Which month does it start to get warmer?

March. The time when the weather begins to warm up is generally in March, that is, in February of the lunar calendar, before and after the fright. In addition, there is a traditional time point, that is, May 1969, which is also the time when the weather gets warmer. Global warming is a phenomenon related to nature, which is due to the continuous accumulation of greenhouse effect, resulting in the imbalance of energy absorbed and discharged by the geo-atmospheric system, and the continuous accumulation of energy in the geo-atmospheric system, leading to rising temperature and global warming. Because people burn fossil fuels, such as oil and coal. Or cutting down and burning down forests will produce a lot of carbon dioxide, that is, greenhouse gases, which have a strong permeability to visible light emitted by the sun, a strong absorption to long-wave radiation emitted by the earth, and a strong absorption of infrared radiation from the ground, leading to an increase in the temperature of the earth, that is, the greenhouse effect. Global warming will redistribute global precipitation, melt glaciers and frozen soil and raise sea level, which will not only endanger the balance of natural ecosystems, but also affect human health and even threaten human survival.
