Ships Now Spew Less Sulfur, but Warming Has Sped Up
New findings document fewer ship tracks, reduced cloud cover, and boosted warming after ship emissions regulations took effect in 2020.
Current Predictions may Underestimate Precipitation Increase with Climate Change
A recent study suggests a higher global mean precipitation increase and narrows the uncertainty range.
City Sprawl Now Large Enough to Sway Global Warming Over Land
Once thought to cover too little of the Earth’s surface to affect climate at larger scales, new work finds that city sprawl does add to global warming—over land, at least.
Five PNNL Earth Scientists Participated in a Department of Energy Workshop on Coastal Systems
Five PNNL scientists participated in an invitation-only Department of Energy-sponsored workshop on coastal systems.
Slowing Climate Change is Possible—Here’s How Nations Could Make it Happen
Policy changes in power, energy, buildings, and more could help slow global temperature rise, according to a new report with co-authors from PNNL’s Joint Global Change Research Institute.
Predicting the Intensity of Hurricanes
A new model accounts for co-occurring environmental parameters to improve predictions of a hurricane’s intensification.
Peak Water: Do We Have Enough Groundwater to Meet Future Need?
A new study suggests accessing groundwater in key regions could become prohibitively expensive as lower-cost stores are used up.
Beyond Higher Temperatures: Preparing for National Security Risks Posed by Climate Change
Beyond melting ice and higher temperatures: On Earth Day, scientists consider how climate change will affect national security.
Coastal Hurricanes Around the World are Intensifying Faster
New work finds hurricanes are intensifying faster close to the coast—a trend that’s likely to ramp up in a warmer world.
Inaugural Gordon Bell Prize for Climate Modeling Awarded to Multi-Institutional National Laboratory Team
A 19-person, multi-institutional national laboratory team received the inaugural Gordon Bell Prize for Climate Modeling from the Association for Computing Machinery for their work on more accurately modeling deep convective clouds.
