7 The reasons that affect climate change in a region for a long period of time or in a certain period are numerous and complex. People have not yet been able to explain the impact of various factors on climate change. However, it can be asserted that even if human society develops to this day, in general, Natural factors are still the dominant factors affecting climate. Human activities are still not enough to affect the basic attributes of regional climates, and even less to cause huge climate changes such as glacial or interglacial periods. The text mainly states:. ['The climate of a region is the result of a combination of factors.', 'The basic attributes of the regional climate depend mainly on natural factors.', 'Human activity is not enough to affect the climate of an area.', 'Human understanding and analysis of climate influences is not enough.']
