We have just experienced the hottest May Day holiday on record, the temperature has been soaring everywhere, and it may be rare to open the air conditioner just after May Day, but what is more difficult than our days is Russia, which is not only experiencing the stage of explosive growth of the new crown epidemic, with 10,581 new cases in a single day, and the total number of confirmed cases has reached 125817!
And what is even more worrying is that the Siberian fires began to burn at the end of April, and now the area of the fire has exceeded 20,000 square kilometers, daring to catch up with last year's Australian fires!

In fact, as early as early April, it was reported that the Chernobyl fire in Ukraine caused serious radiation exceeding the standard, and these radioactive materials settled in the woodland and enriched by plants, as the fire was released into the air, resulting in local radiation exceeding the standard by 16 times, fortunately, the radiation did not spread with the fire smoke and dust, after all, the settled radiation was still a minority, and then the Ukrainian Ministry of Internal Affairs said that the fire had been controlled.

How serious were the Siberian fires?
According to Russian Minister of Emergency Affairs Evgeny Tsinichev, the fires are raging in Krasnoyarsk in central Russia, and according to data from April 27, the area of the fires exceeded ten times that of last year, and in the trans-Baikal region, the forest fires covered an area equivalent to the Hawaiian island of Maui (1,886 square kilometers), according to Thomas Smith, a geographer at the London School of Economics, according to satellite map analysis, About 20,000 square kilometers of forests in russia's Siberian region are being destroyed by fire!

The largest of these fires has exceeded 4,000 square kilometers, twice the size of the entire London, and according to NASA reports, most of the fires began to be connected to large areas on April 23 with the help of sporadic fires in several areas, helped by strong winds. According to NASA, the areas with the worst fires are Kemerovo and Novosibirsk regions.

How is the fire caused?
According to Sergei Anoprienko, head of Rosleskhoz, the head of the Russian Federation's forestry agency, the Siberian fire was mainly caused by unusually hot weather and the disregard for home quarantine policies for Russian citizens during the epidemic.

At the end of April, the temperature in many parts of Russia has exceeded 30 ° C, and many Russians can no longer stay at home in this weather, so a large number of Young Russians intend to carry out "wild isolation", barbecue and picnic fires have increased significantly, and every spring and summer, local farmers often set fires to wild grasses, wind to help fires, these sporadic fires finally spread into pieces, began to rage on the Siberian plains.

Fires are every year, but not as famous as the fires of 2019 and 2020, the Australian fires burned at the end of last year to the beginning of this year, burned for half a year, overfired an area of more than 170,000 square kilometers, a billion animals were killed in the fire, direct economic losses exceeded 5 billion Australian dollars, and 400 million tons of carbon dioxide was discharged into the atmosphere, which is more than half of Australia's annual emissions!
Fast-spreading Australian fires
The Australian fire in the southern hemisphere has not been extinguished for three months, and the Siberian Forest, the largest forest in the northern hemisphere, is afraid of being destroyed, from April 13 to this year, within half a month, it has burned 20,000 square kilometers, which looks much stronger than Australia.
What causes frequent fires around the world?
Global warming may be the backslider, since the Industrial Revolution, the global average temperature has risen by 1.15 °C, which may seem like a trivial figure, but extreme climates have increased significantly, and from global statistics, fires everywhere are increasing significantly, such as from 1984 to 2015, climate change has doubled the number of fires in the western United States, and the number of fires in Alaska has also increased rapidly.
Of course, there is also the Amazon rainforest in South America, the lungs of the earth, where forest fires have become the norm every year, and since 2013, the number of fires recorded between January 1 and August 22 every year ranges from 35,000 to 70,000, of which the Amazon rainforest fire in August 2019 was particularly serious, according to the analysis of the Amazon conservation group MAAP, the area of fire is about 70,000 square kilometers.

<h1 class= "pgc-h-arrow-right" > changes in global ocean currents, which may permanently change the Earth's climate</h1>
According to a study published in Geophysical Research Letters on April 17, 2020 by a team of researchers at UCL, the world's oceans are undergoing the biggest changes since the last ice age, with ocean acidification, tropical coral reefs being rapidly destroyed, and species such as herring or mackerel moving toward the poles. First of all, it will lead to a redistribution of fishery resources, which may mean fishing disputes, but more serious ones may lead to wars, such as the cod war half a century ago, although there will be no major conflicts under the pressure of NATO, but who can guarantee that more intense conflicts will break out in the twenty-first century of food security?

According to the UCL research team, the North Atlantic warm current is reaching a more northern north than in the past, and more warm seawater has reached the Arctic from the Atlantic Ocean, which will lead to a more serious consequence, which is another test of the Arctic since global warming, not only in terms of temperature, the Arctic is also getting warmer, and the Arctic ocean is also warming, all-round attempts to erase the Arctic from the earth!
The authors don't give why this happened, but they have found that global warming is a contributing factor to this serious consequence, and it is possible that the oceans are more sensitive to global warming than atmospheric circulation, so what will happen in the future? With global warming, such natural disasters are likely to increase!
If humans don't want to change, they have to adapt!
