"China Climate Change Blue Book (2022)" is officially released! See again – the Earth's climate change is "getting worse". It can be said that there is not much time left for humans to change the earth's climate.
Many people should also experience first-hand that in the context of global warming, there are various extreme climate phenomena in the world, and these climate phenomena are "fatal" effects, and people in many areas have died due to high temperatures.
For example, in 2022, many parts of northern, western and eastern India all experienced temperatures exceeding 40 degrees Celsius, experiencing unprecedented heatwaves of climates that lasted long and were intense. According to preliminary statistics, nearly 100 people have died due to extreme heat weather, so the extreme high temperature has a very large impact on humans.
However, through the data of the "China Climate Change Blue Book (2022)", it is once again shown that the climate change of the earth or China is constantly evolving and becoming more and more severe, and at the same time, the things that human beings are most worried about may happen, which is not "alarmist", but a real event under climate change. What the hell is going on?
China is getting hotter!
First of all, we need to know that rising temperatures on the mainland are in tandem with global climate change, because the effects of global warming are "global" and not targeted at any one region.
According to monitoring data, in 2021, the global average temperature was 1.11°C higher than the pre-industrial level (1850-1900 average) and became the hottest of the seven years on record. You know, in 2021 there is also what we call the "pause in global warming" effect.
Because last year our atmospheric phenomenon, La Niña, developed, it will trigger a pause in global warming, with a temporary "climate mitigation" effect.
However, in this case, no global warming has been reversed out of one of the "hottest" years, and you can imagine that the development of global warming is indeed not to be underestimated.
At the same time, under the global average temperature of the past 20 years, there is also a higher than the industrialization level of 1.01 °C. The average surface temperature in Asia is 0.81°C alone, the seventh highest since 1901.
So, it can also be known from here that China has become hotter, because China is also a major sensitive area for global warming. According to china's climate data, from 1951 to 2021, the average annual surface temperature in China showed a significant upward trend, with a warming rate of 0.26 °C/10 years, which was higher than the global average warming level (0.15 °C/10 years) in the same period.
The past 20 years have been the warmest period in China since the beginning of the 20th century, and in 2021, the average surface temperature in China is 0.97 °C higher than the normal value, the highest value since 1901. See? 120 years of the strongest, China has indeed become hotter, the data says it all.
Of course, heat is not to mention, even in some parts of the mainland there is still a situation of less rainfall, mainly rainwater "uneven distribution", in 1961 to 2021, China's average annual precipitation showed an increasing trend, an average increase of 5.5 mm per 10 years, since 2012 the annual precipitation has continued to be more.
In 2021, China's average precipitation is 6.7% more than the usual value, of which the average precipitation in North China is the highest since 1961, while the average precipitation in South China is the lowest in the past decade. Therefore, the rainfall in South China has become less, as a perennial high temperature zone, there is less rain in South China, which is indeed not a good thing, and climate change is really too serious.
The earth's climate has changed, and human time is really running out
Although in recent years, human beings have increased the change of climate, but we have not seen great results, and we have not only not seen the climate easing, but has become more serious.
First of all, we need to explain that China's climate efforts can be said to be very strong.
For example, China's dependence on carbon has fallen by more than half over 10 years, with coal accounting for more than 70 percent of total energy consumption in 2009 and falling to about 57 percent by 2020. The contribution this makes to the planet's greenhouse gas emissions cannot be ignored.
In addition, China's greening of the earth can also be seen, and China's determination to change the climate.
In 2019, the journal Nature published data showing that between 2000 and 2017, satellite data showed that the vegetation area of the Earth continued to expand, of which China's green area increased by 42%, and it was entirely an increase in forest area. Of course, the 2022 data also proves this problem again.
The overall vegetation cover in China has increased steadily and shown a trend of greening.
Among them, in 2021, China's average NDVI increased by 7.9% from the average in 2001 to 2020, and by 2.5% from the average in 2016-2020, the highest value since 2000.
So, China has made the earth greener. So why haven't climate changes reversed yet? In fact, we only see the change in China here, but we don't see all the countries in the world changing together.
For example, Brazil continues to deforest tropical rainforest, according to Brazil's National Institute of Space Research, from January to June this year, 3988 square kilometers of deforestation in the region. That's up 10.6 percent from the same period last year and the highest level since the agency began compiling the data in mid-2015.
You say, can the Earth really change? While planting and cutting, both are affecting the earth's climate. So, if we don't make changes together, there's no "mitigation." A single force cannot meet the requirements.
So, we see ourselves ramping up climate maintenance. However, many other countries have not, but have increased the destruction, and the earth's climate will only be more severe, not better.
Of course, afforestation and reducing greenhouse gas emissions are only part of it, just look at it here. But overall, the Earth's climate change has been very serious, and human time is really running out.
In 2019, the British journal Nature, the United Nations Intergovernmental Panel on Climate Change (IPCC) issued a warning against the "tipping point" of the Earth's 1.5 degree rise, if the global warming cannot be controlled within 1.5 degrees Celsius, the Earth will face a devastating climate after 2030, and human society and ecosystems will be affected.
According to the IPCC's assessment at the time, the time left for mankind was only 12 years, which is already 2022, and another 3 years have passed, which shows that there is really not much time left for humans to change the climate, that is, 9 years.
So, hurry up and respond to the changes in the earth's climate, maybe it's less than 9 years, and it all has changed. However, against the backdrop of global warming, more problems are constantly emerging.
The most feared ones may happen
What's the matter? Nothing seems to be going on except for the problem of extreme weather phenomena? In fact, it is not, the chain effect under the climate performance is stronger, and the most worrying thing for human beings may happen - the most critical point is what we call the problem of ancient germs.
As we all know, under global warming, more and more ancient bacteria are emerging, and in 2022, Nikolay Korchunov, a senior official of the Russian Arctic Council, said that the thawing of permafrost caused by global warming may lead to the "awakening" of ancient viruses and bacteria, posing an extreme threat to human beings.
Because French and Russian researchers have previously found two new giant prehistoric viruses in permafrost samples. One of the viruses, called Molivirus sibericum, has been dormant for 30,000 years, but can be revived immediately after thawing and exposing it to its host, the amoeba.
At the same time, the Arctic Report has also speculated that eradicated diseases such as smallpox or the Black Death may be frozen in permafrost. And the continuous increase of global warming will accelerate the appearance of these ancient bacteria and viruses on the earth, which is what human beings are most worried about.
And many unknown viruses are also sealed underground, deadly or not deadly.
Once they are released on a large scale with the earth's climate, then the "virus invasion of the earth" that humanity is most worried about and most afraid of may appear.
At this time, the survival of life on the earth may face a crisis. Therefore, global warming continues to develop, and the most feared by human beings may occur, and this trend is becoming more and more obvious.
