europe, Stoltenberg wrote that climate change is "making the world a more dangerous place." Rising sea levels and extreme weather are "devastating communities, increasing competition for scarce resources, and fueling tensions and conflict," he added. "That's why it's so crucial that NATO sets the gold standard on climate change and security, and then takes action to address it. Climate change threatens global security, so NATO must be part of the response."

On Thursday, Stoltenberg attended the U.S. Leaders Summit on climate change at the invitation of President Biden and Defense Secretary Lloyd Austin. NATO allies agreed to an "ambitious agenda on climate and security" in February, and Stoltenberg said he expects NATO leaders to approve an action plan at a summit later this year.

The plan would task NATO with using its "unique capacities and expertise to monitor and track climate change," Stoltenberg said, investing in more research and sharing data. NATO soldiers and equipment are facing extreme heat and cold, with critical infrastructure also exposed — the U.S. Department of Defense has found climate change threatens the naval base in Norfolk, Virginia, which also houses NATO commands.

There will be an assessment of the impact of climate change on NATO assets and installations, Stoltenberg said, and training and exercises will be adapted. NATO will also decrease its dependence on fossil fuels and prioritize sustainable technologies. "Climate change is a generational challenge that requires a global solution, and NATO is a powerful platform for Europe and North America to tackle shared security challenges together," Stoltenberg said.

In order to tackle climate change, it has to be "at the center of a country's national security and foreign policy," Director of National Intelligence Avril Haines told world leaders during a virtual global climate summit on Thursday.

Haines said the United States is taking this approach moving forward, adding that climate change "needs to be fully integrated with every aspect of our analysis in order to allow us not only to monitor the threat but also, critically, to ensure that policymakers understand the importance of climate change on seemingly unrelated policies."

On Thursday, the CIA said it is adding a new environmental category to its World Factbook, which will provide data on climate, pollution, infectious diseases, and food security for different countries. The intelligence community's most recent worldwide threat assessment said that the extreme weather caused by climate change will likely force people to leave areas as they become inhabitable, and this could lead to a possible surge in migration and instability. All of this would "exacerbate political instability and humanitarian crises," the report states. Catherine Garcia

Scientists have finally answered the question on all of our minds — or at least a question that was apparently on someone's mind.

After painstaking measurements, calculations, and maybe even a few taste tests, researchers have estimated the number of bubbles produced by a half-pint of "gently poured" lager to be somewhere between 200,000 and two million, ScienceDaily reports.

Not just a side effect of the fermentation process, beer bubbles are actually "important sensory elements of beer tasting" because they "transport flavor and scent compounds," writes the American Chemical Society. But why count them? The better question is why not, according to lead researcher Gerard Liger-Belair, who previously unearthed the number of bubbles in a glass of champagne (spoiler: it's about a million).

Using high-speed photography, intricate carbon dioxide measurements and expert calculations, Liger-Belair and his team were able to track bubble formation from the minute a lager was poured to the second it went flat, reports CNET. But because different beers and different glasses can greatly influence that all-important bubble count, researchers left a pretty wide range in their estimate.

Next, perhaps Liger-Belair's team can tackle a more contentious question: how many bubbles are in regular Sprite compared to McDonald's Sprite? Brigid Kennedy

It sounds like a recent attempt by Andrew Yang to secure an endorsement in his New York City mayoral bid didn't exactly go as planned.

The candidate on Wednesday met with the Stonewall Democratic Club of New York City to seek the Democratic LGBTQ organization's endorsement, but he ended up offending its members, The New York Times reports. Yang, according to the report, "cited gay members of his staff as apparent evidence of his openness to the club's concerns, and expressed enthusiasm about the prospect of visiting" the New York gay bar Cubbyhole.

But Yang neglected to focus on "substantive issues that our membership cares about" and "came off poorly," the club's president, Rose Christ, told the Times. One member, Harris Doran, took issue with the fact that Yang "kept calling us 'your community,' like we were aliens," while the Times also cites an online chat that accompanied the forum in which one person wrote, "Gay, gay, gay. Wow. More to us than just that."

Christ also told Politico that Yang "came across like he was a tourist in New York," and member Alejandra Caraballo drew a particularly brutal TV comparison.

"When I see a candidate come in just with Michael Scott levels of cringe and insensitivity, it either tells me Andrew Yang is in over his head or is not listening to his staff," Caraballo told the Times. "Those are both radioactive flashing signs that say he is not prepared to be mayor of New York."

Yang campaign manager Sasha Neha Ahuja told the Times that "I hope Andrew continues to have space for folks to listen with an open heart about the experiences of all communities that have been deeply impacted by years of oppression," while adding that "I apologize if folks felt some type of way about it."

Cher has noticed Christopher Meloni too … but not in that way!

Appearing on The Late Late Show on Wednesday night, the singer insisted that her recent tweet about the Law & Order star — which read "CHRISTOPHER MELONI / IS EXCELLENT, / CHARISMATIC ACTOR" — wasn't thirsty and was strictly about his acting, you pervs. "I'd seen his new show, and I do, I like that show," she told James Corden, as reported by Vulture. "I think that it's an excellent show. And underrated. And the acting is really good."

But does she like more than just Meloni's a…cting? "Just because someone is an excellent actor doesn't mean you wanna jump on their bones and roll 'em around in the carpet," Cher scolded. Well that's news. Jeva Lange

In the restrained and always level-headed words of the British tabloid The Sun, Harry Styles is set to shoot "red hot sex scenes with co-star David Dawson for [a] new blockbuster."

According to the report, Styles, "one of the most lusted-after men in music," will be "shooting passionate X-rated sex scenes" for the new movie, called My Policeman, "which … will delight plenty of men and women around the world." Thank you, The Sun.

Deadline, meanwhile, has the dryer version of events: the movie is set in the late 1990s, "when the arrival of elderly invalid Patrick into Marion and Tom's home triggers the exploration of seismic events from 40 years previous: the passionate relationship between Tom [Styles] and Patrick at a time when homosexuality was illegal."
