Camels walk in the snow of the Sahara Desert. Why does it snow in the Sahara Desert?

The Sahara Desert is the largest desert in the world. It was formed about 2.5 million years ago and covers an area of ​​about 9.32 million square kilometers. This large desert in northern Africa can be said to have an extremely harsh ecological environment and is very unsuitable for living things. For survival, weapons are kept at high temperatures all year round, mainly including arid subtropical climate and arid tropical climate, which also shows that the climate conditions in this area are long-lasting. According to public data, the annual average daily temperature in the Sahara Desert has an annual range of about 20°C, and the average winter temperature is 13°C.

However, some areas can also reach below 0 degrees at night, and this time it snowed in the Sahara Desert. It was also due to the dramatic changes in climate that snow fell in the Sahara Desert area near Algeria. , the lowest temperature in the area reached -2 ​​degrees, so it was extremely cold. During the large-scale snowfall, in addition to snowfall in the Sahara Desert, snowfall also occurred in the Tabuk region in northwest Saudi Arabia. Weather, so such a climate phenomenon in January is indeed a dramatic temperature change in the Sahara Desert.

If you look at it from a climate perspective alone, the earth is really abnormal, and it is becoming more and more extreme. According to meteorologist Eric Lester, although the Sahara Desert There have been snowfalls in nearby areas before, but they were very rare. The snowfall in the desert this time is also extraordinary. It is mainly due to the influence of climate change. The great changes in the desert are also changing. According to monitoring data It shows that deserts have grown significantly over the past century, meaning they are getting larger and larger.

So the climate is changing the ecosystem model of the earth. The earth may really be abnormal and is undergoing a major renewal. If the climate continues in the future, snow in the Sahara Desert may become the norm. Now it can If a temperature of -2 degrees occurs, a colder climate may occur in the future, so today's climate change may be the "beginning". Many people are questioning a question, that is, whether the earth's extreme climate changes are related to the magnetic field, or whether it is a "cyclical cycle" of the earth's Little Ice Age and global warming. In fact, judging from today's climate conditions, it is the global The "cascading effect" of warming is therefore a normal progression under climate change.

In fact, these extreme snows, rains, strong storms, etc., are not the most fatal impact on human beings. The biggest worry of human beings is the thing that makes human beings a little uneasy? In fact, Or in the Arctic and Antarctic regions. Although these two regions are sparsely populated, the impact is very huge. If you are not careful, you may cause the disappearance of species on the earth. Why do you say this? First, let’s talk about climate. The warming of the earth will accelerate the melting of permafrost in the Arctic and Antarctic regions. This will accelerate the melting of deep-seated frozen soil, and the methane released will be even stronger.

In this way, methane will enhance the earth's "secondary greenhouse effect". This is the simultaneous effect of carbon dioxide + methane. The earth will heat up faster, and correspondingly there will be problems such as sea level rise. In addition, In addition, there is another problem, and that is the problem of viruses in permafrost!
