Used with permission of Extinction Rebellion. Dr. Ye Tao gives an excellent presentation weaving in social equity, and the need for nonprofit science-based solutions benefiting people in all countries such as mirrored roof tiles in India to reduce suffering during extreme heat events.
March 6, 2022 Update: Dave Borlace's Just Have a Think posted a video Can we survive the coming decades? about the IPCC's second part of the Sixth Assessment Report, Climate Change 2022: Impacts, Adaptation and Vulnerability, Summary for Policy Makers. Long ago I noted Borlace as top "Explainer" on my "Updated Best Practices for Climate Crisis."
The end of the Extinction Rebellion above video mentions Kim Stanley Robinson's climate novel The Ministry for the Future in which a heat wave kills 20 million people in India. Interviewed by Amy Brady October 27, 2020 in Burning Worlds at Chicago Review of Books, Robinson responded, "Recent studies of the effect of heat and humidity combined have found that a temperature index of 'wet-bulb 35' (which would be about 95 degrees Fahrenheit with 100% humidity, and then higher temperatures combined with slightly lower humidities [ . . . ]), are fatal to humans who can’t take shelter in air-conditioned spaces. But in heat emergencies like this, power systems are likely to be overwhelmed and go down, at which point even people unclothed, in the shade, and fanning themselves, would still die, in a kind of slow parboiling that the body just can’t handle [ . . . . ] I remain terrified that something like this opening scene might happen in the coming decade."
In the Extinction Rebellion video Dr. Ye Tao says, "Any form of direct air capture by industrial method will not be able to work at scale, and to make a measurable impact to the climate crisis in less than several centuries of time. The basic reason is the process of demixing the air is a highly energy-intensive process. Just imagine if you had to separate a pile of well-mixed salt and pepper. So to create order out of disorder takes a lot of energy, and that is guaranteed by the laws of thermodynamics. So it doesn't really matter how much engineering you put onto it. We need an operation the size of the U. S. Military six thousand years [ . . . ] to really achieve what these companies are calling for."
This fits what Agence France-Presse wrote at The Guardian September 8, 2021, in "World’s biggest machine capturing carbon from air turned on in Iceland." The article notes, "Constructed by Climeworks, when operating at capacity the plant will draw 4,000 tonnes of carbon dioxide out of the air every year, the companies say. [par break] According to the US Environmental Protection Agency, that equates to the emissions from about 870 cars. The plant cost between US$10 and 15m to build, Bloomberg reported."
Three posts below I wrote, "[ . . . ] Ye Tao, RF Alumnus of Rowland Institute at Harvard, [ . . . ] I noted as a top 'Innovator' on my 'Updated Best Practices for Climate Crisis.'" This was for his video posted January 29, 2020, "Shocking Facts About Climate Change & A Possible Solution [ . . . ]"
