When will the weather get warmer?

In the middle and late March, the temperature began to rise in ............. Because the earth receives a certain amount of solar radiation every day, after receiving solar radiation on the ground, some energy will return to the universe in the form of ground reverse radiation. After the industrial revolution, a lot of fossil fuels were used on the earth, and a lot of greenhouse gases such as carbon dioxide were discharged into the atmosphere. The energy radiated from the ground was absorbed by these gases, which led to the warming of the atmosphere and the warming of the earth, which is the greenhouse effect!
