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.

Even Worse Than Coal?
Fossil fuel enthusiasts have pushed the line that Liquified Natural Gas (LNG) provides a 'bridge' as we transition from using coal to renewables. Unfortunately, detailed studies show that LNG actually generates circa 33% more 'greenhouse gas' than 'dirty, old coal'. Most LNG for export is produced in the US (often by fracking, a process that can liberate some methane to the atmosphere). Emissions are also generated by using energy to liquidize the gas. Exporting LNG to Europe and Asia, by marine tankers, adds yet more 'greenhouse gas' emissions. And, that's before the methane (itself a very potent 'greenhouse gas', if it escapes) has even been burned (https://www.theguardian.com/us-news/2024/oct/04/exported-liquefied-natural-gas-coal-study). One could even add further to the LNG 'greenhouse gas' emissions balance sheet. Emissions are also generated by building the shipping and the terminals involved in the process. It's not the kind of 'bridge' that we ought to even consider. The sooner LNG is phased out, the better!
