CANADA and UNITED STATES OF AMERICA
Agreement relating to the exchange of information on
weather modification activities. Signed at Washington
on 26 March 1975 http://untreaty.un.org/unts/1_60000/27/20/00052955.pdf

Various ideas for manipulating hurricanes have been suggested. One TV show[17] explored various ideas such as:
Weather control and law
US and Canada agreement
In 1975, the US and Canada entered into an agreement under the auspices of the United Nations for the exchange of information on weather modification activity.[18]
1977 UN Environmental Modification Convention
Weather control, particularly hostile weather warfare, was addressed by the "United Nations General Assembly Resolution 31/72, TIAS 9614 Convention[19] on the Prohibition of Military or Any Other Hostile Use of Environmental Modification Techniques" was adopted. The Convention was: Signed in Geneva May 18, 1977; Entered into force October 5, 1978; Ratification by U.S. President December 13, 1979; U.S. ratification deposited at New York January 17, 1980.[20]
US National Oceanic and Atmospheric Administration
In the US, the National Oceanic and Atmospheric Administration regulates weather control projects, under authority of Public Law 205 of the 92nd Congress.
US Legislation
The Space Preservation Act was proposed "to preserve the cooperative, peaceful uses of space for the benefit of all humankind by permanently prohibiting the basing of weapons in space by the United States, and to require the President to take action to adopt and implement a world treaty banning space-based weapons."[21]
2005 U.S. Senate Bill 517 and U.S. House Bill 2995 U.S. Senate Bill 517[22] and U.S. House Bill 2995[23] were two bills proposed in 2005 that would have expanded experimental weather modification, to establish a Weather Modification Operations and Research Board, and implemented a national weather modification policy. Neither were made into law. Former Texas State Senator John N. Leedom was the key lobbyist on behalf of the weather modification bills.
2007 U.S. Senate Bill 1807 & U.S. House Bill 3445 Senate Bill 1807 and House Bill 3445, identical bills introduced July 17, 2007, proposed to establish a Weather Mitigation Advisory and Research Board to fund weather modification research [24][25]
Future aspirations
Climatologists have simulated hurricane control based on selective heating and cooling (or prevention of evaporation).[26] Futurist John Smart has discussed the potential for weather control via space-based solar power networks. One proposal involves the gentle heating via microwave of portions of large hurricanes. Such chaotic systems may be susceptible to "side steering" with a few degrees of increased temperature/pressure at critical points. A sufficient network might keep the largest and most potentially damaging hurricanes from landfall, at the request of host nations. Blizzards, monsoons, and other extreme weather are also potential candidates for space-based amelioration.[citation needed] If large-scale weather control were to become feasible, potential negative implications may include:
For the 2008 Olympics, China had 30 airplanes, 4,000 rocket launchers, and 7,000 anti-aircraft guns to stop rain. Each system would shoot various chemicals into any threatening clouds to shrink rain drops before they reach the stadium.[28]
