From Vox, a synopsis of the world’s current (bleak) climate situation, in three charts. Current policies and pledges both require sharp revisions, with little time for delay. The energy chart has a vivid reminder of the long road ahead for wind and solar if they are to replace all fossil fuels and probably nuclear as well, with hydro not going anywhere. In the national growth category, note that “all other” is the largest of all, and also the fastest growing. https://www.vox.com/energy-and-environment/2018/4/30/17300946/global-warming-degrees-replace-fossil-fuels

Over the next ten days representatives from 193 nations will be meeting in Bonn, where they have an opportunity to advance some agreements that would affect future climate policies and pledges. “The talks are aimed at getting governments to be far more ambitious than their current national plans for greenhouse gas emissions cuts.”

A new study concerning health effects for people living near fracking wells shows disturbing results. The study tested 23 chemicals that are known endocrine disruptors, which interfere with the proper functioning of hormones, and are commonly found in groundwater surrounding fracking operation sites. More than 17 million persons in the US could be exposed. “The study is just the latest concern for people near fracking sites. Previous studies have found associations between living near fracking sites and birth defects, prostate and breast cancer, asthma, and acute lymphocytic leukemia.”

An unusual reason for why biofuels do not save the amount of emissions that are claimed. “Many scientists and environmental groups say it is unrealistic to measure the carbon intensity of biofuels without also measuring how the use of crops like corn or canola for fuel, instead of food, might be causing the conversion of land elsewhere in the world to agriculture to compensate for the drop in food crops. That “indirect” conversion may result in environmentally destructive behaviour like cutting down forests or digging up grasslands, they say. These activities release large stores of carbon into the atmosphere, which may partially or fully negate the emissions savings that biofuels are supposed to offer.”
How microplastic pollution does harm to animal life. This critically important field of study is beginning to obtain reliable answers. A new report offers a summary of the information published by a range of reports that were more tightly focused. The most significant harm is apparent at the level of zooplankton, at the very bottom of the food web, which should likely result in food shortages up the line.
