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

Strong opioid dosage is the topic of a two-day public hearing by the Food and Drug Administration — which is trying to discern the benefits and risks.For Katrina King, her opioid addiction began with a back injury. It got so bad she spent two years behind bars after getting caught with forged prescriptions. King blames being put on high-dose medication too strong for her injury."The extended release — introducing that into the picture as such a potent dose so early in my diagnosis without trying anything else — ended up being catastrophic," she said.Some people have suggested the FDA remove high-dose opioids form the market to fight the deadly epidemic. Others argue the stronger meds are necessary to manage pain for some patients and getting rid of it could worsen pain for those people, leading to potential suicides."We don't want to cause additional suffering for people who have unmanageable pain that does make them feel they don't want to live anymore. On the other side of that, I would challenge the pharmaceutical industry and the FDA to come up with other methods of pain control," King said.The FDA will review public comments and decide whether to make change, which could include tougher regulations on reducing the use of high-dose opioids. 1276

Rolfi Ferreira Cruz, the accused gunman in the attempted murder of David Ortiz, says the former Boston Red Sox slugger was not his intended victim, according to video released by the media in the Dominican Republic.The video shows Ferreira Cruz saying through his jail cell window to journalists, "It wasn't David" and "I got confused by his clothing."According to Dominican media outlets, Ferreira Cruz said the people who hired him for the hit only told him the color of the clothing of the intended target.Prosecution spokesman Erick Montilla responded to the media reports, saying he doubted any Dominican would not recognize David Ortiz and that Ferreira Cruz was making up a "story" to avoid being "lynched" in jail."He can say whatever he wants in an interview," Montilla said. "What matters is the investigation and what he said in the interrogation."He added, "If you observe the video (of the shooting), he goes directly to where the victim is and shoots without hesitation."Ortiz, 43, was at a Santo Domingo nightclub Sunday night when he was shot in the back. Television host Jhoel Lopez was also shot. 1126
