A NASA-led study has documented an unprecedented depletion of Earth’s protective ozone layer above the Arctic last winter and spring caused by an unusually prolonged period of extremely low temperatures in the stratosphere. The same ozone-loss processes occur each winter in the Arctic.

Nitrous oxide is a potent greenhouse gas that contributes to climate change and stratospheric ozone destruction. It is produced via a microbial process called denitrification, which converts nitrogen to nitrous oxide and an inert gas called dinitrogen. The findings, the authors hope, will lead to more effective mitigation strategies.

Here, RME show advantages for primary energy and GHG, but disadvantages in terms of acidification, eutrophication and ozone depletion. Increased emissions of GHG may result in particular when production takes place on converted natural land and the associated mobilization of carbon stocks is accounted for, the report finds.

Part of the absorbed energy is converted into infrared radiation that is emitted into the atmosphere and back into space. Most of this infrared radiation passes through the atmosphere, but some is absorbed by GHG molecules like CO 2 , methane, ozone and others. Earlier post.).

Increasing evidence suggests that biomass can be used much more efficiently (and therefore with less environmental impact) through direct combustion to generate electricity and heat, rather than being converted to liquid fuels such as ethanol. However very few studies include water use impacts. while noting that the analysis “.has
