By Y.S. RANA,Kasauli- April 19 : Global warming is a natural process and man’s activities have no role to play in enhancing or reducing the cyclic process sounds incredible but it is true for Dr Ritesh Arya, a renowned geologist of Himachal Pradesh. He seeks to redefine the phenomenon as a natural cyclic process, holds Guinness record for his feat of drilling the highest bore well in the world, will be leaving for Lisbon, Portugal in July next to present his latest research paper on the subject at the “Global Conference on Global Warming.”His new concept of bio-geologic cycle may demolish the “myth” that global warming is man-made phenomenon and says it’s a “100 per cent natural cyclic process.” He termed the views propounded by the Nobel prize-winning Inter-Governmental Panel on climate change (IPCC) as an “unnecessary myth about global warming.”
Dr Arya is all set to introduce a new concept of bio-geologic cycle to explain the relevance of global warming in shaping the earth now and in the future. At present, he is busy in giving the final touch to his research paper to be presented at the conference. “My research contains actual field geological evidence collected in the cold desert of Ladakh region to show global warming is a 100 per cent natural cyclic process. We are now in a global warming era and it has been continuing since the last Ice-age, believed to have ended around 10,000 years ago,” says Dr Arya.He will be employing qualitative and quantitative distinctions in the deposition of sediments (now solidified as rock) to demonstrate the cyclical warming and cooling phases that the earth seems to have undergone over the time.
Dr Arya, who was listed among the top 10 small-scale renewable energy innovators at the World Future Energy Summit held at Abu Dhabi in January, 2011 for his work on geo-thermal energy in the Himalayas.
Stressing his point of research, he said that the IPCC stated global warming was man-made especially from uncontrolled carbon dioxide emissions. But the Indus Valley Civilization had been destroyed nearly 5000 years ago because of the melting of Indus glacier and when there were no sign of pollution or vehicular traffic, says Dr Arya.
While elaborating his research, he said that the centre of C-alphabet representing a global warming maxima and it was at this time where maximum mountain flash flooding leading to maximum destruction and erosion along the glacio-fluvial basin took place and led to a sea-leval rise and submerged of land near coastal areas.
“By knowing which part of the C-curve paleo signature we are in, we may predict if we are entering the global warming or cooling phase and when the next global warming maxima will come. But a lot depends on the accuracy of exact age of the last Ice-age, he stated. “Presently, we are in the half-cycle and it seems that we have entered into a warming phenomenon. The flash-flood and mud-slide in Leh and other parts of the world last year are indicators that we are either at the maxima of global warming or near it,” Arya said.
“The phenomenon should be put in right perspective as today almost every human activity right from vehicular emissions to use of polythene is being linked to global warming which was a much larger event that started as soon as the Ice Age ended. The fact was that the “biotic” agents (man and other living organisms) had a very small role compared to the “abiotic” (geological, geomorphologic, climatologic, planetary and hydrological) events like earthquakes, volcanic eruptions, tsunamis, movement of glaciers and landslides” he told
He said that the core material found during deep drilling at Khardung La (over 18,000 ft) was geologically similar to the one found on the banks of Indus river and that established a link between global warming and glacial movements. Disappearance of river Saraswati was a geological event caused by global warming.
