Less air pollution leads to higher crop yields, says study

Envirotec Magazine

The analysis, published on 1 June in Science Advances , uses satellite images to reveal for the first time how nitrogen oxides – gases found in car exhaust and industrial emissions – affect crop productivity. Overall, the effects seemed most negative in seasons and locations where NOx likely drives ozone formation.

This year’s ozone hole could be the smallest it has been in 30 years

AGreenLiving

For decades, scientists have closely observed the ozone layer , which protects Earth from the sun’s harmful ultraviolet (UV) radiation. Ozone is created in our atmosphere when the sun’s high-energy UV rays rupture the stable covalent bonds of atmospheric oxygen (O2) molecules, transforming them into free radicals.

It’s packed with energy; per unit of weight, at least 60 times as much as the lithium-ion batteries used to propel electric cars. In the presence of the sun’s rays, nitrogen molecules set of a chain of reactions that produce ozone and destroy free-floating atmospheric methane. It’s also terrible for the climate.
