Global Warming A Scientific Introduction – Part 3

We looked at the climate changes caused by the sea and ice in the region. People who live in coastal areas know very well about the majesty and influence of the sea. Humans living in other land-based areas are familiar with rivers and lakes. For thousands of years, rivers and lakes have been the backbone of human activities such as drinking water, irrigation and industries. What changes have occurred in rivers due to global warming?

In, when I came to Tamil Nadu, I went to Poombukar. There, I thought I would be able to see the Cauvery flowing in great flood before it merges into the sea. A few miles before reaching the sea we see the Kaveri. This is the fate of many rivers in the world today, not just Cauvery. The Colorado River, America's largest river, has an 80 km stretch before joining the ocean. Disappeared before. Peruvian rivers such as India's Ganges, Brazil's Amazon and Canada's St. Lawrence are not far before reaching the ocean. Also, one of the biggest Indian issues today is cleaning the Ganges. Two major problems for the Ganga River. The first problem is that Email Data the water coming down from the glacier is decreasing. The second problem is that everywhere, factories and wastes are mixed in the river. This type of problem, in North America in the 1970s, Mostly fixed. But developing countries still struggle to prevent river water pollution from factories.

In this article, I will try to describe several things, focusing on the Colorado River in the United States. This applies to Godavari, Cauvery and Ganges. This is because there is more material on impact and conservation measures on the Colorado River and the Ganges River. What is said in this article is applicable to all major/small rivers.

Pollution control is an issue – what does this have to do with global warming, one might ask. Pollution control is the first step. Second thing we need to look at is global warming impact and river conservation efforts. Without the first step, there is no second step. Assuming that a highly polluted river does not have a proper source of water – be it rainwater (Caveri), snowmelt (Ganges, Colorado), whatever, human activities on the river will soon cease to exist.
Colorado River, USA, 2,334 km. long Seven US states and two Mexican states lie in its path. 40 million Americans depend on the Colorado River for their lives. The Ganges River in India is 2,704 km long. Five Indian states and Bangladesh are on its way. 400 to 500 million people depend on the water of the river Ganges. Through both the rivers, snow rivers in the mountains. On both the rivers, dams have been constructed here and there. Both the Americans and the Indians take pride in controlling the two rivers. Only one thing can be said for sure. Today 's Colorado is tomorrow 's Ganges . _ So, what's going on in the Colorado River?



Scientists' top prediction is that states in the US Southeast are on track to surpass a 20-year drought and get even worse. Scientists say that the term famine is not correct . A drought lasts a year or two; Not more than 20 years. Rivers drying up is nothing new. What is the connection between global warming and drying up of rivers?

Nature , a river , for thousands of years , 2,000 km . m . – has been placed over 100,000,000 because of a very complex system behind it . We have used this system in many ways, starting with irrigation of fields and power generation. For the last 2,000 years we have been using such rivers as rivers of life. But, for the last 150 years. We know that big cities, factories, and industries developed along the banks of rivers use river water and also mix sewage with river water. Somehow, nature brought these wastes to the sea as a hindrance in the way. But that same urbanization, and industrialization, that came as the Earth began to warm up more and more, changed the source of the river. For the last 40 years, humans have been trumpeting to the world that they are not involved in this matter. True, it is not.

In the previous section, we saw that glaciers are melting. In this section, we will see how important the timing and amount of melting of these are.

After spring started, after a couple of months, the mountains began to snow. Today, due to global warming, snow melts before the end of winter
Farmers who rely on river irrigation can, to some extent, advance sowing. Even if the snow melts quickly in the mountains, if the heat is not enough for the crops in the plains, the water in the river is of no use.
