Can Air Be A Water Source During A Drought?
Most of the U.S. is suffering a terrible drought, but scientists believe we may be able to pull water from air to solve our problems.
Pulling water from thin air (Harvard)
"The major challenges in harvesting atmospheric water are controlling the size of the droplets, speed in which they form and the direction in which they flow."
Climate change: How do we know? (NASA)
"Ice cores drawn from Greenland, Antarctica, and tropical mountain glaciers show that the Earth's climate responds to changes in greenhouse gas levels. They also show that in the past, large changes in climate have happened very quickly, geologically-speaking: in tens of years, not in millions or even thousands."
Water Vapor Confirmed as Major Player in Climate Change (NASA)
"Water vapor feedback can also amplify the warming effect of other greenhouse gases, such that the warming brought about by increased carbon dioxide allows more water vapor to enter the atmosphere."
