A recent report suggests that we are more than half way towards the 2 degrees Celsius elevation in global temperatures where climate changes becomes truly dangerous (http://www.bbc.co.uk/news/science-environment-34763036). The first thing to note about this is that the 2 degree 'maximum' is entirely arbitrary and there is no real binding evidence that lesser increases will not produce catastrophic (and irreversible?) changes. It is remarkable, given the accumulated evidence that people still argue that humans can carry on doing what they are doing to increase levels of greenhouse gases. Apparently (in spite of declining prices), Middle East oil extraction has hardly changed.
This blog may help people explore some of the 'hidden' issues involved in certain media treatments of environmental and scientific issues. Using personal digital images, it's also intended to emphasise seasonal (and other) changes in natural history of the Swansea (South Wales) area. The material should help participants in field-based modules and people generally interested in the natural world. The views are wholly those of the author.
