Time’s up for the COALition that spent more than $500,000 per person last year to incarcerate less than 200 unwanted refugees on Nauru Island

by Ben Doherty & Ben Butler 12/02/2022

Nauru detention centre operator makes $101m profit – at least $500,000 for each detainee: Canstruct International’s holding company has more than $340m in cash and investments, according to accounts filed with regulator

Biden’s climate incentives may show us how it’s done

William P. Hall on February 13, 2022

Biden’s new climate incentives have a good chance to pass Congress, to work in practice, and to give great value for money

by Robinson Meyer 10/02/2022 in The Atlantic

Biden’s Biggest Idea on Climate Change Is Remarkably Cheap: It’s one of the most cost-effective climate policies the U.S. has ever considered, according to a new analysis…. The researchers’ study, which has not been peer-reviewed, finds that the policy’s benefits will be three to four times larger than its costs, creating as much as projected $1.5 trillion in economic surplus while eliminating more than 5 billion tons of planet-warming carbon pollution through 2050.

New liquid-based CO₂ capture tech for industrial emissions

William P. Hall on February 13, 2022

Shows capacities for high CO2 capture under power plant operating conditions, minimizing energy-intensive temperature swings of other techs

by Mohen S. Yeganeh, et al. 11/02/2022 in Science Advances
Solid with infused reactive liquid (SWIRL): A novel liquid-based separation approach for effective CO2 capture: Economical CO2 capture demands low-energy separation strategies. We use a liquid-infused surface (LIS) approach to immobilize reactive liquids, such as amines, on a textured and thermally conductive solid substrate with high surface-area to volume ratio (A/V) continuum geometry…. [The technology] shows stable, high capture capacities at power plant CO2 concentrations near flue gas temperatures, preventing energy-intensive temperature swings needed for other approaches.

VC1 Editor’s comment: The science behind this technology appears to be valid, but implementing it will be too costly and engineering intensive for applications other than mitigating already concentrated carbon emissions from power plant flue gases and other large-scale industrial emitters. However, in this application the technology described here would seem to have significant advantages over other proposed technologies.

Wrapping ice and snow to slow/stop melting

William P. Hall on February 13, 2022

Amazing breakthrough technology: cover ice and snow with ‘green’ radiative cooling foil to slow/stop melting and even help freezing

by Jinlei Li et al. 11/02/2022 in Science Advances
Protecting ice from melting under sunlight via radiative cooling: Here, we demonstrate that a hierarchically designed radiative cooling film based on abundant and eco-friendly cellulose acetate molecules versatilely provides effective and passive protection to various forms/scales of ice under sunlight. This work provides inspiration for developing an effective, scalable, and sustainable route for preserving ice and other critical elements of ecosystems.

VC1 Editor’s comment: The cost-effectiveness of this technology remains to be proven in practice. However, the the science appears to be sound, cooling effects of ultra-white paint have been proven in shopping center-scale commercial application, and the acetate film is made from renewable materials and should be safely biodegradable in application.

Global warming sets Australia for worse NB4 bushfires

William P. Hall on February 12, 2022

ANU experts say continuing climate change increases bushfire threats of more than ‘worst case’ scenarios to never before (NB4) seen levels

by Michael Mazengarb 10/02/2022 in Renew Economy
Australia’s bushfire threat already beyond worst-case scenarios, thanks to climate change: Australia will continue to experience more extreme impacts of climate change, with the bushfire threat already exceeding the ‘worst case’ scenarios, experts have told the Australian National University’s 2022 Climate Update event.

What’s in a name? Natural gas is mostly methane!

William P. Hall on February 12, 2022

Marketing gurus know that ‘natural’ is healthy, clean, and good for you. Actually methane is bad and nasty — especially for global warming.

by Rebecca Leber, 10/02/2024 in Vox
The end of natural gas has to start with its name: The oil and gas industry didn’t invent the name. But it invented the myth of a clean fuel.

Water vapor amplifies effects of other greenhouse gases

William P. Hall on February 12, 2022

Ask NASA explains greenhouse gases’ roles & properties. Because water vapor condenses into water, it amplifies warming effects of other gases

by Alan Buis 08/02/2022 in Ask NASA Climate
Steamy Relationships: How Atmospheric Water Vapor Supercharges Earth’s Greenhouse Effect: Some people mistakenly believe water vapor is the main driver of Earth’s current warming. But increased water vapor doesn’t cause human-produced global warming. Instead, it’s a consequence of it. Increased water vapor in the atmosphere supercharges the warming caused by other greenhouse gases.
