Sentences with phrase «warming bias»

The term "warming bias" refers to a tendency or inclination to overestimate or emphasize the increase in temperature. In other words, it means focusing on or presenting information that supports the idea of rising temperatures, while overlooking or downplaying factors that might suggest otherwise. Full definition
Surface - based temperature histories of the globe contain a significant warming bias due to the urban heat island effect.
They display a global warming bias throughout — bolstered by temperature data contaminated by «urban heat island» effects, due to measuring stations being located too close to human heat sources.
A related criticism is that the decline in used station count has disproportionately removed stations from colder climates and thus introduced a false warming bias to the record.
It adds a remarkably large and growing warming bias to the record beginning in about 1920.
This particular type error must, to the extent it occur, introduce an exclusively warming bias to the affected data.
This is the normal expected adjustment, because it would remove urban warming bias.
No single temperature record exhibits a significant or consistent warming bias relative to the others.
Well, the only possible reason would be if there was some kind of warming bias in 1940 in Wellington that did not exist in 1980.
For example, many of the Arctic stations are airport stations, and improvements in the airport infrastructure, such as insulation of permafrost - based runways (e.g., Instanes & Mjureke, 2005) could easily have introduced warming biases in recent decades.
As a result of this extra urban warmth, if a weather station becomes urbanized, this introduces an artificial warming bias into the station's record, i.e., urbanization bias.
That is, gradual urbanization has introduced an artificial warming bias into their weather records.
Compared to nearby ground - level instruments and nearby airports and surrounding COOPs, it is clear that a strong warm bias exists, partially because of the rooftop location.
So, we can see that both the Unadjusted and the Partially adjusted datasets show a substantial warming bias due to poor station sitings.
However, in this study, these contradictions are resolved, and it is shown that poor station quality has introduced a noticeable warming bias into temperature trend estimates for the U.S.
Correcting this error did not bring the early thermometers completely in line with proxies — up to 0.9 F of additional warm bias might still persist from other sources, such as differences in the thermometers or in how people read them — «but I think we are nearer to the truth,» said Böhm in 2012.
In contrast CO2 global warming advocates used spurious correlations, opportunistic models and the current global warming bias as a few adamant players including the IPCC, the journal Nature and Michael Mann repeatedly trumpeted a climate causation.
When a sample of highly urbanized stations was tested, the adjustments successfully removed warming bias for the 1895 - 1980 period, but left the 1980s - 2000s period effectively unadjusted.
As just one example of the issues, we have identified a significant warm bias in the observed analysis; see
The bias is larger (∼ 4 K) in regions where the primar y source of data is buoys, which contain warm biases in winter owing to the insulation effect of snow covering the sensors.
And adjusting older temepratures down means that in the more rural society of 50 years ago we had more warming biases than we have today.
Therefore is one is using nighttime temperatures to calculate the mean temperature there is about a 0.03 / decade warming bias.
The climate models analyzed in the paper «Causes of model dry and warm bias over central U.S. and impact on climate projections,» included a precipitation deficit that is associated with widespread failure of the models in capturing actual strong rainfall events in summer over the region.
He then goes on to complain that the mainstream media has not yet covered his «clearly documented warm bias», and uses it as an example of how most journalists don't cover any perspectives that deviates from the IPCC.
Looking at the adjustments, it seemed odd that they implied improving station location quality and reduced warming bias in the measurements, despite Anthony Watts work calling both assumptions into question.
I would trust their records FAR more so than the adjusted and extremely warm biased garbage created out of thin air by the agenda and money driven «climate scientists» of today.
But, the development of the urban heat island would have also introduced a gradual warming bias into the NWS weather record.
This introduces a significant non-climatic warming bias into long - term records.
Both series show a weak warm bias around 1998 followed by a rapid transition to a strong cool bias driven by the missing data from both poles.
Chief Hydrologist, you seem unaware that the obsolete Wong and Willis data that you are relying on was erroneous and it was Willis himself who discovered that the apparent ocean cooling was caused by some very faulty ARGO floats and a residual warm bias in XBT data.
The Hadcrut4 adjustment in any event seems to have made an error in their adjustments whilst taking account of the engine room warming bias, they have wholly ignored the fact that ships do mot draw SST but draw sea water from depth often in the region of 7 to 10m, and this means that the source of the water being sampled is cooler than SST.
