11.4 Droughts in India



1) Why are their water reserves depleted so much?  One abnormally hot year doesn't drain everything.  What is the real cause?
2) How can we help here in Barrie?
3) How is El Nino not helping the situation?  What is El Nino?  What is La Nina and how could it help?
4) How is this related to the global warming and climate change?

    It is found that India’s water is depleting so much not only because of the hot weather but because of their growing population. Groundwater levels are falling as India’s farmers, city residents and industries drain wells and aquifers. The Indus Basin aquifer of India and Pakistan, which is a source of fresh water for millions of people, is the second-most overstressed with no natural replenishment to offset usage, said two new studies led by the University of California - Irvine (UCI), using data from GRACE satellites. About a third of the Earth's largest groundwater basins are being rapidly depleted by human consumption, the studies said. It is difficult to stop the population growth in India because most people may not have access to birth control and other preventions but there are some things we can do to help their water issue. As I was researching I found many programs which people can donate to aide India’s water problem. I think that that is one of the best things we can do because we are directly funding money to these organizations. We could also create our own organizations to help this issue. The Indian monsoon -- which besides India also affects other regions of south and Southeast Asia and Australia -- is the most economically important because of its serious influence on the economy of India and neighboring countries. Because of El Niño, warm zones in the Pacific cause the warm air to rise and cause circulation cells. Such cells disrupt the monsoon circulation cell in the Indian Ocean, which would disrupt its formation, causing poor monsoon rains all over the subcontinent. This means that India does not get the rainfall that they plan for. According to Colombia University, El Niño is “a complex and naturally occurring weather pattern that results when ocean temperatures in the Pacific Ocean near the equator vary from the norm.” Even without El Niño, 2015 would have been a record warm year, but climate scientists believe El Niño was responsible for 8 percent to 10 percent of the warming. This relates to global warming because it just shows how due to greenhouse gases humans have put into the atmosphere; it is creating a larger impact on our world. Humans are responsible for 90% of this warming trend that happened this year.
