I have worked with scientists as well (not in Arctic, thankfully). I know they are mostly motivated by the search for scientific truths. But here's the thing:
1- Most scientists know little more about climate change than the general public. Their field may be entirely unrelated. Yet, such scientists are often quoted.
I wouldn't say most because it seems to me that many areas studied by scientists are somehow related that part of their study includes a need to know about climate change, from archaeology to zoology. Naturally, there are fields that aren't connected, but where they are being quoted as experts, I've not seen. Most that I know, if they comment at all in a field not theirs, preface it with that admission.
2- Scientists are as susceptible to peer influences as anyone. If they hear a lot of respected scientists talk about climate change, they are inclined to accept it at face value (unless they are in the field).
And rightly so. "Respected" scientists are respected for good reason. They have no reason to disbelieve such a respected peer.
3- Scientists in some unrelated fields (say they study snake breeding habits, or hydrogen embrittlement on metals), may have access to more funds if they include some aspect of climate change in their studies, however marginally relevant it may be.
I can see how climate change could have an enormous impact snake breeding habits.
4- Scientists who have demonstrated a willingness to upset the status quo get fewer funds.
I'm sure that's so in some cases, but I'm sure the opposite is true, too. A scientist that goes against the grain and proves to be right reaps enormous rewards, from the Nobel to possibly saving millions of lives.
There are few scientists on either side willing to wreck their careers. Most compromise. (The article you provided was rather interesting, as it points out Obama's willingness to use the justice department and criminal charges to go after people who oppose or slow down his programs. But that's another kettle of fish.)
If compromise is the norm because the powers that be will ruin their career, it's not the scientists' fault. We should encourage legitimate dissent and separate it from truly wing-nut nonsense, if possible, but then again, before their theories proved true, many were proclaimed everything from heretics to insane.
Hard to say how much Obama's knowledge or interest (if any) about this case was. Will have to research the end of the story.
