The Environment
Well I signed up so I suppose I had better blather on about ‘The Environment’, it sounds like some English Language project that you’d be given on returning to junior school after the summer holidays.
If we are considering the environment on a planetary scale then there appear to be huge problems, and on the most basic level they seem to be ‘what is it?’ and ‘what is it we want it to be?’, until you can answer these fundamental questions how much serious consideration should we be giving to attempting to tweak it? In general, the consensus on the science used to ‘measure’ what it is now and calculate the changes that, some suggest, need to be made appears to be eroding, in detail, every project on a significant scale is questioned; the underlying science, the social impact, the financial impact, the effect on wildlife habitat, the unabashed ‘not in my back yard’ objectors, the hectoring approach of many ‘environmentalists’, the contemporary ‘China Syndrome’ (what’s the point in anything we do when the Chinese are opening a new coal fired power station every week?) and many, many others. I would be the first to admit that I’m not the most informed guy when the topic is environmental issues so there may well be many others making significant contribution in this field but the characters that do come to my attention are woefully lacking in credibility, even after receiving part share of a Nobel Prize, in fact I would go as far as to say that the award diminishes the Nobel Foundation. Al Gore and the other talking head that comes to mind, Zac Goldsmith, appear to have ambiguous credentials in this field with both having business and political agendas which appear to be incompatible with an altruistic approach to global environmental reform.
From my limited knowledge of such things I would like to offer a couple of areas which seem to me to highlight our lack of certainty in dealing with the environment at a planetary scale. I read recently, in New Scientist I think, of a number of ocean seeding projects, some using iron compounds and others urea. Just the trials would require thousands of tonnes of material being dumped into the sea with the aim of initiating plankton blooms as a means to capture CO2 which would then be sequestered to the ocean floor when the bloom dies back. The best science we seem to have available at this time suggests that projects on this sort of scale are required to address the problems we face yet with this project, as with many others, there is little agreement that the, not fully understood, mechanism that is going to be manipulated is an effective method for sequestering CO2. Others have postulated that the whole affair is no more than an attempt to become a player in the carbon trading market. Yet it would appear that whatever sanction is required has been obtained and the trials will go ahead.
Clathrate hydrates is a term that I was blissfully unaware of until a few months ago, can’t remember where I heard about this one. These ice structures can contain various gases, one of which is methane and are found on deep ocean floors and permafrost. There is an inherent dichotomy here on a couple of levels; methane is a possible future energy source but also a greenhouse gas; the energy companies want to extract the methane from these hydrates which will inevitably require disturbing the structures and the concomitant risk of uncontrolled release of methane in significant quantities but these structures are also susceptible to disturbance by natural phenomena, particularly those in the permafrost due to global warming, which would once again result in uncontrolled release. Is this a reason to go ahead with the extraction as a cleanup exercise and development of an energy source or leave well alone and hope for the best? If the energy companies tell us that they have an engineering solution that would ensure no uncontrolled release, should we believe them?
Much of the above appears to be a mandate to do nothing yet the bulk of the science leads many to the conclusion that doing nothing is not an option commensurate with sustaining the environment, in the condition that we recognise today, over the long term. We seem to be rushing headlong to ‘solutions’ with no more than a vague grasp of the problem; we must stop any funding of piecemeal solutions to localised elements of a global issue and commit it instead to researching the totality of the problem whilst rebuilding the consensus around the results of such research by giving a platform to the scientists who undertake and understand the research. I acknowledge that this is no mean feat in communication terms as scientists are often not the most eloquent or charismatic of communicators and will be required to function effectively with scientists, politicians, businessmen and the general public, yet they are out there and must be found. I’m not proposing global government by a scientific elite, I rejoice in such democracy as we have and expect to continue to enjoy the right to cast my vote once every 4-5 years for whichever bunch of self-servers seems least obnoxious at the time, so there must remain political oversight but this must be of a form which requires the politicos to fully explain why, if they have chosen not to follow recommendations that have been forthcoming from environmental research which they have ensured has received an unbiased airing in the public domain.
