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.

"Please Sir. Can I Have Less?"
A report in the journal Bioscience, reveals that many key indicators of the global climate crisis are worsening. The indicators appear to be either approaching or have already exceeded 'tipping points' (situations, where it has become almost impossible to reverse the trend) as our planet heats up. A major lesson of the Covid19 pandemic seems to be that, even with substantially frozen transportation and consumption, reductions are insufficient to counter the climate crisis (https://www.theguardian.com/environment/2021/jul/27/global-heating-critical-measures-tipping-point-study). The report notes that over half the planetary vital signs are currently heading in the wrong direction. These include atmospheric 'greenhouse gas' concentrations, heat content of the oceans and the mass of ice. The reduction of activities over the Covid19 pandemic actually resulted in negligible reductions in carbon dioxide release. Methane and nitrous oxide (other 'greenhouse gases') both set new year-to-date records in 2020 and 2021. It is notable that ruminant livestock (largely cattle and sheep) now exceeds 4 billion. These methane-emitters, have a biomass that is greater than all humans and wild animals (I think they mean Mammals) combined. Most people, even those concerned about the climate crisis, fail to understand the magnitude of the required changes needed to slow or reverse this planetary heating. This will be a very difficult 'sell'.

First we have to want to change…. We obviously don’t. Even with less flights and cars etc during lock down nothing has changed. To me that just says we are truly fu(ked. People expect meat everyday = we are fu(ked ….. people expect to drive outsized cars capable of driving across the Sahara just to go shopping and drop the kids at school = we are fu(ked ….. people expect to go on flights to sit next to a swimming pool in some gawd awful hotel in the sun = we are fu(ked…… I could go on but frankly it’s useless.
