POPSSacred river endangered by global warming:GANGES RIVER Quoted;"While India is one of the world's top producers of greenhouse gas emissions -- along with the United States, China, Russia and Japan -- it argues that the United States and other developed countries should reduce their own emissions before expecting developing nations to follow suit. Environmentalists say that kind of thinking is shortsighted and that India desperately needs strong laws in place at a time when the country is growing so quickly."

POPSThe Impending Himalayan Outburst
For more than a decade, the fear that the Himalayan glaciers may be melting have attracted the attention of geologists and policymakers. During this time, conferences and papers have been written about the topic and media coverage has also increased on this issue. And finally, here comes the most comprehensive study on the topic-- Impact of Climate Change on Himalayan Glaciers and Glacial Lakes: Case Studies on GLOF and Associated Hazards in Nepal and Bhutan. This 119-page scientific study focuses on the impact of warming temperatures on glaciers and glacial lakes in the Himalayan region. It warns of impending glacial lake outburst floods (GLOFs) – when rising waters from glacial melt breach dams in glacial lakes – and calls for early warning and mitigation measures to avert disaster. The document, released on June 5 in Kathmandu and Bangkok on the World Environment Day, is jointly produced by the International Centre for Integrated Mountain Development (ICIMOD) with the United N

POPSTethyan Himalaya : Eduardo Garzanti A complex interplay of tectonic, eustatic and oceanographic processes concurred in the development of ‘drowning unconformities’ at the top of the Giumal clastic shelf. Rapid deepening and waning of both volcanic and quartzo-feldspathic terrigenous detritus are mainly ascribed to the global mid-Cretaceous sea-level rise and to rapid thermo-tectonic subsidence at the end of the short-lived Albian magmatic event, possibly related to a mantle plume rising beneath northern India. Intensification of the east-bound oceanic current off the north margin of India after the final break-up of Gondwanaland was responsible for continuous resuspension and minimal accumulation rates around the shelf-break. The associated coastal upwelling favoured impingement of the oxygen-minimum zone on the outer shelf, with glauco-phosphorite deposition coinciding in time with peak global transgressions and ‘anoxic events’ in the world oceans.

POPSHimalayas: Two continents collide About 225 million years ago, India was a large island still situated off the Australian coast, and a vast ocean (called Tethys Sea) separated India from the Asian continent. When Pangaea broke apart about 200 million years ago, India began to forge northward. By studying the history -- and ultimately the closing-- of the Tethys, scientists have reconstructed India's northward journey. About 80 million years ago, India was located roughly 6,400 km south of the Asian continent, moving northward at a rate of about 9 m a century. When India rammed into Asia about 40 to 50 million years ago, its northward advance slowed by about half. The collision and associated decrease in the rate of plate movement are interpreted to mark the beginning of the rapid uplift of the Himalayas. Fifty kilometers north of Lhasa (the capital of Tibet), scientists found layers of pink sandstone containing grains of magnetic minerals (magnetite) that have recorded the pattern of the Earth's flip-flopping magnet

POPSWadia Institute Himalayan Geology The Wadia Institute of Himalayan Geology carries out basic research in Himalayan Geology and related fields which includes geodynamic evolution, mountain building processes, geoenvironment and mineral resources. The research activities of the Institute are conducted through time - bound project mode and the areas of its multi- disciplinary research are organised into the following four areas namely: * Tectonophysics. * Petrology & Geochemistry. * Lithogenesis- Biostratigraphy. * Earth Resources and Environment.

POPSfossilised jawbone of the oldest whale yet discovered The ocean it once inhabited was destroyed when the Indian continent collided with Asia, creating the Himalayan mountains. This, they believe, shows that the first whales swam in rivers, estuaries and oceans in search of fish, as well as spending time on land. Modern whales have become entirely adapted to ocean life, but have retained the need to breathe. Monday, December 21, 1998 Published at 23:51 GMT Sci/Tech Oldest whale fossil confirms amphibious origins Whales once lived on land, only dipping into the ocean for food The fossilised jawbone of the oldest whale yet discovered has confirmed the theory that the giant sea mammals' ancestors were amphibians. They rested and reproduced on land but dived into rivers and the ocean to fish for food. The jawbone, complete with teeth, is 53.5m years old - 3.5m years older than previous record holder - and was found in the Simla Hills of northern India.

POPSMystery of the Himalayas solved Scientists can't even be sure how high the land was before India crashed into Asia, obliterating the Tethys Ocean which used to separate them. Like western South America, the coast could have been lined by mountains.Some scientists have even suggested that the rise of the Himalayas could have triggered the Ice Age by increasing the total amount of global rain and removing vast amounts of carbon dioxide from the air.By pushing the Himalayas to their current altitude, more than 8,000m above sea level, and raising the Tibetan plateau to 5,000m, the detachment of the block was responsible for both the monsoon rains that make south Asia so fertile and the Gobi desert in central Asia. Warm winds blowing from the Pacific Ocean cool as they rise over the mountains, releasing the moisture they contain as torrential rains, leaving almost no water to fall on the arid interior of the continent.

POPSHimalaya climate change expedition Later we found out some American tourists had held a "Free Tibet" banner. A serious offence in China. We didn't need this, for our work will involve banners too. Later the clouds lifted and Everest stood proud against the deep blue sky in the late afternoon light. I felt humbled and elated at the same time. Here I am looking at the highest point in the world.
