Whether we admit it or not, extreme weather caused by climate change is happening on the earth. The suitable climate environment enjoyed by the earth's creatures may be slowly disappearing, and the culprit is human beings themselves!

Whether we admit it or not, extreme weather caused by climate change is happening on the earth. The suitable climate environment enjoyed by the earth's creatures may be slowly disappearing, and the culprit is human beings themselves!

Life on earth has a history of development and evolution of 3.8 billion years. According to current knowledge, more than 20 species extinction events, large and small, have occurred on the earth in the last 500-600 million years, with a total of 5 large-scale events. times, almost all of which resulted in the disappearance of more than 80% of species at that time. Except for the fifth mass extinction event, which was caused by the impact of an asteroid with a diameter of 10 kilometers on the earth, causing the extinction of the dinosaurs, the first four species extinction events are all related to changes in the climate and environment.

It has been 65 million years since the last mass extinction event. So whether or when the next mass extinction event will occur may be a question that humans need to study and consider!

In recent times, many places at home and abroad have been shrouded in "heat". Extreme high temperature weather means less rain, and reduced precipitation means drought. According to a report by the British Broadcasting Corporation (BBC) on August 19, with the continuous With high temperatures and little rain, many European countries are facing severe drought. On the 17th local time in Germany, a citizen discovered the "Hunger Stone" on the shore of Reindorf.

Similar stones can be found in many European countries. For example, a stone found on the bank of the Elbe basin in the Czech Republic has the words "Just wait until you cry when you see me"!

What is the "Hungry Stone"?

Many people feel baffled and feel a sense of fear when looking at the various warnings recorded on the "Hungry Stone". Are these all curses and ominous omens?

In fact, the so-called "Hungry Stone" is far from as mysterious as we imagined. Human beings have lived by water since ancient times, and the earth's climate environment is not constant, whether it is floods or droughts. common.

When there is a drought year, the water level in the river will see the water level decrease, and even the flow will stop. Whether it is flood or drought, it will cause human beings to lack food and clothing. Especially in the ancient disaster years, it was very common for people to die of hunger on the road. , everyone naturally cried when they were hungry.

When the river dies and the stones in the river gradually appear, some people may leave some warning sentences on the stones, such as "You will cry when you see me", because in normal years, the river The flow will not stop, so naturally the stones at the bottom of the river will not be visible.

The appearance of the "Hungry Stone" is not mysterious. The reason is also very simple: high temperature and lack of rain

2022 is destined to be an extraordinary year for mankind, especially the frequent occurrence of extreme weather caused by climate change, which is already affecting our lives. daily life. Especially since July this summer, the subtropical high has been extremely strong, causing high temperature weather to sweep across many countries.

html Since July, many European countries have experienced a once-in-a-century boom. The temperature in many places has exceeded 40°C, breaking historical extremes. For example, the highest temperature of 40.3°C in Corningsby, Lincolnshire, England, is a British record. highest value since.

The heat wave that hit the northern hemisphere this time is mainly related to the powerful subtropical high pressure. They circle the earth and bring widespread and sustained extreme high temperature weather under the influence of multiple factors.

We all know that the Netherlands is a country with very developed river systems. In the past hundred years, their main work has been to control flood disasters, because more than half of their land is flood-prone areas, but that's it A "water conservancy kingdom" also suffered from drought this year, causing water levels in its rivers and lakes to reach record lows.

In 2021, North America encountered record-breaking extreme high temperature weather, and many places broke historical high temperature records one after another.

The highest temperature in Canada was close to 50°C, and the highest temperature in the United States once reached 47.2°C.Extreme hot weather has caused casualties, and similar hot weather will appear again in 2022!

This season should be the flood season in southern China. Some places will experience plum rain weather, but this year is quite abnormal, ushering in high temperature and drought!

The continuous high temperature weather has also brought about a series of chain reactions. The Yangtze River basin has begun to dry up, and many rivers have experienced drying up. Especially in Sichuan, Chongqing and other places, high temperatures of 40+ and 50+ have occurred one after another. According to According to the notice of the Central Meteorological Observatory, the National Climate Center has passed monitoring and evaluation. The comprehensive intensity of regional high temperature events since June 13 is the strongest since complete meteorological records (1961).

Large-scale, high-intensity, long-lasting high-temperature weather will also bring us many secondary disasters, such as heat stroke and heat stroke. The situation has increased significantly. On the contrary, in northern my country, we have experienced intensive rainfall. , the country as a whole shows a situation of drought in the south and floods in the north.

said that in the end

in fact, the occurrence of extreme high temperatures is relatively rare but not accidental. We often see remarks about the increase in global average temperature under the influence of the greenhouse effect, but we have never experienced it personally. Recently, extreme high temperatures have occurred frequently this year. We are already experiencing the extreme weather caused by climate change!

and The culprit of the greenhouse effect is human beings, who can't get rid of them even if they want to. Over-reliance on fossil energy and excessive cutting of vegetation are the main reasons for the release of greenhouse gases and the intensification of the greenhouse effect. The earth is the home of millions of species. We can say that the earth is our home, but the earth definitely does not only belong to humans. We don’t need to think about whether the sixth mass extinction of species will come. We just need to know that continued extreme weather will eventually lead to serious consequences!
