Perhaps those wishing to comment on climate science would like to, to put it politely, actually read what the scientists say before commenting. Just because you have an opinion does not make it a reality, and it is highly discourteous to rubbish the work of scientists without even reading or understanding it. These people are experts for a reason: They have a detailed understanding of the subject and suitable training in the field.
That doesn't make them right, but it does mean that, unless you are also an expert in the subject and have read extensively on that subject, they're more likely to be right than you.
