These uncertainties make it difficult to determine whether models still have common, fundamental errors in their representation of the vertical structure
of atmospheric temperature change.
(6) It is not currently possible to determine whether or not there exists a fundamental discrepancy between modeled and
observed atmospheric temperature changes since the advent of satellite data in 1979.
Despite such agreement in the large - scale features of model and observed geographical patterns
of atmospheric temperature change, most models do not replicate the size of the observed changes.
«Over the full 420 ka of the Vostok record, CO2 variations lag behind
atmospheric temperature changes in the Southern Hemisphere by 1.3 + / - 1.0 ka, and lead over global ice - volume variations by 2.7 + / - 1.3 ka.»
Newly published research in «PNAS» identifies what authors call a «vertical human fingerprint» in satellite - based estimates
of atmospheric temperature changes, adding still more to confidence levels about human influences in warming.
A number of recent studies have used instrumental records of surface, ocean and
atmospheric temperature changes to estimate climate sensitivity.
Temperature measurements retrieved from the hundreds of balloon - borne radiosonde instruments that are released each day by the various national weather services provide much more detailed information on the vertical structure of
atmospheric temperature changes than is available from satellites.
In
atmospheric temperature changes — where satellite instruments are much to be preferred.
El Niño event,
the atmospheric temperature change has been a paltry +0.1 °C per century trend - essentially, global warming has been non-existent.
Despite massive amounts of CO2 emissions since the super El Niño event,
the atmospheric temperature change has been a paltry +0.1 °C per century trend - essentially, global warming has been non-existent.
