Surface air temperature change relative to 1880 - 1920 in 2055 - 2060 based on climate simulations assuming ice melt increases with a 10 - year doubling time.

Not exact matches

The significant difference between the observed decrease of the CO2 sink estimated by the inversion (0.03 PgC / y per decade) and the expected increase due solely to rising atmospheric CO2 -LRB--0.05 PgC / y per decade) indicates that there has been a relative weakening of the Southern Ocean CO2 sink (0.08 PgC / y per decade) due to changes in other atmospheric forcing (winds, surface air temperature, and water fluxes).

Maps show projected change in average surface air temperature in the later part of this century (2071 - 2099) relative to the later part of the last century (1970 - 1999) under a scenario that assumes substantial reductions in heat trapping gases (B1) and a higher emissions scenario that assumes continued increases in global emissions (A2).

The change in temperature with height of a parcel of air if relative humidity is less than 100 % dT / dz = g / cp Units = ms ^ -2 J ^ -1 kgK = ms ^ -2 kg ^ -1 m ^ -1 s ^ 2m ^ -1 kgK = Km ^ -1 g = gravity 9.81 ms ^ -2 cp = 1004 Jkg ^ -1 K ^ -1

Also Wentz neglects the fact that small changes in relative humidity or difference between surface and near air temperatures can result in large changes in evaporation rates based on their equation (1) which determines evaporation rate.

An independent estimate of global - mean evaporation provides additional support, but critical assumptions on relative humidity and the air - sea temperature difference changes are made that do not have adequate observational basis and are inconsistent with climate models.»

Since this phenomenon first became apparent in the early 1990s, the research community has been seeking to identify and quantify possible sources of errors in the surface and upper air temperature measurements, and it has been trying to understand the physical processes that may have caused surface and upper air temperatures to change relative to one another.

Due to the much higher heat capacity of soil relative to air and the thermal insulation provided by vegetation and surface soil layers, seasonal changes in soil temperature deep in the ground are much less than and lag significantly behind seasonal changes in overlying air temperature.

The map below presents the estimated change in average surface air temperature for 2014 relative to the thirty - year average from 1981 to 2010.

Compilation of Vostok and EPICA Dome C CO2 concentrations (Petit et al., 1999; Siegenthaler et al., 2005) and δD (deuterium isotope record) as a proxy for local air temperature (Petit et al., 1999; Augustin et al., 2004) and the changes in global sea level relative to the present level (Bintanja et al., 2005).

The scatter diagrams described and presented on these pages depict projected changes in seasonal surface air temperature and precipitation for three 30 - year periods (2010 - 2039, 2040 - 2069 and 2070 - 2099) relative to the baseline period 1961 - 1990 in 32 sub-continental scale regions (see below).

Given that > 93 % of warming is going into the oceans, ~ 2.3 % into the atmosphere, even a small rate change in ocean warming relative to the total greenhouse gas imbalance will have a huge effect on air temperatures.

The concentration of H2O is a function of air temperature and while I'm sure it would be nice to have a relative humidity proxy, because water vapor is a response not a forcing of climate change, we are not losing evidence of cause of change.

Much more energy is transferred via the processes of evaporation / condensation and freeze / sublimation at relative constant air temperature than can be accounted for by changes in air temperature.
