WARMING TEMPERATURES MELT GLACIAL ICE

GLOBAL WARMING: 1,600 YEARS OF
ICE IN ANDES MELTED IN 25 YEARS
www.nytimes.com - Glacial ice in the Peruvian Andes that took at least 1,600 years to form has melted in just 25 years, scientists reported Thursday, the latest indication that the recent spike in global temperatures has thrown the natural world out of balance. The evidence comes from a remarkable find at the margins of the Quelccaya ice cap in Peru, the world’s largest tropical ice sheet. Rapid melting there in the modern era is uncovering plants that were locked in a deep freeze when the glacier advanced many thousands of years ago. 
Dating of those plants, using a radioactive form of carbon in the plant tissues that decays at a known rate, has given scientists an unusually precise method of determining the history of the ice sheet’s margins. Lonnie G. Thompson, the Ohio State University glaciologist whose team has worked intermittently on the Quelccaya ice cap for decades, reported the findings in a paper released by the journal Science.

The paper includes a long-awaited analysis of chemical tracers in ice cylinders the team recovered by drilling deep into Quelccaya, a record that will aid scientists worldwide in reconstructing past climatic variations. The weather presumably contributed to the food shortages that exacerbated that upheaval. Of greater immediate interest, Dr. Thompson and his team have expanded on previous research involving long-dead plants emerging from the melting ice at the edge of Quelccaya, a huge, flat ice cap sitting on a volcanic plain 18,000 feet above sea level. 
In the new research, a thousand feet of additional melting has exposed plants that laboratory analysis shows to be about 6,300 years old. "Ice that accumulated over approximately 1,600 years melted back in no more than 25 years," Dr. Thompson said.

Glacial ice that took 1,600 years to form in the Peruvian Andes took only 25 years to disappear due to earth’s increasingly warmer temperatures. The ice in South America has melted drastically leaving behind a large pool of water framed by exposed rock and diminished beds of ice. As the ice melts, plants that were trapped within it are exposed, and it is these materials that are being used to analyze the glacial area’s history. While greenhouse gas emissions from human sources of pollution, such as coal and gas, are reaching new peaks, the Vedic solution to environmental pollution is to change our consciousness from the selfish exploitation to protection and service to others.

WHAT DO THE VEDIC TEACHINGS TELL US? 
We create so many things but what we are doing to the environment? That’s one of the biggest conflicts in the world today. ... The oceans are becoming polluted. Over the years there is big oil ship just leak and the oil fell on ocean and millions of fish die and pollute so much of waters. Lakes are polluted. ... Now the ozone and the global warming it is an international problem. If we do not give up this type of polluting of the atmosphere this global warming is going to cause the solar ice caps to melt ... The pollutions are not created by simple people who are farming by natural ways. It is due to industries, chemicals. ... But if they are not in harmony with nature and harmony with God, they may create a nice thing now but destruction in the future.
