Wren-Lewis: "This really is like blaming scientists for not warning enough about climate change."
Wren-Lewis implies that it is *wrong* to blame climate scientists for not being politically engaged.
But that is indeed largely why we are in a climate crisis: the blame lies largely with climate scientists.
The problem is the same problem that manifests with academics generally. They are closeted in their seminars and conferences; they are like anoraks and nerds who prefer to stay in their basements playing video games rather than getting their hands dirty through involvement with the real world with its dirty business (e.g. politics). That is: prefer to stay in their comfort zones.
The attitude is: Let's wait til all the fighting blows over, then, when things have calmed down and we can feel safe again, we'll stick our heads above the parapet again.
All that academics really care about is being feted by others, e.g. politicians, through being invited to expound their *professorial* expertise.
They always want to run away from a fight.
But their running away only exacerbates the misery (e.g. austerity) for citizens. Academics who are both intellectual giants *and* political fighters (e.g. Noam Chomsky) are very rare.
Economic experts are happy to *advise* Corbyn (because that boosts their own profile), but they don't want to be seen as *endorsing* any politician because that would bring them too close to the heat of the battleground.
And they spin that detachment from the fight as a virtue ("neutrality"), just like the BBC spins its 'impartiality' between climate science and sceptics as a virtue (but is actually journalistic cowardice).
