Experts suggest that the oceans undergo periodic warming and cooling, with the Pacific Ocean fluctuating every decade. Currently, the world may have entered a 30-year global cooling period, with temperatures declining year by year. Skeptics of global warming claim that global temperatures will not return to the 1998 peak until at least 2030.
Now, global warming has been listed as the most critical international political issue. Countries seem to believe that global warming is threatening the survival of human civilization, but is this truly the case? In reality, over the past 11 years, the warmest year was not 2008 or 2007, but 1998. Global temperatures have not risen at all.
According to a BBC report, despite the continuous increase in carbon dioxide emissions, experts have failed to predict the rise in global temperatures. Climate change skeptics have long maintained that humanity's impact on climate has been exaggerated. They argue that global warming is the result of natural cycles that determine the Earth's temperature, which are beyond human control.
Research published in November last year by Professor Don Easterbrook of Western Washington University indicates a close relationship between ocean and Earth temperatures. He states that the oceans undergo periodic warming and cooling, with the most significant cycle being the "Pacific Decadal Oscillation."
Hong Kong's Ta Kung Pao points out that the 1980s and most of the 1990s were an active period for the Pacific Decadal Oscillation, meaning temperatures during this time were higher than average. Various observations also show that Earth's temperature rose during this period.
However, over the past few years, temperatures have declined, and recently, it has begun to cool. Such cycles have historically lasted nearly 30 years. Could global temperatures follow the same pattern? The global cooling from 1945 to 1977 coincided precisely with a cooling cycle in the Pacific. Easterbrook says, "This practically guarantees us about 30 years of global cooling in the future."
Last month, Mojib Latif, a member of the Intergovernmental Panel on Climate Change (IPCC), also stated that we may have entered a period of global cooling, which could last another 10 to 20 years. Professor Latif is a researcher at the Leibniz Institute of Marine Sciences at Kiel University in Germany and one of the world's foremost experts on climate modeling.
Skeptics of global warming argue that global temperatures will not return to 1998 levels until at least 2030. They claim that, influenced by oceanic and solar cycles, we are more likely to experience a period of global cooling.
