Surviving in a warmer world, Part 6: The worst effects of climate change may destabilize regions that were already shaky. The prime example: Bangladesh.

Dhubri, India - To this day, nearly a quarter-century after he left, Loknath Das is afraid to return to the village where he was born.

The reason he gives is one heard throughout this corner of India, where Himalayan peaks give way to fertile flood plains: Immigrants from Bangladesh are taking over.

It is a visceral fear in India's Northeast, where people say they feel under siege - their culture, politics, and security threatened by a tide of Bangladeshis who are here illegally. "On the surface there is peace," says Mr. Das, who says he was forced out of his village through intimidation and murders by immigrants. "But this migration is a tragedy for us."

For now, there is relative calm. But security analysts worry that unrest could flare up again because of a new threat: global warming. As negotiators gather in Bali, Indonesia, this week to begin work on an agreement to fight climate change worldwide, concern is mounting that altered weather patterns will stoke conflict in various parts of the globe.

And this area of South Asia sits atop most experts' watch lists.

Bangladesh is not only one of the countries most vulnerable to climate change, it is also chronically unstable. It is in the midst of a political crisis and showing signs of nascent Islamist fundamentalism. The effects of global warming could amplify the forces of instability, experts say.

That remains an extreme view. The clearest threat, most agree, is a mass migration that sparks renewed conflict in the Indian Northeast - an independent -minded area of mountains and jungles fiercely proud of its distinct heritage and already fretted by a dozen insurgencies.

"It is the No. 1 conflict zone for climate change," says Peter Schwartz, chairman of the Monitor Group, a research firm in San Francisco that recently released a study on the security risks presented by climate change.

That field of study is relatively new, but analysts are beginning to lay the map of forecasted climate change over the map of political weakness to see where changes in weather could lead to volatility. No one argues that climate change alone will lead to war. But analysts suggest that it could be a pivotal factor that tips vulnerable regions toward conflicts.

"Climate change is a threat multiplier," says Geoff Dabelko, director of the Environmental Change and Security Program at the Woodrow Wilson Institute in Washington. "It's not that it creates a whole new set of problems, it's that it will make things that are already a problem worse."

For that reason, few expect climate change to throw Europe or North America into chaos. Both have the political stability and economic resources to cope. Areas that lack these advantages - such as sub-Saharan Africa, Latin America, and South Asia - are most at risk, experts say.

History suggests that climate can help breed political instability. One recent study charted climate changes, wars, and several other variables back to the 1400s. It found that significantly cooler periods were characterized by large-scale crop loss, starvation, and conflict.


More stress for a stressed nation

That would be an unwelcome development for a country frequently under duress. In its 36 years of independence, Bangladesh has had 14 governments - four of which were replaced by military coups. The current government is again under military stewardship, with civilian leaders being rounded up on corruption charges.
