Is global warming manmade?

For decades now there has been government agencies and politicians stating that global

warming has been caused by human emission activities around the world. Many scientist have

have been attempting to debunk the notion that global warming is caused by humans. The

information and research discussed in this paper will attempt to show exactly how human

activities have not been the source of “global warming.” Before understanding how humans

have not caused global warming we must first understand exactly what global warming is.

According to the IPCC (Intergovernmental Panel on Climate Control), Global warming is

the “increase in the average temperature of the Earth's near-surface air and the oceans since the

mid-twentieth century and its projected continuation.” Global surface temperature increased

0.74± 0.18 °C (1.33 ± 0.32 °F) during the 100 years ending in 2005. The aforementioned Panel

attributes Anthropogenic (man-made) greenhouse gases to most of the observed temperature

change in the last 100 years and that natural phenomena such as solar variation and volcanoes

have had a SLIGHT warming effect but a COOLING effect since then. Since these basic

conclusions have been endorsed by 40 scientific societies and academies of science, we have no

choice but to accept them as true for the moment.

Climate model projections summarized in IPCC reports indicate that global

surface temperature will likely rise a further 1.1 to 6.4 °C (2.0 to 11.5 °F) during the twenty-first

century. The uncertainty in this estimate arises from the use of models with differing climate

sensitivity, and the use of differing estimates of future greenhouse gas emissions. Some other

uncertainties include how warming and related changes will vary from region to region around

the globe. Most studies focus on the period up to 2100. However, warming is expected...
