Sentences with phrase «induced ozone change»

Note that the last remark can go either way, as the solar signal can even be more enhanced at the cost of the sensitivity for the greenhouse signal... And from Hansen ea.: «Solar irradiance change has a strong spectral dependence [Lean, 2000], and resulting climate changes may include indirect effects of induced ozone change [RFCR; Haigh, 1999; Shindell et al., 1999a] and conceivably even cosmic ray effects on clouds [Dickinson, 1975].

Not exact matches

The team's results show that human - induced (anthropogenic) changes in well - mixed greenhouse gases, which are fairly evenly distributed in the atmosphere, and ozone, a greenhouse gas that is found in higher concentrations in the stratosphere, are the primary causes of the approximately 200 - meter rise in the tropopause that has occurred since 1979.

Non-annular atmospheric circulation change induced by stratospheric ozone depletion and its role in the recent increase of Antarctic sea ice extent.

Turner, J. et al (2009) Non-annular atmospheric circulation change induced by stratospheric ozone depletion and its role in the recent increase of Antarctic sea ice extent.

This accessible book presents in clear, jargon - free language the science of global change, including human - induced climate change, the ozone hole, acid rain, and air pollution.

Only when the trends for human - induced heat - trapping gases, sulfur dioxide emissions, soot, ozone, and land use changes are also included do the hindcast model results (Figure 3) and the recorded reality match up.

Changes in the total solar irradiance (TSI) with enhanced extreme ultraviolet (EUV) emission have been hypothesized to induce a dynamic air / ocean circulation response resulting from stratospheric ozone production (Lean & Rind 1998).

This project was the result of the third Ministerial Conference on Environment and Health discussions among European ministers of health and the environment who acknowledged that human - induced changes in the global climate system and in stratospheric ozone pose a range of severe health risks and potentially threaten economic development and social and political stability.

The latter show that human - induced changes in ozone and well - mixed greenhouse gases account for ~ 80 % of the simulated rise in tropopause height over 1979 — 1999.

Changes in stratospheric temperatures, induced by changes in ozone or LLGHG concentration, alter the Brewer - Dobson circulation (Butchart and Scaife, 2001; Butchart et al., 2006), controlling the rate at which long - lived molecules, such as LLGHGs, CFCs, HCFCs and halogens are transported from the troposphere to various levels in the stratoChanges in stratospheric temperatures, induced by changes in ozone or LLGHG concentration, alter the Brewer - Dobson circulation (Butchart and Scaife, 2001; Butchart et al., 2006), controlling the rate at which long - lived molecules, such as LLGHGs, CFCs, HCFCs and halogens are transported from the troposphere to various levels in the stratochanges in ozone or LLGHG concentration, alter the Brewer - Dobson circulation (Butchart and Scaife, 2001; Butchart et al., 2006), controlling the rate at which long - lived molecules, such as LLGHGs, CFCs, HCFCs and halogens are transported from the troposphere to various levels in the stratosphere.

Impacts of methane on agriculture via the induced change in surface ozone are also included.
