The "Thames Barrier" was opened with much fanfare and a promise to keep London safe from the surging sea. But the gates are closing twice as often as was originally intended, and it's now clear they won't be enough to keep the water out. We look at the plans to keep London dry.

Disappearing towns

There are a variety of ways to try and hold back the water, but an important part of adapting to a warmer climate will be knowing when it's just not worth the flight. We visit Happisburgh, on the British coast, where the government has decided there's nothing it can do to stop the town from sliding into the North Sea. Residents, not surprisingly, don't agree.

Nobody has to tell the residents of the Maldives that it's time to act. They've already abandoned one of the islands in their low-lying chain, and are building a rectangular artificial island called Hulhumale to give the Maldivian capital room to expand onto higher ground.

Nomads no more

Video: David McGuffin reports (Runs: 3:50)

The Turkana in Northern Kenya have been nomadic cattle herders since the beginning of time according to their legends, but now some communities of Turkana are turning to farming due to the increasing cycle of drought that has devastated their cattle herds. With help of aid agencies, they are now growing drought-resistant crops like sorghum and developing better water management methods to preserve the rains when they come.

Using state of the art computer graphics and surround screens, a group from the University of British Columbia is set to begin showing residents of low-lying Delta, B.C., what their community could potentially look like in 2100.

Pine beetles

The changing climate brought a "red tide" to Prince George, and now this city in the forest is on the front lines of adapting to a warmer world. After watching their lumber livelihood destroyed by the pine beetle, residents are looking at ways to adapt and survive. The rest of Canada looks to Prince George for answers, because the beetles are on the move.

Hot cities

Video: Maureen Taylor reports (Runs: 6:26)

In 2003, a heat wave in Europe killed 35,000 people. As summer temperatures rise, public health and safety authorities are being forced to adapt. The effects of global warming are magnified in cities because of the population density, air flow and microclimates. Some U.S. cities have already learned some difficult lessons and are making changes now to save lives in the future.

Sinking Alexandria

Alexandria, Egypt, is one of the great cities of the ancient world, a cultural centre and home of wonders. But now it is dealing with a changing climate and must find ways to adapt.

Salty farmers

A problem in many parts of the developing world is the steady encroachment of salt water into farming lands. In Bangladesh, they're adapting by raising shrimp instead of growing crops. How are the farmers in the Nile delta adapting to an aggressive Mediterranean Sea?

Reclaiming desert

Climate change and rising temperatures can lead to drought and the loss of farmland to the desert. The world is looking to Israel, renowned experts at reclaiming the desert, for help in stopping the sands from spreading.

The land famous for building dikes and reclaiming land has also faced devastating and deadly floods. The National looks to the past to see what Holland may be facing in the future.

Holland prepares for the future

How is Holland going to live with even more water? The National visits a community designed to cope with persistent flooding, looks at buildings that are being built in the middle of the sea, and explores towns that have been designated to "disappear" as Holland looks for places to put its rising waters.

Farmers in Peru

Video: Kelley Crowe reports (Runs 10:56)

Climate change is melting glaciers in the Andes, and there isn't as much rain in the high plateaus. A one-of-a-kind ecosystem in Peru is in danger of disappearing.
