Two recent papers in Earth's Future discuss the addition of a new epoch to the geological timescale.
Models showed that approximately 93% of crop losses over the rest of the century could be caused by non–carbon dioxide emissions, the most damaging of these being methane.
Grouping targets that need to be hit into composite goals may help countries evaluate their progress toward sustainable development targets laid out by the United Nations.
Reducing emissions of short-lived gaseous sulfur pollutants from power plants had an immediate, local benefit, but controlling longer-lasting harmful particulate matter will require regional action.
In tandem, two strategies could lower water consumption by 28% and ensure better water supply for more than 600 million people.
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.
