The early-spring phenomenon is advancing at a record rate. There is no better proof that climate change is happening now, especially in northern regions. “When we started studying this, I never would have imagined we’d be talking about a 26-day per decade rate of advance,” according to an ecologist who has been studying the arctic region for 27 years.

An overview of the relationship between climate change and global food supply. Falling yields for important staple crops are a real problem, directly associated with rising temperatures, prompting a pursuit for mitigation practices that include “genotypic solutions.” The author is an Australian professor active in numerous top-level organizations.
—plus, complementing this story is one from World Resources Institute featuring maps that display all of the world’s regions most likely to be affected by water stresses between now and 2030. The connection between food shortages and general destabilization that may often lead to conflicts is emphasized.

A story about improved battery technology that looks unusually convincing. The co-inventor, working at the University of Texas, has terrific credentials, and his new type of solid-state battery is said to have all the answers people are looking for. When will products be ready for the market? “In the short term, they hope to work with battery makers to develop and test their new materials in electric vehicles and energy storage devices.”

A description of massive permafrost thaw slumps and their cause. There are different kinds of permafrost. In most places it is made largely of dirt that has been hard-frozen for many years, while in other places it was formed in and around old lake beds that stayed frozen and thereby remained largely composed of old ice. When these areas finally thaw the “slumps” that appear can be massive in size and are sometimes found on uneven ground allowing the muck to slide away and cause all kinds of damage. This is now occurring with increasing frequency.
—From a related site:
“The research team mapped the distribution of thaw slumps in the NWT, which are indicators of landscapes underlain by thick layers of ground ice. The research shows that areas of high thaw slump density mainly coincide with the margins of the former Laurentide Ice Sheet that covered most of Canada roughly 14,000 years ago. The abundant ground ice along these margins has been preserved by permafrost since the end of the last glaciation. However with climate warming, these ice-rich landscapes are now undergoing dramatic change.”
