Black carbon caused by burning fossil fuels makes a substantial contribution to Arctic warming (Inside Climate News). Researchers have learned that this source of black carbon (or soot) deposits on icy or snowy surfaces is even greater than that from wildfires, which comes as a surprise. The deposits darken the surface so that sunlight is captured rather than reflected, setting off significant warming processes. Cutting off the source of this pollution would serve as a companion to reducing CO2 emissions as a means of curbing climate change in a region of very high sensitivity.

A new overview addresses the trend of nutritional needs in Africa (reliefweb). The annual report showed an overall rise in malnutrition for the year, furthering a trend that began in 2017 after many years of decline. “Today, a fifth of Africans are undernourished, representing a staggering 257 million individuals.” Among the various causes that are noted, “Climate variability and extremes, in part due to climate change, is a present and growing threat to food security.”

What coal mining does to water supplies for people living in Appalachia (BBC News). This fine piece of journalism could be repeated in places all over the world. It provides much added weight to all of the other reasons for completely eliminating this particular source of dirty energy.

How Trump’s EPA has backed away from regulating toxic chemicals (Yale e360). Another piece of fine journalism, with a story that exactly parallels the administration’s decisions to hire fossil fuel lobbyists to supervise the regulation of energy provision. There is simply no interest in protecting either human health of the environment, a position that seems irrational but can still be explained in an understandable way. Over 40% of the American people say they support this government, which is less easily explained.

Can geoengineering provide a solution to climate change? A new report expressing considerable doubt has been issued by a well-established, non-profit environmental law firm. Their report “makes the case that the fossil fuel industry prefers geoengineering as an approach for addressing climate change because it allows the industry to keep arguing for continued fossil fuel use…..The authors of the new CEIL report argue that current climate goals are achievable without relying on geoengineering but that any scenario for meeting them would require an early, rapid phase-out of fossil fuels.” https://www.desmogblog.com/2019/02/13/ciel-report-fossil-fuels-geoengineering-climate-risky-distraction?

“Carbon farming” has great worldwide potential for storing more carbon in soil (Think Progress). People interviewed for this report, plus those in the 4-minute video, believe that “billions of acres” of agricultural land have been seriously depleted over time and are capable of restoration, by as much as fifty tons of carbon (or more) that can be added to amounts retained in storage per acre. We presently add about five billion tons of carbon element to the atmosphere each year, so do the math.
