Huenda wewe ndiye msanii. Huyu Mh. anayewaumiza vichwa hata mnakosa usingizi amesoma sana, na anajua anaongea nini kwani ametembea nchi mbalimbali na kuona wenzetu wanaishi vipi pindi hali ya hewa inapobadilika na kuwa kavu.
ANGALIA WENZETU WALIVYO MBALI ZAIDI LAKINI SISI TUNAWEKA SIASA HATA KWENYE JAMBO LINALOGUSA MAISHA YA WANANCHI KWA SABABU TU NI WA CHAMA TAWALA HUWA WEWE NI MALAIKA HUKOSEI NA PIA USISHAURIWE HATA UKIAMBIWA KULA UCHAFU ULE USIOLIKA NA MTU KUTEMA MATE AKIUONA KWA AJILI YA CHAMA, UTAKUBALI KULA KWA SABABU YA CHAMA.
IFIKE WAKATI TUBADILIKE NA TUWE WAKWELI. ENDAPO KAMA TUNGEISHAURI SERIKALI KUWA NA BAJETI YA MAAFA MBONA INAWEZEKANA KUTENGENEZA MVUA????
LAKINI TUNAWEKA SIASAMBELE.

Rain Making and Man-Made Weather in China
Cloud seeding China is the world's leader in artificial rain making. To induce more rain between April and June, when much of China suffers from drought, scientists use aircraft, rockets, artillery and even land-based furnaces to propel small amounts of silver iodine or liquid nitrogen into certain types of moisture-laden clouds which produce crystals that turn into rain as they fall into warmer areas below. Depending on the type of cloud, dry ice and salt can also be added to enhance the effort. Rain-making doesn't come without its costs. Occasionally villagers complain of rain-inducing missiles crashing through the roofs of their homes.
How Cloud Seeding Works: 1) Silver iodide is fired into cloud using flares on planes or from the ground. 2) Water droplets then attach to these particles. 3)They fall as snow if surface temperatures are below or near freezing, or as raindrops at warmer temperatures. 4) Heat released as the droplets freeze boosts updrafts, which pull more moist air into the cloud.
Cloud seeding was pioneers in the United States in the 1940s. Efforts to control the weather began in the 1950s when Beijing was given access to “cloud seeding” data from the Soviet Union and today is kept alive at research facilities such as the Beijing-based Study Institute of Artificial Influence on the Weather.
Rain Making in China
China boasts the largest rainmaking program in the world ahead of Russian and Israel. According to the Weather Modification Research Center, China employs for than 50,000 people for the task and uses an arsenal that includes 6,781 artillery guns, 4,110 rocket-launchers. 30 modified planes, and some on trucks, are employed in the struggle to extract rain. Guns with shells that explode like fireworks are best for extracting rain from small, clouds while rockets, sometimes shot hundreds at a time, and planes are better for spreading chemicals over a wide area. The techniques are not used for bringing rain clouds to parched areas, only inducing clouds already in a given place to produce rain.
China is thought to have the world's largest rain-making operation. It has an annual budget of over $100 million and offices in 30 provinces. Between 1995 and 2003, China spent $266 million on rainmaking and $500 million on it between 2003 and 2008. Chinese scientists claim that cloud-seeding can increase precipitation in targeted areas by 10-15 percent.
They claim Chinese rainmakers have increased rainfall by 210 billion cubic meters---enough to meet the annual needs of 400 million of China's 1.3 billion people between 1995 and 2004. The current five year plan calls for an increase of man-made rain of 50 billion cubic meters a year---nearly enough to fill the Yellow River.
