While discussing El Niño, Baliunas discusses the computer model’s prediction for the warming of the troposphere by greenhouse gases. Contrasting with the observed warming trend, the computer predicts “the air must be warming at a rate of...a quarter of a degree Centigrade per decade” (Baliunas). She uses scientific jargon to explain the warming troposphere, and it simultaneously impresses the reader and allows them to trust Baliunas. Next, Baliunas discusses the link between El Niño and temperature records saying “during the period of overlap, the correlation coefficient between the two data sets...is well over 99 percent” (Baliunas). Using the statistical term to describe the relationship and it helps develop her voice as an educated scientist. Lastly, Baliunas discusses if the sun’s energy output was “superimposed on [a] reconstructed temperature record...the two show a good correlation” (Baliunas). Baliunas use of “superimposed” and “reconstructed” shows her precise and factual diction. Baliunas meticulous choice of diction ranging from scientific to statistical shows her range and voice as a scientist.
Baliunas deduced that rising surface temperatures are caused by natural phenomena in the Pacific Ocean and increased energy from the sun using statistics, scientific studies, and temperature records. She discusses her theory with precise, accurate diction that demonstrated her career. People may start to question their assumptions about climate change after Baliunas’ convincing argument that the increased temperatures are natural and not
