Over the past 40 years, climate change has led to the shrinking of the Northern Hemisphere's seasonal snowpack. @dartmouth researchers documented these losses, which could put water supplies serving 100s of millions of people at risk. #ClimateScienceSunday home.dartmouth.edu/news/2024…

Hurricanes are destructive now, but may get worse. Scientists @PNNLab found that changes in coastal conditions since 1979 have driven nearshore hurricanes to intensify faster. If warming trends continue, the rate will keep climbing. #ClimateScienceSunday pnnl.gov/news-media/coastal-…

Wetlands are the biggest natural source of the greenhouse gas methane and climate change is driving them to emit more of it. @BerkeleyLab scientists found that wetland methane emissions in the Boreal-Arctic increased ~9% since 2002. #ClimateScienceSunday newscenter.lbl.gov/2024/02/1…

The Atlantic Meridional Overturning Circulation moves heat northward & helps maintain a temperate climate over Europe and North America. Scientists @PNNLab used climate models to explain its weakening and potential collapse. #ClimateScienceSunday pnnl.gov/publications/differ…

Do we need a new category to describe hurricanes in a warming world? While the National Hurricane Center uses Categories 1-5 based on wind speed, researchers @BerkeleyLab & First St Foundation suggest a need for a Category 6. #ClimateScienceSunday newscenter.lbl.gov/2024/02/0…

To improve climate resilience, planners are choosing new types of roofs for buildings. With @NERSC & @argonne_lcf, scientists @argonne found cool roofs, green roofs & roofs with solar all lowered AC needs but cool roofs did the most. #ClimateScienceSunday anl.gov/article/can-a-roofs-…

The atmospheric boundary layer is familiar to you, even if you don't realize it. It's where most weather occurs. Zhien Wang @stonybrooku studies this area to increase our knowledge of cloud properties and processes. #ClimateScienceSunday arm.gov/news/features/post/9…

It’s important to understand “how land use affects the climate at a neighborhood scale" - Katia Lamer @BrookhavenLab. She's the co-investigator on CoURAGE, an @armnewsteam field campaign that is collecting data in Baltimore. #ClimateScienceSunday arm.gov/news/facility/post/9…

Excess ammonia can contribute to water pollution, poor soil quality, & climate change. Agriculture is the biggest source. But a team with scientists @ORNL found that we could cut ammonia emissions by 38% without limiting fertilizer. #ClimateScienceSunday ornl.gov/news/reaping-agricu…

Increasing 9% since 2002 doesn't seem like a big jump, but when it's an increase in a powerful greenhouse gas, that's bad news. @BerkeleyLab scientists found that methane emissions from boreal Arctic wetlands are increasing. #ClimateScienceSunday newscenter.lbl.gov/2024/02/1…

Climate change caused by increases in greenhouse gas emissions should increase rainfall. Strangely, it hasn't. @BerkeleyLab researchers found that aerosols caused by air pollution (like in smog) may have masked the effect. #ClimateScienceSunday newscenter.lbl.gov/2024/02/2…

Methane is 28 times more potent of a greenhouse gas than carbon dioxide. @ORNL scientists combined a new modeling framework and field data to improve predictions of methane from soils in coastal ecosystems. #ClimateScienceSunday ornl.gov/news/coastal-chemis…

The Amazon is both a vast rainforest and home to a city of 2 M people. That makes it a terrific place to study both unpolluted air and a plume of pollution, as scientists with @armnewsteam did for the GoAmazon2014/15 field campaign. #ClimateScienceSunday arm.gov/news/features/post/9…

Even tiny organisms have a big impact, like soil microbes. But previous climate simulations didn't include them. To improve these models, @BerkeleyLab & @Livermore_Lab scientists are using microbes' DNA to study how they use carbon. #ClimateScienceSunday newscenter.lbl.gov/2024/02/0…

Happy birthday to the Energy Exascale Earth System Model (E3SM)! The vision for a simulation designed to run on exascale computers began in 2014. The team will soon release version 3, which is faster & more accurate than ever before. #ClimateScienceSunday e3sm.org/e3sm-a-decade-of-pr…

Science can't determine policy, but it can inform it. For the 1st time, @ORNL was an Observer Organization at the COP 28 climate change negotiations. Scientists from the lab provided expertise outside of the formal negotiations. #ClimateScienceSunday ornl.gov/news/qa-researchers…

As policymakers discuss how to deal with climate change, science can play an important role. Extreme event attribution research @BerkeleyLab & elsewhere can inform talks about financial compensation to the most affected countries. #ClimateScienceSunday cs.lbl.gov/news-media/news/2…
