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.

Global Heating May Accelerate?
El Nino is a naturally occurring weather pattern, typically associated with world-wide increases in heat. Its converse, La Nina, is a cooling pattern. From 2020 to 2022, the planet experienced an exceptionally long La Nina event. The UN's World Meteorological Organization (WMO) notes, that the last 8 years have been the 'warmest' on record. This happened in spite of La Nina's cooling effects, for at least half that period. The WMO consequently expects global heating to accelerate (https://www.theguardian.com/environment/2023/may/03/un-warns-heat-records-could-be-broken-as-chance-of-el-nino-rises). The last El Nino event was in 2018. The WMO estimates the chances of this weather pattern developing by the ends of July and September 2023, as being 60 and 80% respectively. When El Nino comes round again, the 'brakes will be taken off' climate change. New spikes of global heating appear to be more-or-less inevitable.
