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.

Hot News From the Hot Spring?
Cyanobacteria, from hot volcanic springs on the Italian island of Vulcano, have been shown 'eat' carbon dioxide 'astonishingly quickly' (https://www.theguardian.com/environment/2023/apr/19/volcanic-microbe-eats-co2-astonishingly-quickly-say-scientists). All cyanobacteria are, of course, photosynthetic. Their work, in much geological times, probably pumped the oxygen into the ancient atmosphere. Extremophil cyanobacteria, as found in hot springs, might well be remnants of ancient bacterial populations. It will be interesting to establish whether these, recently studied cyanobacteria, are really much more efficient at removing carbon dioxide than commoner species. Afterall, photosynthesis is photosynthesis! If they really are more efficient, it may indeed, be possible to use them to remove excess carbon dioxide from the current atmosphere.
