[GWSG] Fuel limits; fuel propaganda goals; 0 emissions by 2050 not enough; Cu for Ag; AMOC info

[Tilley, Al]

1. In order to have half a chance to limit heating to 1.5C, we need to leave about 60% of oil and methane 2018 inventory in the ground, and 90% of coal. To have better than 50/50, we need to leave more. https://phys.org/news/2021-09-limiting-fossil-fuel-global.html

2. Climate denial has not been the focus of fossil fuelled propaganda for over a decade. The four dominant objectives of the industry’s campaigns: “redirect responsibility (consumers are also to blame for fossil fuel emissions), push non-transformative solutions (disruptive change is not necessary), emphasize the downside of action (change will be disruptive), and surrender (it’s not possible to mitigate climate change).” Delay is their greatest goal, and threatens disaster. A major theme is wokewashing: the claim or implication that the corporations serve the needs of poor and marginalized communities.  https://www.theguardian.com/environment/2021/sep/09/big-oil-delay-tactics-new-climate-science-denial

3. The AMOC appears to be at or near a tipping point, and other systems are also approaching a sudden and destructive change of state. A focus on net zero emissions by 2050 does not deal with the situation. We should instead embrace a program of radical transformation. We know what we have to do and we have the means to do it: cease burning fossil fuels and draw down from the atmosphere much of the carbon we have released so far. The transition to renewable energy does not require any further technology, nor would a global program of biochar production and kelp permaculture require any further knowledge. https://www.theguardian.com/commentisfree/2021/sep/09/earths-tipping-points-closer-current-climate-plans-wont-work-global-heating

4.  Copper could replace the silver used in solar panels at 1% of the cost if it could be rendered corrosion proof and made to stick more easily to the solar cells. Australian startup SunDrive Solar has found a way to do those things with copper. They still must find a way to put their process into mass production, and may partner with a manufacturer to develop that.  https://www.bloomberg.com/news/articles/2021-09-09/sundrive-solar-startup-beats-china-s-giant-manufacturers-in-efficiency-test?utm_source=facebook&utm_content=business&utm_medium=social&cmpid=socialflow-facebook-business&utm_campaign=socialflow-organic&fbclid=IwAR1eELRfAI4ZKwsvT1YU4BFEmLHrZJBWadzLiXaDz5eROgyIxI_vWQtqPcY

5. Peter Sinclair has assembled some sources on the news that the AMOC is at or near a tipping point. The Niels Bohr Institute’s J. P. Steffens discusses the reciprocal relationship between the polar climates: when Greenland gets colder (as would happen if the AMOC were to tip), the Antarctic heats up (and we could expect melting to accelerate). The Washington Post assembles expert testimony. Finally Michael Mann and other scientific stars discuss the North Atlantic’s Mystery Spot and its implications for the AMOC. https://climatecrocks.com/2021/09/11/amoc-time-study-suggests-ocean-shift-could-be-close/
