Elsewhere in Asia even more astonishing actions are being taken. Chewang Nophel lives in a mountainous region in India, where he is known as the Ice Man. The loss of glaciers(冰川) there due to global warming represents an enormous threat to agriculture. Without the glaciers, water will arrive in the rivers at times when it can damage crops. Norphel’s inspiration came from seeing the waste of water over winter, when it was not needed. He directed the wasted water into shallow basins where it froze, and was stored until the spring. His fields of ice supply perfectly timed irrigation(灌溉) water. Having created nine such ice reserves, Norphel calculates that he has stored about 200, 000m3 of water. Climate change is a continuing process, so Norphel’s ice reserves will not last forever. Warming will overtake them. But he is providing a few years during which the farmers will, perhaps, be able to find other means of adapting.
Increasing Earth’s reflectiveness can cool the planet. In southern Spain the sudden increase of greenhouses (which reflect light back to space) has changed the warming trend locally, and actually cooled the region. While Spain as a whole is heating up quickly, temperatures near the greenhouses have decreased. This example should act as an inspiration for all cities. By painting buildings white, cities may slow down the warming process.
In Peru, local farmers around a mountain with a glacier that has already fallen victim to climate change have begun painting the entire mountain peak white in the hope that the added reflectiveness will restore the life-giving ice. The outcome is still far from clear. But the World Bank has included the project on its of "100 ideas to save the planet”.
More ordinary forms of adaptation are happening everywhere. A friend of mine owns an area of land in western Victoria. Over five generations the land has been too wet for cropping. But during the past decade declining rainfall has allowed him to plant highly profitable crops. Farmers in many countries are also adapting like this—either by growing new produce, or by growing the same things differently. This is common sense. But some suggestions for adapting are not. When the polluting industries argue that we’ve lost the battle to control carbon pollution and have no choice but to adapt, it’s a nonsense designed to make the case for business as usual.
Human beings will continue to adapt to the changing climate in both ordinary and astonishing ways. But the most sensible form of adaptation is surely to adapt our energy systems to emit less carbon pollution. After all, if we adapt in that way, we may avoid the need to change in so many others.

Population Change
Why is the world’s population growing? The answer is not what you might think.The reason for the explosion is not that people have been reproducing like rabbits,but that people have stopped dropping dead like flies.In 1900,people died at the average age of 30.By 2000 the average age was 65.But while increasing health was a tupical feature of the 20th century,declining birth rate could be a defining one of the 21st.
Statistics show that the average number of births per woman has fallen from 4.9 in the early 1960s to 2.5 nowadays.Furthermore,a
