What Caused Austraias Disastrous Wildfires?

Abstract

Introduction- In the journal Physics Today of March 2020, David Cramer published an article on p. 26 with the title: “What Caused Australia’s Disastrous Wildfires? It Is Complicated” [1]. Our title does not have the word “complicated” because we don’t think it is that complicated and we intend to explain not only what caused the wildfires, but to explain also the peculiar asymmetric characteristics of the global warming. Bushfires are common in Australia, but this year the disaster was overwhelming - 11 million hectares burned, which is the size of the Australian state Virginia. Even Sidney suffered unhealthy levels of smoke. 2019 was the hottest and driest year ever recorded. The annual mean temperature was 1.50 C above the average 21.50 C for the years 1961 – 1990. Last year, the Australian average rainfall totaled 277.6 mm, which is way below the record low rainfall of 1902 – 314.5 mm. We will add to this that 2020 is expected to be even hotter and dryer. Why our Earth experiences Global Warming?
