As MD pointed out, the earth has been around 4.5 billion years. What he did not mention, was that for the vast majority of that time, there was no life on earth.

I don't disagree with your assessment and yes there are several planetary examples of temperature extremes. What you and others like you who blame Man for causing these changes don't take into account is the OVERWHELMING evidence showing Nature and the Sun has the most significant influence on temperature and thus life on Earth. Man is not to blame for the 4.5 billion years the Earth was uninhabitable so why do Alarmists like yourself jump to the conclusion that we are somehow to blame for the temperature fluctuations over the past 100 years?
