While not an ANZ specific topic, I just want to reference a post of mine in another TMC thread since the issue came up in this forum. It may be of interest to many. In the thread Australia government supports for EVs, I referenced research that the rate of atmospheric CO2 change is 50-100x faster than it has ever been over the past 800k years. Fo those interested, I was motivated to pull out the source CO2 data going back to 800k BC and analyse it myself. The results confirmed that this statement is indeed true - in recent years the rate of CO2 increase is around 50x faster that it has ever been over the past 800k years, with spikes above that. My results are posted in this TMC thread: Climate Change / Global Warming Discussion What’s also interesting is that this acceleration started in the late 1700s, coincidental with the commencement of the industrial revolution. Prior to that the CO2 cycles up and down almost always lay in the range of -46 to +49 parts per billion per annum (ppb/pa). That sets the definition of “natural” variation, and anything outside that is demonstrably not “natural”. We are now seeing CO2 increase at annual rates of 3000 ppb/pa and higher. Be very, very concerned.
