missing an introduction and thesis?

Global warming is an issue that has been debated ever since scientists uncovered the depletion of the ozone layer. not quite The earth has been experiencing drastic changes, such as climate shifts, that have no reasonable cause other than global warming. Since the 20th century, the surface temperature of the world has risen 1 degree Fahrenheit. This sort of temperature increase has not been seen over the last 1,000 years, indicating that events occurring now are contributing to the rapid rise in temperature (A). This information correlates perfectly with what scientists have been saying about global warming. Scientists discovered that the ozone layer had been depleting in the 1970’s and since then, people have not done much to stop greenhouse gases from being released into the air. In fact, in 1960 the number of passenger cars in the United States was 61,671,390. In 2008, the number shot up to an astounding 137,079,843 (National Transportation Statistics). The smog that cars emit is rich in greenhouse gases contribute to the weakening of the ozone layer. Leaders should accept the fact that global warming is a serious problem that can destroy the earth if left unchecked and they should take precautions against potential future calamities. For a last sentence you could continue wrapping up the paragraph by giving an example for policies. you talked about cars so maybe leaders should consider passing laws that budget money in ways that we can lower costs of public transportation to reduce smog.

Nature is most directly affected by global warming, and the evidence is in the increasing amount and intensity of natural disasters that are plaguing the world. In 1880, the global ocean surface temperature was -0.3 degrees Fahrenheit and it steadily decreased until about 1910. Then, from about 1960, the temperature rose higher and higher until in 2004 it was an alarming 0.5 degrees Fahrenheit (B). Hurricanes are caused when warm, moist air evaporating from the ocean mixes with the cooler air above it to form storm clouds. The constant heat exchanges combined with distortions in wind patterns create the storm. High ocean surface temperature means that the ocean is evaporating faster, therefore contributing to more natural disasters. Another fact pointing to the effect of global warming on nature is untimely bird migrations. According to a study that analyzes the reasons for early springs, robins are arriving at their spring destination several days earlier than they should, indicating that the climate is changing more rapidly than it should (F). By realizing that nature must be preserved and enriched in order to dilute the negative effects of global warming, leaders can pass policies that control deforestation and other acts that are harmful to the environment. (aw yeah good paragraph yeah)

Though leaders mean well when they think of policies that can help prevent global warming, they have to consider the economic implications of those policies. Author Mark Maslin states that currently, (states that the current amount of money set aside to stablize global warming...) the amount that will be spent to stabilize global warming is an astounding 8 trillion dollars, which is 2% of the world’s GDP (E). With so much (of)  taxpayer’s money going into this cause, one would hope that the policies that come out of it are worth the expenditure. However, solutions such as the Kyoto Protocol do not guarantee control over climate changes (maybe say that this is why America and Australia didnt adopt it...that will give you source A too ). Leaders have to acknowledge the fact that the focus should really be on the economy because only when the economy is stable can the nation afford to spend money on environmental policies. any solutions? you use a lot of data and facts (in all 3 paragraphs) but should have the analysis to back these up

Global warming is a problem that needs to be addressed as quickly as possible. By taking measures to prevent it now, leaders can rest assured that future generations will have a lesser chance of facing the hardships brought by it. address subthesis/body paragraph topics once again also bring up policies again)
