Years of drought and climate change are causing water resources to dwindle in the Colorado River Basin. But farmers and scientists are collaborating to learn how to grow crops with less water.
Climate Change
Volcanoes’ Future Climate Effects May Exceed Standard Estimates
Future releases of sulfur dioxide from volcanoes will likely be higher than the reconstructed historical levels currently used for climate predictions.
Tracking Human CO2 Emissions from Medium-Sized Cities
Atmospheric inverse models, combined with observations, successfully tracked modest CO2 emission reductions in Salt Lake City during the first COVID-19 lockdown in 2020.
Major Lakes Have Suffered Major Water Losses over the Past Few Decades
A new study shows that losses are global in both arid and humid regions and could have significant impacts on a quarter of Earth’s population.
Protecting the Ozone Layer Is Delaying Arctic Melting
The Montreal Protocol has unintentionally slowed global warming and pushed back the first ice-free Arctic summer by 15 years, according to new research.
Fixing the Flawed Colorado River Compact
The 1922 Colorado River Compact ignored available science and overallocated the river’s water, a decision whose effects reverberate today. Now there’s an opportunity to get things right.
Reducing Aerosol Climate-Forcing Uncertainty: A Three-Way Street
To reduce persistent aerosol-climate-forcing uncertainty, new in situ aerosol and cloud measurement programs are needed, plus much better integration of satellite and suborbital measurements with models.
As Wildfires Grow, So Could Methane Emissions
Wildfires that wreaked havoc on California in 2020 filled the atmosphere with a potent greenhouse gas.
Warming Waters Drive Some Mariners to Piracy
As fish production waxes and wanes with climate change, so too does the risk of maritime piracy in East Africa and the South China Sea.
A 150-Day Periodicity is Revealed in the Southern Extratropics
An internally generated 150-day periodicity is newly identified in the Southern Hemisphere extratropical large-scale atmospheric circulation, which arises from the annular mode’s propagating regime.
