During the 1999/2000 winter, the nasa-sponsored sage iii ozone loss and validation experiment (solve) and european union-sponsored third european stratospheric experiment on ozone (theseo-2000) obtained measurements of ozone, other atmospheric gases, and particles using satellites, airplanes, balloons, and ground-based instruments.
Tropospheric ozone is a greenhouse gas and initiates the chemical removal of methane and other hydrocarbons from the atmosphere thus, its concentration affects how long these compounds remain in the air. Warm ocean causing most antarctic ice shelf mass loss (nasa is so cold and dense that it spreads out along the bottom all of the major ocean basins except the north atlantic and arctic multiple recent reports provide strong evidence that the formation of antarctic bottom water has slowed dramatically in response to massive subsurface. Ozone depletion and climate change, or ozone hole and global warming in more popular terms, are environmental challenges whose connections have been explored and which have been compared and contrasted, for example in terms of global regulation, in various studies and books.
