Typical commercial white paints reject 80%-90% of visible light, but still absorbs ultraviolet light. So it still warms up. Researchers have developed an ultra-white paint which can reject 98% of sunlight, including ultraviolet light. It also releases infrared light, which effectively means the paint can cool itself below surrounding temperatures. The inventors hope it can provide a low-cost, scalable replacement to air conditioning. https://www.purdue.edu/newsroom/releases/2021/Q2/the-whitest-paint-is-here-and-its-the-coolest.-literally..html
Imagine if environmental information was published alongside the quarterly gross domestic product (GDP) figure.Every three months, we would be told that economic growth increased by 0.6 per cent in the last quarter, say, and by 5.9 per cent through the year.But it would also explain we lost another 1,300 koalas last quarter, another 750 hectares of our native forests were logged, and our ocean fish stocks shrank by another 0.5 percentage points. By making the relationship between economic growth and the environment transparent, it might change the national conversation.https://www.abc.net.au/news/2022-12-11/gdp-growth-and-environmental-destruction/101730502
