Why is the weather warmer this year than in previous years? It's not still the greenhouse effect, is it?

First, the temperature of our earth will go through a process of gradual increase and decrease, which is also called "ice age" and "interglacial age". The ice age is the process of climate cooling, and the interglacial period is the process of climate warming. The earth is now in the interglacial period of warming.

Second, global warming, of course, the most important reason is the above. In addition, it is because humans burn a lot of fossil fuels and release too much carbon dioxide gas. Moreover, due to man-made deforestation, the ability of forests to absorb carbon dioxide becomes worse, which leads to the gradual intensification of the greenhouse effect and the warming of the climate.

Third, of course, the possibility of sudden climate change is not ruled out. For example, because of "El Nino phenomenon" or "La Nina phenomenon", as previously reported, the rainfall in the first eight months of Macau 1997 exceeded the average annual rainfall in the past 40 years; The rainfall in Hong Kong has also broken the historical rainfall record. On the day of Hong Kong's return to China on July 1, continuous heavy rain was accompanied by a grand handover ceremony, which was impressive. Generally speaking, under the influence of El Nino, the winter temperature in most parts of the country is higher than normal, and the phenomenon of waterlogging in the south and drought in the north is more obvious.

These are my own immature views. If there are any shortcomings, please criticize and correct me.
