Soil restoration provides an important opportunity to remove carbon from the atmosphere (Phys.org)  “Restoring and protecting the world’s soil could absorb more than five billion tonnes of carbon dioxide each year—roughly what the US emits annually—new research showed Monday…..Most of this potential, around 40 percent, can be achieved simply by leaving existing soil alone—that is, not continuing to expand agriculture and plantation growth across the globe…..soil restoration would have significant co-benefits for humanity, including improved water quality,  food production and crop resilience.”  In every country, government assistance would be of great help in getting this done, and clearly needs to be stepped up.

Coronavirus studies help to demonstrate the key role of air pollution as a cause of premature death (The Guardian).  There is a great deal of irony involved in this story, in part because air pollution by itself, in the absence of any contagious disease, is known to cause at least 8 million early deaths globally every year, and no one gets very excited by that number.  Several past studies are noted  in this article:  “There is evidence from previous coronavirus outbreaks that those exposed to dirty air are more at risk of dying.”  The current outbreak, meanwhile, is having an unusual effect on societies everywhere that is resulting in greatly reduced amounts of air pollution, leading to this observation:  “It seems clearly incorrect and foolhardy to conclude that pandemics are good for health…..But the calculation is perhaps a useful reminder of the often-hidden health consequences of the status quo, ie, the substantial costs that our current way of doing things exacts on our health and livelihoods.”

Researchers now believe sea-ice loss at both poles causes significant warming of tropical ocean waters, further affecting the pace of climate change globally (University of California – San Diego).  “They found that Antarctic sea ice loss combines with Arctic sea ice loss to create unusual wind patterns in the Pacific Ocean that will suppress the upward movement of deep cold ocean water. This will trigger surface ocean warming, especially in the eastern equatorial Pacific Ocean. Warming there is a well-known hallmark of the El Niño climate pattern that often brings intense rains to North and South America and droughts to Australia and other western Pacific countries.”

Samsung says it has developed a car battery with a range of 500 miles on one charge (OilPrice).  “One of the latest entrants in the heated race for higher-performance battery pack technology is a new type of solid-state battery with high energy density, half the size of a typical lithium-ion battery, and the potential to make the 500-mile range possible.”  It is also said to be safer and more durable than existing lithium/ion batteries.  https://oilprice.com/Energy/Energy-General/New-Solid-State-Battery-Tech-Promises-500-Mile-Range-EV.html

A new study is full of facts about the disparity in energy footprints (University of Leeds).  Transportation leads the way, as can be noticed wherever there is a rise in income and wealth.  “Indeed, the researchers found that 187 times more vehicle fuel energy is used by the top 10% consumers relative to the bottom 10%.”  Eighty-six different countries were studied.
