What is the root cause of sea level rise? How can we avoid the temperature rising?

Sea level rise is a global sea level rise phenomenon caused by global warming, melting of polar glaciers and thermal expansion of upper seawater. Since the 20th century, the global sea level has risen by 10-20cm, which is the best natural answer slowly emerging: the root cause is global warming. Sea level rise is caused by global warming, melting of polar glaciers and expansion of the upper ocean. The decrease of population, the loss of vegetation, the excessive emission of carbon dioxide and many other factors have led to the greenhouse effect, global warming, rising temperatures, and then glaciers melt and sea levels continue to rise, but the main reason for sea level rise is not the melting of glaciers. At present, the global average temperature rise is only 1. 1 degree, and global warming is limited, which leads to the global sea level rise.

Due to the warming of the climate, the temperature rises from the surface of seawater to a depth of about 2000 meters, which leads to the volume expansion of seawater. This has caused about two-thirds of the sea level rise, and only about 30% of the sea level rise comes from the melting of ice and snow. However, with the intensification of ice and snow melting in the future, its impact on sea level rise will be greater and greater. Sea level rise accumulates. At present, the rising speed of sea level is about 3 mm per year, and it will rise slowly in the future. If no measures are taken, it is estimated that the sea level will rise by nearly one meter by the end of this century. Don't think it is less than 1m, because when the sea level rises 1m, if there is a typhoon or astronomical tide, the sea level will rise a lot, and the water volume will increase sharply, which will have a very serious impact. It will slowly erode the coastline, which is also very serious.

In order to avoid the temperature rising, firstly, it is also a very important measure to use air conditioning in a civilized way. Air-conditioning compressor sends a lot of hot and humid air to the atmosphere, which will increase the heat. If it is installed in a ventilated yard, it must be placed as high as possible or on the roof. The air conditioner must be used with moderate low power to reduce the use time and avoid 24-hour operation. Use simple measures, such as fans and cold water to cool houses and reduce energy consumption.

Create your own green area, even if you only have room to grow a few pots of flowers, use it. Plants are the main heatstroke prevention drugs. In addition to providing shade, they will evaporate water into the atmosphere when breathing, thus significantly reducing the surrounding temperature. If you have a balcony or roof, please plant plants on it. The water used to water plants can be compensated by improving the urban landscape. If possible, you can install a green roof, do a good job of waterproof and load-bearing, and plant green plants on the roof, which can effectively reduce the indoor temperature. Don't join the traffic jam. Hundreds of cars with engines are parked together, and the heat wave is enough to knock anyone down. It is important to drive less and take air-conditioned public transport. Or use your favorite car or bike. If you travel by car, use air conditioning as little as possible.
