World’s largest rivers drying up due to climate change

Wednesday, March 17th, 2010

About one-third of the world’s mightiest rivers including the Ganges, the Niger and the Colorado, have been drying up over the last 50 years due to change in climate.

This poses a threat with dangerous consequences for the most populous regions in West Africa, South Asia, China and the Western USA.

The city of Adelaide in Australia could run out of water within 2 years.

The number of people impacted by extreme weather events has doubled within 30 years and is likely to increase by a further 54% by 2015.

Lake Mead in Southwestern USA could dry up by 2021

Lake Mead

There is a 50% probability that Lake Mead, a major source of water for millions in Southwestern USA, will dry up by 2021. Human demand, natural forces such as evaporation, and human-induced climate change are creating a net deficit of nearly 1 million acre-feet of water per year from the Colorado River system that includes Lake Mead and Lake Powell. This amount of water can supply roughly 8 million people.

“We were stunned at the magnitude of the problem and how fast it was coming at us,” says marine research physicist and study coauthor Tim Barnett of the Scripps Institution of Oceanography of the University of California at San Diego. “Make no mistake, this water problem is not a scientific abstraction, but rather one that will impact each and every one of us that live in the Southwest.”

Cancer strikes animals due to environmental pollution, which may affect human health

Thursday, March 11th, 2010

In 1996, Dr. Frances Gulland, the director of veterinary science at the Marine Mammal Center in Sausalito, and colleagues at the University of California, Davis, found that a striking 18 percent of deaths in stranded adult sea lions were the result of tumors in the reproductive and urinary tracts. Scientists also found that about 18 percent of dead beluga whales stranded in Canada’s St. Lawrence River had intestinal tumors or other cancers that were linked to industrial pollutants. Fish in contaminated waters have tumors, but not those in clean water. Dogs that are exposed to herbicides from chemically treated lawns have more cancers than those that are not.

The plight of sea lions will affect humans, since they “eat a lot of the same things we do,” said Dr. Gulland.

One third of the population is threatened by desertification

Friday, March 5th, 2010

One third of the population is threatened by desertification caused by climate change. The United Nations (UN) Secretary-General Ban Ki-moon stated “we must reconsider our agricultural practices and how we manage our water resources, with agriculture and livestock raising accounting for 70% of fresh water use and up to 80% of deforestation.”

Water shortages could affect two thirds of the world’s population by 2025

Thursday, February 25th, 2010

The world’s demand for water increases 64 billion cubic meters annually  – equivalent to the entire consumption of Egypt. Population growth is the main reason, but climate change and water waste make things worse. Two thirds of the world’s population could be affected by water shortages in 2025, threatening the world’s security.

60-90% of Colorado River supply to be lost by 2050 due to global warming

Thursday, February 25th, 2010

Reduction could leave the Southwest short of 500 million cubic metres of water by 2025. There is a 50% probability of Lake Mead, the reservoir on the Colorado River, drying up in 20 years.

Indian agriculture threatened by large scale drought and water shortage

Thursday, February 25th, 2010

In summer 2009, Bhopol, India experienced the effects of drought with a late monsoon and the driest June in 83 years, creating conflict situations between neighbours.

The farming economy was in crisis due to lack of rain in northern areas and low levels of water in lakes. Upper Lake, the largest man-made lake in India, with a 1,000 year history was reduced from 38 sq km to 5 sq km.

Up to 4 billion people will be affected by water shortages by 2050, says UN.

Beijing to run out of water by 2030; 16 Philippine rivers and lakes already dry

Thursday, February 25th, 2010

One out of five people in Asia do not have access to safe drinking water. Climate change will increase frequency of droughts and floods. Beijing will have used up all their available water supplies by 2030. China has 7% of the planet’s water resources, yet they need to supply one fifth of the global population. 16 Philippine rivers and lakes are already dead during summer and only 33% are suitable as a water source.
