Almost all scientists agree that climate change is being caused by humanity's affect on our world — but the general public isn't quite so convinced. Skeptics often say that even before humans were the reigning species on Earth, the average temperatures on the planet tended to fluctuate between warmer and colder periods. But a pair of new studies basically takes the wind out of that argument, finding solid proof that the climate change we're experiencing now is a direct result of human activity.

The studies, published on Wednesday in Nature and Nature Geoscience, both investigated our current climate and compared it to previous warm periods in the Earth's history. The first study concluded that while certain regions of the Earth have experienced fluctuations in climate before, modern climate change is the first time that the entire planet has warmed — at least in the last 2,000 years.

The second study, meanwhile, assessed the intensity of modern climate change. It found that, even during warm periods in the last 2,000 years, never before has the temperature risen so swiftly as it is now. Since the beginning of the 20th century, global temperatures have risen about two degrees, NBC News explained — and it could rise over five more degrees by the end of this century. That might not seem like a lot, but it's much faster than any other warming event in the last 2,000 years.

The conclusion? "We cannot discern any event that is remotely equivalent" to modern climate change, said Scott St. George, a geographer at the University of Minnesota, in a letter published alongside the two studies.

If there's any hope of reversing the effects of climate change, "it's time for everybody to wake up and make changes now," said Jennifer Hertzberg, a paleoclimatologist not involved in the research. Read more at NBC News. Shivani Ishwar

President Trump commuted the 40-month sentence of his friend and confidant Roger Stone, he announced Friday evening.

"Mr. Stone would be put at serious risk in prison," the White House said in a statement, calling him a "victim of the Russia Hoax that the Left and its allies in the media perpetuated for years." Stone was convicted witness tampering and making false statements to Congress, among other charges, after being indicted in former Special Counsel Robert Mueller's probe.

Stone was set to begin his prison term on Tuesday, though his lawyers did request a 60-day delay in starting that sentence, saying he would face medical risks due to the COVID-19 pandemic. The White House cited that "medical danger" in its statement announcing Trump's motion of clemency.

Trump called Stone "very unfairly treated" when talking to journalists earlier Friday, and was reportedly expected to pardon him soon. Still, Stone told journalist Howard Fineman on Friday he didn't want a pardon because it implies guilt. Kathryn Krawczyk

Amazon employees can apparently download TikTok again.

On Friday, The New York Times broke the news that Amazon sent an email to employees telling them they had to delete TikTok from their cell phones due to "security risks." Staffers were reportedly told they needed to have the app deleted by Friday in order to continue accessing their Amazon email. It was major news that generated headlines across the internet following Secretary of State Mike Pompeo saying earlier this week the United States was considering potentially banning the Chinese-owned app.

But just hours later, Amazon says actually, forget about all that, as the company now claims it sent the email to employees accidentally.

"This morning's email to some of our employees was sent in error," an Amazon spokesperson told The Verge. "There is no change to our policies right now with regard to TikTok."

If it was an error, it's quite a mistake to make given all the attention the news got, although considering the company did evidently have an email ready to go for this scenario, "right now" may be the key phrase in that statement. Brendan Morrow

Valentina Sampaio says she has overcome "snickers, insults, fearful reactions, and physical violations," to become Sports Illustrated's first transgender swimsuit model.

Sampaio, who writes for SI that she was "born trans in a remote, humble fishing village in northern Brazil," will appear in SI's annual swimsuit edition out July 21. She's been on the cover of Vogue Brazil and had a Victoria's Secret campaign last year, and now helps SI take its latest step in including groundbreaking, diverse models on its pages.

In an essay for SI, Sampaio describes how "Brazil is a beautiful country, but it also hosts the highest number of violent crimes and murders against the trans community in the world." "Being trans usually means facing closed doors to peoples' hearts and minds," Sampaio continues, which often holds trans people back from "growing up in a loving and accepting family, having a fruitful experience at school, or finding dignified work."

"I recognize that I am one of the fortunate ones, and my intention is to honor that as best I can," Sampaio said, thanking SI for "seeing and respecting me as I truly am." Read all of what Sampaio has to say about her big gig at Sports Illustrated. Kathryn Krawczyk

A moratorium on political ads may be coming to Facebook this fall.

Facebook is considering imposing a ban on political ads "in the days leading up to" November's presidential election, Bloomberg reported on Friday. As of now, the idea is "still only being discussed," the report says.

Facebook has long faced criticism for its decision not to fact-check political ads, something CEO Mark Zuckerberg has defended by saying that "people should decide what is credible, not tech companies." Last year, more than 250 Facebook employees signed a letter arguing that this policy "allows politicians to weaponize our platform by targeting people who believe that content posted by political figures is trustworthy."

Facebook is now facing an ad boycott from companies urging it to crack down on hate speech and misinformation, and an independent audit concluded this week that it "has been far too reluctant to adopt strong rules to limit misinformation and voter suppression."

According to Bloomberg, part of the reason the potential ad ban hasn't been decided upon is that there's still some concern it "could hurt 'get out the vote' campaigns, or limit a candidate's ability to respond widely to breaking news or new information." The New York Times is also confirming the news of the potential ban while cautioning that it's still possible Facebook will decide against it and "continue with its current political advertising policy."

Facebook previously announced it would let users opt out of seeing political ads altogether, with Zuckerberg saying last month, "for those of you who've already made up your minds and just want the election to be over, we hear you."

Back in March, everyone in the U.S. but essential workers scrambled to adapt to remote work to stem the spread of COVID-19.

Well, everyone but President Trump's 2020 campaign headquarters. The Arlington, Virginia, office has remained packed with workers through the past four months, only closing this week for its first deep cleaning in a while because a staffer tested positive for the virus, people familiar with the HQ's operations detail to Politico.

Social distancing doesn't exist inside the Trump HQ, where "dozens of staffers" are "often sitting in close proximity to conduct phone calls and other urgent campaign business," three people tell Politico. Staffers wear masks outside the office "in case they're spotted by reporters," but are free to take them off inside, Politico continues. Except free might not be the right word for it: One person told Politico "You get made fun of if you wear a mask. There's social pressure not to do it.”

All of that became obvious when Vice President Mike Pence tweeted a picture from a visit to the headquarters last month showing a jam-packed, maskless office. The tweet has since been deleted, but it sparked questions into whether Virginia officials would step in and enforce the state's social distancing guidelines and mandatory mask policy. Gov. Ralph Northam (D) ultimately declined to get involved so he didn't "get bogged down in a political fight," an individual familiar with the situation told Politico.

"The campaign takes the health and safety of our staff very seriously," spokesperson Tim Murtaugh told Politico. That includes a "weekly deep cleaning, daily temperature checks," and "widely available masks and PPE, and testing of staff both before events and before returning to the office," Murtaugh said.

FedEx is threatening to remove its signage from the Washington Redskins' stadium unless the team's name is changed, The Washington Post reports.

The shipping company, which owns the naming rights to the Washington Redskins' stadium under a more than $200 million deal signed in 1999, recently announced it was asking the team to change its controversial name, and the Post is now reporting that FedEx informed the Redskins in a private letter that unless it does so, "it will remove its signage from the stadium after the NFL's 2020 season, six years before the deal's expiration."

This was reportedly communicated in a letter from FedEx's general counsel sent on July 2, the same day the statement saying that FedEx was requesting a name change was released. The company privately described how the Redskins' name, which has long been criticized as racist, "poses the risk of harming FedEx's brand reputation and is inconsistent with its commitment to a more inclusive society," the Post writes.

Following FedEx's initial statement that it was requesting the name be changed, the Redskins announced it would begin a "thorough review." In the days since, Redskins merchandise has been pulled from Amazon, as well as Walmart, Target, and Dick's Sporting Goods. Brendan Morrow
