Climate Change was around before and after Homo Sapiens walked on this planet So, whilst man has certainly had an effect on climate via increased water usage, industrialisation, huge population growth etc, it is extremely difficult to distinguish between the impact of these changes and natural occurrences.
Whilst I am convinced that the biggest impact on the world's climate is caused by natural means and not man made, we will need to be much careful in harnessing and conserving our water resources.
Could the next war be over water especailly in the Midde East, which is so deprived of this essential commodity?
Incidentally did Homo Sapiens have any effect on the last Ice Age?
