Over the past 1,000 years, the magnitude of climate change in the Yangtze River Basin is smaller than that in the Yellow River Basin, and the rainfall recovery capacity is stronger than that in the North. Each time a severe cold strikes, the North suffers far more damage than the South, so China's economic center has moved from North to South. which of the following can best refute this statement? ['The natural environment is not a major factor in economic development.', 'Not the higher the latitude, the greater the magnitude of climate change.', 'The North does not experience severe winters every year.', 'Rainfall in the Yangtze River Basin is not always greater than in the Yellow River Basin.']
