The World Meteorological Organization’s State of the Climate in Asia 2024 report warns that the region is warming nearly twice as fast as the global average, driving more extreme weather and posing serious threats to lives, ecosystems, and economies. In 2024, Asia experienced its warmest or second warmest year on …
India's Tsunami Early-Warning System in the Indian Ocean is close to completion, but authorities are clueless about how to circulate alerts. An interim system has been in place since July 2005 and the new information network got commissioned in October 2005. The National Disaster Management (ndm), which looks after the …
On December 13, 2006, scientists warned that the Arctic ice is melting at a rate faster than was estimated. The ice has been shrinking steadily over the past 30 years, but now scientists say there's a possibility of an ice-free Arctic in the next few decades. Bruno Tremblay, assistant professor …
Monthly and 3-hourly precipitation data from twentieth-century climate simulations by the newest generation of 18 coupled climate system models are analyzed and compared with available observations. The characteristics examined include the mean spatial patterns, intraseasonal-to-interannual and ENSO-related variability, convective versus stratiform precipitation ratio, precipitation frequency and intensity for different precipitation …
technology cannot always substitute sound preparedness on the ground; Indonesia learnt it the hard way when a tsunami triggered by an earthquake off the island of Java killed hundreds of people last month. An interim tsunami warning system declared operational in the Indian Ocean region barely a month ago did …
May 10, 2006, was a special day for the exiles from the Chagos group of islands in the Indian Ocean. On that day, uk's High Court ruled that they be allowed to return home. In the late 1960s, all indigenous Chagossians were evicted to make way for a us air …
a recent study at the Scripps Institution of Oceanography, usa , claims that the combined effect of air pollution (aerosols/particulate matter) and greenhouse gases may induce greater variability in the Indian monsoon
The uk High Court recently ruled in favour of a group of Indian Ocean islanders who were forcibly removed to make way for a us airbase decades ago. The Ilois or Chagossians are inhabitants of Diego Garcia, the largest island of the Chagos Archipelago in the Indian Ocean, which is …
Located in the Indian Ocean, the Great Nicobar Island is home to the little-known tribe of Shompens. Displaying a stark resemblance to African populations with some Mongoloid traits, they still cling to the life of hunter-gatherers. Except occasional visits by researchers and government officials, the enigmatic Shompens, who number just …
Sea level changes can be of two types: (i) changes in the mean sea level and (ii) changes in the extreme sea level. The former is a global phenomenon while the latter is a regional phenomenon. Estimates of mean sea level rise made from past tide gauge data at selected …
• A group of 60 on horsebacks who call themselves The Nomads have undertaken a tour of the world to promote organic farming and complete respect for the environment. • Every Time I See the Sea: Life After the Tsunami , an interactive exhibition of photographs and footage from India …
• A new reality television series is teaching Britain's "most wasteful families' how to live simpler, greener lives. Each week, the BBC's, No waste like home looks over a different family's house. It then suggests techniques for cutting down on their ecological footprints. Despite early rave reviews from within the …
The southwest monsoon current in the form of a crossequatorial low level jetstream (LLJ) with its core at an altitude of about 1.5 km and core wind speeds of 80
Tropical cyclones—variously defined as hurricanes, typhoons, and cyclones—regularly impact human populations and periodically produce devastating weather-related natural disasters. The epidemiology of tropical cyclones is fundamentally determined by the physical forces of massive cyclonic systems intersecting with patterns of human behavior. The destructive forces of cyclonic winds, inundating rains, and storm …
South Asian emissions of fossil fuel SO2 and black carbon increased 6-fold since 1930, resulting in large atmospheric concentrations of black carbon and other aerosols. This period also witnessed strong negative trends of surface solar radiation, surface evaporation, and summer monsoon rainfall. These changes over India were accompanied by an …

At 6.29 am, on the morning of December 26, 2004 an undersea earthquake erupts in Sumatra, triggering off tidal waves called tsunami. A minute later, the India Meteorological Department (imd) gets the news. In 15 minutes, imd tracks the tsunami to the Indonesian coastline. But they make no attempt to …
The monitoring and management of the Indian coastline has come under sharp focus after the tsunami disaster. There is now a strong demand to implement the Coastal Regulatory Zone (crz) notification of 1991. Let us look at why protecting coastal ecology is so critical. Natural protectors, such as sand dunes …
The Indian ocean covers 73,556,000 sq km, or 20 per cent of the world’s surface. Aspects like oceanography, geophysical phenomena, undersea exploration and economic and military uses have a bearing on ocean behaviour. How cognisant are our experts with this large water body? Other than isolated research programmes associated with …
It would be naive to assume that disasters will stop. We cannot change the nature of disasters. What we can change, certainly control, is the scale that a disaster wreaks. This is precisely what disaster preparedness
Scientists believe that the Sumatra earthquake made the earth wobble on its axis and permanently accelerated the Earth's rotation, shortening a day by a fraction of second and permanently altering the regional map. The devastating undersea earthquake off Sumatra in Indonesia has brought about some striking changes in the Indian …
