As someone who understands this process, findings like this lend tremendous credibility to the scientific community, and yes, boost my confidence in the work they're doing and the integrity of the published results. It's what makes science the best method we know of for understanding reality.
I'm not arguing the validity of the results from the research. But, just for arguments sake, lets play with the idea that the researchers published a report that established that they had overestimated the temperature differences by 50%. Would you still, right now, be compelled to say this lends tremendous credibility to the scientific community? Would it boost your confidence in the work they're doing? Would the integrity of the published results be less than previous studies have provided?
Before jumping to the conclusion that I'm a denier...
I have been convinced that the Earth is in a warming phase.
I have been convinced that humans should reduce the output of greenhouse gases.
I have also been convinced that most of the carbon credit and associated businesses that have been started to support it are, shall we say, powered by less then altruistic motives.
I have been convinced that some politicians and business leaders are making significant amounts of money or adding to their power and influence by evangelizing the push to blame all global warming on human influence.
I don't take the extreme position that we are the only cause. Some small amount of climate change can be attributed to human activity. And, we need to get off carbon based energy production. And we need to be better stewards of all of our natural resources. We are not doing a very good job of convincing the majority of the population. Part of the problem is that even though we own the information outlets, we are using failing methods to get our message across. Stop tell everyone that "deniers' are slack-jawed mouth-breathers. All of us need to stop being bullies that act like pussies when we don't get our way. Basically, we need to stop being jackasses to anyone that asks a question or expresses a difference of opinion and we might actually start to make some headway.
