Cloud clustering causes more extreme rain      (via sciencedaily.com)     Original source 

Understanding cloud patterns in our changing climate is essential to making accurate predictions about their impact on society and nature. Scientists published a new study that uses a high-resolution global climate model to understand how the clustering of clouds and storms impacts rainfall extremes in the tropics. They show that with rising temperatures, the severity of extreme precipitation events increases.

Air pollution hides increases in rainfall      (via sciencedaily.com)     Original source 

In a new study, researchers broke down how human-induced greenhouse gas and aerosol emissions influence rainfall in the United States. Greenhouse gas emissions increase rainfall, while aerosols have a long-term drying effect as well as short-term impacts that vary with the seasons. As aerosols decrease, their long-term drying effect will likely diminish, causing rainfall averages and extremes to rapidly increase.

Towards A Better Way of Releasing Hydrogen Stored in Hydrogen Boride Sheets      (via sciencedaily.com)     Original source 

Hydrogen stored in hydrogen boride sheets can be efficiently released electrochemically, report scientists. Through a series of experiments, they demonstrated that dispersing these sheets in an organic solvent and applying a small voltage is enough to release all the stored hydrogen efficiently. These findings suggest hydrogen boride sheets could soon become a safe and convenient way to store and transport hydrogen, which is a cleaner and more sustainable fuel.
