Scientific rambling
The era of global warming has passed, and the era of global boiling has arrived. ”
"Boiling Times".The word isGlobal warmingThis grim situation provides a new interpretation, and through the definition of the "boiling age", people can clearly feel that the earth's climate is gradually becoming extreme, which will be a warning to all mankind.
2023 already isExtreme weather is frequentCould 2024 get worse?
In fact, global warming is already a "cliché" topic. The concept was first proposed at the end of the 19th century, and scientists believed that the Earth's atmosphereElevated carbon dioxide concentrations, can be madeThe temperature on the Earth's surface is rising。Moreover, after this concept was proposed, it was not until the 50s of the 20th century that people gradually realized the threat posed by global warming to the earth.
At the same timeEl NiñoContinue to intensify. El Niño caused an anomalous increase in sea temperatures in the eastern equatorial Pacific Ocean. The El Niño phenomenon has a great impact on the climate and environment, and it mainly bringsHeatwaves, droughts, floods and typhoons weakenedand other climatic phenomena.
Let's look at the intensity of global climate change with more specific data. Last year's June, July and August were considered the three warmest months in Earth's history. During this time, heat waves of varying degrees have swept across the globe.
During these three months, the average global temperature was reached16.77 degrees Celsius, is historicalThe highest record。At the same time, the high temperatures of this summer are becoming more and more apparent. Many regions of the globe have experienced it40 degrees CelsiusEven50 degrees CelsiusThis is further evidence that extreme weather is spreading across the globe.
My country has faced similar challenges. According to the statistics,Last yearIn summer, the average felt temperature during the day in 34 cities in China exceeded the average average of 2°C, which mainly occurred in North China and Northwest China. From this point of view, the development of the phenomenon of high temperatures is becoming more and more intense.
The phenomenon of "the earth boiling" has become very obvious, and if the climate continues to be in this state, humanity will face even more serious challenges in the future. The problem is not just about the high temperature conditions caused by "boiling", but more about itDrought, rainfalland other ongoing climate change.
In 2023, this trend continues to strengthen, so for 2024, it could be a catastrophic year with high temperatures. Among them, the El Niño phenomenon in 2023 continues to evolve. 2023 is not the year when El Niño is at its most impactfulThis phenomenon generally occurs every 2 to 7 years and usually lasts 9 to 12 monthsIt will have a bigger impact on 2024.
In addition, under the increasing trend of global warmingClimate tipping pointsThe breakthrough has also become stronger.
Currently,Nine of the world's 15 "climate tipping points" have been activated。After 2023, there are more than nine climate tipping points that could be breached. So, what does a breakthrough in the climate tipping point mean? What impact will it have on humans?
A climate tipping point is a sudden change point in climate change, and it isIrreversibleof,Once the tipping point is breached, the system will never be able to return to its original stable state. Moreover, tipping point events are difficult. There is no way to know the specific trigger point. Climate tipping point events are generally of a large scaleIf it happens, it will affect the whole world or a large region, and if triggered, it will have a devastating impact on the climate.
As global temperatures rise, the climate system is getting closer to a tipping point. If the global temperature rises by 15 degrees Celsius, which could trigger 4 critical points and put another 5 into the danger zone; IfGlobal warming reaches 2above, more tipping points will be triggered.
Therefore, when one climate tipping point is triggered, it may push the Earth's atmospheric system to invert to another tipping point, likeDominoesamplify the impact on the climate as a whole. Due to the sheer scale of the climate tipping point itself, it is extremely difficult to stop the entire dominoes from falling once they occur. This will bring irreversible or even devastating disasters to the atmospheric environment, human beings and biological systems.
The global warming trend is intensifying, causing the average temperature of the earth to continue to rise. At the same time as the temperature rises, due toHuman activityThe anthropogenic warming caused by this is also increasing rapidly. This trend of rising temperatures has led to:Sea level rise and glacier retreatand other extreme weather events.
The melting of glaciers poses a threat to the survival of life in the polar regionsAt the same time, the living environment of coastal dwellers has become precariousTo a certain extent, it affects the sustainable development of social economy and the quality of life of the people.
In 2023,Typhoons, droughts and floodsThe frequent occurrence of extreme weather events has brought permanent damage to the environment inhabited by humans.
At present, the earth has broken through some of the tipping points, and the tipping points that have not been broken are also in a dangerous state. If these tipping points are fully breached, then the Earth is entering almost"State of Death"., the probability of wanting to change the state of the earth is basically zero. Therefore, humanity should take measures to cope with the current drastic climate change, and not let every subsequent year become"Year of disaster".
At present, many measures have been taken to slow down the process of global warming. The most important of these is:Emission reduction and low carbon。First, reduce the total consumption of fossil energy in various waysUse new energy sources such as solar energy, hydropower, and wind energy as much as possible to reduce carbon dioxide emissions; Secondly, toProtect existing forests, because vegetation is very importantCarbon sinks
In order to cope with global warming and respond to low-carbon and energy-saving, China proposed 2030 in 2022"Carbon peaking".with 2060"Carbon neutral".goals. So what can we, as ordinary citizens, do in our daily lives?
In fact, we can start from all aspects of clothing, food, housing and transportation, such as practicing green travel and practiceCD-ROM action, saving electricity, doing a good job of garbage sorting, and reducing single-use plastic bagsand so on. Today's tiny gesture could all make a difference to protect our planet.
In short, climate change is a very representative problem on a global scale. No country is immune to the devastating consequences of climate change. At the same time, facing the challenge of climate change requires a global effort. Therefore, in the face of the global warming crisis, humanity must work together to protect our planet.
