To be a catalyst is the ambition most appropriate for those who see the world as being in constant change, and who, without thinking that they control it, wish to influence its direction - Theodore Zeldin

A Mundane Comedy is Dominic Kelleher's new book, which will be published in early 2020. We will be publishing extracts on this site and across social media during the last quarter of 2019. Please feel free to contact us with any questions about the book.

What's Changing? - Climate



Please see below recent climate-related change, including key developments regarding the UN Sustainable Development Goal 13 - Climate Action.

Imagine a ship that is sinking and needs all the available power to run the pumps to drain out the rising waters. The first class passengers refuse to cooperate because they feel hot and want to use the air-conditioner and other electrical appliances. The second-class passengers spend all their time trying to be upgraded to first-class status. The boat sinks and the passengers all drown. That is where the present approach to climate change is leading - Buddhist monk Matthieu Ricard

  • Richer nations tend to politicise the climate change while poorer nations more often present it as a problem of international concern, according to a study published in the journal Global Environmental Change. Researchers analysed more than 37,000 news articles from 45 countries and territories using computer algorithms and found that the strongest predictor of how a given country’s press will cover climate change is Gross Domestic Product per capita. In short: the way a country’s media reports on global warming is based on the resources available to combat it.

  • Scientists tracked in 2019 an unprecedented number of fires burning north of the Arctic Circle in Greenland, Russia, Canada, and Alaska after a record summer heatwave. By one estimate, the fires released more carbon dioxide than Sweden's entire annual emissions in one month alone. This problem increases the risk that politically disruptive effects of climate change – like mass migrations or geopolitical competition for ice-free Arctic sea lanes and undersea resources – will arrive (much) more quickly than expected, noted GZEROMedia.

  • Chatham House examined the increasingly urgent narrative surrounding climate change and the role of the corporate sector in helping avert the climate crisis. How, if at all, are strikes, protests and the new state of emergency reshaping consumer expectations, corporate strategy and public policy on environmental issues? What new business models and frameworks can private enterprises develop to help contribute to climate governance? And to what extent can businesses provide genuine leadership on climate change?
  • Compost may be a key part of the solution to addressing climate change, but large-scale collection of food scraps, yard trimmings, and even human bodies poses a huge logistical challenge. Cities like Seoul, South Korea, which recycles 95% of its food waste, are proving it’s possible, while sites in Sweden, California, and New York are turning egg shells and carrot tops into biogas and saving money in the process.

  • It may be human nature to rejoice in sunshine and balmy breezes, but when the cause is climate change, days much hotter than the seasonal average can spark anxiety, too. Quartz asked scientists and philosophers about how to deal with this cognitive dissonance, and how to channel our emotions toward action.
  • The Little Ice Age is term that often refers to a moderately cold period in the 17th and 18th centuries that hit Europe especially hard. But it may have gone as late as the 19th century and began - or was at least triggered - in the 13th century. Either way, the Little Ice Age caused famines, sparked witch hunts, altered wars, toppled dynasties, and may show us what lies ahead with climate change, according to Quartz.
  • Students around the world have gone on climate strikes. Inspired by Greta Thunberg, a 16-year-old Swedish climate activist nominated for the Nobel Peace Prize, students in more than 100 countries have held massive school walkouts to protest climate inaction.

  • Glacier shrinkage, combined with melting of the polar ice caps, pose three main threats: raising sea levels; disrupting ocean current circulation and losing freshwater stores. The threat of the Greenland ice sheet slipping ever faster into the sea because of warmer summers was challenged in a scientific study.
