Scientists model how Antarctic meltwater from specific locations could affect the Antarctic Bottom Water, ocean temperatures, and salinity.
As ice melts, multiple models yield more detailed route predictions than any single model alone.
Increasing ice temperatures and decreasing ice viscosities could lead to "thermal-viscous collapse" of the Greenland ice sheet, raising sea levels as much as 51 centimeters over the next 500 years.
Computer simulations show that adding tiny droplets of ice to the atmosphere during the spring could help eliminate chlorofluorocarbons and repair the hole in the ozone layer.
A detonation of less than 0.03% of the current global nuclear arsenal could cause fires that clog the air with soot. This soot could block solar radiation, leading to worldwide crop shortages.
