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…

More of Greenland's ice melted in the summers of 2000-2019 than in the ones between 1979-1999.   Some data: Links National Snow and Ice Data Center and the obligatory other links...

A small series of posts over the next week or so on the concept of "Type 1". These will be People, Planet and Challenges. Why? Simply put, my recent experience of public discourse and political debate in Australia (and those seeking public office) suggests we need to look closely for genuine intellectual honesty, strategic vision and coherent world views that can…

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…

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…

The. First. Time. Ever. Bueller? 411 Peak carbon dioxide levels surpass 411 parts per million for May Carbon dioxide levels measured at NOAA’s Mauna Loa Atmospheric Baseline Observatory exceeded 411 parts per million in May, the highest monthly average ever recorded, scientists from Scripps Institution of Oceanography at the University of California San Diego and NOAA announced in June. Also...…
