Studies have shown that the global average temperature has not significantly increased over the past 15 years, which seems to contradict the general background of global warming caused by greenhouse gas emissions. However, temperature changes are caused by two parts, dynamic temperature, and radiant temperature, and their climate effects Research must consider both the interdecadal changes in the dynamic factors of the climate system, and quantify the role of radiant temperature caused by human activities. In fact, the dynamic temperature has shown a significant cooling trend in the past 15 years, and the radiant temperature has continued to rise. The offset has caused the stagnation of global temperature growth in recent years. Which of the following inferences is correct? ['Decadal changes in the dynamics of the climate system have "cooled" the atmospheric temperature.', 'Megatrends in global warming caused by increased power and radiation temperatures.', 'Air temperature stability depends on the same change in power temperature and radiation temperature.', 'Dynamic cooling of the climate did not significantly contribute to global warming 15 years ago.']
