Most of the U.S. is suffering a terrible drought, but scientists believe we may be able to pull water from air and survive the way desert creatures do.

Pulling water from thin air
“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.”
“The new system […] the power of these natural systems […] to collect and direct the flow of condensed water droplets.”
Climate change: How do we know?
“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
“ Increasing water vapor leads to warmer temperatures, which causes more water vapor to be absorbed into the air. “
“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.”
