Fossil Fuel Fallout
Carbon dioxide and other air pollution is collecting in the atmosphere like a thickening blanket, trapping the sun’s heat and causing the Earth to warm up. Coal-burning power plants are the largest U.S. source of carbon dioxide pollution — they produce 2.5 billion tons every year. Cars are the second-largest source, creating nearly 1.5 billion tons of CO2 each year. To compound the issue, deforestation has occurred at an unprecedented rate across the globe. Plants (including trees), use carbon dioxide and release oxygen. Although local temperatures fluctuate naturally, over the past 50 years the average global temperature has increased at the fastest rate in recorded history. The 10 hottest years on record have all occurred since 1990. Global warming is already causing damage in many parts of the United States. In 2002, Colorado, Arizona and Oregon endured their worst wildfire seasons ever. The same year, drought created severe dust storms in Montana, Colorado, and Kansas, and floods caused hundreds of millions of dollars in damage in Texas, Montana, and North Dakota. Since the early 1950s, snow accumulation has declined 60% and winter seasons have shortened in some areas of the Cascade Range in Oregon and Washington. Of course, the impacts of global warming are not limited to the United States. In 2003, extreme heat waves caused more than 20,000 deaths in Europe and more than 1,500 deaths in India. And in what scientists regard as an alarming sign of events to come, the area of the Arctic’s perennial polar ice cap is declining at the rate of 9 percent per decade.From the Beginning: The Industrial Revolution
