Sentences with phrase «lacking global observations»

However, lacking global observations of surface mass and ocean heat content capable of resolving year to year variations with sufficient accuracy, comprehensive diagnosis of the events early in the altimetry record (e.g. such as determining the relative roles of thermal expansion versus mass changes) has remained elusive.

Trenberth says that the climate monitoring principles set by the Global Climate Observing System (GCOS), the lead international organization for oversight of systematic climate observations, lack provisions for verifying accuracy and confirming or refuting «surprising» climate - change results based on satellite data.

«It has been claimed that the early - 2000s global warming slowdown or hiatus, characterized by a reduced rate of global surface warming, has been overstated, lacks sound scientific basis, or is unsupported by observations.

This criterion may not be satisfied if observations are available only over a short time period (as is the case for the vertical structure of clouds), or if the predictor is defined through low - frequency variability (trends, decadal variability), or if there is a lack of consistency among available datasets (as in the case for global - mean precipitation and surface fluxes).

«The authors write that North Pacific Decadal Variability (NPDV) «is a key component in predictability studies of both regional and global climate change,»... they emphasize that given the links between both the PDO and the NPGO with global climate, the accurate characterization and the degree of predictability of these two modes in coupled climate models is an important «open question in climate dynamics» that needs to be addressed... report that model - derived «temporal and spatial statistics of the North Pacific Ocean modes exhibit significant discrepancies from observations in their twentieth - century climate... conclude that «for implications on future climate change, the coupled climate models show no consensus on projected future changes in frequency of either the first or second leading pattern of North Pacific SST anomalies,» and they say that «the lack of a consensus in changes in either mode also affects confidence in projected changes in the overlying atmospheric circulation.»»

The growing divergence between models and observations even on a global average, and the lack of mathematical foundation to the statement that the fluctuations between runs of the same models and between runs of different models «are noise» [73] forbids their use as justification of economic or political decisions.

The growing divergence between models and observations even on a global average, and the lack of mathematical foundation to the statement that the fluctuations between runs of the same models and between runs of different models «are noise» [Monckton, 29 July 2014] forbids their use as justification of economic or political decisions.

There is a lack of knowledge of natural GIS variability, and Greenland temperature changes have differed from the global trend (26), so interpretation of recent observations remains uncertain.

the current assessment concludes that there is not enough evidence at present to suggest more than low confidence in a global - scale observed trend in drought or dryness (lack of rainfall) since the middle of the 20th century, owing to lack of direct observations, geographical inconsistencies in the trends, and dependencies of inferred trends on the index choice.

The lack of an oscillatory model signal suggests that the inter-decadal global mean surface temperature signal derived from the observations and shown in Figs. 1A and 2B is indeed the signature of natural long - term climate variability.

I suspect that none will take on this challenge: (a) You are not a PHOSTA and lack the background, knowledge and critical thinking skills it takes to understand the existing data and its implication in terms global geochemical systems; (b) You will be unable to find through literature research or create via experiment or observation the data needed to come to a self - consistent derivation and will thus ignore this challenge in the face of embarrassment; or (c) You will want to conveniently ignore the myriad of data presented by Bohm and others since these data contradict your theory and your working studiously to prove otherwise is, well, just inconvenient.

What is lacking are a) a statistically robust correlation between atmospheric CO2 and global temperature (original topic of this thread) and b) empirical data based on physical observations to support the AGW premise.
