What I don't really get is how you can possibly take the last 100, or even the last 1,000 years and use it as a trend. I mean, the earth is what, about 4.5 billion years old. So in order to even have a trending period that can give a signficant trend, you need at least 0.05% (and that's being really generous). So 0.05% of 4.5 billion is 2.25 million years.
Is there evidence that the Earth has been steadily warming up for the last 2.25 million years? If not, how can people even claim global warming is a trend?
