The worst drought in 1200 years is coming, 2021: How much will mankind suffer?

On May 11, 2021, watchers.news (Observer Network) reported that the US federal drought monitoring map shows that most of California's San Francisco Bay Area is in extreme drought, with a total area of ​​more than 37,000 square kilometers, and will suffer more than in the past. 130% of the average wildfire risk in 5 years, and just last year, California experienced the largest fire in history!

California is suffering its worst drought in more than a thousand years

ABC7 NEWS meteorologist Mike Nicco (Mike Nicco) said that the rare drought has covered the California area, and the extreme drought coverage of the entire California has increased from 53% to 75%, which means that three-quarters of the state is already in the state. On the brink of collapse, California is being hit by a drought rarely seen in history.

When I first saw this picture, the author was also a little confused. After reading the caption, I realized that this was a yacht marina. This is Granat Bay, California, USA. form this regular structure.

In the past few months, the western United States, which includes Nevada, Arizona, New Mexico and Utah, has experienced its worst drought since 2000. Every February is the traditional rainy season in the southwestern United States, and the water storage of lakes and vegetation will also be completed during this time period. However, in February this year, there are thousands of miles of land in the western United States, including Arizona, and many areas have not even rained. !

A paper in the journal "Nature" pointed out that 2000-2018 was the second worst drought record in the United States in 1200 years, and the mainstream American media, which are good at creating headlines, have called this year's drought in the western United States "the worst drought in 1200 years"!

Severity of drought in western U.S.

Of course, the history of the United States is only more than 300 years old. Where did the data from 1200 years (thirteenth century) come from? However, scientists can always find those rare dry years from tree rings that have lived for hundreds of years. It is clear that this year's drought in the western United States is really not ordinary.

Many parts of the world are suffering from historically rare drought

Not only the United States, a report on May 11 pointed out that Mexico has also encountered a rare drought. By the end of April 2021, about 85% of Mexico's regions have experienced severe drought, and many lakes are facing drought or even drought. This includes Lake Cuitzeo, the second largest freshwater lake in Mexico.

Lake Triz is an inner-flow lake in the state of Michoacán in central Mexico, with an area of ​​300 to 400 square kilometers. At this time last year, Lake Triz was a lake with rippling blue waves and sailing boats, but in April this year, it was Only the silt remains, and the moisture in the silt is also being evaporated!

A drought in the western United States and a scramble in Mexico are not covered by the rest of the globe, with southern Madagascar also suffering its worst drought in 40 years.

In the previous three months, southern Madagascar had received less than 50 percent of the normal rainfall. In addition, up to 60% of the harvest is expected to be lost in the coming months. According to the Welthungerhilfe (WHH) report, as of May 12, severe famine has been experienced in dry areas, more than 70,000 children are severely malnourished, and 1 million people are facing starvation. WHH has called for emergency assistance.

When it comes to drought, there is no way to forget Taiwan Province of my country. As of May 2021, most of the reservoirs in Taiwan Province have dropped to critical levels, and some storage capacity has dropped to 10%. This is the worst drought in the province in 56 years. .

Compared with 2015, which was the worst in recent years, the situation this year is much more severe. In the most drought-affected areas, the supply of tap water has been severely restricted. In some areas, tap water has been cut off for two days, including Taichung City, which has a population of 2.8 million. , Miaoli and Changhua counties are also threatened by severe drought.

Drought in Taiwan Province of my country

According to meteorological experts, the drought in Taiwan Province will continue until late May, and the relief of the drought will require replenishment of water in five typhoon seasons. If the typhoon season is delayed again this year, the people of Taiwan Province are estimated to be crazy!

What's going on with the drought in 2021, is the end of the world really coming?

I remember that some people left a message on social media saying that compared with 2021, 2020 is only pediatrics. Although many netizens refuted this statement, in fact, from last year to this year, the situation is indeed much more serious!

When everyone thought that the new crown epidemic was about to turn a page, the real king of India suddenly appeared, and from the beginning, 300,000 to 400,000 people were diagnosed every day, and it has been going on for almost a month, and it has not weakened. signs! Are you afraid of this scale? And Indian-born virus experts say without hesitation that the total number of infections in India may exceed 300 million to 500 million!

When you think that after so many people in India are infected, they will definitely form a general immunity. This virus has mutated. Unlike last year’s strain, which mainly killed the elderly, the infection rate and the fatality rate of young people have risen sharply. To destroy India? Of course it's not that exaggerated, but there is such a nuclear bomb-level epidemic power in the world, who can take it easy?

Far too far, the biggest threat in 2020 is not only the new crown epidemic, but also the La Niña phenomenon under global warming! Since the winter of 2020 entered La Niña, the world has been shrouded in the shadow of La Niña, a phenomenon that is the opposite of El Niño, known as the "Eastern Pacific Cooling Phase"

The atmospheric circulation over the Pacific Ocean is called the Walker Circulation. When the Walker Circulation becomes weak, the sea water cannot blow to the west, and the sea water in the eastern Pacific Ocean warms, which is El Niño phenomenon; but when the Walker Circulation becomes extremely strong, La Niña occurs. Generally, the La Niña phenomenon will follow the El Niño phenomenon. In the second year of the El Niño phenomenon, the La Niña phenomenon generally occurs, and sometimes the La Niña phenomenon even lasts for two or three years.

As early as the end of 2020, meteorologists predicted that the continuation of the La Niña phenomenon in 2021 will cause severe drought in the southwestern United States and Mexico, because strong westerly winds will carry all the water vapor in the western America, while Australia and Indonesia and Southeast Asia will increase rainfall, but Taiwan Province and Madagascar are somewhat unexpected.

Predictions from NOAA's Climate Prediction Center suggest conditions won't get better in the western U.S. anytime soon. Hot, dry weather expected to continue into late October

This La Niña phenomenon is somewhat different from the past phenomenon. Under the conditions of global warming, the La Niña phenomenon is weakening. Meteorologists have not been able to determine whether the drought in Madagascar and Taiwan Province this year is related to the weakening of the La Niña phenomenon, but there is no doubt that, The catastrophic climate of 2021 will still refresh your views.

Meteorologists say that although La Niña looms over 2021, this summer will still be the hottest year, the real high temperature season has not yet come, and the average temperature in May this year is also somewhat unexpected, perhaps this is for this year's Warm up for the hot season!

Fires in California are bound to happen on a massive scale because dry thunderstorms can occur over time even if there is no artificial fire, which is the arsonist of California's annual fires, and this year's dry season starts earlier, so California fires are already scheduled.

After the hot summer, the typhoon season is coming again. Behind the rise in global temperature, the duration of the typhoon has increased significantly, because a large amount of water vapor has filled the typhoon with more energy, making the weakening ratio of the typhoon after landing from the past 75%. % dropped to 50%, which gives the typhoon more energy to do more damage!

This is not good news, but the consequences of global warming have already been created, and future typhoons will only be more violent!
