Djokovics concern is entirely reasonable. At this time, Australia, after more than four months of wildfires, has reached an appalling level of air quality. In mid December 2019, NASA analysis shows that since August 1, forest fires in New South Wales and Queensland have emitted 250 million tons of carbon dioxide. As of January 2, 2020, NASA An estimated 306 million tons of carbon dioxide have been released. By contrast, Australias total carbon emissions in 2018 are equivalent to 535 million tons of carbon dioxide. Melbournes air quality index once exploded to 278, which is a very unhealthy level. For comparison, Shijiazhuang, a city with poor air quality in China, has an air index of 160-180 when it is in haze weather. Sydney, another big city in Australia, is lucky. Because it is at the seaside, the air quality is still very good.
A lot of Australian athletes are praying for their motherland at this time. NBA spurs player mills made 6-10-3 shots in the game of beating bucks, but after the game, he was not concerned about beating the first team in the league, but said: I am willing to change my 3-point into rain at any time to put out the fire in Australia. Previously, he tweeted several times, calling for attention to the serious fire in his hometown.
1u3001 How serious is the cause of the fire
Australia is located in the southern hemisphere, with a land area of 7.68 million square kilometers. The country can be divided into three regions: the eastern mountainous region, the central plain and the western plateau. The central part is a vast desert, dry and rainless, while the eastern part of the great watershed has abundant rainfall. The population density of Australia is low (3 people / km2), and the population is mainly concentrated in the East and southeast coast.
One of the characteristics of Australia is that there are few people, large land and fast spread. Long before human landing in this continent, the mountain fire has been burning for thousands of years. In hot and dry season, there will be frequent field fires in Australia, which will destroy a large area of land every year, and cause property loss and casualties.
Specific Australian native flora relies on bushfires, which often occur alternately and become an important part of Australian ecology. For some Eucalyptus and patchwork trees, fires can crack plant seeds, allowing them to take root and sprout. The fire also promotes new vegetation, and some other species can recover quickly from the damage caused by the fire.
It can be said that Australians have been used to forest fires for a long time. Since 1851, more than 800 people have been killed by forest fires in Australia. As for the causes of previous fires, they may be caused by natural causes, lightning, extreme weather and dry vegetation. In terms of man-made reasons, in 2009, man-made arson also caused serious forest fires in Australia.
As for the direct cause of the fire, it is the continuous drought and strong wind. In the drought before the fire, the impact of reduced rainfall intensified the record monthly average temperature, which lasted for 36 months until October 2019. The combination of high temperatures and droughts has resulted in a severe low fuel moisture content, and Gavin Freeman, a response controller at the Victorian fire department, points out that the potential dryness of the forest has resulted in a very high fire risk. The average temperature in Australia this year is 42 degrees Celsius, the highest ever.
In July 2019, David Jones, a climatologist at the Australian Bureau of meteorology, told the Bureaus workshop on climate: our records can only be traced back to 120 years ago, but in terms of rainfall records, the current rainfall in this period is the most serious record in 120 years. According to paleoclimate data (analysis of historical weather trends), the closest is a high temperature period from 2 to 3 million years ago. Although Australia has experienced great rainfall changes and hot summer for thousands of years, the annual average temperature in Australia has increased by nearly 1 u2103 since 1900. Since 1990, the average rainfall in the southeast of Australia has declined. The most serious drought in the country occurred in the 21st century.
On the one hand, in the days of the fire, ffdi of MacArthur forest index in Australia has reached a historical peak. There are ten strong winds (60 miles per hour) in the place where the fire happened. The fire is so strong that it burns uncontrollably.
Climate and fire experts agree that climate change is an important factor in increasing the frequency and intensity of fires in southeastern Australia. Everyone underestimated the role of climate change in triggering fires.
The fire has been burning for nearly four months. Up to now, 84000 square kilometers of land in Australia have been burned, and more than 1400 kilometers of coastline are burning, which is equivalent to burning all the way from northeast to Shanghai. More than 2500 buildings have been destroyed, 25 people have died, and 500 million animals have been buried in the crematorium. The fire also surpassed the California fire in 2018 and the Amazon fire in 2019, making it the second largest fire in human fire history.
2u3001 Why did the fire last so long? The Australian government has a lot of responsibility
The chief executive officer of the Australian Council of small business organizations said that the Australian federal government stopped the preparations for forest fires because some people in the government firmly believe that there is no such thing as climate change, or that human beings have no impact on climate change, and they firmly believe that no extra work or extra efforts should be made because they do not believe in climate change.
Australian Prime Minister Scott Morrison has proved the accusations made by the people. He said in a talk that Australia has played its own role in the process of coping with international climate change.
At a briefing with fire officials, Morrison said he knew Australians were worried about the fire, but insisted that Australias emergency response was the best in the world.. Lets see how he does his best.
Listen to this word. If necessary, look at this data. There are 100 fire spots, 1300 firefighters in total? Can this work?
On December 22, 2019, the fire has been burning for three months. Why did Morrison go? He went to Hawaii for a holiday. David Elliott, Secretary of state for emergency affairs of New South Wales, also went to Europe for a holiday at this time, and the premier of Queensland, paraszuk, went on a cruise.
Morrison was caught trying to shake hands with two residents of the town of cobargo, who refused to shake hands with him, while visiting the fire affected town of New South Wales. Morrison took their hands and shook them in spite of their refusal. In an interview with Andrew Constance, a member of the New South Wales Freedom Party, Constance described the incident, saying local people may have given him the welcome he deserves.. Morrison didnt seem to care about the criticism, but later said, people are angry. If people want to point the finger at me, its their business.
We all know that fire fighting, human and material resources are very important. Even if there are fewer Australians, the fire fighting budget is still cut every year. Australia only has 15 million Australian dollars of national air fire fighting funds a year. In order to save costs, it is generally not until the local summer in December that it will send out airplanes to put out the fire. This fire did not happen well until December, when Australia sent out the national defense forces to help put out the fire On December 24, 19, the Morrison government announced that volunteer firefighters in the federal public service would receive at least 20 working days of paid leave. On December 29, the government announced that volunteer firefighters recruited for more than 10 days will be able to get financial compensation.
When the fire was out of control, Morrison still had to rely on volunteer firefighters to help put out the fire, to give some compensation, the shortage of manpower, it was really disappointing.
At present, the fire in Australia has reached a very difficult point to control. New Zealand, Canada, the United States, Malaysia and other countries have sent professional Chinook helicopters, armed forces and professional firefighters to international assistance to help Australia fight this serious fire together. As we are thousands of miles away, we can only pray silently that the fire will be smaller for the disaster brought by nature.
