Sentences with phrase «c upper temperature»

The EU's support for a 1.5 C upper temperature rise limit is disingenuous when it is not committing to more action.

Not exact matches

In some rough order of certainty we can consider that the 11 year solar cycle impacts on the following are well accepted: stratospheric ozone, cosmogenic isotope production, upper atmospheric geopotential heights, stratospheric temperatures and (slightly less certain and with small magnitudes ~ 0.1 deg C) tropospheric and ocean temperatures.
If industry - generated aerosols have a more limited cooling effect than originally thought, we can clean up and scale down dirty coal plants without worrying too much about consequent sudden jumps in global temperatures of up to 2 degrees C (if I remember the upper limits of earlier studies correctly).
Unless upper troposphere are over Antarctica falls to temperatures approximately 6.5 o C per km of altitude above the surface, it can not fall, with the consequence that pressure will build up at altitude stopping further circulation.
(c) The global mean (80 ° N to 80 ° S) radiative signature of upper - tropospheric moistening is given by monthly time series of combinations of satellite brightness temperature anomalies (°C), relative to the period 1982 to 2004, with the dashed line showing the linear trend of the key brightness temperature in °C per decade.
Totals is dominated by those over 60y with the share of 86 %) Page 6: Dependence on temperature (optimal temperature in Finland 14C, Italy 20.22 C, Taiwan 30 - 32C Page 7: Coronary artery disease Page 8: Influenza (upper), high temperatures of 1972 and 1988 (lower)
(See article on unforseeability) Although even more optimistic predictions of climate change impacts are disastrous for some of the world's most vulnerable people, the upper end of possible human - induced temperature increases in this Century of 5 to 9 o C will be catastrophic and perhaps unimaginable for the world.
(Fingerprint studies draw conclusions about human causation that can be deduced from: (a) how the Earth warms in the upper and lower atmosphere, (b) warming in the oceans, (c) night - time vs day - time temperature increases, (d) energy escaping from the upper atmosphere versus energy trapped, (e) isotopes of CO2 in the atmosphere and coral that distinguish fossil CO2 from non-fossil CO2, (f) the height of the boundary between the lower and upper atmosphere, and (g) atmospheric oxygen levels decrease as CO2 levels increase.
NOAA better describes the data as the «average temperature in the upper 300 meters, deg C».
It is not «conduction» but exchange of radiation; if you keep your hands parallel at a distance of some cm the right hand does not (radiatively) «warm» the left hand or vice versa albeit at 33 °C skin temperature they exchange some hundreds of W / m ² (about 500 W / m ²) The solar radiation reaching the surface (for 71 % of the surface, the oceans) is lost by evaporation (or evapotranspiration of the vegetation), plus some convection (20 W / ²) and some radiation reaching the cosmos directly through the window 8µm to 12 µm (about 20 W / m ² «global» average); only the radiative heat flow surface to air (absorbed by the air) is negligible (plus or minus); the non radiative (latent heat, sensible heat) are transferred for surface to air and compensate for a part of the heat lost to the cosmos by the upper layer of the water vapour displayed on figure 6 - C.
Over the same period of time as the upper ocean is supposed to have warmed by some 0.05 C (according to ARGO), the sea surface temperature (HADSST2) has cooled by 0.063 C.
Therefore, I find it hard to see how a * living * upper treeline of very old trees can measure any temperature changes over their age greater than 1.2 C (ok, make it 1.5 C at most with unsaturated air).
So this looks like pretty simple math: 150 meters X 0.8 C / 100m = 1.2 C is the approximate temperature change that can be registered by the upper treeline (since at 150 meters below, where it is 1.2 C warmer, the trees don't respond to the temperature surge with a growth surge).
In Jones et al 1990 it is reported that data for the US showed an urban influence of 0.15 C over the period 1901 - 1984 and that «The results for the United States clearly represent an upper limit to the urban influence on hemispheric temperature trends.»
Not to mention that CO2 and N2O also covary with methane, so even if the entire temperature change was based on GHG changes and not orbital changes, CH4 would contribute less than half... My back of the envelope calculations suggests a forcing change of less than 0.2 W / m2 from a drop of 245 ppb — even at the upper end of the CS range this would contribute only about half a degree C to cooling...
