Australia has not "always been a dry continent" rb. Just like New Zealand has it's rainforests, Aus was covered from the far north to Tasmania in forest before the first arrivals. Remnants of these forests still exist in all states of Australia today, once they were all one.![]()
Australia has always been a dry continent where fire has played an important ecological role. But as our contributing writer Fred Pearce reports this week at Yale Environment 360, the latest massive conflagrations there are evidence that a hotter climate has thrust Australia into a new normal where fires will continue to burn on an unprecedented scale. The country is among the most exposed to the gathering pace of global warming. Last year, Australia experienced its highest recorded temperatures, 2 degrees Celsius above the early 20th century average — twice the global increase. And as Pearce writes, higher temperatures are ensuring that vegetation dries out faster and further in droughts, exacerbating extreme fire risk. Read his analysis.
with that said
it may be MORE IMPORTANT than ever for us to help relocate animals/plant life,to another weather/climate compatible country for preservation purposes
the British did that successfully several hundreds of years ago,with plants,KEW GARDENS,and Animals
Also at e360, journalist Sonia Shah reports on how with thousands of species on the move as the climate changes, a growing number of scientists are saying the dichotomy between native and alien species has become an outdated concept. Instead, they maintain, efforts must be made to help migrating species adapt to their new habitats. For decades, conservation biology has characterized the movement of species as potential invasions that could threaten local ecosystems, leading to policies aimed at strictly repelling newcomers. But scientists argue such strategies could actually threaten biodiversity as global temperatures rise. Climate-driven range shifts are “one of the only solutions for species to adapt to climate change,” says one ecologist. Read Shah’s article.

What changed the wilderness to what exists today was the introduction of fire by humans.
This is from the Creative Spirits fb page. If you read the yellow section on this page it will let you know the Australian Wilderness, forests... were changed by the introduction of fire farming. Aboriginal land management & care
The land was changed by human intervention. The climate here has been changed by human intervention over thousands of years. Europeans turned up and multiplied it........every, every study undertaken since early times says this, and the new technology each time as the years go by backs up the one before..
The problem is....because of the thousands of years of burning, we are left now with what we have. Highly flammable Eucalyptus has taken more of a hold. The larger problem is, because of the slow deforestation, accelerated deforestation of the last 300 years has made it worse.........![]()
It is impossible to land manage, or firestick farm ravines, gorges, and vast areas of bush in Australia....It never has been...fire has never ever ever been manageable in Australia. But because of the changes made to the landscape over thousands of years through human introduced fire.........it's only become worse. The above photo is just a snippet of what is out there.
We didn't understand the effects fire had on climate change thousands of years ago, nor 300 years ago, nor 100 years ago........how do you change thousands of years? Plant more trees...not Eucalyptus though.
The blue haze is caused by Eucalyptus oil in the atmosphere...highly flammable.
