Is 202 1 a high temperature year?

202 1 is a high temperature year. According to experts' prediction, the national high temperature forecast this summer is around 35 degrees, the highest temperature in some parts of the south is above 40 degrees, and the national average summer temperature is around 18℃~ 28℃, but the weather forecast is the main one.

The hottest day in summer is 2-3 pm. At this time, although the sun sets in the west, the altitude angle is still very large, and the heat stored on the surface is still greater than the heat released, which makes the temperature continue to rise, the local surface heat balance, and the surface temperature reaches its peak. After that, the surface releases more heat than it stores, which makes the surface temperature lower.

Summer will be a hot summer, not only the El Nino phenomenon will lead to climate warming, but also the carbon dioxide emitted by the frequent burning of human fossil fuels will lead to the melting of glaciers and the large specific heat capacity of water, which will lead to climate warming.
