The summer of 2022 May is the hottest in the history of meteorological observations.
Since June, a large range of Chinese heat waves have been overwhelming, wave after wave with a more ferocious situation spreading. The central meteorological station has continuously issued the national red warning of high temperature, enough to see the seriousness of the heat wave.
So far, the whole country has seen high temperatures except Heilongjiang, with 28 provincial-level administrative regions seeing temperatures of 40 degrees Celsius and 26 regions breaking record high temperatures.
China is not the only country in the heat wave, the heat is the same all over the world, and some places are even worse than China, with the temperature reaching 50℃ 39bet-xsmb-xổ số tây ninh-xổ số binh phước-xổ số binh dương-xổ số đồng nai. Many areas are suffering from heat stroke and death due to the high temperature. Spain is particularly serious, and the wildfires caused by high temperatures and dry conditions have killed more than 1,000 people.
Cooling the Earth, it seems, has become an urgent matter.
A recent article in Nature Foods, one of the world's leading scientific journals, describes some of the consequences of a nuclear war today. The world is in such a state of flux that nuclear war no longer seems a distant problem. The article offers not only the possible effects of nuclear war, but also the promise of a climate change that could immediately cool the planet into a Little Ice age.
With global warming on the rise, it would seem a good thing if the planet could be cooled down a bit. But to the average person, the mere thought of nuclear weapons can make one shudder. How did nuclear bombs, as weapons of mass destruction, lead researchers to think that they might be a way to cool the planet?
Since the beginning of mankind, there has been an issue: How to deal with the relationship between human beings and nature, this year's heat wave across the world, in the final analysis is the evil result of global warming, the United Nations Intergovernmental Panel on Climate Change released the sixth assessment report in August 2021, the report pointed out that the global warming in the last 50 years is happening at an unprecedented rate in the past 2000 years.
As the global average temperature continues to rise, this year's extreme high temperature may become the norm in the future. As the direct exposure of the global climate environment, the cities inhabited by human beings will naturally be affected by continuous global warming.
This year's heatwave was not a surprise, but one that began in 2021, when the global average temperature was 1.11 degrees Celsius above pre-industrial levels, making it one of the warmest years in complete meteorological records, according to publicly available data from the United Nations.
1.11 degrees Celsius may seem inconsequential, and we won't even feel the temperature change at this point, but Johann, director of the Potsdam Institute for Climate Impact Research. Dr. Lokstrom has come up with Hothouse Earth, which states that if the Earth's average temperature rises by more than 1.5 degrees Celsius compared with pre-industrial temperatures, the greenhouse effect will be irreversible.
The melting of Siberian permafrost will also produce methane, which is 25 times more potent as a greenhouse gas than carbon dioxide. Venus is the poster child for extreme greenhouse warming, which makes up most of its atmosphere, and global warming will lead to the disappearance of the Amazon rainforest.
Plants not only produce oxygen through photosynthesis, but also trap carbon dioxide from the atmosphere to the surface. The Amazon rainforest is known as the lungs of the Earth. If it disappears, it will release all the carbon dioxide stored for hundreds of years into the atmosphere, further accelerating the greenhouse effect.
By then, no matter what human efforts are made, the amount of greenhouse gases cannot be reduced any more, and the Earth will reach the dangerous level of "+4℃" in only a few hundred years.
Therefore, to prevent global warming, can be said to be a matter of human survival, but industrial production, human development, reducing carbon dioxide emissions is not easy? So some people thought, since we can't cut greenhouse gas emissions, we might as well cut the amount of heat the Earth receives.
When a nuclear bomb explodes, it creates a lot of smoke and dust. Especially in the cities and industrial zones to detonate, soot volume will be bigger, the dust will float to the stratosphere, and along with the spread of global circulation to all parts of the world, they will block the sun, greatly reduce the heat of the sun to the earth, the researchers to simulate the six different bomb scenes, each time will be injected into the stratosphere varying degrees of soot, the results of every kind of cause of climate change.
In the first month after a bomb blast, global temperatures will fall by about eight degrees, it will trigger further ocean temperatures drop, expand the range will be more than 600 square miles of sea ice. Even decades later disappear for dust in the stratosphere will still exist, the sea ice in the arctic sea ice is likely to continue to develop even thousands of years.
In this way, a nuclear bomb would seem to be a real solution to global warming. But the solution is quick, and the cost is unbearable. The study estimates that in a week-long global nuclear conflict, about 360 million people would die directly from nuclear bombs.
A nuclear bomb would pour 150 million tons of soot into the stratosphere, reducing global heat production by 90%, making crops unviable, and killing an estimated 5 billion people from famine two years after a nuclear conflict.
So what looks like hope is, in fact, the path of human self-destruction. Global warming is not built in a day, and the solution to this problem naturally needs to be taken slowly and step by step.
