Pointing Fingers
I think it is human nature to look for someone or something to blame for tragic events. I do believe that there is a climate change going on, but Occam's razor suggests using the least complicated answer to the questions. As you pointed out, some things that are being seen as being a cause of global warming are problems that can be explained by other reasons.
Another example of quick judgement is the series of weird violent crimes that are quickly explained as a drug problem, usually bath salts. The blame is made before any actual testing and it tend to be used to support an agenda but not anything that is scientifically determined.
In some third world, er developing countries, people go on witch hunts because there seems to be a lot of bad luck happening. Sometimes those witch hunts find people who can not defend themselves and they are injured or killed to stop a run of bad luck.
As for the convicted scientists, I hope that this verdict is appealed and overturned. The L'Aquila earthquake event was tragic, but the state of scientific ability to predict earthquakes is limited to a longer time span and not a pin point and immediate warning.
