Why are humans so arrogant? How long have we as a race truly been documenting historical temperature data? For us to look at 100 years worth of data and say that the Globe is warming seems quite arrogant of today's society given the age of the earth. Perhaps the mean temp of the earth has fluctuated up and down by as much as ten degrees for the last hundred million years. How do we know that the earth is now warmer then it ever has been? Perhaps we have been in a global cooling for the past 100 years and just now we're getting back to normal. How can we claim responsibility? Do we really think that we can effect the earth's climate in such a short amount of time?
