To estimate its evolution during the twenty-first century Patient , two types of prediction must be combined, thus cumulating two types of uncertainty Method :[...] [ JACLET 0 ZJ 10/04/2014 ]

Two different approaches Method exist for estimating the indirect effect of aerosols Patient : empirical methods and mechanistic methods. The former have been applied to estimate the effects of industrial aerosols, while the latter have been applied to estimate the effects of sulphate, fossil fuel carbonaceous aerosols, and biomass aerosols. [ 11IPCCBILAN2001 0 ZJ 10/04/2014 ]

In addition, models for the indirect effect Method have been used to estimate the effects of the initial change in droplet size and concentrations (a first indirect effect), as well as the effects of the subsequent change in precipitation efficiency (a second indirect effect) Patient .

Several approaches Method could be used to estimate the changes in carbon stocks and greenhouse gas emissions of LULUCF projects Patient : (i) estimating carbon stocks and greenhouse gas emissions at a given point in time; (ii) estimating the average changes of carbon stocks or greenhouse gas emissions over time in a project area; [ 14IPCCSRL 0 ZJ 10/04/2014 ]

In this section, information on energy use and CO2 emissions for these sectors Patient has been estimated using an allocation scheme Method and based on a standard electricity conversion factor of 33 % . [ 8IPCCATTENUATION 0 ZJ MCLH 16/06/2014 ]

Radiative forcingof the climate system due to solar irradiance change Patient is estimated tobe 0.3 ± 0.2 Wm?2for the period 1750 to the present (Figure 8) Value , and most of the change is estimated to have occurred during the first half of the 20th century. [ 11IPCCBILAN2001 0 ZJ MCLH 16/06/2014 ]

The methane concentration in 1992 Patient is estimated here Location to be about 2 % less than that in an atmosphere without aircraft Value . [ 1IPCCAVIATION 0 ZJ MCLH 16/06/2014 ]

Natural sources of N2O Patient are estimated to be approximately 10 TgN/yr (1990), with soils being about 65 % of the sources and oceans about 30 % Value . [ 11IPCCBILAN2001 0 ZJ MCLH 16/06/2014 ]

The radiative forcing Patient is estimated at 0.15 Wm?2, which is 6 % of the total from all of the long-lived and globally mixed greenhouse gases (see Figure 9) Value . [ 11IPCCBILAN2001 0 ZJ 10/04/2014 ]

Erosion control practices which include water conservation structures, vegetative strips used as filter strips for riparian zone management, and shelterbelts for wind erosion control can reduce the global quantity of soil organic carbon displaced by soil erosion , which Patient has been estimated to be in the range of 0.5 Gt C yr Value .

Explanation: Microwave satellite data Means have been used since 1979 to estimate temperatures of the lower troposphere between about 8 km altitude and the surface Patient . [ 6CANADAQFP 0 ZJ 10/04/2014 ]

These Guidelines Means were developed to estimate and report national greenhouse gas inventories Patient under the United Nations Framework Conventionon Climate Change (UNFCCC) Criterion , not for the particular needs of the Kyoto Protocol. [ 14IPCCSRL 0 ZJ 10/04/2014 ]

Under these conditions, to estimate the impacts of these modifications on our societies Patient calls for a quite different scientific approach from that which may be used for the assessment of the vulnerability of our economic systems, our landscape, our habitat, and our resources to a climate hazard; the approach used has to be able to confront this vulnerability with ultimately a rather wide range of possible changes.

Through climate change research Method , scientists Agent track the climate, gain insight into how and why it is changing, and estimate future climate Patient . [ 4CANADAFACC 0 ZJ 10/06/2014 ]

The atmospheric model Method is then run for a further 20 years so that researchers Agent can calculate the average flux of energy and fresh water between the atmosphere and the ocean surface and estimate surface winds over the ocean Patient . [ 1CANADAFACC 0 ZJ 10/04/2014 ]
