- Attribution of observed changes in stratospheric ozone and temperature. Gillett, N. P.; Akiyoshi, H.; Bekki, S.; Eyring, V.; Garcia, R.; McLinden, C. A.; Karpechko, A. Yu.; Plummer, D. A.; Rozanov, E.; Scinocca, J.; Shibata, K. // Atmospheric Chemistry & Physics Discussions;2010, Vol. 10 Issue 7, p17341
Three recently-completed sets of simulations of multiple chemistry-climate models with greenhouse gases only, with all anthropogenic forcings, and with anthropogenic and natural forcings, allow the causes of observed stratospheric changes to be quantitatively assessed using detection and...
- Chemists poke holes in ozone theory. Schiermeier, Quirin // Nature;9/27/2007, Vol. 449 Issue 7161, p382
The article explores on the formation of the ozone holes, how it relates to climatic changes and how chemists are dealing with the problems. It states that the long-lived chloride compounds from the anthropogenic emissions of chlorofluorocarbons are the reasons of the seasonal ozone losses. The...
