What is the impact of the fires in Australia on the global ecosystem?

The reason why Australian forests catch fire is mainly a normal natural ecological phenomenon. Therefore, it does not have any so-called impact on the global ecological environment.

The fire was undoubtedly devastating, depriving all kinds of animals and plants in nature from their homes, and also bringing problems of air pollution and environmental management to the people of Australia as a whole.

The Australian fires have caused the glaciers in Antarctica to melt at a seemingly faster rate, with irreversible effects on the entire continent's biological system, which will take at least decades or even centuries to recover.

The fires in Australia will kill many animals, trees and other plants. Then some animals will have no place to live, so they will also come to take away the place of humans, which will make the global warming worse.

The fire in Australia has an impact on the global ecological environment, and the burned area has reached nearly 60 million hectares, which seriously threatens the survival of local people, and the ecological environment is undoubtedly greatly damaged, which will make global warming serious.

If the fires in Australia continue, what will be the impact on the planet's environment?

Central Australia is controlled by the subtropical high pressure zone all year round, and the desert is formed by little rainfall, and because of the influence of the subtropical high pressure, the forests in the south are often affected by the dry, hot prevailing winds blowing from the north, causing forest fires.

Forest fires not only destroy surface vegetation and reduce biodiversity, but also pollute the air.

What is the reason for the continuous burning of the fires in Australia?

The fires in Australia have been burning for more than four months, killing at least 27 people and killing 500 million animals. Why can't a forest fire be extinguished in a huge Australia? First, Australia's first response was wrong, and even Prime Minister Morrison went abroad for a vacation at a critical juncture; Second, Australia's climate is abnormal, with the highest temperature even reaching 49 degrees in December 2019; Third, the root cause is that Australia** has pursued a very wrong energy policy and has not paid enough attention to climate issues.

1.Australia** made a mistake in its response. Many Australian news** reported that the country's Prime Minister Morrison wanted to shake hands with firefighters and people when he went to the disaster area.

As a result, Morrison was rejected. Why? Australians hate Morrison's hypocrisy and are dissatisfied with Morrison's policy of hard fire.

As Australia's prime minister, Morrison could only scratch his head in embarrassment. So, why do Australians treat Morrison like this?

It turned out that Morrison's failure to respond was one of the main reasons why the fire was not contained in the first place. As early as September 2019, Australia's climate department stressed to Morrison that the number of bushfires at the end of 2019 and the beginning of 2020 would be higher than in previous years. As a result, Morrison was very unimpressed and even cut the budget of the fire department.

Most interestingly, in December 2019, Australia's bushfires were already very serious. However, Morrison, as Prime Minister of Australia, went on vacation to Hawaii!

Australian Prime Minister Scott Morrison.

2.Australia's climate is unusual. In fact, much of Australia's more than 7.6 million square kilometres of territory has a tropical climate.

At the end of each year, bushfires or bushfires break out in Australia. However, this year, Australia's climate has been unusually hot, with very little precipitation. In December 2019, Australia's highest climate reached 49 degrees.

In addition, the El Niño-like phenomenon "dipole" in the Indian Ocean is also one of the real culprits behind the Australian wildfires. The 2019 "dipole" reached its highest peak since 1870 and also contributed to the fires in Australia this year!

3.Australia's wrong energy policy and climate policy.

Australia is a "country sitting on a minecart", and iron ore and export are its pillar industries. In the face of surging public opinion, Morrison even said that he and climate experts had "over-analyzed" the objective reality that climate change would lead to aggravated fires. Morrison's remarks certainly drew sharp criticism, with Australia** criticizing that "in the face of an unprecedented crisis, his response is not to defend the country, but to defend the fossil fuel industry." ”

Reasons, and information.

Satisfied with the answer. zhanghaitao816lv13

Australia's arid climate and oil-rich eucalyptus forests mean that bushfires are one of the country's inevitable sights. There have also been several major bushfires recorded in Australia's history, such as Ash Wednesday in 1983 that killed 75 people, and Black Friday in 1939 that killed 71 people.

However, Victoria's bushfires are the deadliest in the country's history, and experts believe the problem is linked to climate change.

Morgan, director of the Australian Centre for Cooperative Research on Forest Fire, said: "Climate change, dry weather, has changed the nature of forest fires, the size of the fires and the ...... of time they burnThis weekend's wildfires highlighted the importance of scientific research to advance our understanding of the various impacts of wildfires. ”

Australian poet McKeller described Australia as "arid land and flooded plains", while Adams, a bushfire expert at the University of Sydney, said there was evidence that Australia's climate was becoming increasingly volatile.

Australia has a large area of forest cover, and there are a number of fires every summer.

The Melbourne fire, according to **, is first due to the severity of the fire. Victoria has been under control of heat for the past week, with a high temperature of 43 degrees Celsius lasting for a week, a record since 1908. By the time bushfires began raging on February 7, temperatures in Melbourne, the state's capital, had risen to 46.4 degrees Celsius.

Prolonged heat and drought have made the wildfires more likely to spread, while winds of up to 115 kilometers per hour and some incidents of arson have accelerated the spread of the fires, engulfing many people in flames before they have time to flee their homes. Victorian Premier Brumby said the fire was as terrible as a war. Because the fire was so intense, there was little firefighters could do about it.

So far, a total of 180 people are suspected of arson, both adults and minors, of which 24 are suspected of intentionally setting fires in the DAO forest, 53 are suspected of failing to comply with the fire ban, and 47 are suspected of discarding lit cigarettes or matches on the ground. In addition, a fire near Parramatta in Sydney's West End is under investigation and has been allegedly accused of intentional arson. The cause of the fire is difficult to pinpoint.

The wildfire is known since 2009"Black Saturday"One of the worst fires in Australia since the fire, which killed 173 people. In 1974, 100 million hectares of land in central Australia were destroyed by wildfires.

One of the main drivers of fire intensity, fire spread rate, and fire area is temperature. Last spring, Australia's fire-prone climate hit an all-time high, according to a report by the Bureau of Meteorology (BOM). Warmer temperatures and less rainfall during the cooler season.

Unusually hot weather accelerated the fires. Meanwhile, according to the Victorian Department of Emergency Situations, dry lightning was responsible for the multi-disaster caused in the East Gippsland region of Victoria in December.

In Australia, wildfires are induced by hot, dry conditions in the summer, and are not a new DAO

Fresh things. However, this time it was the hottest on record.

The combination of persistent drought and strong winds caused catastrophic fires.

So far, according to official Australian statistics, more than 6.3 million hectares have been affected.

The fires in Australia are equivalent to burning half of Jiangsu, 3 Beijing, and 2 Belgium, 7 times more than last year's Amazon rainforest fires that shocked the world (900,000 hectares burned), and 60 times more than last year's California fires (which burned 10,000 hectares)!

The Australian fires were one of the worst fires in human history, burning for four months and killing 500 million animals. Brother Lightning today analyzes the main causes of the fires in Australia.

I wonder what the sloths do when the fire comes? Are they still lazy and slow?

Arson, cigarette butts, etc., have already arrested a lot of people.

It was reported that the fire was caused by a lightning strike.

They're the opposite of the season in our country, we're in winter, they're in the summer, the air is dry, and a big thunderbolt hits a dry branch, and that's it, it's really miserable, and today's news report is that hundreds of millions of animals have been burned to death.

The fire in Australia is relatively serious, because the fire has been burning for several months, so not only Australia, but also the global climate and environment have a certain impact. Because this large-scale combustion caused the amount of carbon dioxide in the atmosphere to rise a lot, and it was also accompanied by sulfur dioxide.

and other toxic gases. However, the biggest impact of the disaster is on Australia's local ecology.

As a result of the burning, large areas of vegetation and trees were burned to death, and countless animals were also killed in the fire. Therefore, there will also be some damage to the species diversity of local flora and fauna. The disaster left many animals homeless, and some were at risk of extinction.

And once the food chain.

If it is broken, many animals will become extinct. And it is definitely not an overnight thing to recover, so this fire is a headache for the whole world.

However, the most leisurely is actually Australia**, which has been engaged in the development until now, and Australia** has been slow to carry out firefighting operations. That's why the fire will continue to burn, and even some isolation strips can organize this fire that shouldn't have happened. Therefore, the slackness of the local ** is also one of the reasons for the spread of the disaster.

Although it is said that Australia has fires all year round, and every time it is waiting for it to be extinguished naturally. But it's not like the fire lasts for months and they are still waiting, so no reason is an excuse for their dereliction of duty.

Now that the fires in Australia are well known, they have gone to extinguish the fires, and there are so many firefighters from other countries who have helped in the past to effectively continue the fires to continue to spread. However, although the fire has been extinguished by the rain, many firefighters have died in the fire. This is also one of the reasons why our hearts ache.

Let's hope that this kind of disaster will happen a little less.

These 210 days of fires will first cause serious damage to the atmosphere of our air, destroy the entire ecological environment, and have a great impact on the animals and plants in the large forest, causing an imbalance in the earth's ecological chain.

In response to this problem, my personal opinion is that the 210-day fires in Australia have brought serious smog to the world, and the long-term burning has exacerbated global warming, and the earth's ecological environment has become worse and worse, seriously affecting the survival of wild animals.

Fires for most of the year produce huge amounts of carbon dioxide, which are already emitted around the world, which will exacerbate climate warming and lead to sea level rise, and the global climate is prone to instability.

The Australian fires, at least hundreds of millions of animals died in the fires, the biodiversity was impacted, and the carbon dioxide and other gases produced by the fires also destroyed the ecology and accelerated global warming.

He has reduced the number of species in the world, after all, many creatures died in Australia during the 210-day fires.

The fires have exacerbated the global warming effect and exterminated many wild animals.
