Third, using a «semi-empirical» statistical model calibrated to the relationship between temperature and global sea - level change over the last 2000 years, we find that, in alternative histories in which the 20th century did not exceed the average temperature over 500-1800 CE, global sea - level rise in the 20th century would (with > 95 % probability) have been less than 51 % of its observed value.

So the intensity of radiation (at some frequency and polarization) changes over distance, such that, in the direction the intensity is going, it is always approaching the blackbody value (Planck function) for the local temperature; it approaches this quickly if the absorption cross section density is high; if the cross section density is very high and the temperature doesn't vary much over distance, the intensity may be nearly equal to the Planck function for that location; otherwise its value is a weighted average of the Planck function of local temperature extending back over the path in the direction it came from.

The standstil of global average temperature predicted by the «improved» modell compared to warming predicted from the «old» modell is nothing that happens in the future, it should have happened (but did not happen) in the past, from 1985 to 1999: The «improved» modell (green graph) shows that the global average temperature did not change from 1985 (= mean 1980 - 1990) to 1999 (= mean 1994 to 2004).

You can choose to compare the mean temperature change for 30N and 80N respectively, and you do that by computing the average around the planet — along the circle of constant latitude.

This is clear by your repeated confusion about how taking thousands of temperature measurements to get an average, repeatedly over time, then comparing those averages to identify changes over time, does not yield results measured in integers.

When the IPCC claimed that the GCM models (with GHG forcing included) could replicate the observed changes in global average temperatures do you know if they were referring to a truly global measurement or were they just using the US temp record?

Sorry Pat, I neglected to reply to your question, «Do you consider that an increase in average global temperature of 4 — 8 C would produce «adverse climate change impacts»?

As you can see, over periods of a few decades, modeled internal variability does not cause surface temperatures to change by more than 0.3 °C, and over longer periods, such as the entire 20th Century, its transient warming and cooling influences tend to average out, and internal variability does not cause long - term temperature trends.

Victor also points out that average global surface temperatures doesn't fully represent the changing global climate.

Once such an IPCC exposition of the assumptions, complications and uncertainties of climate models was constructed and made public, it would immediately have to lead, in my view, to more questions from the informed public such as what does calculating a mean global temperature change mean to individuals who have to deal with local conditions and not a global average and what are the assumptions, complications and uncertainties that the models contain when it comes to determining the detrimental and beneficial effects of a «global» warming in localized areas of the globe.

Back in 2009, at the United Nations (UN) Framework Convention on Climate Change, nations around the world drew a hypothetical line in the sand, pledging to do everything in their power to prevent the world annual average temperature from warming an additional two degrees Celsius (3.6 °F)- known as the Copenhagen Accord.

I don't believe climate scientists know any where near as much as they think they do about «global average temperature,» let alone the tenths of a degree change per year they claim to detect.

He did note that the free expansion leaves the average KE per molecule the same — which I know that he knows means that the temperature hasn't changed (although the density certainly has).

As you know, on average CO2 lags temperature change by about 800 years (it varies depending on who does it, the correlation is rather broad and flat, so the number is pretty squirrelly), it is untrue to suggest that natural fluctuations in CO2 always follow temperature fluctuations.

Joshua: If there was no prediction for the first 12 years of the 21rst century, then it seems a bit misleading, in 2012, to say that we do not have a demonstrated record of accuracy for predictions of average temperature change for the 21rst century, or through 2050, or even through 2025.

Still other scientists insist that their data do not show appreciable changes in average temperature anywhere over the course of the interval.

For the latter, one merely has to demonstrate either of two things: that CO2 does not indeed alter the thermal budget of the climate system such that increasing its concentration results in the trapping of more heat within that system, or that the negative feedbacks associated with CO2 - induced warming overwhelm the positive ones and result in a neutral or negative change to the state of the climate's average temperature.

Given that the average global surface temperature has not changed by more than 0.26 °C from one year to the next, I thought that giving him a 0.5 °C margin of error was a generous offer, but alas, McLean did not respond to my offer.

But the true climate change deniers first had their way, doing what is unforgiveable (or even fraudulent) in real science, by retrospectively changing old data until it served their ends, by portraying the Earth as a place of Gaian perfection with only modest diversions from the supposed «average» temperature.

As we discussed in The Day After McLean, average surface temperatures simply don't change from one year to the next by anywhere near the magnitude McLean predicted.

If the different methods are not analysing different definitions then why do values of global average surface temperature (GASTA) from decades ago alter when the method is changed from month to month: which is the right determination any of the ones before a change or any of those after it?

The theory of Anthropogenic Global Warming (aka Human Induced Climate Change) does not fit the following facts: (1) Modern statistical techniques show that there has been no significant change in global average temperature for the last 166 Change) does not fit the following facts: (1) Modern statistical techniques show that there has been no significant change in global average temperature for the last 166 change in global average temperature for the last 166 years.

In other words, regional temperatures change, but the average global temperature doesn't.

While the average earthly temperature does climb in correlation to the amount of atmospheric carbon, people tend to rely on their observations of the weather to validate or repudiate the science behind climate change.

Owing to its amplifying nature, Greenland and the Arctic are reacting stronger to any imposed forcing (has to do with the change in the Hadley circulation which depends on the average temperature).
