And, this result was nearly always accomplished by each entity systematically removing the previously existing
cyclical temperature pattern.
There may well be a
long cyclical temperature variation, like the shorter term ones we can see in our relatively short term global temperature record..
The North Atlantic Oscillation and Atlantic Multidecadal Oscillation's influences on warm ocean currents explain both Greenland's
cyclical temperature behavior and current glacial retreat.
The Second Supplement to Petition states: Adjustments that impart an ever - steeper upward trend in the data by removing the
natural cyclical temperature patterns present in the data deprive the GAST products from NOAA, NASA and Hadley CRU of the credibility required for policymaking or climate modeling, particularly when they are relied on to drive trillions of dollars in expenditures.
Some evidence suggests that
the cyclical temperature increase associated with El Niño currents increases the likelihood of such outbreaks, by increasing the ability of the bacterium to reproduce in polluted waters.
There is something to be said also for man's activities, but also for
the cyclical temperature changes on our planet.
You can try and guesstimate
the cyclical temperature swings, resulting from oceans moving heat around and thermalizing it.
But in each case
those cyclical temperature trends were homogenized to look like the linear urbanized trend at Marysville.
Similarly, the raw data for other well - sited rural stations like the Cuyamaca in southern California also exhibited
the cyclical temperatures predicted by the PDO (see lower panel).
In fact, the report says, «the magnitude of their historical data adjustments, that removed
their cyclical temperature patterns, are totally inconsistent with published and credible U.S. and other temperature data.
