May 2020 hit a record high, 417 parts per million (ppm) carbon dioxide as measured at the Mauna Loa Observatory, which has continually measured CO2 in the atmosphere since 1958. The reading of 417 ppm is likely the highest it has ever been in the history of humans on Earth. On top of that, it is likely the highest concentration…

All truth passes through three stages. First, it is ridiculed. Second, it is violently opposed. Third, it is accepted as being self-evident.

Outstanding work by the ABC team abcnews , storylab, the Monash Climate Change Communication Research Hub and the ARC Centre of Excellence for Climate Extremes to visualise climate change over time and make the global, very personal.  From top to bottom, these stripes use Bureau of Meteorology data to show how temperatures have changed in Australia since 1910. The colours indicate how much…

What is the argument against reason and logic? The latest UN Environment Programme (UNEP) emissions gap report suggests that unless the world begins to rapidly reduce greenhouse gas emissions the 1.5C goal of the Paris Agreement “will slip out of reach,” The figure below, adapted from one created by CICERO’s Dr Robbie Andrews, shows emission trajectories to limit warming to…

Consider, once again the current political discourse and *major* issues in the news. Consider the *major* policy announcements of political parties prior to an upcoming Australian Federal Election. Then take a moment to ponder this. The highest weekly average CO2 ever measured at Mauna Loa: 412.4 ppm, almost 4 ppm above same time last year. February seems on its way…

X-Roads

Cross-Roads. After attending a 2016 public lecture at Lab-14 co-hosted by the Australian-German Climate and Energy College, the Climate Institute and the Melbourne Sustainable Society Institute, I mused [pessimistically] that 1.5 or 2 degrees no longer seemed a choice. The IPCC special report on the impacts of global warming of 1.5 °C has just been released today. In essence, zero net emissions by…
