There are also influential political interests in various industries who are lobbying Congress to promote data that indicates climate change is not related to human activity.
The lab experiments support the human origins of global warming through comparing average temperatures and fuel emissions over the course of the industrial era and beforehand.
Materials and Methods:
The methodology of the study was to examine the standard deviation of temperatures spanning from 1860 (the beginnings of the industrial revolution) to 2000. Negative values represent a cooler deviation from the norm, and positive values represent a warmer deviation from the norm. Until the turn of the century, deviations were trending lower, when suddenly they began to increase around 1980 (Step 2, p.1).
Of course, the problem with such data is that climactic averages have only been tracked relatively recently. However, projected past data suggests the previous 1,000 years were characterized by a general cooling trend, making the current trend in the wake of industrialization anomalous (Step 2, p.4). Carbon dioxide emissions have also been increasing stratospherically rising since 1960, and the most...
Data from the pre-industrial era suggests a general cooling trend. This changed strikingly as carbon dioxide emissions related to human activity increased.
The data supports the initial hypothesis. Carbon dioxide emissions and fossil fuel consumption experienced a notable spike fifty years ago, which was also correlated with a spike in global warming. This suggests in a morally neutral fashion the politically charged conclusion that for the warming trend to be reversed, lifestyle changes are demanded of the world's population, as the modern lifestyle has caused global warming.

A closer look at a soap bubble basically reveals swirling colors that are usually in motion with the forces that keep these colors swirling being likened to those that create weather. The weather is moved around by very delicate forces which are the variations between cool and warm areas and their slight variations in constituents. Similar to the complexity of these processes, it's difficult to understand the nature of
Global warming is due to human actions. Since the Industrial Revolution, there is an increase in the greenhouse gases all over the world. This, consequently, has turned out to be the cause of a slow but sure increase of the temperature of the earth's lower atmosphere. This phenomenon has been given the name of Global Warming ("Global Warming," 2009). The greenhouse effect is a natural process due to which the temperature of
These effects would be unfairly harsh on developing nations, who had little to do with creating the problem; this is one of the reasons that recent international talks in Copenhagen have stalled (WGW 2009). Not only would these countries not be able to develop as quickly and have healthier populations and more stable governments, but industrialized nations would also see negative economic impacts, making many wary of making any
Global Warming The Debate of Global Warming Global Warming is a serious problem for our planet and our generation. This is a topic of much concern and debate. The climate change in our environment has been the center of many debates. Global warming is the increase in temperature in the earth's surface and in the oceans. This increase in temperature and potential continued increase in temperature is a significant threat to the
Global warming occurs due to the rise in temperature. The trapping of light and heat from the sun causes this rising of temperature. Nitrous oxide, carbon dioxide, methane and water vapor are the green house gases, these gases trap the light and heat from the sun, and as a result, the temperature rises. This global warming hurts a large number of people, plants and animals living in the earth. There
Global warming is becoming an international dilemma nowadays. The countries are determined to put a stop to global warming but it requires steps that are not easy to take because of their cost. According to a research, if the current trend of global warming continues, the cost of global warming will be as high as 3.6% of the total GDP. Out of all the impacts, just four will cause enough
