Part 5 • Political instability
Concerns are mounting that altered weather patterns caused by global warming will stoke conflicts in various parts of the globe. No one argues that climate change alone will lead to war. But analysts suggest that it could be a pivotal factor that tips the balance vulnerable regions.

The worst effects of climate change may destabilize regions that were already shaky. The prime example: Bangladesh.
From Nepal to Nigeria, Indonesia to the Arctic Circle, a warmer world poses different problems.

Part 3 • Wildfires
October's disastrous wildfires in California - part of one of the most intense fire seasons in the United States in nearly 50 years - highlight the need to prepare for more fire risks. Solutions include building homes with fire-resistant roofs, windows, and landscaping, as well as rethinking how communities are laid out.

Part 4 • Sea-level rise
If projections for global warming are right, the world's oceans may rise nearly three feet by century's end. River deltas in places such as Egypt, Vietnam, and Bangladesh could be especially vulnerable. No country is working harder on finding answers than The Netherlands, half of which lies behind sea level already. Meanwhile, in the United States, efforts are under way in the Chesapeake Bay, New York City, and New Orleans to prepare for higher waters.
