Global Warming Dbq Analysis
When making policies that may affect global warming, world leaders must consider key issues such as greenhouse gas emissions, carbon dioxide emissions and changes in surface temperature because are these issues that have the most prominent impact on global warming.
Greenhouse gas emissions are important to consider when making global warming policies. Greenhouse gases are the cause of the greenhouse effect on our earth, which leads to the warming of the earth’s surface over time, also know as global warming. Scientists are trying to slow down this process, and, “in February the Kyoto Protocol to reduce global warming took effect, requiring participating countries to reduce their greenhouse gas emissions to below 1990 levels over a five-year …show more content…
This is important to consider because “in the 20th century, the world’s average surface temperature rose by approximately 1 degree Fahrenheit, the fastest rate in any period over the last 1,000 years” (Source A). Although this one degree change may not seem drastic, over the coming years it can dramatically increase the temperature of the earth if the human population does not intervene. This is why regulating the changes in surface temperature is so important to global warming policies. In addition to this, the graph is Source B clearly depicts that the measured ocean temperatures over approximately 150 years, from 1880-2004, have increased rapidly, especially since the mid-1900’s (Source B). This supplements the data from Source A, and clearly interlinks changes in surface temperature to global warming. Lastly, it was show that the “best estimates suggest an average temperature increase of 1.4-5.8 [degrees Celsius and] a sea-level rise in the order of a metre…” (Source E). No matter what the increase is, the fact that the surface temperature on the Earth is increasing is a wakeup call to the human race on how their daily lives are contributing to global warming.
