Would that be a career funded to prove climate change ?"
This may well be true, to an extent, but it is really a distraction. Scientists have to secure funding, like everyone else, and that may occasionally lead to trumped-up claims of future success, and of course research trends. But in the end the overall trend is to the truth, not to a conspiracy, and if the results don't support a conclusion then eventually even the most corrupt scientist will be obliged to admit that.
Besides which, this report if anything should be a bonus to those people who are against the concept of (man-made, which is the only remaining debatable issue) climate change. An underestimated natural source of emissions? Should be a boon to people on the other side of the debate.
