They also ran atmospheric models that used observed global sea surface temperatures, Arctic sea ice conditions and atmospheric carbon dioxide concentrations in 2010 to assess whether such factors might have contributed to the heat wave.

(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.
They show this with an elegant experiment, in which they «force» their global climate model to follow the observed history of sea surface temperatures in the eastern tropical Pacific.
In particular, would anyone question that the observed trends in sea surface temperature in all basins can be attributed to anthropogenic global warming?
Now that it is possible to simulate the Madden Julian Oscillation (MJO) signal explicitly in global atmospheric models, hypotheses about what controls observed relationships between sea surface temperatures (SSTs) and the MJO can be explored.
Here we show that accounting for recent cooling in the eastern equatorial Pacific reconciles climate simulations and observations.We present a novel method of uncovering mechanisms for global temperature change by prescribing, in addition to radiative forcing, the observed history of sea surface temperature over the central to eastern tropical Pacific in a climate model.
Type 3 dynamic downscaling takes lateral boundary conditions from a global model prediction forced by specified real world surface boundary conditions, such as for seasonal weather predictions based on observed sea surface temperatures, but the initial observed atmospheric conditions in the global model are forgotten.
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.»
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.
Observed changes in (a) global average surface temperature; (b) global average sea level rise from tide gauge (blue) and satellite (red) data and (c) Northern Hemisphere snow cover for March - April.
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.
(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.
In it, they documented how a change in observing practices before and after World War II produced a cold bias in the sea surface temperatures that were incorporated into the compilations of global average temperatures (see here and here for more details).
Note that this result is not directly a test of model fidelity, but rather of linearity; what is converging here is the model's representations of air - sea interaction leading to global mean surface temperature anomalies, not whether the models have the ability to capture the magnitude or even the spatial patterns of observed RASST variability.
Recent studies have found a large, sudden increase in observed tropical cyclone intensities, linked to warming sea surface temperatures that may be associated with global warming (1 - 3).
We present a novel method of uncovering mechanisms for global temperature change by prescribing, in addition to radiative forcing, the observed history of sea surface temperature over the central to eastern tropical Pacific in a climate model.
«Fs», the fixed SST forcing, is a combination of the flux change at the top of (and throughout) the atmosphere and of the global surface air temperature change after the forcing and with observed sea surface temperature (SST) and sea ice (SI) held fixed.
The IPCC has already concluded that it is «virtually certain that human influence has warmed the global climate system» and that it is «extremely likely that more than half of the observed increase in global average surface temperature from 1951 to 2010» is anthropogenic.1 Its new report outlines the future threats of further global warming: increased scarcity of food and fresh water; extreme weather events; rise in sea level; loss of biodiversity; areas becoming uninhabitable; and mass human migration, conflict and violence.
The observed changes (lower panel; Trenberth and Fasullo 2010) show the 12 - month running means of global mean surface temperature anomalies relative to 1901 — 2000 from NOAA [red (thin) and decadal (thick)-RSB- in °C (scale lower left), CO2 concentrations (green) in ppmv from NOAA (scale right), and global sea level adjusted for isostatic rebound from AVISO (blue, along with linear trend of 3.2 mm / year) relative to 1993, scale at left in mm).
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.
