1.  Soil is being lost far faster than it is being formed. An IPCC report underscores the need to convert pastures to forests, cease burning fossil fuels, and stop eating so much meat so that we can exit the current pattern of destruction and begin rebuilding the ability of the earth to sustain us. https://www.theguardian.com/environment/2019/aug/08/climate-crisis-reducing-lands-ability-to-sustain-humanity-says-ipcc

2. The IPCC report above on the threat that the earth is losing the capacity to sustain life seriously underestimates the impact of agriculture—in particular, meat production. A calculation taking land use into account would nearly triple a Briton’s carbon footprint because of the full impact of meat and dairy farming. Eating a couple of pounds of beef releases as much carbon, for example, as driving a new car for a year or taking a round-trip flight from New York to London. Monbiot’s article is worth bookmarking for its assembly of sources on the footprint of food and its analysis of common errors.  https://www.theguardian.com/commentisfree/2019/aug/08/ipcc-land-climate-report-carbon-cost-meat-dairy?fbclid=IwAR1zKGwmNFP6RRyqsnHbzyv-v8nhVCslPVLWvXQx0GxcAxe01ri_9H7sz1k

In its crucial land and climate report, the IPCC irresponsibly understates the true carbon cost of our meat and dairy habits, says Guardian columnist George Monbiot


3. Wildfires are known for releasing great amounts of carbon in their smoke, but the net addition of carbon may be small. The charcoal the fires leave will sequester carbon for hundreds of years. When the charcoal is considered along with the carbon-fixing vegetation which normally follows a fire, the net carbon added to the atmosphere by a fire is greatly reduced. (The article implies, but does not say, that a wildfire could even be carbon negative.) Peat fires, an exception, produce little charcoal.   https://www.sciencedaily.com/releases/2019/08/190805134012.htm

5. Rising heat means more mercury in larger fish, even though mercury emissions are dropping as we cease burning coal. Increasing heat means an increase in appetite, so that the little ones eat more, and the big ones eat more of the little ones. https://phys.org/news/2019-08-climate-human-exposure-toxic-methylmercury.html
