Cambodia's Cimate Change Impacts


   The IPCC report states that cold days will decrease in frequency in Asia and Winter precipitation will increase in Southern Asia and also that the monsoon strength will be decreased. The change in Pacific ocean circulation is expected to affect the southwest monsoonal flow which highly influences the precipitation in Southern Asia. The temperature in Asia is also expected to rise 2 to 4 degrees Celsius. Also, because the majority of Asia consists of third world countries, there is a lack of data to support the IPCC climate models there for their projections.
   It is expected that by 2050 more than a billion people could be affected by the availability of freshwater after glacier melt in the Himalayas and a decrease in river flows. The increased temperature of coastal waters will increase cholera, an infection in the small intestine which causes diarrhea, dehydration,  and in some cases death, by an increase in cholerea bacteria.
   With high confidence the IPCC report states that sea-level rise will be responsible for the loss of ecosystems like coral reefs and sea-side cities. One million people are expected to be affected by flooding due to sea-level rise. Sever water stress will cause many health problems for the people of Asia. They also expect that the management of natural resources will improve and environmental risks will not be over looked as they are today. The areas in Asia that are tropical, like much of Cambodia, will have an increased risk of sever weather such as typhoons, floods, and other storms. Due to drought, agriculture production in Asia will decrease affecting the many people are dependent on the climate and agriculture.
  The most interesting threat to my country is drought. So many people in Cambodia rely on rain waters for their crops. The drought combined with increase in population will affect more than an estimated one billion people by the year 2050 (IPCC Report 2007). These droughts will affect food and water security in Cambodia. This will also affect the poverty and health levels of Cambodians. The Mekong river basin is the fuel for crops in the region's capital of Phnom Penh. Currently, the East Mekong Delta floods and dries with the monsoons. After temperatures rise, many expect that the monsoons will change there for influencing the Mekong river and millions of lives.

Cambodias changing climate

 
 In 1968, Cambodia began a 3 year spike in CO2 emissions. In this year, President of the United States also announced that he was initiating bomb raids in Cambodia because they believed the Vietnamese were  supplying their troops from there. In 1970, as the CO2 emissions of Cambodia begin to decline, US troops are pulled out of Cambodia.
In Cambodia today, their per capita of CO2 emissions is .33. Compared to the per capita of the United States which is 4.3 metric tons of Carbon, which is .077%, less that 1/8 of that of the United States. Cambodia is 182 of 215, near the bottom of the list of carbon producers. In comparison, the United States is number 12 on the list of contributors, which is much higher than that of Cambodia. Cambodia's lack of CO2 emissions may be due to the fact that the people that live here do not have money to buy things like car, which are responsible for a large amount of CO2 emissions in many countries (cdiac.ornl.gov) In 2008 Qatar was the biggest emitter of CO2 at 14.58 metric tons of Carbon per capita. China's is 1.43 but their population is 1,338,000,000 so their carbon emissions is actually much higher, even though their rank on the list is of carbon emissions is number 78. Cambodia's cumulative carbon contribution is 15030 tons of carbon. China's is 36152087, Kenya
