1 Form 5 Geography - Global Warming Topic 1 - Global warming and China Geography News Presentation Charles Lui 5D Jenny Leung 5E

2 Form 5 Geography - Global Warming Topic 1 - Global warming and China Negative Impacts brought by global warming Extreme Weather condition In 2003, the high air temperature in Taipei, Shanghai, Hangzhou, Wuhan Zhejiang and Fuzhou had broken the record by comparing to the past century. In 2004, the high air temperature in Guangzhou had broke its record by comparing to past 53 years. In 2006, the high air temperature in Chongqing had reached 43 degree Celsius. In 2010, the air temperature in southeast China had reached 38 degree Celsius and the precipitation rate is low. High air temperature

3 Form 5 Geography - Global Warming Topic 1 - Global warming and China In 2013, In northeast China, which typically has snowy, cold winters, the average temperature was an icy minus 15.3 degrees Celsius, the lowest in 42 years. Temperatures have dropped down to minus 40 degrees Celsius in eastern Inner Mongolia, northern Xinjiang and the Arctic reaches of northeast China. china-cold-winter-weather.html Negative Impacts brought by global warming Extreme Weather condition

4 Form 5 Geography - Global Warming Topic 1 - Global warming and China frequency of heat waves in summer has increased and droughts have worsened in some areas, especially in northern China temperature anomalies across China between August 5 & 12, 2013 Negative Impacts brought by global warming Extreme Weather condition

5 Form 5 Geography - Global Warming Topic 1 - Global warming and China In 2013 July and the first half of August, eastern China baked in a record-breaking heat wave. Nineteen provinces endured above-normal temperatures. Shanghai broke its all-time record high three times in as many weeks. The current record40.8 degrees Celsius (105.4°F)was set on August 7, At least 40 people have died during the heat wave, including ten in Shanghai The image above shows temperature anomalies across China between August 5 and August 12, 2013, as observed by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASAs Terra satellite.

6 Form 5 Geography - Global Warming Topic 1 - Global warming and China Negative Impacts brought by global warming Extreme Weather condition Red areas are warmer than the long-term average for the week, while cooler-than-average temperatures are blue. While much of China was warm during this period, the worst of the heat wave was concentrated near the coast and in Tibet. This weather pattern is tied to a subtropical high-pressure system parked over southern China. The heat wave was likely worst in Chinas cities, where manmade surfaces absorb heat during the day and cool slowly at night. As a result, cities are warmer during the day and slower to cool at night, making an extended heat wave more uncomfortable, and more deadly, in a city. Heat wave

7 Form 5 Geography - Global Warming Topic 1 - Global warming and China In 2013 August, 26 rivers had been cut off, 65 reservoirs dried up and 1,100 others left with dead storage levels in central China's Hubei Province, dubbed "the land of a thousand lakes. Of those affected, about 4.3 million people live in Guizhou and Hunan provinces, and the rest are in Hubei, Jiangxi and Zhejiang provinces and Chongqing Municipality. The drought has caused direct economic losses of 12.1 billion yuan (1.98 billion U.S. dollars) and affected about 2.09 million hectares of farmland, including 350,000 hectares that have been left unharvestable. 08/06/c_ htm Negative Impacts brought by global warming Extreme Weather condition Drought

8 Form 5 Geography - Global Warming Topic 1 - Global warming and China the snow disaster has became more frequent In November 2013, 50,000 people were mobilized to clear snow in Harbin, capital of Northeast China's Heilongjiang province, after the worst snowstorm in 50 years hit the city for 60 hours. Average daily snowfall in the city proper reached 11.4 mm, the highest level recorded since 1961 when consecutive weather recording began in the city. Residents, police and volunteers helped to clear snow and ice on the streets, and special snow clearing machines and vehicles were also mobilized Negative Impacts brought by global warming Extreme Weather condition Snow disaster

9 Form 5 Geography - Global Warming Topic 1 - Global warming and China Education authorities requested that all kindergartens, primary and high schools in the urban area close as the accumulated snow on streets exceeded 10 cm in some areas. The National Meteorological Center on Tuesday issued a blue alert for snowstorms, forecasting continuous snow in the eastern part of Heilongjiang for the next 24 hours. Snowfall is expected to reach 10 to 14 mm. 11/19/content_ htm Negative Impacts brought by global warming Extreme Weather condition Snow disaster

10 Form 5 Geography - Global Warming Topic 1 - Global warming and China heavy precipitation has increased in nothwest China and caused flooding Ten rounds of rainfall have battered north China's Shandong Province since the beginning of July. The province received mm of rainfall in July, a 50-year high. The heavy rains severely affected 399,000 people and destroyed 440 houses in Shandong. In arid northwest China, Gansu Province received double the average annual precipitation recorded for the past 30 years in July. Arid northwest China is more vulnerable to rainstorm-triggered landslides and torrential flooding, and people there have been warned to enhance their awareness of flood and waterlogging prevention Negative Impacts brought by global warming Extreme Weather condition Heavy Precipitation

11 Form 5 Geography - Global Warming Topic 1 - Global warming and China Twenty-four people died and one person was reported missing after rainstorm-triggered floods and flows of mud and rock hit Tianshui City in Gansu on July 25. Four rounds of downpours swept Tianshui City in July, triggering floods, landslides and mud-rock flows in seven townships and affecting 1.22 million people. there is a trend of increasing extreme weather events in summer 08/06/c_ htm Negative Impacts brought by global warming Extreme Weather condition Heavy Precipitation

12 Form 5 Geography - Global Warming Topic 1 - Global warming and China Negative Impacts brought by global warming Extreme natural disaster Melting Glaciers Since the 19 th century, the average temperature in China increased 0.5~0.8 degrees Celsius. The phenomenon of rising surface temperatures in China is most significant in the Himalayan Mountain region. The air temperature of the Tibetan Plateau is now increasing at the rate of 0.3 degrees Celsius every ten years. Temperature rise of 4 degrees Celsius could trigger rapid melting of glaciers on a global scale. The shrinking of these glaciers leads to: flooding from glacial lakes into the upper reaches of the Yangtze River ‚lower volume of water in the Yangtze's downstream areas.

13 Form 5 Geography - Global Warming Topic 1 - Global warming and China Negative Impacts brought by global warming Extreme Natural disaster Glaciers Lakes Overflow Glaciers melting in the Himalayas could lead to the overflow of 200 glacial lakes and produce large-scale flooding and mudslides in mountainous areas. Areas along the Sichuan-Tibet Highway (Chuan Zhang Gong Lu), the upstream region of Yarkand River, the Eastern part of Pamirs Plateau, and the middle part of Mount Tian have all encountered increasingly frequent and devastating mud slides. E.g. On 10 June 2004, rapid landslides and massive flooding from the River Yi'ong Zangbo in the Tibetan Plateau destroyed major highways and bridges connecting neighboring regions. The massive flood destroyed approximately 10 bridges, 50 miles of highway and hundreds of homes in Tibet.

14 Form 5 Geography - Global Warming Topic 1 - Global warming and China Negative Impacts brought by global warming Extreme Natural disaster Decrease of Water Volume in Major Rivers The shrinkage of the Jianggendiru Glacier and Toutou River, the source of the Yangtze River. Chinese scientists predict that even if global warming stops, one-third of the glacial area in Tibet will disappear by 2050, and half will disappear by Glacial retreat may cause a transformation in the pattern of rivers that currently feed the Yangtze River. If these rivers fail to flow into the Yangtze River, the natural runoff volume of the Yangtze River is likely to decrease by 25 percent in the future. If the Yangtze River runoff decreases, the wetland ecosystem in Qinghaia major migratory bird habitat located in northwestern Chinawill face possible desertification impacts-chinas-environment-biophysical-impacts

16 Form 5 Geography - Global Warming Topic 1 - Global warming and China Global warming leads to higher temperatures, longer summer months and a greater number of heat wave. People tend to use air conditioners or fans longer and refrigerator more intensely. E.g. Power consumption exceeded 50 billion kwh in July in neighboring Jiangsu Province, the highest among all provinces, partly due to the wide use of air-conditioners (http://news.xinhuanet.com/english/china/ /06/c_ htm) As a result, energy consumption and burning of fossil fuels for generating electricity increase. More money is needed to pay for electricity fee. Vicious cycle Negative Impacts brought by global warming Energy Consumption

17 Form 5 Geography - Global Warming Topic 1 - Global warming and China Since there is more frequent extreme climate events and disasters, more money is needed for relief work More money are needed to solve the problem caused by global warming (as mentioned above),it may take heavy financial burden to the Chinese government, and finally lead to Chinas economic loss.
