Very cold, government limitations and environmental hazards
The atmosphere plays an important role in modulating the precipitation and also in the radiative forcing at the land surface, through the radiative effects of clouds, trace gases including carbon dioxide, water vapour and aerosols. ... Clouds are the prime regulator of the energy exchanges in the atmosphere.
Answer:
50-64
Explanation:
China is the nation with the largest population in the world, and that has been the case throughout all of the written history, and probably even before that. The country had very large birthrates, which was leading to rapid growth to the population. Because of that, there was even a law that restricted the families as to how many children they can have. Because of that law, the population of China started to gradually age, so the percentage of the younger age groups has been declining, while the percentage of the older age groups has been on the rise. This has led to the age group of 50-64 to account for 120 million people in China, a percentage that has grown almost twice compared to several decades prior to that.
