Night-time heat significantly increases the risk of stroke      (via sciencedaily.com)     Original source 

Researchers show that nocturnal heat significantly increases the risk of stroke. The findings can contribute to the development of preventive measures: With them, the population can better protect themselves against the risks of climate change with increasingly frequent hot nights. In addition, knowledge of the consequences of hot nights can improve patient care.

Warming climate intensifies flash droughts worldwide      (via sciencedaily.com)     Original source 

Sudden, severe dry spells known as flash droughts are rising in intensity around the world, with a notable exception in mountainous Central Asia, where flash drought extent is shrinking, according to new research. Heat and changes to precipitation patterns caused by a warming climate are driving these trends, the study found.

Electric school buses may yield significant health and climate benefits, cost savings      (via sciencedaily.com)     Original source 

Replacing diesel school buses with electric school buses may yield up to $247,600 in climate and health benefits per individual bus, according to a new study. The researchers found that these benefits -- including fewer greenhouse gas emissions and reduced rates of adult mortality and childhood asthma -- and their associated savings are strongest in large cities and among fleets of old (2005 and before) buses.
