estimated before the Industrial Revolution ushered in
wide use of fossil fuels, the EU body said.
Secondly it seems really important to me for the
wider discussion (beyond just the topic of this thread) that some
estimate of the «uncertain» potentiating effect of predicted
temperature increases be provided and integrated with the climate sensitivity predictions so that we can have a statement that actually attempts to predict possible real world
temperature increases.
From the beginning, among other things, I noticed the
wide range of
estimates for the
temperature increase from a doubling of CO2.
The problem is that there's also a lot of extra variability in CET and that the available data is not sufficient for
estimating well enough how much CET can tell about the
wider temperature trends at other times.
It is no surprise there is significant disagreement over the amount of warming
estimated — as James Hansen and the Goddard Institute for Space Studies explain7, there is no clear definition of what we mean by absolute surface air
temperature and
wide variation in the
estimated mean surface
temperature of the planet.
The difference between the dense, small - celled late wood of one season and the
wide - celled early wood of the following spring enables the age of a tree to be
estimated, and the ring widths or density can be related to climate parameters such as
temperature and precipitation.
Millar and Friedlingstein find a transient climate response of 1.84 C / TtC using the Cowtan and Way
temperature record, 2.05 C / TtC using the Berkeley Earth
temperature record, and a median
estimate of 2.11 C / TtC using CMIP5 ESMs (though with a
wide range from 0.8 — 2.5 C / TtC).
Folkerts (Barton Community College); 4.7 ± 0.2; Statistical
Estimates are based on multiple regression of a
wide variety of publicly available monthly arctic data (e.g., extent, area, sea surface
temperature, North Atlantic Oscillation, and so forth).
A methanogenic community composed of both AM and HM taxa will likely respond to
wider temperature ranges and possible substrate changes that occur under climate stress, and both pathways should be considered in C budget
estimates.
If we are trying to
estimate the average
temperature over a
wide area like the U.S. or the Globe, it is advisable to use gridding or some more complicated form of spatial interpolation to assure that our results are representative of the underlying
temperature field.
For ecample Working out historic sea surface
temperatures using one record in a grid cell in a year and spreading that to other grid cells Does not seem to me to be an accurate way of
estimating the
wider temperature.
