This paper focuses on the past three-decade period. By using multi-source satellite data, field monitoring data, and data from authoritative databases, it deeply explores the correlation between global ocean heat content and meteorological trends. The study finds that from 1955 to 2023, the global ocean heat content from 0–2000 meters has significantly increased, especially from 2014 to 2023, reaching a peak in 2023. In terms of stratification, the warming rate from 0–2000 meters is 0.9 ± 0.1 W/m², and there is an increase below 2000 meters but with uncertainties. Meteorologically, the concentration of greenhouse gases has increased, the sea surface temperature has risen, and the frequency of floods and extreme temperature disasters has increased in the past 30 years. The number of deaths from flood disasters has decreased, and the economic losses from storm disasters have increased. The ocean heat content is positively correlated with the sea surface temperature and the concentration of greenhouse gases, and it also exacerbates disasters such as tropical storms, hurricanes, and marine heatwaves, threatening the coastal ecology and economy. This research provides a key basis for understanding the mechanism of climate change.
