CO2 concentrations at Mauna Loa continue the march... Weather is NOT Climate, most certainly, but this is worthy of note. For the first time temperatures of 40°C have been forecast in the UK and the Met Office has issued the first ever Red warning for exceptional heat.MET Office - United Kingdom UK Temperatures since 1970 The Keeling Curve is a…
The Working Group I contribution to the Sixth Assessment Report, Climate Change 2021: The Physical Science Basis is now out. The report addresses the most up-to-date physical understanding of the climate system and climate change, bringing together the latest advances in climate science, and combining multiple lines of evidence from paleoclimate, observations, process understanding, and global and regional climate simulations.

The mean carbon dioxide measured at Mauna Loa Observatory, Hawaii in June 2021 was 418.94ppm. 418.94ppm If I am not mistaken, this is the highest concentration recorded since humans have been on earth? At least it is comforting to know that such existential issues are front-of-mind for our political leaders. You know, "follow-the-science" and all that... Source: NOAA 2021 I…
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…
Sitting in rural Victoria, sky obscured by bushfire smoke, I am reminded that I have said [and written] many times, that climate and energy transitions are the greatest challenges of our [and our children's children] time. It would appear most of the Federal Government disagrees with me. What are the arguments against a more sustainable future? What are the arguments…
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…
