Global warming and its disastrous consequences are now truly with us since the second part of 2019. At the moment a change in the weather has given parts of the country a respite from the raging fires, some of which are still burning or smoldering, waiting for another warm spell to flare up. The danger zones include the Australian Capital Territory, from where these lines are written. To date 18.6 million hectares(186,000 square kilometers) were burnt, including native forests, native animals, homesteads and towns, and 24 people died. The firestorms betray harbingers of a planetary future, or a lack of such,under ever rising temperatures and extreme weather events inherent in fossil fuel driven global warming.
Global heating
As the atmospheric concentration of the well-mixed greenhouse gases rise (CO2>411.76 ppm;CH4>1870.5 ppb; N2O>333 ppb plus trace greenhouse gases) land temperatures soar (NASA global sea-land mean of1.05C since 1880). According to Berkeley Earth global land temperatures have increased by 1.5C over the past 250 years and mean Arctic temperatures have risen by 2.5C to 3.0C between 1900 and 2017.According to NASA:
