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

Starbucks is opening the world's largest Roastery in Chicago.The company said the restaurant will open on November 15, overtaking Tokyo as its biggest location of the lavish offshoot. The four-story Chicago Roastery is 43,000 square feet and is replacing a former Crate and Barrel location in the city's Magnificent Mile neighborhood.Roasteries are intended to be tourist attractions in themselves. They feature specialty coffees and teas, on-premise roasters and massive coffee casks where freshly roasted beans are held.

Regular nonstop flights between the east coast of Australia and London or New York could soon become a reality.In preparation, Australian airline Qantas has announced three test flights, with 40 people traveling directly from London or New York to Sydney, to see how the human body copes with 19 solid hours of air travel.Qantas previously announced its goal of operating direct flights between London, New York, and three Australian cities -- Sydney, Brisbane and Melbourne -- by 2023.The test flights scheduled for October, November and December will move the airline closer to that target and enable Qantas, alongside medical experts, to test the health and wellbeing impacts on passengers and crew.Bjorn Fehrm, an aeronautical and economic analyst at Leeham News, explains to CNN the appeal of the ultra-long-haul flight, as opposed to a more typical two-part journey stopping in Dubai or Singapore.There's no layovers, no extra journeys through customs and no transfer stress, he points out. "You can plan it so you fly over night, and you could arrive to actually have a productive day the next day as well," says Fehrm. "It's going to be businesspeople that fly this way."If the 19-hour flight becomes a reality, it's likely to cost travelers more. "It's cheaper for the airline to do two separate flights," Fehrm says. "But some people are prepared to pay the extra price of that ticket."Before the trials begin later this year, three Boeing 787-9 Dreamliners, fresh off the production line, will be flown from Boeing's factory in Seattle to either London or New York.After the test flights -- two from New York, one from London -- the new planes will enter commercial service. Most of the people on board the test flights will be Qantas employees, so seats won't be available for purchase.Researchers from Sydney University's Charles Perkins Centre, Monash University and the Alertness Safety and Productivity Cooperative Research Centre -- a scientific program backed by the Australian government -- will examine the impact of the long flight on those on board.Passengers in the main cabin will wear monitoring devices, and experts from the Charles Perkins Centre will study how their "health, wellbeing and body clock" are impacted by a set of variables that include lighting, food and drink, movement, sleep patterns and inflight entertainment.Monash University scientists will focus on the flight crew, recording their melatonin levels before, during and after the flights, as well as studying brain wave data from electroencephalogram devices worn by the pilots.This information will then be shared with the Civil Aviation Safety Authority "to help inform regulatory requirements associated with ultra-long haul flights," Qantas said in a 2765
