Does the ocean have a great influence on the climate?
The ocean plays a key role in atmospheric movement and climate change. The ocean current fitness exercise and the poor heating in the middle of monsoon paddy field agriculture have created unique natural scenery and various climatic conditions on the earth. For example, the North Atlantic warm current has brought beautiful ecological environment protection and excellent living habits to some Nordic countries, and the Asia-Pacific monsoon climate and the East Asian monsoon climate have brought stable drought to the agriculture of Southeast Asian countries.
According to Su Jingzhi, a researcher at China Institute of Meteorological Sciences, the ocean plays an important role in the global weather and climate management system, which can control the earth's climate, such as temperature and environmental humidity. Because of the great thermal inertia force of the ocean, the working capacity of storing heat on the same volume of sea surface is more than 2000 times that of air. If there is no ocean, the temperature difference between day and night, winter and summer on the earth will be very large, and the temperature fluctuation around will be very strong, which is probably not suitable for people to settle down.
According to information, the ocean contributes 90% of the precipitation and absorbs 90% of the unnecessary heat of the earth. Distribute heat to all countries in the world according to ocean currents, so that the earth will not keep warming or cooling. "The ocean also provides a lot of water vapor to the air. This rich water vapor makes the gas we inhale moist, otherwise it is not suitable for people to settle down. "
The ocean is still warming.
"Observing objective facts shows that the software of the earth's climate system is in a very sensitive equilibrium state at this stage."
Statistical analysis shows that since 100, nearly 50% of wetland parks in coastal areas have long been missing due to the comprehensive harm of glacier melting, climate warming and extreme climate. /kloc-since the 1980s, the ocean has digested and absorbed 20-30% of the carbon dioxide emitted by human beings, resulting in the continuous alkalization of the ocean. In recent decades, due to the acceleration of ice damage in Greenland and Antarctic ice sheets, the continuous destruction of glacier quality and the thermal deformation of the ocean, the water level has risen rapidly.
"Especially in 2020, although the global carbon dioxide emissions will be slightly reduced due to the pneumonia epidemic in COVID-19, the data information shows that in 2020, the global air pollutant consumption will increase, the global ocean will continue to warm, and the ocean fever will achieve new success."
What is even more worrying is that in the future, the abnormal water level rise in a large number of areas may be more frequent, and the increasingly frequent high water level will cause more serious harm to many areas. With the warming of the ocean and the decrease of sea ice, the global soil water content, yield and the development potential of aquaculture salvage of marine animal communities will decrease, and the population composition will also change; The risk of serious disasters such as the engulfment of bays and low-lying areas, bay floods and bay corrosion will increase.
Speaking of this, Su Jingzhi is very recognized. He showed that the ocean has been warming in recent decades, and it is widening from the surface of the ocean to more than 2000 meters in the deep sea. In recent years, the frequency of ocean heat has obviously increased, and the temperature of seawater has even increased by 4℃, and it has been rising for many months. "The seawater temperature has not changed much. If there are one or two fluctuations, the range will be great. Such a high temperature rise is extremely harmful to the marine green ecology, the survival of fish species and algae plants. "
"It must be emphasized that because the ocean has stored a lot of excess heat, and it is about 2000 meters deep. After decades and hundreds of years, this heat will continue to turn over the sea again. Considering that the surface temperature of the earth has risen a lot at that time, the heat of the ocean will cause the global temperature to rise twice, which will cause more serious harm to the global climate. The actual effect of this delay time of ocean heat should be highly valued. "
Authoritative experts call for more accurate observation of the ocean and a deeper understanding of the climate login code of the ocean, which seems to be more critical than ever before. At the same time, the masses should actively understand the key role of the ocean in the software of the earth's climate system, reduce the emission of atmospheric pollutants, and take the development trend of green, low-carbon and environmental protection.
