Why is there a weather change?

The understanding of the process, severity and impact of climate change on different regions is still deepening, and scientists have confirmed the following points: 6? 1 carbon dioxide and other gases have formed a greenhouse effect in the atmosphere, preventing heat from reflecting back into space and increasing the temperature of the earth? 6? Will burning fossil fuels (such as coal and oil) release more carbon dioxide into the atmosphere? 6? 1 although carbon dioxide is not the strongest greenhouse gas, the content of carbon dioxide produced by human activities has greatly increased, which has become the culprit in enhancing the greenhouse effect? 6? 1 has reached the highest level in 650,000 years? 6? 1 90 can be regarded as the hottest decade in history, and 1998 is one of the hottest years. The following points have also been widely recognized: 6? 1 due to the emission of greenhouse gases such as carbon dioxide, it seems inevitable that the global average temperature will rise 1.3 degrees Celsius compared with that before the industrial revolution. Limiting the increase to 2 degrees Celsius is the only way to prevent climate change from causing more serious disasters? 6? 1 If greenhouse gas emissions are not controlled, the speed of climate change will be the fastest in human history? 6? 1 The climate feedback mechanism is likely to bring about a drastic and irreversible chain reaction, and no one knows to what extent climate change will lead to the "end of the world".
