How serious is global warming?

According to the latest satellite detection data, NASA climatologist Zwali said, "At this rate, by the end of the summer of 20 12, the Arctic Ocean will be almost completely ice-free, much faster than previously expected". This will be devastating to human civilization. Our situation is very critical, leaving us very limited time to turn things around. Only by taking effective measures quickly can human beings survive. James hanson, chief climatologist of NASA, known as the godfather of global warming, said, "We have passed the critical point, and we have not passed the irreversible critical point. We can still reverse the situation, but we need to change our direction quickly." Compared with some symbolic changes and slow policies, I appreciate the American scientist Dennis meadows, the author of The Limits to Growth, who pointed out that "the root cause of global warming is the excessive greed and consumption of materials by human beings". In order to control global warming quickly, we must change the production and lifestyle of mass production and consumption since the industrial revolution and reduce all unnecessary consumption. Its core and purpose is to form an economical lifestyle, reduce energy consumption and reduce greenhouse gas emissions. Among all substantive and concrete measures, the most effective measures are vegetarianism and giving up meat, because meat is a carbon-intensive product, followed by walking as much as possible and relying on public transportation, reducing motor vehicles and saving energy and electricity. As Pachauri, chairman of the United Nations Intergovernmental Panel on Climate Change, advocated, mankind can save the earth and itself: eat less meat, ride bicycles and live frugally. These measures to slow down global warming can be done by everyone, and the survival of mankind is in everyone's hands, which requires each of us to shoulder our own responsibilities and take practical actions instead of being indifferent.

How far is the disaster caused by global warming from us?

The fourth climate change assessment report issued by the United Nations Intergovernmental Panel on Climate Change (IPCC) in Valencia, Spain on June165438+1October 17, 2007 pointed out that the warming of the climate system is a "clear" fact, and human activities should be responsible for 90%.

In fact, in recent years, almost everyone has personally felt and experienced climate warming: warm winter, early summer, typhoon, flood, drought, high temperature in summer … ..

In the summer of 2006, the continuous high temperature and drought in Sichuan caused more than 3 million people in Sichuan Province to have difficulty drinking water due to drought, and the crops failed and the direct economic loss was 7.03 billion yuan. In the summer of 2007, extreme weather events hit all parts of the world. In Europe, the unprecedented high temperature in Hungary killed 500 people in a week, and Britain suffered the worst flood in 60 years. In the United States, when the weather is clear, huge ice cubes weighing 25 kilograms fall from the sky; In Southeast Asia, due to rising temperatures and increasing rainfall, the number of dengue cases in Indonesia and Singapore has nearly tripled compared with the same period last year. ...

These are just the beginning of disasters caused by climate warming. The most sensitive to global warming are the Arctic and Antarctic, where glaciers and ice sheets are melting. The warming rate in Antarctica is three times that of the global average. As the sea warms, the Antarctic ice circle begins to melt, and once it partially melts, the global sea level will rise; The situation in the Arctic is even worse. Since 1970, the thickness of the Arctic ice circle has obviously decreased, and it has decreased by 40% in the past 40 years. In the past five years, the rate of glacier melting in Greenland has doubled. It is estimated that if the whole Greenland ice sheet melts, the global sea level will rise by 7 meters, which means that the whole Florida or Bangladesh will sink to the bottom of the sea. If the entire Antarctic ice sheet melts, it will be even more terrible, when the global ocean surface will rise by 65 meters.

What does the melting of glaciers and ice sheets mean?

The ancient virus released by floods and glaciers will become a terrible disaster. ...

The melting of glaciers and ice sheets not only means that human beings will face catastrophic floods and climate disorder, but also the viruses sleeping in glaciers will be released with the melting of glaciers, leading to the spread of diseases. ...

Recently, American scientists have discovered that some glaciers contain virus strains that may cause the spread of diseases.

Researchers have found that there are many viruses hidden in the melting ancient ice layer, such as all kinds of weird influenza viruses, bone marrow gray matter viruses, smallpox viruses and so on. There are many other types of viruses that have not been confirmed. Ancient microorganisms sleeping in glaciers may be released with the melting of glaciers, which will bring more terrible disasters to human beings who have no resistance to them.

Arctic sea ice will reflect 80% of solar heat energy, sea ice will disappear, and 80% of heat energy from the sun will enter the ocean. Warm seawater will accelerate the melting of ice and form a vicious circle. Ocean warming will release natural gas in the ocean, which will make people poisoned by excessive natural gas in the air. ...

Perhaps the disasters caused by melting glaciers and ice sheets are not only floods, disease spread and natural gas poisoning, but these alone are enough to destroy human civilization. ...

There will be no ice in the Arctic in the summer of 20 12.

Just last year, scientists warned that at the current rate of global warming, Arctic ice would melt in the summer of 2040, when there would be no ice at all. Now, new research has found that the ice in the Arctic is melting much faster than previously predicted, and the above situation may appear as early as 20 12!

According to the latest satellite detection data of NASA, the amount of Arctic sea ice at the end of this summer is only half that of four years ago. The melting speed of the Arctic makes scientists worry that global warming has reached a critical point. Serizhe, a senior scientist at the National Snow and Ice Data Center, said, "The Arctic is shouting. 」

After reviewing the latest NASA, "At this rate, by the end of the summer of 20 12, the Arctic Ocean will be almost completely ice-free, which is much faster than previously expected. ぃ 1 q9 a； l 1 w“| 3 ebbs.toenergy.org”

Han Sen, the chief climatologist of NASA, known as the godfather of global warming, will announce that according to the melting of Greenland glaciers, the earth has reached the so-called critical point of global warming. In an e-mail interview, he said, "We haven't reached the point of irretrievability. We can turn back in time, but we need to turn around quickly.

News source Dongsen News (2007/ 12/ 12):

Changing lifestyle and slowing down global warming are things that everyone can do.

The survival of mankind is in everyone's hands, and we need everyone to take practical actions to change our way of life and slow down global warming.

On Tuesday, Pachouri, chairman of the United Nations Intergovernmental Panel on Climate Change, put forward an ingenious plan for mankind to save the planet:

Eat less meat, ride a bike and live frugally.

According to the United Zaobao.com News Agency, Pachouri said at a news conference that the climate change report released by the Committee last year emphasized "the importance of changing lifestyles". He said: "The Committee didn't dare to say it before, but now it has to say it."

The economist from India called on people all over the world to curb their desire to eat meat. He said, "Please eat less meat, which is a carbon-intensive product". Eating too much meat is harmful to your health. "

Early research found that for every 65,438+0 kg of meat produced, 36.4 kg of carbon dioxide would be emitted.

In addition, the energy required to raise and transport 1 kg of cattle, sheep and pork can light a 100 watt light bulb for three weeks.

When enumerating the contributions that individuals can make to the fight against global warming, Pachouri paid special tribute to Paris and other French cities, which launched the community bicycle enjoyment program, which was a "remarkable arrangement".

He said: "Instead of driving 500 meters, it is better to ride a bike or walk, which will make a bigger difference."

He also said that another lifestyle that can be changed is shopping, which also helps to reduce the degree of climate change. He wants people to buy only what they really need, not "when they see something for sale".

Since the Nobel Committee awarded the Peace Prize to the Climate Change Committee and former US Vice President Al Gore in June 5438+ 10 last year, Pachouri has been running around the world to speak out for the danger of climate warming.

He warned on Tuesday: "The reality is cruel. If humans do nothing, climate change will have a huge impact. "
