The changes in the earth will become more and more serious in 2022. Extreme climate change is "wreaking havoc on the earth" and its impact on human beings is also increasing exponentially. However, this may only be a beginning stage for the earth.
is only in 2022, and many people have not thought of it. "Unprecedented" geothermal intensity has occurred in many areas around the world. According to normal thinking,
also developed slowly, rather than coming out all at once. Therefore, the extreme high temperature in 2022 has "subverted" many people's perceptions.
Why has the earth experienced such a strong change? What happened this year?
Everyone should not be surprised by the changes in the earth. After all, this is not the first time that the scientific community has explained this issue, almost every year.
But what? It seems that many countries have turned a deaf ear to it. The Paris Agreement has been in place for so many years, and many countries have joined it. But will there be much real change to the climate? Not much at all. The continued development of global warming continues.
According to the global average temperature data released in 2022, the global average temperature is 1.11°C higher than the pre-industrial level (average from 1850 to 1900). It is one of the seven warmest years since complete meteorological observation records are available, and this It also developed under the second consecutive "La Niña" phenomenon.
In other words, even if the global warming effect is "suspended" due to natural climate change, the temperature will still be higher. Therefore, the continued development of global warming is undeniable.
Therefore, it has become a fact that global warming will cause extreme climate, and climate phenomena such as high temperature will become more and more intense in summer.
According to a report released by the United Nations Agency for Disaster Prevention and Mitigation in 2020, compared with the previous two decades, the frequency of various disasters has increased significantly in the first two decades of the 21st century, with high temperature events increasing by 232% and heavy rains increasing by 134%. Storms of all kinds have increased by 97%, and China is also the country with the highest number of reported climate disasters.
So, it makes sense if we look at the high temperatures above 40 degrees in large areas in China during the summer. Because our country is also the country most severely affected by global warming, climate change this year has become more extreme.
However, under high temperatures, extreme drought, large-scale melting of glaciers and other problems are also occurring, which is not a good thing. Let’s just talk about the impact of climate change in our country alone.
Under high temperatures, the middle and lower reaches of the Yangtze River may suffer from continuous drought in autumn
In fact, high temperatures in 2022 are common. After the "route opening" between the subtropical high pressure in the northwest Pacific and the continental high pressure, large areas of my country have suffered from high temperatures. Influence. Therefore, throughout the Yangtze River Basin, extremely rare high temperatures have occurred in many areas. For example:
Poyang Lake A large area of lake beach is exposed at the mouth of the Yangtze River. The water level of the Yangtze River, which was originally the main flood season, continues to recede, resulting in the rare phenomenon of "reverse drying during the flood season."
The mouth of the south bank of Wuhan no longer has the surging river, but instead exposes a large beach. The waterfront platform on the river beach has no water, and the Yangtze River is not as majestic as it was during the flood season in previous years.
This shows that the drought in the Yangtze River this year is very obvious.
Therefore, the problems caused by the knock-on effects of the earth's climate can already be seen. Indeed, in previous years, the flood season was full of rain, but in 2022, it will be exactly the opposite. Not to mention the rainfall, the high temperature in many areas has been continuous for dozens of days. Therefore, drought is inevitable.
However, whether it is the upper reaches of the Yangtze River or the middle and lower reaches of the Yangtze River, the drought trend is difficult to eliminate.
According to the analysis of National Climate Center , the possibility of less precipitation in the Yangtze River Basin in autumn is still relatively high, especially in the middle and lower reaches, where there is a possibility of consecutive droughts in summer and autumn.
Fortunately, there are many water conservancy projects in the Yangtze River in my country. Therefore, the water supply guarantee rate for drinking water sources is over 95%, and it can reach 99% in cities and towns. The safety of drinking water for the people is guaranteed, so everyone can rest assured.
Earth’s climate change is so extreme, is there really no room for change?
In fact, although climate change in 2022 will be severe, it has not yet reached an "irreversible" situation for the overall climate model. According to the definition of the Paris Agreement, an increase of 1.5 degrees is humanity’s first climate change tipping point. Before "transcendence", there is still room for change.
However, this problem is quite serious. On the 2022 " World Earth Day ", the world is calling for the issue of "Earth's critical point" again.
As early as 20 years ago, The United Nations Intergovernmental Panel on Climate Change (IPCC) proposed that climate scientists have identified 15 tipping points that affect the balance of the earth system. Unfortunately, due to global warming, 15 of them will 9 have been awakened. In terms of quantity, it is already more than half.
At this time, humans need to make quick adjustments to deal with the next "critical point" changes. Otherwise, when these 15 critical points are completely "broken through", it will be difficult to make changes.
So, do you think there is still room for change? Indeed there is. But it depends on whether humans are willing to do it. Moreover, for global climate change, if everyone does not work together, it will be in vain. Discharging on one side and protecting on the other is never a balanced state.
Of course, we are not "crossing ourselves" here. On a global scale, China's efforts to maintain the ecosystem are still relatively strong. For example: Against the background of the overall reduction of global forest resources, China's forest area and stock volume have maintained "double growth" for more than 30 consecutive years.
data shows that about 1/4 of the world’s newly added green area from 2000 to 2017 came from China, with China’s contribution ranking first in the world. Statistics on forest coverage and in 2022 show that it has increased from 8.6% at the beginning of the founding of New China to 23.04%.
So, China has made the earth greener. China's contribution to global climate change is obvious. Without China's efforts over the years, perhaps the earth's ecosystem would be even worse. Therefore, let’s increase climate change. Humanity must work together.
