That ecosystems like rainforests, that rarely burn in nature, are now burning is a clear "warning light" that fire behaviour has changed. Australia's deadly bushfires sparked in September 2019 and have been blazing ever since. There are general causes, such as the distribution of pyrophilic plants linked to the fires of Aborigines over many years, the seasonally dry, desert climate over the center of the continent, and the recent efforts at protection of natural reserves near populated areas that has resulted in the accumulation of flammable vegetation. But the root cause is lack of trees. Similarly, increased humidity decreases the chances that a bushfire will start. Bushfires in Australia will cause more and more harm as greater numbers of people choose to live in the path of disaster, experts say. It’s important to note that while all of these factors play a part in the ignition and spread of fires, they are aided by the rise of climate change, which has led to the drier, hotter conditions where bushfires thrive. Australia has been in the grip of a deadly bushfire season since September 2019.

One of the biggest changes to occur since 1788 is our widespread settlement across flammable landscapes. Rain is created by moisture in the grown/bodies of water, warmed by the sun and being evaporated. It's a simple question with an incredibly complex answer that involves fuel management, firefighting techniques, landscape planning, building design and environmental history. Nonetheless, Indigenous people continue to make a critical contribution to fire management across Australia and have a lot more to offer to help shape sustainable solutions. In particular, Geoscience Australia: In particular, Geoscience Australia: delivers the Digital Earth Australia Hotspots website that provides national situational awareness for active bushfires and a historical archive on bushfire hotspots TO SAY SO DEMONSTRATES A VERY POOR, EVEN INEXCISTENT UNDERSTANDING OF HOW RAIN COMES TO BE. Despite repeated warnings, we keep building houses in places that will burn, putting increasing numbers of people at risk. Through careful research, fire scientists have learnt how to design buildings and their grounds to substantially reduce fire risks. Unfortunately, in our quest to understand 'why', many people have been quick to throw accusations. These same billiaonairs should pay for every house, and every animal lost. By subscribing you agree to our Terms of Use and No trees = no rain. The majority of bushfires in Australia were started either accidentally or deliberately by humans as of November 2019, at a 35 percent and 13 percent share of total bushfire ignitions respectively. Bushfire hazard results from the complex interaction of highly dis-parate anthropogenic and natural factors. In mid-January 2020, a wave of heavy rain finally brought relief in some areas hit by bushfires … The fires created unprecedented damage, destroying more than 14 million acres of land and killing more than 20 people and an estimated 1 billion animals. Australia’s temperatures have risen faster and higher than anywhere else in the world. (CNN) The Australia wildfires are a countrywide catastrophe, mainly caused by drought and extreme heat, but dozens of people are directly to blame for some of the problem, officials say. An absolutely astonishing set of bushfires is burning around Australia currently, producing surreal images like those of evacuees fleeing to beaches—or boats—for safety. Funny you said because, no trees = no fire too. Bushfires have killed approximately 800 people in Australia since 1851, and billions of animals. In a drought, that is extremely little and thus why we have the present bushfire crisis. Climate change is making a bad situation worse. Available fuel: This is the volume of bark, leaf litter and other natural dry material that is consumed by the fire as fuel. It is crucial to study the Australian bushfire to determine what exactly happened in the region. The moisture of the fuel is another critical factor. If they did that, our bushland in all those places where is so thick that firefighters can’t access the original fires to extinguish them before they take hold and become infernos wouldn’t have such an explosive and dire fire ability. The first major bushfires began even before the official arrival of spring in June and then new out-of-control fires sprung up at the beginning of Sept. 2019. Trees don’t produce rain or water.

Natural causes are to blame … Bushfires are burning and many Australians are suffering directly. The message: the cause is arson, not climate change. There is good reason to understand our current situation as an intellectual transition from the stage of "what climate models tell us about the possible effects of climate change on bushfires", to "observing and experiencing extreme, unusual, and ecologically and economically damaging bushfires driven by anomalous climate conditions". However, the 2019-2020 season proved to be unprecedented in many ways. Concerningly, we are experiencing increasingly unprecedented extreme fire weather conditions associated with prolonged drought, desiccating high temperatures and strong winds. The bushfires are often started by natural causes such as lightning strikes, however humans are also sometimes to blame. The deterioration of fire weather patterns, apparent around the globe, closely matches the prediction of climate change analysts. And we need to accept this is a long-range program, not a quick fix. Here is the recent article from BoM that shows it and THEY KNOW AS IT IS THEIR JOB TO KEEP THOSE RECORDS: https://www.9news.com.au/national/100-years-of-temperatures-bushfires-normal–bom/6fade093-124e-4c08-b8e4-91c36c416e17.

In the first week of 2020, hashtag #ArsonEmergency became the focal point of a new online narrative surrounding the bushfire crisis. Add that to the fact that Eucalyptuses and Malelaucas (our most common native trees) are very volatile as they are rich in flammable oils and that higher regions and many commercial plantations are rich in pines, also a very volatile species, and you have a recipe for disaster. So, with unprecedented extreme fire weather conditions upon us, what can we do to safeguard ourselves against a more flammable future? if (typeof siteads.queue !== 'undefined') { Deforestation all around the world is criminal, to say the least, but trees ARE NOT responsible for the creation/production of rain.

Bushfires in Australia will cause more and more harm as greater numbers of people choose to live in the path of disaster, experts say. More commonly, fires are ignited by legal or illegal burn off that may run wild, lightning storms and electrical faults – with lightning accounting for “about half of all ignitions in Australia.” Many others are started accidentally by human fault, such as via campfire embers. The warning was based on the Northern Australia bushfire seasonal outlook noting exceptional dry conditions and a lack of soil moisture, combined with early fires in central Queensland. Understanding this, and how they’re spread, is essential to identifying the key causes behind Australia’s current crisis. No tree will “create” water out of nowhere.

The people of Australia had always adopted bushfires as a tool to clear land for agriculture. At least 24 people have died, many are missing, and roughly 4.9 million hectares and one thousand homes have been destroyed in New South Wales, one of the hardest-hit states. They are, however, a very intrinsic and extremely important cog in the engine of keeping the planet (and all us, plants and animals) healthy and balanced.
