Extreme temperatures in India; weak monsoon season expected (Phys.org). “Temperatures passed 50 degrees Celsius (122 Fahrenheit) in northern India as an unrelenting heatwave triggered warnings of water shortages and heatstroke…..More than 40 percent of India faces drought this year…..The annual monsoon—which normally brings much needed rain to South Asia—is running a week behind schedule.”

A new study of likely changes in precipitation in different kinds of regions (IOPscience). Globally, the total amount of precipitation is seen to increase in regions of the humid type but not in arid regions, certainly a disappointing conclusion for the latter. On the other hand, arid regions, just like humid ones, are more likely than not to have increases in the number of extreme types of precipitation events that are the cause of problems from flooding and soil erosion.

A different study confirms a steady increase in frequency of torrential downpours since 1964 (Phys.org). This study examined the daily records from each of 100,000 global weather stations.over a fifty-year period. The frequency of events increased decade by decade, which would be virtually impossible under strictly natural circumstances and must therefore be attributed to global warming.

Why the latest advances in flow batteries are so important (Phys.org). In CL#1435 there was a story about technological advances made at Harvard University. Now we are getting news that a German company has dramatically reduced the costs of manufacturing flow batteries and actually has a family of specialty products on the market that are highly competitive with existing lithium/ion batteries. Comparable storage units have essentially the same price but are said to last twice as long. The company is now looking to scale up the size of applications and make still further reductions in manufacturing costs.
