Eastern Australia January 2020 - burning and fires - the influence of climate change

NSW Rural Fire Service fire ground map

Summer in Australia each year brings the bush fire season with hot weather, low rainfall and high humidity matched with regular electrical storms with more lightning than precipitation. Over meteorological history, the peak period in Australia has tended to be around late January to February for bush fires. Increasingly however this high risk timeframe has come earlier and now commences at the end of Autumn in the preceding year. Temperatures have been hotter at earlier points in time and rainfall has become less dispersed over the land and more concentrated within the period when it does fall. Droughts or floods are the obvious, extreme result.

This measure of impact is the actual influence of climate change in its earliest form at around 1.3C to 1.4C temperature increase. Climate change does not mean that the planet will suddenly be a tropical hothouse as those whom deny human-induced change constantly state, but rather the extremities with weather are now amplified many times over.  This provides an early window into how severe the changes will be if the current inadequate or lack of action continues.
