Australia's climate is warming.
According to Bastian van Didenhofen, a scientific researcher at NASA, under the influence of wildfires, the clouds turn into cumulonimbus clouds, which can produce thunderstorms and heavy rain。The warming of Australian land has caused the air to rise and condense into clouds, and from the satellite**, the domes of these storms are very smooth, probably because there is not much wind shear. When the top reaches its highest point near the top of the troposphere, the top will spread around, thus causing this climate change.
In any case, the weather in Australia is a very complex and changeable pattern, and globally, tropical storm Claudia near Australia also affected them, forming thunderstorms along the coast. As a result, Australia gathers a wide variety of weather, so many friends in Australia pay attention. According to available data, wildfires in Australia have reached new heights.
According to the European Space Agency (ESA), about 10 million hectares of land have been burned and nearly 1 billion animals have been burned to death. However, this is a rough figure and does not rule out that it is still burning. The region will increase this intensity, so this is really bad news for Australia in 2020.
Of course, this is even bad news for our planet, because the impact not only affects them, but also indirectly affects the world. Mainly because the range of smog produced is too large, and therefore the climate change caused is much more severe. Above we have also briefly explained that the smoke has been determined to revolve around the earth, and it is conceivable what the climate in the area with smoke will be like.
As a result, wildfires have a wider range of impacts. After reading about Australia, let's take a look at the overall climate that is likely to happen in 2020. According to the World Meteorological Organization, in 2020 and beyond, as the temperature rises, we will face more extreme climatic weather, which is a clear trend where we humans change the climate state.
According to scientific statistics, the average global temperature has risen by about one degree Celsius since the industrial era, and the heat content of the ocean has reached record levels. It is also at a new level in terms of greenhouse gas emissions in 2019. Judging by current CO2 emission levels alone, our temperature will rise by 3-5 degrees Celsius by the end of the century.
Obviously, it is likely to exceed this temperature, as human emissions of greenhouse gases are still increasing.

It is not surprising that the fires lasted for more than four months and that there was too much carbon dioxide, which caused the climate to warm up, and then it turned into heavy rainfall.

Because of the savannah climate in northern Australia: the equatorial low pressure zone moves south in summer, low pressure appears on the Australian continent, and the northeast trade winds in the northern hemisphere deflect into the northwest monsoon across the equator, which comes from the low-latitude ocean, forming abundant precipitation, and enters the rainy season in winter: the subtropical high moves northward, and the Australian continent is controlled by the subtropical high, and the north is controlled by the southeast trade wind belt, and the southeast trade winds come from the interior, with less precipitation, and enter the dry season.
Due to Australia's recent persistent hot and dry weather, the bushfires continue unabated.

2020 is a year that makes many people want to "restart". Throughout the month of January, the most we heard was some unpleasant news. The first of these is probably a bushfire in Australia.
Bushfires in Australia have been burning since July last year. As we have already mentioned, bushfires are a regular occurrence in Australia, especially this year. The smoke-shrouded forests of Australia have touched the hearts of people all over the world, and have also brought many undesirable situations to Australia.
On February 12, the Australian bushfires, which had lasted for about half a year, finally ended. Statistics show that the fire lasted a full 210 days and burned 400 hectares of forest. In addition, 11.7 million hectares of land were burned, an area larger than Jiangsu Province and almost the size of seven Beijings.

It was extinguished on February 12.

Australia's wildfires have been raging for months, and by early January 2020, the wildfires had spread to more than 10 million hectares and killed 28 people. In New South Wales, Australia, 500 million animals, including 20,000 koalas, have been burned to the sea, and the total number of animals killed by the wildfires in Australia has exceeded 1 billion, and many species are on the verge of extinction.
Authorities deployed more than 500 firefighters to fight the fires in southern Australia, which had been raging for several days, forcing thousands of people to evacuate their homes. The Meteorological Department pointed out that the recent drop in temperature in the hill fire area has helped firefighting work. Australian authorities said that the wave of fires began on January 2 local time, due to the high temperature and strong winds, the fire is fierce, more than a dozen homes have been burned on the hills of Aredre, and more than 20 more may not be protected. >>>More

In order to better provide players with icon lighting services, since January 13, 2009, the "QQ Huaxia" icon lighting system will be fully upgraded, optimized and adjusted, and the chart lighting service will be faster and faster after the system upgrade. At the same time as this optimization and upgrade, we will also enable the new icon lighting rule, so during the system adjustment period from January 13th to January 21st, all users who have lit up the QQ Huaxia icon will be automatically extinguished from now on, and it cannot be lit during the adjustment period. After the system upgrade is completed, the icon will be lit up after the system is restored, and users who have the icon turned off during the period can automatically resume the icon after January 21.
