[영어 발표] [영어 보고서] 지구 온난화 - Global warming

소개글

지구온난화에 대한 조사한 글로 지구온난화를 구체적으로 설명하기 위해 대기 구조에 대한 설명붙 하여 원인, 과정, 끼치는 영향 및 과학자들의 다른 견해에 대하 조사하였습니다. 도표와 그림까지 첨부하여 논리적으로 설명하려고 노력하였습니다.

며칠밤을 세워 작성한 글로 원어민에게 감수 까지 받은 글입니다. 외국인 교수님도 무척이나 흡족해 하셨습니다.

약간 높은 가격(?)만큼 양질의 자료라 자신합니다. ^^

Global warming

Global warming is the observed increase in the average temperature of the Earth`s atmosphere and oceans in recent decades. The Earth`s average near-surface atmospheric temperature rose 0.6 ± 0.2 degrees Celsius (1.1 ± 0.4 degrees Fahrenheit) in the 20th century.
The prevailing scientific opinion on climate change is that "most of the warming observed over the last 50 years is attributable to human activities".
The increased amounts of carbon dioxide (CO2) and other greenhouse gases (GHGs) are the primary causes of the human-induced component of warming. They are released by the burning of fossil fuels, land clearing and agriculture, etc. and lead to an increase in the greenhouse effect.
An increase in global temperatures can in turn cause other changes, including a rising sea level and changes in the amount and pattern of precipitation. These changes may increase the frequency and intensity of extreme weather events, such as floods, droughts, heat waves, hurricanes, and tornados. Other consequences include higher or lower agricultural yields, glacier retreat, reduced summer streamflows, species extinctions and increases in the ranges of disease vectors.

Only a small minority of scientists discount the role that humanity`s actions have played in recent warming [see Alternative Theories below].


Causes

The climate system varies both through natural, "internal" processes as well as in response to variations in external "forcing" from both human and non-human causes, including solar activity, volcanic emissions, and greenhouse gases.
