The claims (e.g. here) that the Australian bush fires indicate a global warming “tipping point” has been passed and the earth is doomed are complete nonsense. There have been much larger fires in Australia in the past (e.g. here, here and here). Fires are a natural and necessary component in the life cycle of a forest.
“The current claim by many that human-caused climate change has made Australian bushfires worse is difficult to support, for a number of reasons. Bushfires (like wildfires elsewhere in the world) are a natural occurrence wherever there is strong seasonality in precipitation, with vegetation growing during the wet season and then becoming fuel for fire during the dry season.” click here
