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.

Recent temperature measurements over the past 165 + years based on satellite, marine and land instruments obtained and analyzed by HadCrut, GISS, and Berkeley indicate global temperatures have increased by approximately 1 degree C shown on Figure 7.

With the anthropogenic perturbation likely to be around 2C and maybe more in the next 100 years (that's a global average, it will be much more over northern hemisphere land where we actually live), there are simply no comparable sources of natural variability, and the historical record shows that such temperatures have not been approached in the last 2000 years.

As I said before with exception of GISS, the other four organizations who measure global temperatures [land + ocean] show the same cooling trend from 2002.

«Global surface temperature trends, based on land and marine data, show warming of about 0.8 deg C over the last 100 years.

Global land / ocean temperature records from NOAA, NASA, Berkeley Earth, Hadley / UAE, and Cowtan and Way show no detectable sign of a «pause» in warming through to the present.

Additionally, we show that the largest regional contributor to global temperature trends over the past two decades is land surface temperature in the NH extratropics.

To point out just a couple of things: — oceans warming slower (or cooling slower) than lands on long - time trends is absolutely normal, because water is more difficult both to warm or to cool (I mean, we require both a bigger heat flow and more time); at the contrary, I see as a non-sense theory (made by some serrist, but don't know who) that oceans are storing up heat, and that suddenly they will release such heat as a positive feedback: or the water warms than no heat can be considered ad «stored» (we have no phase change inside oceans, so no latent heat) or oceans begin to release heat but in the same time they have to cool (because they are losing heat); so, I don't feel strange that in last years land temperatures for some series (NCDC and GISS) can be heating up while oceans are slightly cooling, but I feel strange that they are heating up so much to reverse global trend from slightly negative / stable to slightly positive; but, in the end, all this is not an evidence that lands» warming is led by UHI (but, this effect, I would not exclude it from having a small part in temperature trends for some regional area, but just small); both because, as writtend, it is normal to have waters warming slower than lands, and because lands» temperatures are often measured in a not so precise way (despite they continue to give us a global uncertainity in TT values which is barely the instrumental's one)-- but, to point out, HadCRU and MSU of last years (I mean always 2002 - 2006) follow much better waters» temperatures trend; — metropolis and larger cities temperature trends actually show an increase in UHI effect, but I think the sites are few, and the covered area is very small worldwide, so the global effect is very poor (but it still can be sensible for regional effects); but I would not run out a small warming trend for airport measurements due mainly to three things: increasing jet planes traffic, enlarging airports (then more buildings and more asphalt — if you follow motor sports, or simply live in a town / city, you will know how easy they get very warmer than air during day, and how much it can slow night - time cooling) and overall having airports nearer to cities (if not becoming an area inside the city after some decade of hurban growth, e.g. Milan - Linate); — I found no point about UHI in towns and villages; you will tell me they are not large cities; but, in comparison with 20-40-60 years ago when they were «countryside», many small towns and villages have become part of larger hurban areas (at least in Europe and Asia) so examining just larger cities would not be enough in my opinion to get a full view of UHI effect (still remembering that it has a small global effect: we can say many matters are due to UHI instead of GW, maybe even that a small part of measured GW is due to UHI, and that GW measurements are not so precise to make us able to make good analisyses and predictions, but not that GW is due to UHI).

The individual station records (coming soon), show the raw station records (in red), the best estimate of the regional record via kriging in blue, and the global land temperature record in gray for comparison.

According to the Global Land - Ocean Temperature Index graph that you showed above that is not true, perhaps you don't know what «unabated» means?

Figure 2.4 (Folland et al., 2001) shows simulations of global land - surface air temperature anomalies in model runs forced with SST, with and without bias adjustments to the SST data before 1942.

The global SST show mostly similar trends to those of the land - surface air temperature until 1976, but the trend since 1976 is markedly less (Table 2.1).

Now the NOAA data comes in and confirms the GISS data, and shows the http://www.ncdc.noaa.gov/oa/climate/research/2009/jun/global.html Global Highlights: Based on preliminary data, the globally averaged combined land and sea surface temperature was the second warmest on record for June and the January - June year - to - date tied with 2004 as the fifth warmest on record.

Map showing global land and ocean surface temperature departures from average during August 2012.

Translating the above to climate science, if you tell me that in 100 years earth inhabited by your children is going to hell in a handbasket, because our most complicated models built with all those horrendously complicated equestions you can find in math, show that the global temperatures will be 10 deg higher and icecaps will melt, sea will invade land, plant / animal ecosystem will get whacked out of order causing food supply to be badly disrupted, then I, without much climate science expertise, can easily ask you the following questions and scrutinize the results: a) where can I see that your model's futuristic predictions about global temp, icecaps, eco system changes in the past have come true, even for much shorter periods of time, like say 20 years, before I take this for granted and make radical changes in my life?

Earth's global average surface temperature has risen as shown in this plot of combined land and ocean measurements from 1850 to 2012, derived from three independent analyses of the available data sets.

In general, the pattern of change in return values for 20 - year extreme temperature events from an equilibrium simulation for doubled CO2 with a global atmospheric model coupled to a non-dynamic slab ocean shows moderate increases over oceans and larger increases over land masses (Zwiers and Kharin, 1998; Figure 9.29).

Usually scientists rely on the temperature over land, taken from weather stations around the world for the last 150 years, to show global warming.

For example in the technical summary, it says:» The global combined land and ocean temperature data show an increase of about 0.8 °C over the period 1901 — 2010 and about 0.5 °C over the period 1979 — 2010.

Not global surface temperature data, which shows a normal modest decline from the recent El Niño, nor global lower tropospheric temperature data, which shows nothing out of the ordinary, nor land - only surface temperature data, which also shows no large drop.

As a result, only 1 out of 7 Global or Land / Ocean (ie, global less polar regions) temperature indices shows a negative trend over that period (HadCRUT4 -0.002 + / - 0.059 C / deGlobal or Land / Ocean (ie, global less polar regions) temperature indices shows a negative trend over that period (HadCRUT4 -0.002 + / - 0.059 C / deglobal less polar regions) temperature indices shows a negative trend over that period (HadCRUT4 -0.002 + / - 0.059 C / decade).

It shows the global average surface temperature (land and sea) for each decade since 1880, and the dotted line shows what the 30 - year average was from 1961 - 1990.

If global temperatures were being driven by oscillating ocean temperatures then global temperatures would be oscillating and land temperatures would be showing less change than oceans.

I suspect, however, a graph of that might look rather similar to that plot showing global land - ocean temperature increases over time.

Who among hot climatists will want to commit to writing a desire to collaborate in figuring out a way to discredit the more accurate satellite data that shows no global warming going on 2 decades in preference to greater reliance on the use of massaged land - based temperature records that support the global warming alarmists» meme that free enterprise capitalism is destroying the Earth?

That's not what the data shows - Vose et al 2005; «Minimum temperature increased about twice as fast as maximum temperature over global land areas since 1950, resulting in a broad decline in the diurnal temperature range...», and Zhou et al 2009; «Observations show that the surface diurnal temperature range (DTR) has decreased since 1950s over most global land areas...» would disagree.

They used several simple indices, including the land - ocean contrast, the meridional gradient, and the magnitude of the seasonal cycle, to describe global climate variations and showed that for natural variations, they contain information independent of the global mean temperature.

In the case of Hadcrut temperature series they use around 35 - 40 % land data when calculating global data, but GISS have a temperature product using roughly twice this fraction for land area as fig 7 shows.
