Sentences with phrase «stratospheric ozone recovery»

During the period of summer ozone recovery (2000 — 2050), the SAM index exhibits weakly negative, statistically insignificant trends due to stratospheric ozone recovery which offsets the positive forcing imposed by increasing GHG concentrations.

We determine its likely evolution for three intergovernmental panel on climate change (IPCC) special report on emission scenarios (SRES) for austral summer and winter, using a multi-model ensemble of IPCC fourth assessment report models which resolve stratospheric ozone recovery.

We therefore demonstrate that the future SAM will depend both upon GHG emissions and stratospheric ozone recovery.

These NOAA activities constitute a large part of the global scientific effort to understand stratospheric ozone depletion and recovery.

The scientific goal is to determine and interpret trends in global stratospheric ozone, the Antarctic ozone hole, and global atmospheric ozone depleting substances; to investigate these trends for signs of recovery of the ozone layer and evaluate implications for climate change; and to study the efficacy of newly proposed substitutes for currently used ozone - depleting substances.

This will make recovery of the stratospheric ozone layer much slower.

The trend of greater and greater depletion of global stratospheric ozone observed during the 1980s and 1990s is no longer occurring; however, it is not yet clear whether these recent changes are indicative of ozone recovery.
