Sure, we have Google... but you haven't really given us much to go on. When I Google "ice age", I mainly get stuff like this:Do you not have google? This is the problem with folks wanting sources.
Why would it be dishonest? You gave a specific claim and referred to "some scientists"; if you weren't making this up, you got it from somewhere... where? And which scientists were you referring to when you said "some scientists"?ALL SOURSES ARE BIASED IN ONE WAY OR ANOTHER. NO SOURSE IS 100% CORRECT.
Using the reasoning behind wanting sources in the first place would imply that before the internet, nothing was true because it was not on the net.
It really is a big waste of time posting sources because they all have faults that can be challenged. But yet we ask for them anyway. Not exactly an honest request is it?
If anything, I think it's dishonest to make an appeal to authority - as you did in the OP - and then respond to questions about the nature of this authority by claiming that the authority doesn't matter.
If sources don't matter, then why did you bother to cite "some scientists" in your OP and not "some crank on Yahoo Answers"?
