The Nobel Prize in Physics has gone to three scientists who sought to predict the long-term evolution of a complex system such as the climate by modelling variables -- weather, human actions -- that create disorder within those systems.

This crime has been going on for decades. We see its effects in the horrific heat and wildfires unfolding this summer in the American West; in the megastorms that were so numerous in 2020 that scientists ran out of names for them; in the global projections that sea levels are set to rise by at least 20 feet (6 metres).

Today is Earth Day, which should provide us with an opportunity to pause and confront the awful predicament humanity faces. We eat microplastics, breathe pollution and watch other life-forms decline to extinction. We face intersecting poverty, health, climate and biodiversity crises. Our global predicament is that consumption by the wealthy is driving us towards planetary disaster, yet billions live in poverty and need to consume more to live well. In this cycle, any version of “success” only hastens catastrophe.

An astonishing global shift is under way: 127 countries have now stated that by mid-century their overall emissions of carbon dioxide will be zero. That includes the EU, US, and UK by 2050 – and China by 2060. Companies are enthusiastically signing up to similar “net zero” goals.
