Green debate revolves around use of convenient facts
There have been the odd letters (meaning occasional but sometimes odd as well...) about climate change but one thing puzzles me and perhaps a chemist or physicist can help me – and translate the emotion so often perpetrated by the zealots!
If global warming is happening and the polar ice caps are melting, this should mean the salinity in seas decreases as dramatically as all that extra fresh water and greater rainfall from rising temperatures are added. Salt reduces the heating point of water therefore increases 'thermal expansion' caused by heat. Therefore is the opposite happening and reduced sea salt levels offsetting the other? How many millimetres has the sea level risen in say the last fifty years?
I believe in climate change. It's been happening since climate and planet existed. I believe mankind impacts climate change – both negatively and positively but also that it is arrogant for us to think we are so influential on it compared with natural events. A volcanic eruption has far more impact than any coal-fired power station. We talk of rain forests being destroyed but we don't talk about the carbon-absorbing reforestation happening in many places – like the UK which now has its greatest tree cover since before King Henry VIII we are told. I heard that the planet is about 20% greener than it was – but how such statistic is collated and against what it is compared I don't know but it does follow though – the more CO2 then the more plants as that is their 'food'!
We are oft presented with the 'facts' but there is so much bias it is untrue – the same as the 'facts' in the early 1980s when the fear then was for another ice age. Facts which are inconvenient are avoided and those which endorse a prejudice promoted and by scientists who should know better.

It is a great shame that the debate cannot be better conducted for everyone's benefit and those exploiting present fears for their personal benefit coming clean about that too, whatever arm of alternative technology, charity or government organisation paying them handsomely or subsidising their product or calling.
Yes, we should recycle our valuable resources and should always have been doing so as it is wasteful not to do so, as well as recognising that putting things in the appropriate recycling bins is not careful use of commodities in this throw-away society.
We should use energy wisely and insulate better and yes, look at alternative energy but one thing so many overlook is that the scarcest resource of all is cash and it should be spent wisely and efficiently. Spending £100,000 on a government/ charitable green energy project to 'save' £1,000 pa of electricity is not a good spend compared to how the money could really be directed for the betterment of the planet and its inhabitants for now and the future, if we truly believe in doing the most constructive thing towards that goal. Wasting cash so wantonly is worse than wasting a little bit of energy – private individuals should consider the same argument when considering the cost and return of their own alternative energy producing investments and if it is just to go green, giving money under Gift Aid towards research charities is likely to be the best use of the money!
