Global warming: Reasons why it might not actually exist


2008 was the year man-made global warming was disproved, according to the Telegraph's Christopher Booker. Sceptics have long argued that there are other explanations for climate change other than man-made CO2 and here we look at some of the arguments put forward by those who believe that global warming is all a hoax.


Last night we were awakened by another thunderstorm, not unlike the one which blacked out the island a few days ago. My wife observed that we have never seen this much lightning in the many years we have lived here on Oahu. And this is certainly true.

Now then, quick meteorology lesson. Lightning is the result of static electricity created by the interaction between tiny rising droplets of water and falling bits of ice all within the storm cloud system. So, when you have lightning, it means that somewhere above you there is hail. The more lightning, the more hail. So, for Hawaii to be seeing an increase in lightning storms, it means we not only have hail high in the sky over Hawaii, we have MORE of it this year than in previous years. This is consistent with the fact that this year's temperatures have been cooler.
