Band 5+: You should spend no more than 20 minutes on this task. The charts below show the parts per million of carbon dioxide in the atmosphere and the average temperature of four cities from the year 1750 to 2000. Write a report for a university lecturer describing the information. You should write at least 150 words.

The charts illustrate the amount of carbon dioxide in the atmosphere measured in parts per million and the average temperature measured in centigrade respectively in the cities Seoul, New York City, London and Los Angeles between 1750 to 2000.

Overall, an upward trajectory in the amount of carbon dioxide in the atmosphere can be noted. The temperature in Los Angeles and new York also increased while it mainly remained constant in Seoul and fluctuated slightly in London.Also shown is as carbon dioxide increase so does the temperature.

In 1750, only London had its temperature measured and it was about 10 centigrade through out the years however it fluctuated until finally reaching to a constant 13 . It was not until 1900 where all locations were recorded where Los Angeles recorded the greatest temperature of about 18 centigrade and rose up to 23 by 2000.

New York was first measured in the 1800s with an initial estimate of 10 centigrade with remained within the range of 10- 15 over the years. Seoul was included last with a first estimate of about 12 and had an increase every half a century to finally reaching about 17 centigrade.
