Rising levels in parts of the Indian Ocean may worsen monsoon flooding in India and Bangladesh.
According to a study led by Weiqing Han, the associate professor in atmospheric and oceanic sciences at the University of Colorado, Boulder, US, this is attributed to warming caused by manmade increases of greenhouse gases. The parts affected by the rising sea levels are the Bay of Bengal, the Arabian Sea, Sri Lanka, reports Nature Geoscience. |

Climate change is hitting coastal areas hard: rises in sea levels, ocean acidification, extreme events, bleaching and death of coral are all climate impacts which will require adjustments socially and economically. This report provides practical guidance for coastal communities and industries to adapt to climate change.

Climate change in coastal regions has of late taken a very serious turn for the worse, with its consequences going beyond damage to the coast. |
Impact of Global Warming on Oceanic and Coastal Biota This presentation is from the " Post Conference Climate Change India 2008",22-23 April 2008,Le Meridien,Pune India. Conclusions: Climate Change Projections * Climate models suggest an increase in mean surface air temperatures over India. The warming is more dominant during winter seasons. * Models suggest fewer colder nights in future, as minimum temperatures are liketo to increase more. * Climate models also suggest an increase in precipitation and extreme precipitation events over India during summer monsoon season. This means more floods to come. * Extreme rainfall and winds associated with tropical cyclones arelikely to increase. |
Sacred Groves  There is enough evidence that the human-induced climate change will drastically affect domesticated as well as natural biodiversity. The ecosystem people (forest dwellers, fishermen, farmers, pastoralists, mountain dwellers) living in regions such as deserts, semi-arid, coastal, mountain, forest will bear the maximum brunt of the climate change, and that their livelihood security (including food & water) will be adversely affected.It is also abundantly clear that the life styles followed by rich developed countries and the rich persons among the developing countries are solely responsible for the climate change.

Climate Change and the Coastal Region
The most alarming danger that besets the coastal regions is that a rise global temperatures will bring a rise in sea levels, with adverse impact. The observed trends in the mean sea level along the Indian coast indicate a rising of about one centimetre per decade, which is close to that in other parts of the globe. The projected future sea level rise could inundate low-lying areas, coastal marshes and wetlands, erode beaches and increase flooding and ssalinity of bays, aquifers and rivers |
Mangroves: The Trees on Prop Roots Prop up the Coastal Ecology
salt water forests, known as mangroves, can move from sea on the land and are well adapted to live under both the environmental conditions. These hold important clues to some of the evolutionary scientists who believe that the beginnings oflife forms tookplace in the coastal regions. In present times, the mangroves, wherever they exist, are considered very crucial to the livelihood as well as the ecology of the coast. |
Impact on River Deltas and Other Coastal
While global warming is a matter of worldwide concern, among the most vulnerable areas are the coastlines of less developed tropical countries such as, India. The river deltas, in particular, are already facing the brunt of climate change and these adverse impacts can be expected to increase dramatically in the course of this century. |
Refugees join list of climate-change issues
 Sea levels have risen so much that during the annual king tide season residents of Carteret Islands stash their possessions in fishing nets strung between the palm trees. For the first time in history, you could actually lose countries off the face of the globe. Climate change is a development issue that has some security aspects. With their boundless vistas of turquoise water framed by swaying coconut palms, the Carteret Islands northeast of the Papua New Guinea mainland might seem the idyllic spot to be a castaway. |
Prelude to the apocalypse Global warming poses the threat of submergence to the biodiverse Sunderbans in the future, which isn’t far away. Greenpeace India’s Peter Caton unveils the grim reality. For long, the Sunderbans was the world’s largest single block of tidal mangrove. Its freshwater swamp forest at the mouth of the Ganga, spreading across East and West Bengal, is known for the tiger, various species of birds, spotted deer, crocodiles and snakes. And, of course, the people.These days, the seasonally flooded Sunderbans faces death from rising water levels owing to global warming. If the average temperaturerises by another two degrees these islands could disappear under seawater.Initially, the Sunderbans — now intersected by a network of tidal waves, mudflats and small islands of mangrove — was a large single landmass. |
