范文
Presented are two line graphs illustrating how the area of the ozone hole changed above the Antarctic and how emissions of three distinct poisonous gases altered over two decades from 1980 to 2000.
As reflected in the first chart, it is evident that the ozone hole was generally expanding. Specifically, initiating from roughly 400 thousand square km, its size gradually expanded until 1990 when it more than quadrupled, followed by a slight decline before growing steadily by the end of the period, reaching nearly 4000 thousand square km.
In 1980, while the largest amount of emissions (70 million tonnes) were derived from CFC-11, less than half of those came from CFC-12(30) and no N2O was exhausted at all. After plateauing for three years, CFC-11was controlled effectively as a stable downward trend could be noticed and in 2000 only a margin of it was released. By contrast, there was a slowly rising trend in CFC-12 discharging which approximated 60 million tonnes in the last year. Also noteworthy is that since 1990, N2O had began to be released at an accelerating rate, overtaking CFC-11 in1994 and arriving at about 40 million tonnes in 2000.
Overall, the ozone hole had been enlarged over the decades with more and more CFC-12 and N2O being released while less CFC-11 was emitted.
