It is imminent to deal with global warming. It is time for everyone to put it as soon as possible.This is the information conveyed by an important report released by the UN Intergovernmental Climate Change Special Committee (IPCC) the day before yesterday.The world can now clearly see the consequences of global warming 1 degree Celsius, including more polar climate events, sea level rising, and the ablation of the Arctic sea ice.
This report was invited by the IPCC in the Paris Climate Agreement in 2015 and was invited by the United Nations Framework Convention on Climate Change.According to the agreement, nearly 200 countries around the world agreed to increase the global average temperature increase to control within 2 degrees Celsius of the previous industrial level, and to pursue no more than 1.5 degrees Celsius.In other words, at most, it only increases by only 0.5 degrees Celsius.
This seems to be a very difficult goal.The reason why the problem is particularly urgent now is that the report states that if countries around the world only develop in accordance with the emission reduction commitment made in the Paris Climate AgreeBy 2100, 3 degrees Celsius.And once the warming increases to 2 degrees Celsius, the sea level will rise by about 10 cm.my country's second national climate change study predicts that by the end of the 2100 this century, the average sea plane around my country may rise by up to 1 meter.
Therefore, 91 scientists from 40 countries analyzed more than 6,000 scientific materials that if they need to control the temperature increase within 1.5 degrees Celsius, it must beThe level was reduced by 45 % and it was reduced to zero by 2050.This means that all levels of society must have changed unprecedentedly, especially the energy industry must carry out tremendous reforms.
Most people may be difficult to understand, how can the change of 0.5 degrees Celsius or 1 degree Celsius affect our earth.Now experts tell us that increasing half -degree Celsius may increase sea levels by 10 centimeters, which affects the influence on Singapore and many other islands, as well as large cities or ports in the sea, and many low -lying areas are likely to be drowned by seawater.One of the main measures that can stop this situation is to reduce emission reduction.
It is regrettable that the world's largest carbon emissions country in the world in President Trump has rushed out of the Paris Climate Agreement, which has caused the US government to respond to climate change from the time of the former Vice President Gore.EssenceFortunately, the United States still preserves a power to keep the climate agreement. For example, many governors have claimed that they will continue to work hard to reduce emission reduction.
The importance of keeping the promise in various countries (especially the discharged powers) is self -evident.This must greatly adjust the energy structure.At present, coal power generation accounts for about 37 % of the global energy market, about 25 % of renewable energy, and 24 % of natural gas.The suggestion made in the report is that the proportion of renewable energy was increased to 70 % to 85 % by 2050, and the proportion of natural gas was reduced to 8 %, and the ratio of coal power generation was reduced to 0 % to 2 %.Although the global investment in low -carbon energy technology may be as high as 2.4 trillion US dollars each year, it is obviously the best choice to accelerate the development of low -carbon new technology.
But the responsibility for emission reduction is not only in the government, but also played a very important role.However, most people may not understand what role can individuals play in dealing with the work of the earth.In fact, the importance of individual characters is no less important than the government.Another point that the report emphasizes that changing life and consumption habits is closely related to individuals.This includes reducing energy consumption in daily life, changing power -saving electrical appliances, and changing travel methods, such as reducing the use of private cars, changing public transportation, walking or riding a bicycle.In terms of personal consumption, people can reduce eating beef and mutton. This is because the breeding of beef needs a lot of water, and cattle and sheep will emit a large amount of greenhouse gas methane.
Today, the temperature of the earth's temperature is nearly 1 degree Celsius before the industrial revolution, which has a wide range of climate changes, has a wide range of influence and great destruction, and it can also be witnessed or personalized by the world.It is difficult for us to imagine what a more terrible greenhouse effect will bring in the temperature of the temperature, but it is certain that all mankind will be harmed.Therefore, it is not just the responsibility of each country, but also the responsibility of everyone.
