1. The Cold Tube cools people through the absorption of their radiant heat while allowing the free circulation of air. It uses less than half the energy of standard air conditioning. https://phys.org/news/2020-09-qa-multiple-benefits-world-air.html

2. The half-degree difference between 1.5C and 2C greatly increases aridity on regions of the earth’s surface. https://phys.org/news/2020-09-additional-huge-effect-global-aridity.html

3. The tipping points of climate systems are thresholds which, once passed, will produce great effects from small prompts.  Tipping points may be connected to others. This article summarizes scientific discussion of the issues. https://www.theguardian.com/science/2020/sep/19/the-tipping-points-at-the-heart-of-the-climate-crisis

4. Arctic sea ice is already below its record minimum of last year. Warm waters are to blame. In a positive feedback, the open water absorbs more solar heat and the reflective ice did and leads to further melting. The Arctic could be transitioning to a new state—that is, passing a tipping point.  https://phys.org/news/2020-09-arctic-sea-ice-increasingly-atlantic.html

5. A six-year NASA study has concluded that busines as usual emissions would result in a little over 15 inches of sea level rise from the polar ice sheets by 2100, in addition to the rise already set in motion and the rise from other sources such as heat expansion. https://climate.nasa.gov/news/3021/emissions-could-add-15-inches-to-sea-level-by-2100-nasa-led-study-finds/

6. Impossible Burgers are increasingly popular, and are typically bought when a meat product would otherwise have been chosen. The environmental advantages are considerable. https://climatecrocks.com/2020/09/21/doing-the-impossible-meatless-burgers-surging/
