In her letter on lab - grown meat, Ingrid Newkirk makes a falsecomparison between eating meat and using tobacco, when she says that meat eaters, «like smokers trying to quit tobacco, find it very hard to give up the stuff» (24 September, p 39).
Anyway it is a falsecomparison to compare old temperatures with new temperatures when asking «wht should we do» you need to compare «our solution» with «their solution» If you are advocating a political strategy you need to accept current proposed strategies will probably still result in the majority of the global warming predicted in the ordinary scenario (if not all of it — a point which I can argue if you like).
