I am very impressed with Advice for a young climate blogger on the Real Climate blog – one of the best sources on its topic. The advice extends well beyond climate blogging. For example:
Don’t defame people. This should go without saying, but trivially accusing scientists of dishonesty, theft, academic malpractice and fraud pretty much rules you out of serious conversation. Instead it will serve mainly to marginalize you – though you may gain a devoted following among a specific subset. Don’t be surprised if as a consequence other people start to react negatively to your comments.
Correct mistakes. Again, it should go without saying that maintaining integrity requires that errors of fact be corrected as soon as possible.
Realize that although you speak for yourself, if you take mainstream positions, you will be perceived as speaking for the whole climate science community. Don’t therefore criticize unnamed ‘scientists’ in general when you mean to be specific, and don’t assume that the context in which you are speaking is immediately obvious to casual readers.
Avoid using language that can easily be misquoted. This is hard.
Don’t use any WWII metaphors. Ever. This just makes it too easy for people to ratchet up the rhetoric and faux outrage. However strongly you hold your views, the appropriateness of these images is always a hard sell, and you will not be given any time in which to make your pitch. This is therefore almost always counter-productive. This can be extended to any kind of Manichean language.
There is a lot more, all good. And yes, there are times I have needed such advice.
