The 11 - year (132 - month) running mean temperature (Fig. 3b) shows only a moderate decline of the warming rate.

Finally, the presence of vigorous climate variability presents significant challenges to near - term climate prediction (25, 26), leaving open the possibility of steady or even declining global mean surface temperatures over the next several decades that could present a significant empirical obstacle to the implementation of policies directed at reducing greenhouse gas emissions (27).

It isn't necessarily obvious to the layman that a one - or two - year decline in measured mean surface temperature does not imply that the three - dimensional earth has cooled.

Global mean temperature since the last ice age has oscillated quasi-periodically between about + / - 1 % of its mean; over that time, the mean has slightly declined, as have the maxima and minima of the excursions.

The laws of physics require that continually increasing GHG concentrations will mean a continually increasing temperature (subject to the natural climate fluctuations of course), and that will mean continuing sea ice decline.

For example, Angliss gets into the weeds on the new famous «hide the decline» statement, which Fox News picked up as meaning «hide the decline in all global temperatures».

Northwestern Europe experienced warming, while there was cooling in the south [Central Europe was in between] The average temperature change appears to have declined rapidly with latitude so that essentially no change in mean temperature is reported at low and mid latitudes.

Other Arizona USHCN raw station data is below, showing about equal numbers of stations with declining and increasing maximum mean temperatures over the last 80 years.

I particularly love the irony that the mistaken populist meaning of «Hide the Decline» has accentuated, double underlined so to speak, the current pause in temperature.

«And as for the temperature itself, it is striking, [Gore] made his previous film 10 years ago and — according, again, to the official figures — during this past 10 years, if anything, mean global temperature, average world temperature, has slightly declined.»

What do you think it means to replace the proxy values from 1961 onwards with instrumental temperatures due to the decline?

In this data set» printf, 1,» this «decline» has been artificially removed in an ad - hoc way, and» printf, 1,» this means that data after 1960 no longer represent tree - ring printf, 1,» density variations, but have been modified to look more like the printf, 1,» observed temperatures.»

This means the remaining 60 % increase in CO2 will have to produce a temperature response of 2.6 C, an increase in sensitivity to 4.33 C. Given the exponetially declining effect of ^ CO2 this is contradictory to physical process.

The increase in the airborne fraction as temperatures increase is by no means an established fact; if anything the historical record says the airborne fraction is stable or declining very slightly.

If dynamic forces led to the Arctic sea ice decline and lead to an Arctic sea ice increase, we should expect a reversion to the mean in temperatures (that is, cooling).

Any reduction in global mean near - surface temperature due to a future decline in solar activity is likely to be a small fraction of projected anthropogenic warming.

«Finally, the presence of vigorous climate variability presents significant challenges to near - term climate prediction (25, 26), leaving open the possibility of steady or even declining global mean surface temperatures over the next several decades that could present a significant empirical obstacle to the implemen - tation of policies directed at reducing greenhouse gas emissions (27).

The 12 - month running mean global temperature (Figure 9b) may continue to rise for a few more months before the ENSO change causes the next decline.

«The hemispheric - mean decline in winter ice extent is due in large part to increasing sea - surface temperatures in the Barents Sea and adjoining waters, which are consistent with increased concentrations of greenhouse gases.»

You might very well wonder how it is possible for the mean global surface temperature of the earth in the year 1909 to decline 0.12 °C between May 2008 and January 2014.

But what if The Pause continues into AR6 and beyond, i.e. a flat or declining atmospheric global mean temperature in the face of ever - rising GHG emissions?

«And since it has long been known that the DTR has declined significantly over many parts of the world as mean global air temperature has risen over the past several decades (Easterling et al., 1997), it can be appreciated that the global warming with which this DTR decrease is associated (which is driven by the fact that global warming is predominantly caused by an increase in daily minimum temperature) has likely helped to significantly reduce the CHD mortality of the world's elderly people.»

Rhetorically, unable to rebut the statistics @ 13, he wishes both to distract from the 1910 - 1945 period, to dismiss the relevance of statistics in favour of popular reports and ancedotes (hence the dismissive comment about the «numbers guy»), and (apparently) to assert that the period from 1945 to 1974 consituted not just a pause, as he has previously argued, but an actual decline in global mean surface temperature.

But as the pathbreaking work by Rosamond Naylor and David Battisti has shown, the tropics are already too hot to efficiently grow grain, and those places where grain is produced today are already at optimal growing temperature — which means even a small warming will push them down the slope of declining productivity.

In the Mann version of historic climate there is very limited variation either side of a mean anomaly, which gave rise to a limited MWP, generally substantially cooler than today, with gently declining temperatures throughout the period from 1400 to 1900, coupled with a lesser impact of the «Little Ice Age» than had previously been accepted.

By «actual state of science,» he meant the imploding claims and forecasts made by UN panels and government - funded alarmist «scientists» — many of whom were exposed in the ClimateGate scandal conspiring to «hide the decline» in temperatures, censor climate heretics, and violate Freedom of Information laws.

The model outputs are generally presented as an average of an ensemble of individual runs (and even ensembles of individual runs from multiple models), in order to remove this variability from the overall picture, because among grownups it is understood that 1) the long term trends are what we're interested and 2) the coarseness of our measurements of initial conditions combined with a finite modeled grid size means that models can not predict precisely when and how temps will vary around a trend in the real world (they can, however, by being run many times, give us a good idea of the * magnitude * of that variance, including how many years of flat or declining temperatures we might expect to see pop up from time to time).
