Sentences with phrase «mean global land surface temperatures»

The challenge will be settled using the NASA GISS mean global land surface temperatures for the conventional climate averaging period (defined by the World Meteorological Organization as 30 years) ending on December 31, 2016.

Antartica would contribute a bit under 9.5 % of the mean global land surface temperature and a bit under 2.8 % of the mean global surface temperature, if I have got my data right.

Not exact matches

Global mean temperatures averaged over land and ocean surfaces, from three different estimates, each of which has been independently adjusted for various homogeneity issues, are consistent within uncertainty estimates over the period 1901 to 2005 and show similar rates of increase in recent decades.

Ray, I think Lee Grable's point is important: The fact that we use the term «global temperature» to mean the average temperature on a two - dimensional surface rather than the three - dimensional ocean plus land plus atmosphere system of the earth has the potential to allow confusion.

Overall, ecosystem - driven changes in chemistry induced climate feedbacks that increased global mean annual land surface temperatures by 1.4 and 2.7 K for the 2 × and 4 × CO2 Eocene simulations, respectively, and 2.2 K for the Cretaceous (Fig. 3 E and F).

Lou Grinzo (12)-- I am under the impression that HadCRUTv3 uses air temperatures on land and sea surface temperatures in the oceans to produce their global mean.

However, the CRU global mean combined land air / sea surface temperature estimates for Jan - Aug 2005 lag behind the 1998 annual mean estimate by 0.08 C (0.50 C vs. 58C for 1998) while GISS indicates a lag of 0.02 C.

«The average global temperature anomaly for combined land and ocean surfaces for July (based on preliminary data) was 1.1 degrees F (0.6 degrees C) above the 1880 - 2004 long - term mean.

By comparing modelled and observed changes in such indices, which include the global mean surface temperature, the land - ocean temperature contrast, the temperature contrast between the NH and SH, the mean magnitude of the annual cycle in temperature over land and the mean meridional temperature gradient in the NH mid-latitudes, Braganza et al. (2004) estimate that anthropogenic forcing accounts for almost all of the warming observed between 1946 and 1995 whereas warming between 1896 and 1945 is explained by a combination of anthropogenic and natural forcing and internal variability.

Since then there are a number of papers published on why the warming was statistically insignificant including a recent one by Richardson et al. 2016 which tries to explain that the models were projecting a global tas (temperature air surface) but the actual observations are a combination of tas (land) and SST oceans, meaning projected warming shouldn't be as much as projected.

Many agricultural regions warm at a rate that is faster than the global mean surface temperature (including oceans) but slower than the mean land surface temperature, leading to regional warming that exceeds 0.5 °C between the +1.5 and +2.0 °C Worlds.

Monthly averages of global mean surface temperature (GMST) include natural variability, and they are influenced by the differing heat capacities of the oceans and land masses.

The evolution of global mean surface temperatures, zonal means and fields of sea surface temperatures, land surface temperatures, precipitation, outgoing longwave radiation, vertically integrated diabatic heating and divergence of atmospheric energy transports, and ocean heat content in the Pacific is documented using correlation and regression analysis.

The fact this is seemingly not fully recognized — or here integrated — by Curry goes to the same reason Curry does not recognize why the so called «pause» is a fiction, why the «slowing» of the «rate» of increase in average ambient global land and ocean surface air temperatures over a shorter term period from the larger spike beyond the longer term mean of the 90s is also meaningless in terms of the basic issue, and why the average ambient increase in global air temperatures over such a short term is by far the least important empirical indicia of the issue.

What contribution to the overall mean global surface temperature do the land based and SSTs make.

To facilitate comparison across simulations using all GCMs and RCPs, we express global vegetation change with respect to change in global mean land surface temperature (ΔMLT).

Global temperatures usually are described in terms of the surface air temperature anomaly, the deviation of the temperature at each site from a mean of many years that is averaged over the whole world, both land and oceans.

(It is frequently forgotten or overlooked in discussions of global mean temperature that temperatures over land rise much more than temperatures over ocean — and ocean, of course, occupies roughly 70 % of the world's surface.
