Why is the weather changing so much now?

Due to the industrialization of the world, factories emit a lot of greenhouse gases such as carbon dioxide, which will make it difficult for the sun to radiate the heat on the earth, thus global warming. When the world warms, the ocean can evaporate more water vapor, which will change cold and warm fronts, so the weather becomes more and more strange. Sometimes El Nino phenomenon occurs, which makes some areas of the earth warmer than in previous years, while others are colder than in previous years.
