So they ended up in another industry after trying to publish and/or do research. Does this stop them from emailing Black?
I could think of many reasons that they didnt email Black, such as they didnt know they could or should. This leads right into your last paragraph:
He, very publicly, asked for any evidence to confirm that suppression etc had taken place.
I asked you what steps he had taken.
"Very publicly" is both very vague and includes a value judgement.
I suppose now I have to ask you a more pointed question.
What did he do,
specifically, in order to ensure that his investigation was unbiased and would lead to the facts on the issue?
What individuals did he contact? What organizations did he contact? What leads did he follow?
If you do not know the answer to those questions, then you do not know the value of his reporting. I certainly do not know the answer to that and am asking you, who very publicly suggests that his reporting did have value, for the answer.
From what I have seen of this mans work, it does not appear that he even attempts to perform
investigative reporting. It appears to me that he instead attempts to
generate news, such as when he mailed the signers of that Canadian letter which called for their government to investigate the utility of its climate change program.
The article was not "reporting" on the utility of government programs meant to address the issue, yet the people he contacted were all from a list specifically concerned about it. His "investigation" drew from this list for what would be hoped to simply be arbitrary reasons, rather than the more logical reason that he knew the replies would be all over the place given how out of context it was. Thats not investigative reporting. Thats news manufacturing.
Asking for evidence to support claims is a normal situation, just see my next post.
I did see your next several posts, but still don't see how "asking" is defined.
Who did he ask? How did he ask? Did he give assurances of anonymity? What legwork did he do?
