Been there, done that. You don't know what classes you're going to have from term to term, and thus what your income will be.

Strange she would publicly take such unorthodox positions with such tenuous status.

EDIT

Unsurprisingly, they’re a little upset that the University of Victoria decided not to renew Crockford’s position, which came with no salary, involved no teaching, and was mostly symbolic. However, the position did give Crockford access to the library and a sliver of credibility. The appearance that she was a serious enough academic to be endorsed by a real university is something she could use to try and get research grants, dovetailing with deniers’ parasitic need to boost their own credibility by attaching themselves to legitimate aspects of academia.

CFACT referred to the move as an “ideological purge,” and an op-ed in the Canadian Financial Post quoted Crockford calling it “an academic hanging without a trial.” Valerie Richardson opened her totally-not-biased coverage in the Washington Times with the lede “Nobody has done more to sink the claim that climate change is endangering polar bears than zoologist Susan Crockford — and she may have paid for it with her job.”

But an unpaid, non-teaching adjunct position is hardly a job. While it is true that nobody has done more to attack the claim that polar bears need cold, Crockford sure hasn’t sunk it.

Deniers will of course try and spin this into a free speech on campus issue, even though it obviously isn’t. Crockford wasn’t being paid by the university and is still perfectly free to continue doing her blog-level polar bear population science. But she’ll have to soldier on without her U-Vic affiliation, which is a major loss to her effort to seed denial propaganda, and the real reason for all the commotion in climate denial land. For all their bluster about how liberal colleges are the bane of human existence, deniers are desperate for the credibility that comes with a university affiliation.

Nice to know others are aware of this. Nobody has really come up with an explanation of her motives, other than making a small amount of money from the climate change deniers who use her work.
