Desert snow photography

The Sahara Desert is the largest desert in the world, which was formed about 2.5 million years ago and covers an area of about 9.32 million square kilometers. It can be said that the ecological environment of this big desert in North Africa is extremely bad, which is very unsuitable for the survival of living things. Weapons are in a state of high temperature all the year round, mainly including arid subtropical climate and arid tropical climate, which also shows that the climatic conditions in this area are long. According to public information, the average daily temperature in the Sahara desert is about 20℃, and the average temperature in winter is 13℃.

However, it can reach below 0 degrees in some areas at night, and it snows in the Sahara desert this time because of the great climate change. It snowed in Alai, the Sahara desert near Algeria. The lowest temperature in this area reaches 2 degrees below zero, so it is very cold. In the process of large-scale snowfall, it snowed not only in the Sahara desert, but also in the Tabuk area in the northwest of Saudi Arabia, so it happened in June+10 in 5438.

From the perspective of climate alone, the earth is really abnormal and more and more extreme, according to meteorologist Eric? Lester said that although there was snowfall near the Sahara desert in the past, it was very rare, and the snowfall in this desert was also unusual, mainly because the desert has undergone great changes under the influence of climate change. According to the monitoring data, the desert has obviously increased in the past hundred years, that is, the scope is getting bigger and bigger.

So the climate is changing the ecosystem model of the earth, and the earth may be really abnormal, just like it is being greatly updated. If the future climate continues, the snow in the Sahara desert may become the norm, and now the temperature of -2 degrees can appear, so there may be a colder climate in the future, so what is the current climate change? Start? . Many people are questioning whether the extreme climate change of the earth is related to the magnetic field, or is it one of the Little Ice Age and global warming? Cycle? In fact, judging from today's climate, is it global warming? Chain effect? So it belongs to the normal promotion under climate change.

In fact, these extreme snow, rain, strong storms, etc. , is not the most deadly to human beings. The biggest concern of mankind, that is, something that makes people a little uneasy, is actually in the polar regions. Although these two areas are sparsely populated, their influence is enormous. Carelessness may lead to the extinction of species on earth. Why do you say that? The first is climate-related. Global warming will accelerate the melting of polar permafrost, which will accelerate the melting of deep permafrost, and then the released methane will be strengthened.

So methane will strengthen the earth? Secondary greenhouse effect? This is the joint action of carbon dioxide and methane, the earth is warming faster, and there are also problems such as sea level rise. In addition, there is another problem, that is, the virus problem of frozen soil!
