The IPCC, an Intergovernmental Panel of Climate Change science experts, has estimated that to just stabilise concentrations at present day levels would require a massive 60 % Value reduction of global carbon dioxide emissions Patient . [ ENCY 0 MCLH 14/03/2014 ]

In the context of future GHG emissions, the time scale of ice loss is competing with the time scale of temperature decline after a reduction of GHG emissions Patient . [ WG1AR5OF 0 ALS 14/03/2014 ]

Some recent studies suggest that the reduction in the aerosol forcing (both anthropogenic and natural) Patient over the Atlantic Location since the 1970s Time may have contributed to the increase in tropical cyclone activity in the region. [ WG1AR5LP 0 MCLH 14/03/2014 ]

Reduction of NOx emissions Patient would also be achieved at cruise altitude, though not necessarily by the same proportion as for LTO. [ 1IPCCAVIATION 0 MCLH 14/03/2014 ]

There is positive RF due to aerosolÐradiation interaction due to reductions in sulfate aerosol Patient . [ WG1AR5HW 0 MCLH 14/03/2014 ]

Some recent studies suggest that the reduction in the aerosol forcing (both anthropogenic and natural) Patient over the Atlantic Location since the 1970s Time may have contributed to the increase in tropical cyclone activity in the region (see Section 14.6.1 for details), and similarly that aerosols may have acted to reduce tropical cyclone activity in the Atlantic in earlier years when aerosol forcing was increasing (Villarini and Vecchi, 2013). [ WG1AR5LP 0 MCLH 14/03/2014 ]

Over tropical forest, reduction of forest coverage Patient would reduce evapotranspiration, also leading to a regional warming. [ WG1AR5MN 0 MCLH 14/03/2014 ]

Reduction in carbon uptake Patient during turn of the century drought in western North America Time . [ WG1AR5NV 0 MCLH 14/03/2014 ]

Some of the first studies (Wu et al., 2010; Cao et al., 2011) showed that the global hydrological cycle could intensify in response to a reduction in atmospheric CO2 concentrations Patient . [ WG1AR5GD 0 MCLH 14/03/2014 ]

The RF from CFCs has declined since 2005 (mainly due to a reduction in the concentrations of CFC-11 and CFC-12) Patient , whereas the RF from HCFCs is still rising (mainly due to HCFC-22). [ WG1AR5SQ 0 MCLH 14/03/2014 ]

CH4 Patient reduction by rice paddy irrigation management, improved fertilizer use, and lower enteric CH4 emissions from ruminant animals Cause ; avoiding anthropogenic agricultural N2O emissions (which for agriculture exceeds carbon emission from fossil fuel use) through the use of slow release fertilizers, organic manure, nitrification inhibitors, and potentially genetically-engineered leguminous plants.

Anthropogenic ocean acidification refers to the component of pH Patient reduction that is caused by human activity Cause . [ WG1AR5CN 0 MCLH 14/03/2014 ]

This is why modeling studies suggest that solar radiation management (geoengineering) methods that maintain a constant surface temperature Cause will lead to a reduction in globally averaged precipitation as well as different regional distributions of precipitation Patient . [ WG1AR5GY 0 MCLH 14/03/2014 ]

Reduction in biogenic calcification Patient due to ocean acidification Cause would weaken the strength of CaCO3 mineral ballasting effect, which could lead organic material to be remineralized at a shallower depth exacerbating the future expansion of shallow hypoxic waters.
