What is the impact of "high fever" for four consecutive years on the earth?

After the global annual average temperature record was set for three consecutive years from 20 14 to 20 16, the earth's high fever did not improve in 20 17, and it still "burned" badly, ranking among the top three in the history of modern meteorological records.

The noise around climate change keeps coming and going, but no one can ignore the signal of the earth: the global land and sea temperatures have hit record highs, leading to a record high sea level and a sharp increase in extreme climate frequency. ...

Experts warn that the earth's "high fever" for four consecutive years shows an unprecedented sense of urgency to deal with climate change, and no country should and cannot be immune to this challenge of mankind.

Recently, the World Meteorological Organization, the National Oceanic and Atmospheric Administration, the National Aeronautics and Space Administration, the British Met Office and many other institutions released the global temperature report for 20 17. The analysis methods and data of each family are different, but the conclusion is very consistent, that is, the past year ranked second or third in the history of meteorological records, continuing the long-term trend of global warming.

"There are only a few places where there is a' net cooling', and besides, the whole world is getting warmer," Gavin Schmidt, director of the Goddard Institute of Space Studies of NASA, said at a telephone news conference jointly held by NASA and the National Oceanic and Atmospheric Administration on 10/8. "Basically, all the climate warming in the past 60 years can be attributed to human activities, and the culprit is

It should be pointed out that, unlike the persistent strong El Ni? o phenomena of 20 15 and 20 16, there is no El Ni? o phenomenon that drives the global temperature in 20 17, but a weak La Ni? a phenomenon that leads to cooling. All institutions agree that if La Nina is excluded, 20 17 will be the hottest year since 1880.

According to the goal set by the Paris Agreement, which embodies the most extensive knowledge of the international community in dealing with climate change, the global average temperature should be controlled within 2 degrees Celsius compared with the pre-industrial level, and efforts should be made to control the temperature rise within 65,438 0.5 degrees Celsius. However, the latest data show that in the past 100 years, the average temperature of the earth's surface has increased by more than 1 degree Celsius. Last year was the third consecutive year that the global temperature was higher than the level at the end of 19 by 1 degree Celsius.

Some climate experts predict that if the current warming rate continues unchecked, the global temperature may cross the target of an average increase of 1.5 degrees Celsius in the next 20 years, and will soon cross the red line of an average increase of 2 degrees Celsius.

Some people think that it is doubtful whether global warming is caused by human activities, even if it is, it is not important. They believe that the world can continue to follow the previous dance steps and embrace "past" energy sources such as coal and oil. Is this really feasible?

Common sense tells us that we can't bet on human survival and long-term development.

The 2007 climate change assessment report of the Intergovernmental Panel on Climate Change, which is attended by nearly 3,000 scientists around the world, believes that the earth is warming and will have a significant impact on the environment. The fifth assessment report of the agency 20 14 clearly pointed out that the influence of human beings on the climate system is becoming more and more obvious.

The standard of climate change is the increase of extreme weather frequency, and hot summers, violent hurricanes and catastrophic floods have gradually become "frequent visitors", such as the increasing tornadoes in North America, persistent floods and droughts in Asia and so on. The climate model of the World Meteorological Organization shows that these anomalies are related to global warming. The greater the human disturbance to the climate, the higher the risk coefficient that human faces. Treating these studies as a conspiracy will only mislead people's efforts and make the problem worse.
