Global Warming is bull

this is a quote from Bobby Webster..."That mankind is causing global warming is far from being a proven fact. It is true that records show that average temperatures have increased over this century; however, temperatures actually dropped slightly between the 1930s and the 1970s. This was not associated with a reduction in fossil fuel emissions - in fact, they were increasing over this period. If the 'greenhouse gases' are responsible for global warming, how can this be?Accurate records simply do not cover a long enough period to be useful. The earth's average temperature varies naturally through time, and we so far have few or no good explanations to explain events such as the ice ages. Indeed, there was a 'mini-ice age' around four hundred years ago, during which the Thames in London repeatedly froze over during winter; this was followed by an intensive but natural period of 'global warming'. We do not have enough information to say that current trends are not simply natural variation."


How do we explain this?

Global Warming Debate

I'm curious to what the general public believes about global warming. There are two sides, one says this is the normal cycle of the earth, and that the temperature has risen before.

The other says no, it's the fossil fuels we burn....... what do you have to say.?
