Science says humans are the driving force behind climate change. But we have to go back centuries to get an idea of how we got to where we are today.In the 1600s, people started using coal for fuel more often than wood. It was more widely available and produced more energy.The industrial revolution was a turning point. That’s when America started burning more fossil fuels for energy.By the early 1800s, people were using high-pressure boilers to fuel coal-powered engines. That included trains, steamboats, and ships.The first theory of human-caused climate change came about in 1838. A physicist proposed that water vapor and carbon dioxide could trap heat in the earth's atmosphere.Then, in 1876, a Russian scientist observed that - since the industrial revolution - Siberian glaciers started melting.Scientists say much of that water ended up in the ocean and raised sea levels.Sea levels are between five and eight inches higher today than they were in 1900.Some climate change critics argue temperatures are going down in some places.Scientists say that's somewhat true but that, overall, earth's temperatures are on the rise.Critics also argue humans aren't behind climate change.Scientists say there's a direct correlation between human carbon emissions and rising temperatures.Some scientists believe our "right now" culture will make the crisis worse. They say things like same-day delivery and frequent air travel could all put more carbon into the atmosphere. That the carbon traps heat that then warms the earth. 1539

Student journalists at The Daily at Northwestern University are caught in a hailstorm of debate about journalism ethics after the paper opted to apologize for publishing pictures of students protesting a campus visit by former Attorney General Jeff Sessions. The newspaper relented after demands came from the protesters to take down photos of the protest over fear of repercussions from the university.While the paper's official stance claimed that they were minimizing harm to the protesters by removing the photos, a dean for the university said that the journalists were being bullied by the protesters upset by the coverage. The incident took place last week when Sessions attended a College Republicans event on Northwestern's campus. The Daily said that it sent two reporters to cover the event - one directly to the event, and another to cover the protests. As part of the paper's reporting, photos of the protesters were used on a reporter's Twitter account. Also, a protester's name was published by the paper. The Daily said that by publishing the photos and name, the paper may have caused potential harm to the protesters. "Any information The Daily provides about the protest can be used against the participating students — while some universities grant amnesty to student protesters, Northwestern does not. We did not want to play a role in any disciplinary action that could be taken by the University," The Daily wrote in a statement on its website. But the dean that oversees Northwestern's journalism department said that the reporters for The Daily have an obligation to cover events like the protest of Sessions' visit to Northwestern. "I am deeply troubled by the vicious bullying and badgering that the students responsible for that coverage have endured for the “sin” of doing journalism," Northwestern Dean Charles Whitaker said. "Like those student journalists, I, too, have been approached by several student activists who were angered by the fact that they and their peers were depicted on the various platforms of The Daily engaged in the very public act of protesting the Sessions speech," Whitaker added. "I have explained to those activists that as Northwestern’s—and the city of Evanston’s—principal paper of record, The Daily had an obligation to capture the event, both for the benefit of its current audience as well as for posterity. "I have also offered that it is na?ve, not to mention wrong-headed, to declare, as many of our student activists have, that The Daily staff and other student journalists had somehow violated the personal space of the protesters by reporting on the proceedings, which were conducted in the open and were designed, ostensibly, to garner attention."While some have mocked the decision to apologize, the 2784

Prosecutors in New York City hit indicted singer R. Kelly with new bribery charges Thursday that appear to be related to his 1994 marriage to a teenager.A revised indictment in federal court in Brooklyn accuses R. Kelly of scheming with others to pay for a "fraudulent identification document" for someone identified only as "Jane Doe" on Aug. 30, 1994. A day later, R. Kelly, then 27, married 15-year-old R&B singer Aaliyah D. Haughton in a secret ceremony arranged by Kelly at a hotel in Chicago. The marriage was annulled months later because of Haughton's age.Defense attorney Douglas Anton on Thursday called the latest charge against his client "ridiculous and absurd."The Brooklyn prosecutors had already charged R. Kelly with racketeering, kidnapping, forced labor and sexual exploitation. They alleged he and his employees and assistants picked out women and girls at concerts and groomed them for sexual abuse.The 52-year-old singer, who is being held without bond, is scheduled to stand trial in federal court in Chicago in April on child pornography and obstruction of justice charges before facing trial in Brooklyn. 1145
