Most people agree that climate change is a huge problem for the modern world. And for many, stopping the warming of the Earth — let alone reversing the damage that has already been done — seems impossible.

But maybe not for much longer.

A group of scientists from Trent University in Ontario, Canada, have discovered a way to use a naturally-occurring mineral to tackle one of the biggest culprits behind climate change: carbon dioxide. The buildup of it and other greenhouse gases in our atmosphere are what causes the Earth's temperature to rise. But the formation of magnesite, a mineral comprised of magnesium, oxygen, and carbon, has the power to take that harmful carbon dioxide back out of our atmosphere, Popular Mechanics reported.

On its own, magnesite forms incredibly slowly in nature — it can take up to hundreds or even thousands of years, Newsweek explained. But this team of researchers has created a method to form the mineral in just 72 days. The process is sustainable and "extremely energy efficient," said Ian Power, the project leader, in a statement at the Goldschmidt Conference, an international conference on the field of geochemistry.

Of course, forming magnesite in a lab is still a far cry from actually deploying it to fight climate change, Inverse reported. But reducing atmospheric carbon is seen as the single most powerful thing we can do to protect the Earth from worsening climate change — and this promising research may develop into a real strategy.

"I think the evidence is overwhelming" that Saudi Crown Prince Mohammed bin Salman (MBS) ordered the murder of U.S.-based Saudi journalist Jamal Khashoggi at the Saudi consulate in Istanbul, Sen. Rand Paul (R-Ky.) said on Face the Nation Sunday. "I don't think we can sweep this under the rug."

Paul reiterated his push to end U.S. arms sales to the Saudi government in retaliation for Khashoggi's killing, decrying the administration's plan to sanction other parties involved. "I think sanctions are pretending to do something without really doing anything," the senator said.

"Most of these people [being sanctioned] are in prison, other than the crown prince," Paul continued. "We need to punish who ordered this, who's in charge. ... If the president wants to act strongly, he should cut off the arm sales" over Khashoggi and because of civilian deaths in the U.S.-supported, Saudi-led intervention in Yemen's civil war.

President Trump continues to express skepticism that MBS is implicated in Khashoggi's death, and he suggested in an interview airing on Fox Sunday he might keep a close alliance with the Saudi prince even if he is guilty of the journalist's murder. He has repeatedly resisted calls to end weapons deals with Riyadh, claiming the economic toll on the United States would be too high.

President Trump discussed possible changes among his top staff, the killing of Saudi journalist Jamal Khashoggi, and more in a Fox News Sunday interview with Chris Wallace set to air at 2 p.m. and 7 p.m. Eastern.

"I have three or four or five positions that I'm thinking about [changing]," Trump said of his Cabinet lineup. "Of that, maybe it's going to end up being two. But I need flexibility." He suggested dissatisfaction with Homeland Security Secretary Kirstjen Nielsen in particular.

On Khashoggi's death, Trump maintained his skepticism despite Friday's report that the CIA has concluded Saudi Crown Prince Mohammed bin Salman (MBS) ordered the murder. Even if MBS lied to his face, Trump said, "I want to stick with an ally that in many ways has been very good." After all, Trump mused, "Who could really know [whether MBS lied]? But I can say this, he's got many people now that say he had no knowledge."

And asked by Wallace to grade his own presidency, Trump gave himself an A+ and inquired if a better mark is possible. "Look, I hate to do it, but I will do it," he said. "I would give myself an A+. Is that enough? Can I go higher than that?" Watch that clip below. Bonnie Kristian

Rain is forecast for areas affected by California's deadly Camp Fire in the coming week, with mixed effects anticipated.

The water may help contain the wildfire, which has claimed 76 lives and burned more than 100,000 acres. However, areas already burned lack live plant cover on uneven ground. "It'll bring much-needed relief to the firefighters and to the air quality," Patrick Burke of the National Weather Service told Reuters, "but there's a potential for dangerous mudslides wherever vegetation is burned away on slopes and hills."

More than 1,000 people are listed as missing in connection to the fire, but authorities say that list may contain duplicate names. Some of those listed as missing have called the police to say they are not in any danger, and the total missing count is expected to shrink as further information becomes available. Bonnie Kristian

Some of the Central American migrants traveling by caravan across Mexico toward the United States have reached the border city of Tijuana and stalled, uncertain of their next steps. Many have already been denied entry to the U.S. and are considering their alternatives, like accepting Mexico's offer of jobs and basic resettlement assistance.

"If we had work, we would stay. This has been very tiring," Orbelina Orellana, a mother from Honduras, told Reuters. "I cry a lot to not be able to feed them as I’d like," she said of her three children. "I just want an opportunity."

Complicating the decision is a newly hostile attitude toward migrants in Tijuana, which now has a conservative mayor who has argued "human rights should be reserved for righteous humans," a category from which he excludes the caravan migrants. Some Tijuana residents have scuffled with the migrants and plan to rally against their presence in the city Sunday. Bonnie Kristian

Kansas Gov. Jeff Colyer (R) is among many who have called for the resignation of a local official, Leavenworth County Commissioner Louis Klemp, for a remark in which he used the phrase "master race," a concept from Nazism.

Klemp, who is white, told consultant Triveece Penelton, who is black, they were together "part of the master race" because they both have a gap in their teeth. "I don't want you to think I'm picking on you, because we're part of the master race," Klemp said. "You know you've got a gap in your teeth. You're the master race. Don't ever forget that."

Klemp has defended the comment as a joke, and another Leavenworth County official said Klemp has repeatedly used the phrase about gapped teeth in the past. However, Leavenworth's mayor said Klemp has been more inappropriate at other public occasions and this remark demonstrates a lack of "common decency."

"Racial and discriminative language have no place in our society,' Colyer said Saturday, "and most especially when spoken by someone holding public office." Bonnie Kristian

One person was accidentally killed and more than 200 injured in large-scale protests against higher fuel taxes in France on Saturday.

An estimated 250,000 people, many wearing yellow safety vests, turned out in about 2,000 locations around the country to block roads and highways. The new tax was supported by French President Emmanuel Macron, and demonstrators called for his resignation. Macron's approval rating was at a dismal 21 percent as of October.

"We are not political people; we do not belong to a union; we are citizens," said one protester near Paris, Didier Lacombe. "The taxes are rising on everything. They put taxes on top of taxes. It is not the tax on gas; it's everything. The injustice is greater and greater."

"The price of fuel is as politically and sociologically sensitive as the price of wheat in the ancient regime," French public opinion researcher Jerome Fourquet told The New York Times. High wheat prices were among the factors leading to the French Revolution. Bonnie Kristian
