The warming effect of emissions complicates this cycle, so modelling the overall effect is fraught with uncertainty.

«While there is some uncertainty regarding the size, position and timing of this year's hypoxic zone in the Gulf, the forecast models are in overall agreement that hypoxia will be larger than we have typically seen in recent years.»

This greatly reduces the uncertainty in the overall radiosonde mean, and implies that the model uncertainty dominates in the calculation of (sigma - means).

Cloud responses are more uncertain and that feeds in to the uncertainty in overall climate sensitivity — but the range in the AR4 models (2.1 to 4.5 deg C for 2xCO2) can't yet be constrained by paleo - climate results which have their own uncertainties.

After establishing sources of uncertainty and methods for code verification, the paper looks at a representative sampling of verification and validation efforts that are underway in the glacier modeling community, and establishes a context for these within an overall solution quality assessment.

In the second part, the downscaling methods were used to make projections of future climate extremes, which were then examined for consistency and to determine the contribution of individual factors, such as choice of downscaling method and climate model, to the overall uncertainty.

This general approach has been used before, for other aspects of climate system models, and has often significantly reduced overall uncertainty.

Two other important records from satellite instruments — one from MODIS and the other from MISR — don't agree well over land, so scientists hope that data from other other sensors like SeaWiFS might help resolve some of the discrepancies and reduce the overall uncertainty about aerosols in climate models.
