Who would you listen to when it comes to climate change?

I see Lewes’ very own Don Quixote, Brian Beck, is tilting at windmills again.

At the meeting to which Mr Beck refers (letters, October 24) the speaker explained that burning more than 20 percent of known fossil fuel reserves would produce catastrophic climate change.

Since the remaining 80 percent cannot be used, they are thus more or less worthless, and it would be unwise to invest in any company that claims them as assets. Interestingly, the same point was made a few days later by Mr Mark Carney.

Now the question is: from whom should one take financial advice? From Mr Beck ( a retired engineer with a bee in his bonnet) or from Mark Carney (the Governor of the Bank of England)?
