Most people don’t know what complex systems (the word ‘complex’ is important) are, despite the fact that everyone one is enmeshed in several such complex systems every minute of the day and night. One such complex system is language, which we use more or less all the time, except when we sleep, and even then,…

By Garret Barnwell The taps will run dry, fires will rage, new diseases will emerge and the weather will run an increasingly unpredictable gambit. This is what you likely have heard of the future in the era of climate change. But did you know the climate change and environmental destruction has a profound impact on…

We are in Porto, Portugal, for an interdisciplinary international conference, and already we are impressed by the beauty of this old city. As usual, because I find seats on a passenger jet too uncomfortable to sleep, I used the time to catch up on some movies, including I, Tonya, with Margot Robbie’s Oscar-quality performance in…

A number of things have struck me since we arrived in Europe to attend a number of conferences, travelling from Ghent in Belgium through Munich in Germany to beautiful Venice in the Veneto of Italy, and they do not augur well for the future of human society or the planet. These range from observations in…

After multiple delays, and the building up of a twisted reality television-like suspense, Donald Trump has finally announced that he will take America out of the Paris Climate Agreement. Among all the fluster of his presidency, this may be one of Trump’s most consequential decisions, and the one with the most long-lasting negative, if not…

Most readers’ gut reaction to the question, above, would probably be something like: ‘Yes, of course!’ But please consider that the question is not whether humans are, on occasion, capable of rational behaviour.

These include the fact that he has, on several occasions, shown himself to have a questionable attitude towards women, and generally towards a variety of minority groups in America, at a time…

One of the most revealing threads running through Canadian investigative journalist and tireless anti-capitalism activist, Naomi Klein’s rivetting book, This Changes Everything: Capitalism vs. the Climate (Alfred A. Knopf, 2014), concerns what she terms the “new climate warriors”, or in one word, “Blockadia”. This unlikely-sounding word names a movement which has arisen in the shape…

We spend a large portion of our lives moving about, a significant percentage of our income too, and it directly affects the future of our planet. So how come we don’t think of transportation as a fundamental life issue in the same way we consider our personal health, financial stability and self-realisation? More than 17%…

By Penny-Jane Cooke The last quarter of 2015 saw five out of the nine provinces — KwaZulu-Natal, Mpumalanga, Limpopo, the North West, including the breadbasket of the country, the Free State — declared as water disaster areas and by extension disaster areas for agriculture. Somehow, the linkages between how the intensive water use for coal-fired…
