A more relevant question is: if climate change is a real problem, and if the problem is on the scale which some allege, is there anything effective we can do about it, and if so, what?
IF there is a real problem, we need real solutions. 'Gesture Politics', posturing and Greenwash are worse than useless because they not only waste time, money and piss off people like me, they delude the naive and the technologically illiterate into thinking that "It's all right, something is being done, everything's fine".
Given the scale of the alleged threat, waving a few windmills, or paying me 50p per unit (£1,800 a year) to generate solar power at times when no-one needs it, will achieve nothing except make some people feel better - about as useless as sacrificing a goat in order to stop God from being angry with us and inflicting plagues on us.
A more practical step might be to anticipate possible rises in sea levels and to revise the standard tables of probable maximum wind speeds, rainfall and temperature extremes as used by civil engineers.
King Canute did not stop the tide, nor did he try anything so futile, not even bothering to build a barrier. Neither did he drown. Being a sensible bloke he recognised the situation, accepted the inevitable and did the most practical thing - he shifted his throne higher up the beach.
