1.   Cycling in synchrony with the supercontinents and sea levels is the global climate.

2.   No one is quite sure whether there will be more or less of them in a warmer global climate.

3.   Scientists are assessing the impact of carbon dioxide on the global climate.

4.   The presence of major population centers very close to mean sea level has been much discussed in connection with global climate change.

5.   This enhancement of the greenhouse effect leads to increasing Earth-surface temperatures and global climate change.

6.   I was working on a story about global climate change and had just received a fax from a friend.

7.   Speculation that global climate change could result was largely discounted, since the smoke cloud was too low to have an impact on stratospheric climate circulation.

8.   A new centre for research into the links between society and global climate change has been opened by the Social and Economic Research Council.

9.   Removing the heat from the atmosphere will have had an effect on the global climate.
