Sea level rises and disappears a little island in the Bay of Bengal

February 2, 2010

( New Moore, an island of just 3.5 kilometers long by three wide, which was located in the Bay of Bengal, disappeared under the water product of sea level rise resulting from global warming, Prensa Latina reports from New Delhi , quoting the Indian Express newspaper.

The island no longer exists, said Sugata Hazra, director of the School of Oceanographic Studies of Jadavpur University. New Moore, protruding only two meters above sea level, now joins Lohachara, the first uninhabited island of the archipelago of Sunderbans who disappeared in 1996.According to scientific studies that upper house of Kolkata (formerly Calcutta), recent satellite images do not show traces of the island, which until its demise was the center of a territorial dispute between India and Bangladesh.

This is the first case in which nature solves a claim like this, and also demonstrates how weather can affect us all, beyond geographical boundaries, Hazra said.

He warned further that other rock formations located in the estuary formed by the mouths of the rivers Ganges, Brahmaputra and Meghna, are also in danger of being swallowed by the waters as a result of global warming.

The total area of islands in the Sunderbans, which runs between the Indian state of West Bengal and Bangladesh, 210 kilometers square has declined over the past 40 years, erosion has increased since 2001.

Countries at risk

According to the UN, ocean levels could rise three feet by 2100 due to accelerated melting of the poles and glaciers. Those most affected are the 43 countries of the Alliance of Small Island States (AOSIS) located in the Pacific Ocean, Mediterranean Sea, Indian Ocean and Caribbean Sea.

These nations already face serious problems of erosion, flooding, destruction of coral reefs, water scarcity and the high occurrence of hurricanes destructive potential.

The Southeast Asian countries will suffer from global warming than other parts of the world, according to a study by the Asian Development Bank (ADB). Since 2100, Indonesia, Philippines, Singapore, Thailand and Vietnam lost 2.2 percent annual gross domestic product (GDP), twice the world average.

A study published in early 2009 by the UN Program for Development (UNDP) said that Vietnam is one of the five countries most affected by climate change, especially global warming.

The sea level rise is one of the greatest dangers that afflict and Vietnam. If global temperature increases to two degrees Celsius and the sea rises one meter, will be flooded 90 percent of agricultural extension Mekong River Delta and a third of Vietnamese natural environment disappears.

Currently, more than two million hectares of agricultural land in the Mekong area were affected by salinity due to penetration of the sea to about 70 miles inland. Others 1.6 million hectares are degraded by erosion and reduced biodiversity.

Another example is Indonesia, the world’s largest archipelago, based on the so-called Pacific Ring of Fire. That nation tries to tell the islands that make up the country, estimated at about 17,480 so far, although the Indonesian authorities admitted that there may be two thousand less.

World Bank urges rich countries to assume their responsibility

The warming of the earth is becoming more complex challenge of development, taking into account that in one in four people living on less than $ 1.25 a day and that more than one billion people without have enough food to meet their basic food needs.

Developing countries assume the bulk of the costs of damage from climate change. Many of the inhabitants of developing countries live in physical exposure sites and poor economic conditions, and their adaptability is limited financial and institutional, concludes the World Development Report 2010 World Bank, Development and climate change.

"Latin America has emissions per capita, lower than the world average but experience high vulnerability to climate change impacts in the region. This is mainly due to the fact that the region contains great natural resources and ecosystems that are undergoing irreversible change. Therefore, adaptation actions to climate change assume a vital importance, "says Walter Vergara, chief engineer of the department of World Bank’s environmental development.

In the developing world there are 1,600 million people lack access to electricity. In these countries, whose average per capita emissions are a fraction of those in high income countries need to implement massive expansion in energy, transport, urban and agricultural production systems, the report says the international financial organization.

Developing countries can take the route of low carbon, while promoting the development and reduce poverty, but this depends on financial and technical assistance to high-income countries, says the Report Development and Climate Change.

The document recommends that high-income countries act quickly to reduce their carbon footprint and encourage the development of alternative energy sources to help solve the problem of climate change. The more advanced countries in the past produced most of the emissions of greenhouse gases, must act to support the future of mankind on the climate.

"The good news is that the possibility of achieving a world with a focus on intelligent climate is within our reach if we work together now to overcome inertia, reduce costs and change our energy systems, food and risk management for the purpose of ensure a safer future for all, "says Marianne Fay, co-director of World Development Report and Chief Economist of World Bank Sustainable Development.

If developed countries act now, it is feasible to achieve a world "with a smart climate approach" and the cost involved would be high but manageable. The key to this is to encourage funding activities in developing countries, where occur most of the increase in emissions in the future, says WB report.

In addition, countries must act together because no nation can take in isolation the interconnected challenges presented by climate change, and require global cooperation to improve energy efficiency and develop new technologies.

The report details that best practices and current technologies of low carbon could reduce energy consumption significantly, thus producing a saving of money. For example, you can cut energy consumption in industry and the energy sector between 20% and 30%, thereby helping to reduce carbon footprint without sacrificing growth.

Also, many of the changes aimed at reducing emissions of greenhouse gases also generate significant benefits in environmental sustainability, public health, energy security and financial savings. For example, by avoiding deforestation preserving watersheds and protecting biodiversity, in addition to which forests can be effectively used as carbon sinks.

To solve the climate problem requires a transformation of energy systems of the world in coming decades. Requires investments in research and development in order from 100 thousand to 700 billion year, a huge increase from the modest figure of 13 billion annual public funds and 40 billion to 60 billion annually in private funds currently spent.

On 26 March, World Bank experts and Marianne Fay Walter Vergara presented to the public paceño the World Development Report 2010.
