CLIMATE 4 November 2025 - The Atlantic Meridional Overturning Circulation (AMOC) is already at its weakest in over 1,600 years and is 70% likely to shut down by 2050 under high emissions (25% under low). This system, which transports heat toward Europe, is being disrupted as global warming and meltwater from Greenland reduce the water's density, inhibiting the circulation's engine. A complete shutdown of the AMOC (possible within decades) would cause an extreme climate crisis by triggering a sudden cooling of 5°C to 15°C in Europe, accelerating sea level rise up to 70 cms along the North American East Coast, and causing severe global weather chaos, including catastrophic droughts in the tropics. While cooling Europe it would accelerate global warming in other regions by reducing the ocean's ability to absorb carbon dioxide. See: https://www.nature.com/articles/s41467-025-64268-3

CLIMATE 8 July 2025 - 89 year-old eco warrior Prof David Suzuki has come out saying the war for the planet is lost. He is not a climate scientist but this is a big call from a titan of ecological advocacy and he is basing it most likely on recent news that humanity has now breached seven of the nine planetary boundaries tracked by the Stockholm Resilience Institute He said in an interview with iPolitics: “It’s too late.  We have failed to shift the narrative and we are still caught up in the same legal, economic and political systems.  For me, what we’ve got to do now is hunker down.” Source: https://www.ipolitics.ca/2025/07/02/its-too-late-david-suzuki-says-the-fight-against-climate-change-is-lost/

CLIMATE 4 April 2025 - Well, this is getting boring (at least if it wasn't so damned important). Australia has experienced its hottest 12-month period on record, ending with its hottest March on record, with last month seeing temperatures 2.41C above average, the Bureau of Meteorology has confirmed.  The bureau said its data going back to 1910 showed the 12 months ending in March 2025 averaged 1.61C above average – the hottest of any 12-month period, beating the previous 1.51C mark set from January to December 2019.  The 2.41C record for March easily beat the previous 2.03C mark set in 2019.  March also had the hottest overnight temperatures for that month, at 2.53C above the 30-year average between 1961 and 1990. March 2025 beat the previous 2.11C mark set in 2016.  What’s more, Australia just had its warmest spring-summer on record in 2024-25, with the six months from September to…
