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.

'Freak Weather': A Thing of the Past or A Thing of the Future?
John Vidal opines that recent events confirms that 'there is no such thing as freak weather' (https://www.theguardian.com/commentisfree/2022/dec/29/no-such-thing-freak-weather-2023-storm-elliott). What he seems to mean by this, is that the global temperature has already changed so much, that 'freak weather' events have now become the norm. It has long been known that the human-mediated release of 'greenhouse gases' will elevate mean global temperature, as more of the sun's energy is trapped. In spite of this and repeated warnings, our species has continued pumping out carbon dioxide and methane. This adds power in the planet's distorted weather systems. These changes will lead to more storms, heatwaves, cold snaps (as air rushes into more equatorial regions from polar locations), droughts and flooding (as more water evaporates into the atmosphere before falling as rain/snow). The intensity of these events will also increase. This, seems to Vidal, to be highly predictable. Weather events were formerly labelled as 'freak', when they only occurred very occasionally. That was certainly not the case in 2022. Vidal predicts that 2023 will be worse. It's never been more urgent to stop adding to our climate problems and to develop ways of dealing with the established norm of intense weather events.
