The observed and projected rates of increase in freshwater runoff could potentially disrupt ocean circulation if global temperatures rise by 3 to 4 °C over this century as forecast by the IPCC 2001 report.

Shifts in internal temperature variability, measured through SST variance and skewness, are also occurring and contribute to much of the MHW trends observed over the remainder of the global ocean, particularly for MHW duration and intensity.

(1) The warm sea surface temperatures are not just some short - term anomaly but are part of a long - term observed warming trend, in which ocean temperatures off the US east coast are warming faster than global average temperatures.

The diagnostics, which are used to compare model - simulated and observed changes, are often simple temperature indices such as the global mean surface temperature and ocean mean warming (Knutti et al., 2002, 2003) or the differential warming between the SH and NH (together with the global mean; Andronova and Schlesinger, 2001).

Kosaka and Xie made global climate simulations in which they inserted specified observed Pacific Ocean temperatures; they found that the model simulated well the observed global warming slowdown or «hiatus,» although this experiment does not identify the cause of Pacific Ocean temperature trends.

If the observed global trends in temperature rises continue, there will be an increased probability of a recurrence of the phenomenon observed in 1998 on the coral reefs of the Indian Ocean, as well as in other parts of the tropical oceans in coming years.â $?

By comparing modelled and observed changes in such indices, which include the global mean surface temperature, the land - ocean temperature contrast, the temperature contrast between the NH and SH, the mean magnitude of the annual cycle in temperature over land and the mean meridional temperature gradient in the NH mid-latitudes, Braganza et al. (2004) estimate that anthropogenic forcing accounts for almost all of the warming observed between 1946 and 1995 whereas warming between 1896 and 1945 is explained by a combination of anthropogenic and natural forcing and internal variability.

It seemsthe observed increase in trade winds lead to the surfacing of cooler waters in the Eastern Pacific ocean and this phenomenon is found by models to cause global average temperatures to cool.

If the sun is primarily responsible for observed global air temperature changes (even if heavily modulated by ocean behaviour as I contend elsewhere) then we need to know sooner rather than later otherwise a misdiagnosis of the causes of climate change could cause unimaginable disruption and hardship through the imposition of incorrect remedies.

Hocker's Figure 2 shows a comparison of the observed and modeled global ocean temperature anomaly:

A new study of the temporary slowdown in the global average surface temperature warming trend observed between 1998 and 2013 concludes the phenomenon represented a redistribution of energy within the Earth system, with Earth's ocean absorbing the extra heat.

jimmi says: «If the sea surface temperature rise is correctly observed, as the paper assumes, and if it is truly global, as is stated, then a large amount of energy has been added to the top layer of the ocean.»

Steve Fitzpatrick says: «It is an real contribution to link the ENSO to the AMO (this gives the AMO a more solid rational for influencing global temperatures), but it is I think unwise to suggest that ENSO driven cycles are (rather than could possibly be) responsible for most of the observed ocean surface warming since 1900.»

If the sea surface temperature rise is correctly observed, as the paper assumes, and if it is truly global, as is stated, then a large amount of energy has been added to the top layer of the ocean.

It is an real contribution to link the ENSO to the AMO (this gives the AMO a more solid rational for influencing global temperatures), but it is I think unwise to suggest that ENSO driven cycles are (rather than could possibly be) responsible for most of the observed ocean surface warming since 1900.

Global warming is the observed and projected increases in the average temperature of Earth's atmosphere and oceans.

The new research uses multiple runs of a coupled ocean - atmosphere computer model to simulate global temperature changes in response to climate forcing when the sea surface temperature (SST) in the el Niño region follows its historically observed values.

If there is deep - water formation in the final steady state as in the present day, the ocean will eventually warm up fairly uniformly by the amount of the global average surface temperature change (Stouffer and Manabe, 2003), which would result in about 0.5 m of thermal expansion per degree celsius of warming, calculated from observed climatology; the EMICs in Figure 10.34 indicate 0.2 to 0.6 m °C — 1 for their final steady state (year 3000) relative to 2000.

(1) The warm sea surface temperatures are not just some short - term anomaly but are part of a long - term observed warming trend, in which ocean temperatures off the US east coast are warming faster than global average temperatures.

That this is not a reliable way to determine precise global ocean temperatures back to the middle of the 19th Century was observed here; (52)

Craig King - Further to Bob Loblaw's comments; that global surface air temperatures are warming faster than upper ocean temperatures is well - observed and completely uncontroversial.

In a paper, «Heat Capacity, Time Constant, and Sensitivity of Earth's Climate System» soon to be published in the Journal of Geophysical Research (and discussed briefly at RealClimate a few weeks back), Stephen Schwartz of Brookhaven National Laboratory estimates climate sensitivity using observed 20th - century data on ocean heat content and global surface temperature.

As Media Matters has noted, the IPCC's 2007 «Synthesis Report» concluded that» [w] arming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice and rising global average sea level» and that» [m] ost of the observed increase in global average temperatures since the mid-20th century is very likely [defined in the report as a» > 90 %» probability] due to the observed increase in anthropogenic [human - caused] GHG [greenhouse gas] concentrations.»

As Judith says, one of the key conclusions is the paragraph in large red letters «Most of the observed increase in global average temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations... Discernible human influences now extend to other aspects of climate, including ocean warming, continental - average temperatures, temperature extremes and wind patterns (see Figure SPM.4 and Table SPM.2).»

Global sea level is currently rising as a result of both ocean thermal expansion and glacier melt, with each accounting for about half of the observed sea level rise, and each caused by recent increases in global mean temperGlobal sea level is currently rising as a result of both ocean thermal expansion and glacier melt, with each accounting for about half of the observed sea level rise, and each caused by recent increases in global mean temperglobal mean temperature.

The study authors compared the simulations that were correctly synchronized with the ocean cycles (blue data in the left frame below) and the most out - of - sync (grey data in the right frame) to the observed global surface temperature changes (red) for each 15 - year period.

Girma Orssengo rightly demonstrates that one can not determine climate sensitivity empirically from observed changes in CO2 concentration and in global mean surface temperature unless one either studies periods that are multiples of ~ 60 years to cancel the transient effects of the warming and cooling phases of the Pacific and related ocean oscillations or studies periods centered on a phase - transition in the ocean oscillations.

The new finding of the importance of multiple ocean surface temperature changes to the multi-decadal global warming accelerations and slowdowns is supported by a set of computer modeling experiments, in which observed sea surface temperature changes are specified in individual ocean basins, separately.
