GMAT 800 RC: Renewable Energy Propagandists

When Al Gore's 'An Inconvenient Truth' earned awards and accolades and demonstrated Global Warming as a human-induced phenomenon, not many scientists looked beyond the research papers from 'US Global Change Research Program'. The 2006 documentary was a fodder to Global Warming alarmists, who forgot the fundamental fact that the average temperature has climbed by only 1.4 degrees Fahrenheit (0.8 Degree Celsius) since global temperatures began to be monitored systematically from 1880.

The research by Andrew Dessler and his team from Texas A&M University has confirmed the previous debated theory that Water Vapor is the most contributing greenhouse gas, doubling the climate warming caused by the increased levels of CO2 in the atmosphere. Atmospheric Infrared Sounder (AIRS) on NASA’s Aqua satellite became the first device to measure water vapor at all altitudes within the troposphere. Using AIRS, the scientists measured the humidity along the lowest 10 miles of the atmosphere. The level of humidity along with observation about carbon dioxide and other greenhouse gases allowed researchers to grasp the interplay of the three major contributors of Global Warming. More than the increase in temperature, the compounding nature of Water Vapor is what worrying scientists around the world. Increase in water vapor leads to a warmer temperature that results in more water vapor emitted into the air.

Although Carbon dioxide (CO2) is the primary contributor of greenhouse gas emitted through human activities, accounting for 82% of all U.S. greenhouse gas emissions in 2012 - renewable energy propagandists conveniently forget that it is the naturally occurring heat emitted from our body that is causing the increase. Perhaps an initiative to control birth rate would halt the supposed increase in Global Temperature.

Q) What assumption does the author make when he states, “renewable energy propagandists conveniently forget that it is the naturally occurring heat emitted from our body that is causing the increase”


a) CO2 is the primary contributor of greenhouse gas

b) The Major contributor of Global Warming is Water Vapour

c) Global Temperature recorded from 1880 is enough to understand Global Warming

d) Renewable Energy Propagandists are responsible for the theory of 'Global Warming'

e) U.S Greenhouse gas emissions is responsible for Global Warming

Q) The primary purpose of the passage is to

a) To demonstrate that global warming is natural

b) To show that CO2 is not the primary contributor of global warming

c) To highlight the development of AIRS and its contribution in studying global warming

d) To question human induced global warming

e) To present the compounding effect of Water Vapor in Global Warming
