The history of sustainable development in the United Nations dates back to the United Nations Conference on the Human Environment, held in Stockholm, Sweden, in 1972. The United Nations Conference on the Human Environment was the UN's first major conference on the issue of the environment.
The research involved a device that sprayed sea salt particles into the air from the deck of the USS Hornet, the decommissioned aircraft carrier and museum docked in Alameda. This aerosol may one day be used to brighten clouds, so they can reflect sunlight away from Earth and temporarily cool the planet.
Researchers from the University of Washington were performing the climate experiment on the flight deck of the USS Hornet Sea, Air & Space Museum in Alameda to determine if salt particles can increase the sun reflectivity of clouds, as part of its Marine Cloud Brightening Program.
Salts. The most common chemicals used for cloud seeding include silver iodide, potassium iodide and dry ice (solid carbon dioxide). Liquid propane, which expands into a gas, has also been used. It can produce ice crystals at higher temperatures than silver iodide.
In the early hours of this morning, City of Alameda City Council members voted unanimously to call off the University of Washington's Marine Cloud Brightening Project (MCBP), which had been conducting a geoengineering experiment off the coast of California.
Solar geoengineering refers to proposals to reduce global warming by reflecting a portion of sunlight back into space before it reaches the Earth's surface. In its best-known form, this means using high-flying aircraft to inject tiny reflective particles into the upper atmosphere.
