Evidence of extreme vulnerability of insect populations to climate change (The Guardian). The number of studies assessing this vital issue is not large, “but those that do exist are deeply worrying…..We are essentially destroying the very life support systems that allow us to sustain our existence on the planet, along with all the other life on the planet. It is just horrifying to watch us decimate the natural world like this.” Birds and other animals that feed on insects are disappearing along with them. https://www.theguardian.com/environment/2019/jan/15/insect-collapse-we-are-destroying-our-life-support-systems
A new study describes the impact of ocean acidification on the base of the marine food chain. The processes involved, which are complicated, cause phytoplankton communities to become unbalanced. “The stimulated growth and persistence of harmful or nuisance algal species has the capacity to throw marine food webs out of whack by changing the export of organic material to deeper waters and decreasing the amount of available zooplankton that many fish and higher level marine predators rely on for nutrition.” Over half of the world’s human population depends on this same food chain for a good part of its nutritional needs.

Permafrost soils are warming up globally at about the same pace as air temperatures. Systematic, comprehensive testing at depth for a full decade over a wide range of locations has produced useful data results. Soils farthest to the north, which contain the largest amount of carbon, are warming the fastest on average—in Siberia, nearly 1C for the decade. Variations in snow cover were found to have a marked effect on results.

Some scientists believe it is still possible to limit the global temperature increase to the 1.5C target set in Paris. This post has a short introduction to their work by Yale e360, including a link to the full study with open access. This is probably the best possible statement of a viewpoint that many other scientists would approach in a more doubtful way.

An exciting piece of news from researchers at the University of Alberta. It is just one step, but that one step is critical, and the ultimate goal is far beyond the dreams of others who work on battery improvements.
