Australian Wild Fires Explained
HTML-код
- Опубликовано: 18 янв 2020
- Bush fires have been a natural part of the Australian ecosystem for at least 400,000 years, but whenever human beings get involved we see a spike in the data record. The first was 38,000 years ago when we first arrived there, and the second was around 1788 when the Europeans landed. This year's fires have been particularly brutal, and scientists are pointing to a number of climate change driven events that all combined in 2019 to provide the perfect conditions for catastrophic consequences. This week we take a look at the dire warnings our scientists are giving us.

Really good. Thank you. Unlike other commentators, you begin by admitting you are not a climate scientist, but then go on to give a good summary of what scientists of various disciplines are saying. So much fake news on facebook and youtube! We need you!
I used to be a volunteer firefighter for 20 years in the CFA, Victoria, Australia. I left for a few reasons but one was the attitude of many members that think the climate emergency is a hoax. I get so much hate sent my way from a small amount. I used to think the climate emergency was a hoax but i got educated thanks to community radio.
To the best of my knowlege official police and fire agency statistics for NSW and Victoria attribute less than 1% of the area burnt in this season's fires to ignitions that are considered suspicious, most were started by lightning.
What many people fail to realise is the Australia's ability to fight fires has increased significantly over the last 40 years, much better equipment, communications, weather forecasting, satellite information and water bombing aircraft have only been used in the last 25 years. Despite all these improvements the fire fighters are struggling to control these new conditions. A good summary of some of the reasons this is so.
Dave, thanks for spending so much time researching and informing us. I appreciate it.
Sadly the next phase has already started to occur with massive fish kills in Australia as the ash and other pollutants are now being washed into rivers. These climatic conditions have the ability to make large regions of Australia uninhabitable. Even then if this occurs regularly, you only have to look at the air pollution in the cities to suggest they will be less habitable as well .
Ironically Canberra just had a hail storm with the size of golf balls right in the middle of our summer, look up some footage, 100's and probably 1000's of cars with windows smashed and bodies bashed to a pulp. So 45 degree days all around Australia and right smack in the middle of all of it a cold enough change to produce a chronic hail storm....All 'cool and normal'....
Being a wildland firefighter during the apocalypse ensures job security. I have a feeling western Canada will be the next Australia within the next few years
Thanks for the information with the usual high standard of presentation.
This episode really hit the mark. As an Aussie this all feels very close to home, but it's comforting to see not only our own national resilience and solidarity come to the fore, but equally the care and concern from overseas.
Thank you!
A very important factor has been left out of the mix.
Him and Potholer54 both releasing videos on the bushfires today.
I live in the hills just outside Melbourne, Australia. I have lived for the past 20 years on a 1.25 acre block of nearly rain forest. The block backs onto a creek which supports a typical local tree fern environment. I have observed, over the past decade, changes to my garden. Several tree ferns, that I know have been growing there for 40 years, have died over the last 10 years. Large patches of ground ferns have also died off. I can only conclude now that this is a result of lower rainfall. I am facing an increasing war each summer trying to keep my entertainment area fern garden alive. These plants are experiencing longer extended periods of dryness. The main driver of the fires in Australia is drought and "dryness". When we have desiccated forests, we only need hot strong winds to provide the complete set of conditions, one spark, and a catastrophic inferno. In 2009 on Feb 7, Black Saturday, we had those conditions. We had not received any rainfall for 2 months, since early December. When catastrophic weather conditions arrived on Feb 7, late that afternoon, fires that started were backed by howling NW winds and completely uncontrollable. 173 people were incinerated.
Really interesting. Things I hadn't heard before, and hadn't appreciated either.
I find RUclips programmes such as this one far more informative and interesting than what I see on terrestrial TV such BBC or ITV. These are privately funded by the general public.
NSW 2019 was nearly 2 degrees above average (modern times) so with the 1 degree above pre industrial so is right to say that put at us 3 degrees C above pre industrial temps for 2019?
Is anyone the slightest bit curious as to why the NSW mean temperature is averaged from such a limited data range (1961 - 1990). I am. can someone let me know?
Lets sum this up folks,🤔were fcuked.
Another outstanding presentation, as expected, and thanks!
