1. The US senate has voted to join 137 other nations in the Kigali Amendment of 2016 to greatly reduce the use of hydrofluorocarbons for refrigeration and air conditioning. HFCs have hundreds to thousands of times the heating potential of CO2. The agreement will have the effect of lessening heating by about .5C at the end of the century. The Agreement amends the Montreal Protocol, which banned chlorofluorocarbons to protect the ozone shield.   https://www.washingtonpost.com/climate-solutions/2022/09/21/kigali-amendment-senate-super-pollutants-climate/?utm_campaign=Carbon%20Brief%20Daily%20Briefing&utm_content=20220922&utm_medium=email&utm_source=Revue%20Daily

2. PhysOrg explains how fridges work, the role of CFCs and HFCs, and what we can use now. (We’re not sure about that.)  https://phys.org/news/2022-09-climate-hfcs-refrigerators-air-conditioners.html

3. Greenland has seen higher-than-average melting this year, with an abrupt spike in September. https://climatecrocks.com/2022/09/24/graph-of-the-week-greenland-september-melt-event/

4. A resilience center serves to protect people from climate disruptions such as heat waves, floods, and power outages. They also serve to provide a focus for building a stronger community by offering such services as after-school programs and job training. Funding such a center is a struggle, but likely to be worth it.  https://www.theguardian.com/us-news/2022/sep/23/california-extreme-heat-resilience-centers

5. As we shift to wind and solar power to power our increasingly electric cars, we should be charging them during the day, perhaps at work, to ensure grid stability, according to a Stanford study. https://techxplore.com/news/2022-09-cars-home-night.html?utm_source=nwletter&utm_medium=email&utm_campaign=weekly-nwletter

6.   The $19.5b allocated to climate-smart farming in the Inflation Reduction Act will generally go to practices which foster soil fertility while reducing fertilizer use. Cover crops and no-till agriculture are surely worth supporting. Still, the act leaves in place provisions which support conventional agriculture, and appears to have little to influence the dietary shift to plant-based food which is necessary for effective climate action. https://www.nytimes.com/2022/09/26/us/politics/climate-smart-farming-agriculture-department.html
