Is it snowing in the Sahara desert? Will the rhythm of global warming stop?
Last year's Golden Week, although the sun shone brightly in many parts of the country, some places, such as the central region, suffered the "coldest Golden Week in history". During the Golden Week in some central regions, the temperature dropped directly to 0℃-5℃, which made many people drag down their down jackets from the bottom of the box and put them on during the Golden Week.
After entering 202 1, the temperature is abnormal. It is clear that when walking on the ice on March 9, the temperature in some areas has reached a dozen or twenty degrees, but then the temperature will plunge into an ice cave, which is simply a random switch all year round, making people really confused about what the weather is like now.
Not only in some parts of China, but also in other parts of the world. For example, the Sahara desert in northern Africa has ushered in snowfall? !
The thing is, the Sahara desert in northern Africa is located at the equator, which should have been the hottest place, but in June+10 this year, some Sahara desert areas in northwest Algeria were neither too hot nor too cold, but it snowed abnormally. Judging from the photos released so far, although the snowfall did not cover the entire Sahara desert, the overall snowfall was indeed not small. If it is not directly named the Sahara Desert, simply looking at the photos will really think that it is a snowy mountain, which shows that the snowfall is also very huge. It snows in the desert, and it cools down on a large scale! Is the world really getting warmer?
Generally speaking, in the cities near the Atlas Mountains in northern Algeria, the annual temperature of 1 month will basically remain around 14 degrees Celsius, even if it is low. But just this month, the temperature in this area dropped directly to -3℃, which triggered a large-scale snowfall and directly turned the yellow desert into a "white desert".
In fact, this is not the first snow in the Sahara desert. Far away, 1979, 20 16 years, it snowed in the last two years. Four years ago, the snowfall directly reached the thickness of one meter, and the snowfall was really amazing.
So many netizens have noticed that since 20 16, the snowfall frequency in the Sahara desert is increasing, and everyone is saying that the climate is getting warmer. Why did it snow in the desert this year, and the temperature dropped widely? Combined with the extreme abnormal weather in the world last year, can it be said that the world is not warming but getting cold?
In fact, this view is really not groundless speculation by netizens. As early as 20 15, the Daily Mail published an article saying that some scientists found that the sun may enter a minimum period in 2030, which means that the earth will encounter the Little Ice Age, and 2020 will be the beginning of the Little Ice Age. So is this really the case? Is the earth really getting colder instead of warmer?
In fact, extreme weather in some areas simply cannot represent the climate and ecology of the whole earth. According to rigorous scientific data, global warming caused by greenhouse effect caused by human activities is still the general trend of the whole earth.
According to the climate data monitored by weather stations around the world, in the past 2020, although the global local temperature plummeted due to La Niñ a phenomenon, the temperature of the whole earth did not decrease, but gradually increased. Compared with the 1990s, the global land and ocean temperatures rose by 1.6 degrees Celsius on average.
This can be seen from Wang Xiangjun's glacier exploration. In the short video shot by Wang Xiangjun, we can clearly see that glaciers are melting rapidly, thus forming many blue holes in glaciers. Many glaciers continue to melt in the season when they should freeze. This is a phenomenon brought about by global warming.
The north and south poles are most affected by global warming, especially in the Arctic, where there is no continent and we can only rely on frozen glaciers. In the past 30 years, the temperature in the whole Arctic region has risen more than three times than that in other parts of the world, resulting in the melting and dissolution of a large number of glaciers, which has caused almost irreversible damage to the entire Arctic ecosystem. This is also the reason why there have been many large-scale cold waves in China this winter-because the Arctic Circle is slowly locking in cold air. With the continuous melting of glaciers, a large amount of cold air passes through Siberia and reaches China with ocean currents and ocean winds.
Therefore, global warming is a real fact. Frequent snowfall in the Sahara desert is also a chain reaction of global extreme weather caused by rising polar low temperature.
So is it wrong to say that the Little Ice Age predicted by scientists in the Daily Mail is wrong? In fact, it is hard to say that there is something wrong with scientists' predictions, because according to the solar cycle, 2030 will indeed enter a dormant period, and the minimum value may indeed bring about a global temperature drop from a natural point of view. However, this is a prediction of the environment without human intervention. In fact, frequent global human activities have changed the climate and ecology of the whole earth, which is why the world will continue to warm up rather than cool down when it should start to enter small glaciers in 2020.
So what do you think of this matter?
