5)*The sun is a star that provides the earth with most of its energy. The sun's temperature is about 6,000 degrees C. and its radiation of light and heat across vats distances of space weakens in proportion to the inverse square of that distance.

*"Solar-Max" satellite provided us with a 9-year old sample of solar radiation from 1980 to 1989 that proved conclusively that the sun was indeed a variable star.

*The Shanghai's observatory of the Chinese Academy of Sciences provided even further evidence of the Sun's variability in April 1990. They reported that the radius of the sun had shrunk 410 kilometers from 1715 to 1987.

*Scientists can measure the variability of the Sun by either direct measurement of its radiation, as done by the "Solar- Max", or by its emission of microwave energy.

*"The most remarkable event in the last 500 years was the 'Maunder Minimum', a 50-year period from 1650 to 1700 when there were hardly any sunspots at all, indicating a proportioned longed cooler period on the Sun.

4)*How can the sun's energy travel so far away?

*What is the cause of the sun's radiation of light?

*Why does the sun have cycles of heat and less heat?

*When did the sun appear the first time?

3) *Shrink: to reduce in size.

*Blemish: spot.

*Nimbus: radiance.

*Proxy: alternative.

2)*Repetition: the author of this argument repeats the word "maximum" at least ten times throughout his whole scripture.

*Tone: the tone of the author of this opinion seems to be serious about the sun's radiation causing global warming. Moreover, his type of writing is formal and like that he attracts audiences.

1) View point number three of the second chapter is the introduction to a completely new theory about global warming. This theory refers to the sun's radiation as the cause of global warming on Earth. According to John L. Daly, the sun has cycles in which heat is either increasing or decreasing every 10-12 years approximately. That sun's radiations are cause by blemishes in the sun that are the points in which radiation is emitted the most. There is evidence that the sun changes its radiation throughout the time, for instance, The Shanghai's observatory of the Chinese Academy of Sciences provided even further evidence of the Sun's variability in April 1990. They reported that the radius of the sun had shrunk 410 kilometers from 1715 to 1987.
