Half the population of the United States traveled across borders in 2012. Ten of the population traveled to Carrabin in 2012 (United States). Traveling is a way of life for some and a major influence on US culture. Despite the recent recession, travel has become increasingly popular among Americans. Some believe that the increased popularity of travel is the result of global climate change. Global climate change refers to the natural change in global temperatures over time. The term global warming, while common, is a misnomer, since in some scenarios it is possible that part of the earth could cool, even as most of the planet warms (Frodeman). In the media, climate change is often mistaken for the words “global warming”. This is a cut of words. The two are different. If you combine the two, you get this: Global warming is human-induced climate change. The fact is that climate change can and does occur at any time, and global warming is just a theory. This is where many non-scientists go wrong. Theories are scientific evidence, collected over time and accepted as a valid explanation of the evidence. Theories are different from hypotheses and scientific laws. A hypothesis is a plausible hypothesis, based on knowledge, but requiring continuous testing for further development (into a theory). Laws are virtually incontrovertible scientific facts. For example, if you throw a ball straight up, it will come down. Gravity is a law of science. Climate change is difficult to express directly, as knowledge of climate change generally falls under the classification of “weather.” However, geologists have known since the mid-nineteenth century that local and global climates undergo changes through… half of article… pedia of science, technology and ethics.
