Climate change to produce more rainbows

Rainbows are produced when water droplets refract sunlight. Sunlight and rainfall are therefore essential ingredients for rainbows. Human activities such as burning fossil fuels are warming the atmosphere, which changes patterns and amounts of rainfall and cloud cover. “Living in Hawai’i, I felt grateful that stunning, ephemeral rainbows were a part of my daily life,” …

Passenger car preheating produces as much particulate emissions as driving dozens of kilometers

Publishing their findings in Atmospheric Environment: X, the researchers measured auxiliary heater (AH) particulate emissions from the preheating of three gasoline, and three diesel cars for a half an hour period. Preheating was carried out outdoors in sub-zero conditions, i.e., when preheating is recommended by the AH manufacturer. In terms of particulate emissions, using an …

‘Forever chemicals’ persist through wastewater treatment, may enter crops

PFAS, often referred to as “forever chemicals,” are used to make fluoropolymer coatings and products that resist heat, oil, stains, grease and water, and are found in a variety of products from clothing and furniture to food packaging and non-stick cooking surfaces. “PFAS are so pervasive and persistent that they have been found in the …

Global collaboration saved countries $67 billion in solar panel production costs

Now, a new study published in the journal Nature has calculated that the globalized supply chain saved countries $67 billion in solar panel production costs. The study also found that if strong nationalistic policies that limit the free flow of goods, talent and capital are implemented going forward, solar panel costs will be much higher …
