GLOBAL WARMING EFFECT

















After years of debate, consensus among most of the world's scientists holds that we are warming the planet. Unless we take steps now to curb global warming, our way of life, our planet, and our children are all in grave danger. There is hope. Each us can make simple decisions that will reduce global warming pollution.


The biggest impact of climate change falls on the poorest countries. These extracts from OneWorld Country Guides offer a glimpse into the inconvenient collateral damage of global warming. Ill-prepared even to assess the risks let alone adapt to them, these developing countries face disruption to their poverty reduction plans whilst those most responsible for the carbon footprint allow domestic concerns to stall negotiations.

SOME DISASTERS OCCURRED DUE TO GLOBAL WARMING

On October 8, a magnitude 7.6 earthquake struck Pakistan, India and Afghanistan—killing at least 43,000 people and leaving more than 3 million people homeless. Residents of the affected region are no stranger to suffering, having been at the epicenter of a tense political conflict for more than 50 years. Natural disasters have the potential to destroy dwellings, damage livelihoods, and spark disease epidemics. In some cases, however, natural disasters create suffering that cuts across the divides of conflict, prompting common relief needs and opening paths to reconciliation.

EARTHQUAKE IN CHINA

CHENGDU, China - A powerful earthquake toppled buildings, schools and chemical plants Monday in central China, killing more than 8,700 people and trapping untold numbers in mounds of concrete, steel and earth in the country's worst quake in three decades.

The 7.9-magnitude quake devastated a region of small cities and towns set amid steep hills north of Sichuan's provincial capital of Chengdu. Striking in midafternoon, it emptied office buildings across the country in Beijing and could be felt as far away as Vietnam.

Xinhua reported 8,533 people died in Sichuan alone and 216 others in three other provinces and the mega-city of Chongqing.



INCREASED EVAPORATION




















Over the course of the 20th century, evaporation rates have reduced worldwide this is thought by many to be explained by global dimming. As the climate grows warmer and the causes of global dimming are reduced, evaporation will increase due to warmer oceans. Because the world is a closed system this will cause heavier rainfall, with more erosion. This erosion, in turn, can in vulnerable tropical areas (especially in Africa) lead to desertification due to deforestation. On the other hand, in other areas, increased rainfall lead to growth of forests in dry desert areas.

Scientists have found evidence that increased evaporation could result in more extreme weather as global warming progresses. The IPCC Third Annual Report says: "...global average water vapor concentration and precipitation are projected to increase during the 21st century. By the second half of the 21st century, it is likely that precipitation will have increased over northern mid- to high latitudes and Antarctica in winter. At low latitudes there are both regional increases and decreases over land areas. Larger year to year variations in precipitation are very likely over most areas where an increase in mean precipitation is projected.
