    Perspectives on global warming consider the increased presence of carbon dioxide and other greenhouse gases in the atmosphere, increments in atmospheric temperature, and the effects of such temperature rises. According to the National Geographic, global warming defines the progressive rise in the earth’s atmospheric temperature as a result of the greenhouse effect. Despite existing for millennia, outstanding debates on this topic commenced in the last two centuries with the first contribution from Svante Arrhenius in the year 1896. However, the last half of the twentieth century got characterized by increasing contestations as to whether the phenomenon is reality or a fallacy. Scientists against global warming claimed that other natural sources of carbon exist. Further, they point out that carbon dioxide is not the only greenhouse gas. Finally, they indicate that global warming is not related to extreme weather and catastrophic occurrences. However, these claims remain unfounded as the phenomenon of global warming is real. Evidence for the occurrence of global warming encompasses increasing atmospheric concentration of greenhouse gases, continuously rising global temperatures, the melting of Arctic and Antarctic ice, and changes in sea levels. Notably, numerous claims and counter claims characterize the topic to a largely confusing extent. Opponents of this idea indicate that limits predicted in the early 1990s have not been achieved to date. One outstanding claim relates to the fact that the coldest years in the last century occurred in the last quarter of that century. Another opposing claim points to the fact that other massive sources of carbon dioxide and other greenhouse gases exist. This claim dismisses human activities as a possible cause of global warming. Suggested sources for these claims include volcanic activities and other natural processes. Perhaps, the most outstanding of these claims points to the presence of water vapor as a greenhouse gas. Thus, no human activity causes the increase of water vapor in the atmosphere. A keen review of these claims reveals fundamental flaws in the way they are presented. Statistics from the Woods Hole Oceanographic Institution, Yale Project on Climate Change, NASA Goddard Institute for Space Studies, and the Scripps Institute of Oceanography among others indicate that average temperatures have risen in the last hundreds of years. These institutions study the effects of climate change on glaciers, polar ice, the atmosphere, and oceans. Perhaps, a clear indicator of this can be drawn from the melting of Arctic and Antarctic ice that has taken place for long. A review of previous and current levels of ice indicates that levels of ice have reduced by volumes of thousand of cubic meters. Resultantly, sea levels have kept rising by at least 0.03 cm every year. In the last one hundred years alone, the limits of atmospheric carbon dioxide have risen from 290 to 400 parts per million. This is enough to indicate that atmospheric carbon is substantially increasing. Alongside other greenhouse gases, these elements cause atmospheric heating by shielding reflected rays from escaping into the space. It may be true that human activities are not directly related to rises in the levels of water vapor. However, water vapor only increases in the atmosphere when water bodies are heated. This gets initiated by the presence of other greenhouse gases. The effect then becomes replicating as more water vapor escapes into the atmosphere. In conclusion, global warming defines the progressive rise in the earth’s atmospheric temperature as a result of the greenhouse effect. Recent claims have pointed out that claims related to global warming are false and fallacious. However, such claims remain nonfactual. Verifiable evidence for the occurrence of global warming encompasses increasing atmospheric concentration of greenhouse gases, continuously rising global temperatures, the melting of Arctic and Antarctic ice, and changes in sea levels.   ADDITIONAL INFO: Check my reference for "write my essay" on Global warming  Climate change: How do we know?
