Fish-eating species like cormorants below - typically have small, undifferentiated tongue because fish are often swallowed whole The tongues of cormorants and other fish-eating species are small because these species swallow prey whole and tongues are not needed to manipulate or position food in the oral cavity. Dorsal view of the surface of the lower bill of a Great Cormorant Phalacrocorax carbo. Arrow shows the tongue with sharpened tip.

Temporal stability of global air temperature estimates It is interesting to compare the various global air temperature estimates as to their internal degree of stability for the whole temperature record as such. Especially for surface air temperature estimates, a certain degree of change over time affecting especially the last few months is to be expected, as additional station data may be reported and incorporated in the database.

But for the older part of the temperature record numerical stability over time would be expected, provided that the mathematical procedure used for estimating the global temperature is considered mature by the research team preparing the data series considered.

In this context, maturity would imply that, for example, the November temperature reported by a certain database in February would be identical to the November value reported previously by the same database. Below a series of diagrams is shown to illustrate the degree of maturity, calculated for various databases by plotting the net change in their global temperature record since May or February May or February has been chosen as start date for this test as this represents the oldest version of the individual temperature records available to the webmaster.

All diagrams below are using the same temperature scale, to enable easy visual comparison. A fine study of temporal instability can be inspected here in Norwegian. This temperature estimate extends back to December Click here for explanation of temporal stability.

Click here to see a graph showing the most recent version of the HadCRUT3 and 4 global temperature estimate. Previous to the version change 3 to 4 Octoberthe HadCRUT temperature record showed a high degree of temporal stability.

Another version change was made on October 2, Click here for an explanation of temporal stability. Click here to download the series of estimated HadCRUT4 global monthly surface air temperature anomalies since Click here or here to download the series of estimated HadCRUT3 global monthly surface air temperature anomalies since Click here to download the February version of estimated HadCRUT3 global monthly surface air temperature anomalies since It is interesting to note that the overall net adjustment shown by the HadCRUT surface temperature record since February see figure above is that of more or less equal warming for the entire record since This is in contrast to the net adjustment of the two other surface records, NCDC and GISSwhich both display a net cooling adjustment beforeand a net warming adjustment for the more recent part of the record, resulting in an overall increasing temperature increase since One of the most important effects of the version change is a reduction of the post cooling.

In Genesis, the serpent is the enemy of Adam, trying to trick him out of the chance to understand good and evil by developing a moral sense and thus becoming fully human.

- Comparing Sources of Research Material The purpose of the assignment is to compare and contrast the source of research material available to a learner. We were first assigned to find a source from the Internet, and the second assignment was to find another source from the periodicals in the USCA library.

°C/kW is technically a measure of the thermal resistance of my home’s building envelope.
