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.

Fiddling Whilst the Planet Burns?
Robin McKie says there's no prospect of a 'magic bullet', to rescue the Earth from global heating (https://www.theguardian.com/environment/2023/jul/30/radical-ways-to-fix-the-earth-are-they-magic-bullets-or-just-band-aids). Capturing carbon emissions and storing them underground is difficult and much too slow. Carbon dioxide (for all its demonisation) makes up only a small percentage of the Earth's atmosphere. It's consequently difficult (and energetically demanding) to extract, even before converting it to a state, where it can be safely stored (perhaps in a disused oil well). Solar Radiation Modification (SRM), in contrast, tries to deflect the 'problem'. Suggestions here, include using giant orbiting mirrors or high atmospheric clouds of sulphate aerosols, to reflect sunlight back into space. SRM would, of course, simply leave the 'greenhouse gases' in place. Most climate scientists maintain that the only sensible and workable strategy, is to stop extracting and burning coal, oil and gas. Even if that was done (most unlikely in the present financial and political 'climate'), there would be no immediate effect on global heating.
