Sentences with phrase «first estimate of the global temperature»
Our first estimate of global temperature for the remainder of the Cenozoic assumes that ΔTs = ΔTdo prior to 5.33 Myr BP, i.e. prior to the Plio - Pleistocene, which yields a peak Ts of approximately 28 °C at 50 Myr BP (figure 4).

«It's the first time that a scientific study compared different methods of estimating temperature impacts on global crop production.
The concatenation of modern and instrumental records [52] is based on an estimate that global temperature in the first decade of the 21st century (+0.8 °C relative to 1880 — 1920) exceeded the Holocene mean by 0.25 ± 0.25 °C.
First, it provides a compilation of global trends in glacier terminus positions since 1600 A.D. Second, it uses this compilation to create a new estimate of global temperature change.
In addition to a discussion of some of the extreme events of 2011 this also comes with a first estimate of the 2011 global temperature, see their graph below:
Jim's and the British group are the longest standing of the three, having both published their first global temperature estimates in 1981.
The concatenation of modern and instrumental records [52] is based on an estimate that global temperature in the first decade of the 21st century (+0.8 °C relative to 1880 — 1920) exceeded the Holocene mean by 0.25 ± 0.25 °C.
Despite the stability of those ice sheets in the Holocene, there is evidence that sea level was much more variable during the Eemian, when we estimate the peak global temperature was only +1.0 °C warmer than in the first decade of the twenty - first century.
We obtain an absolute temperature scale using the Jones et al. [69] estimate of 14 °C as the global mean surface temperature for 1961 — 1990, which corresponds to approximately 13.9 °C for the 1951 — 1980 base period that we normally use [70] and approximately 14.4 °C for the first decade of the twenty - first century.
As the first figure above shows, the IPCC estimates the temperature influence of internal variability since 1950 at ± 0.1 °C, during which time we've seen about 0.65 °C global surface warming.
Well, I estimated the first derivative of global mean surface temperature using a Bayesian state model, and I got something around 0.01 degrees Celsius per year increase (see here and here), which is consistent with the Cowtan and Way estimate.
In the first IPCC report there was a graph of estimated global temperatures for the last two centuries.
He did do the first quantitative outlook of the effects of CO2 changes on global temperature (of which he got very lucky in being close to modern estimates), but his target was largely to examine the coming and going of ice ages.
