Applying paleoclimatic reconstruction of greenhouse gases and correlation analysis of global and Yangtze Estuary SST changes with industrial revolution

This study explores the differences of different proxies in paleoclimatological reconstruction. It was found that N2O content increased first and then decreased after the first industrial revolution, while CO2 and CH4 content increased. After the Second Industrial Revolution, the three kinds of greenhouse gases all increased sharply, and the amplitude was relatively consistent. The analysis shows that the annual variation of the Changjiang Estuary is larger than that of the whole world, showing a canine shape. Compared with other historical thermal events, it is found that global change is directly related to the Industrial Revolution.
