How Engineers Can Help Protect Earth From Worsening Climate Change

Cars That Think

Fortunately, we still have a narrow window of opportunity to alter the Earth’s climate path, and I believe we can do it. Climate change is a global societal crisis that is causing devastating consequences. Deforestation is contributing to climate change. IoT food container tags can reduce food and water waste.

Pilot Project Sends Kelp–and Carbon–to the Seafloor

Cars That Think

Last January, in the waters off Cebu City in the Philippines, researchers first deployed a huge flexible ring seeded with seaweed and spanned by spokelike ropes and tubes. Every nightfall, cranks mounted on a floating platform lower the ring 25 meters below the surface to expose the seaweed to cooler, more nutrient-rich water.

Perspective: The Role of Offsets in Climate Change Legislation

Green Car Congress

This article shows that including offsets in climate change legislation would likely make an emissions program more cost-effective by: (a) providing an incentive for non-regulated sources to generate emission reductions; and (b) expanding emission compliance opportunities for regulated entities. 3) Measurement.

Researchers demonstrate electrochemical synthesis of ammonia from air and water under mild conditions

Green Car Congress

is well known that some higher plants can synthesize ammonia or its derivatives directly from air and water at room temperature. To the best of our knowledge, there is no report on artificial synthesis of ammonia direct from air and water. Scientific Reports 3, Article number: 1145 doi: 10.1038/srep01145. —Lan et al.

UMD-led study: road salts and other human sources are threatening world’s freshwater supplies

Green Car Congress

Kaushal and his team named these cascading effects of introduced salts Freshwater Salinization Syndrome, and it can poison drinking water and cause negative effects on human health, agriculture, infrastructure, wildlife and the stability of ecosystems. In the built environment, salts can degrade roadways and infrastructure.

This article is part of our exclusive IEEE Journal Watch series in partnership with IEEE Xplore. This information could, for example, make it simpler for plant phenotyping researchers to compare how different plants respond to water shortages, helping those researchers develop drought-tolerant crops.
