Sentences with phrase «trends in thermometer»

We conclude that the fact that trends in thermometer - estimated surface warming over land areas have been larger than trends in the lower troposphere estimated from satellites and radiosondes is most parsimoniously explained by the first possible explanation offered by Santer et al. [2005].

Not exact matches

Running on two AAA batteries, the thermometer keeps its last 20 readings stored in its memory so you can keep track of trends over time.

When they corrected the error, Wentz and Schabel derived a warming trend of about 0.07 °C per decade, more in line with surface thermometers and climate models.

The warming trend is the same in rural and urban areas, measured by thermometers and satellites, and by natural thermometers.

The same issues have dogged other attempts by climate scientists to glean clues on climate trends from bodies of data collected by satellites and weather balloons for other reasons (not to mention ongoing attempts to discern climate patterns in tree rings, ice layers, and other natural substitutes for thermometers; remember the «hockey stick» debate?).

SW fails to mention effects that may counter-act warming trends, such as irrigation, better shielding of the thermometers, and increased aerosol loadings, in addition to forgetting the fact that forests were cut down on a large scale in both Europe and North America in the earlier centuries.

Alternatively, Mann should have confronted the divergence problem head on, and shown how the trend in the adjustments to the thermometer record had brought about the divergence.

Global temperatures are a real mish mash and it woud be interesting to judge your comment against real life single series temperatures to see if it stands up, whereby it can be seen that some areas of the world have not followed the warming trend but their cooling signal has been smothered by a warming one, probably from the thermometers placed in newly urbanised areas.

Using a record ending in 1995, Wentz showed a slight warming trend of 0.07 ⁰ C / decade, about half of what was being observed by surface thermometers.

MM04 failed to acknowledge other independent data supporting the instrumental thermometer - based land surface temperature observations, such as satellite - derived temperature trend estimates over land areas in the Northern Hemisphere (Intergovernmental Intergovernmental Panel on Climate Change, Third Assessment Report, Chapter 2, Box 2.1, p. 106) that can not conceivably be subject to the non-climatic sources of bias considered by them.

The Surface Stations project has revealed that many of the thermometer shelters used for calculating temperature trends are currently located near artificial heating sources, such as the ones in the Marysville, California station shown above (the thermometer is at the point labelled MMTS Shelter).

Homewood found that all three operational rural thermometers in Paraguay had been adjusted by NASA to show a warming trend where one did not exist before.

What they found was that the tree rings showed a downward trend in temperatures starting at this time while the actual thermometer readings showed a temperature increase.

See, the first thing to do is do determine what the temperature trend during the recent thermometer period (1850 — 2011) actually is, and what patterns or trends represent «data» in those trends (what the earth's temperature / climate really was during this period), and what represents random «noise» (day - to - day, year - to - random changes in the «weather» that do NOT represent «climate change»), and what represents experimental error in the plots (UHI increases in the temperatures, thermometer loss and loss of USSR data, «metadata» «M» (minus) records getting skipped that inflate winter temperatures, differences in sea records from different measuring techniques, sea records vice land records, extrapolated land records over hundreds of km, surface temperature errors from lousy stations and lousy maintenance of surface records and stations, false and malicious time - of - observation bias changes in the information.)

Also just noticed Table VI in the Chase paper where they give the trends for the surface thermometers.

The warming only comes in because one very southernly island is in the baseline (AND used to fill in grid boxes... I've run the code...) but taken out recently (so grid boxes must look elsewhere for «in fill» and elsewhere is airports closer to the equator...) IIRC, Campbell Island about 68 S. Oh, and in Canada they use ONE thermometer in «The Garden Spot of the Arctic» to get that warming trend north of 65 N.

2nd Conclusion does not appear to be supported with data referenced in Section 3.2; Specifically the conclusion «But, this effect is swamped by the larger effect of siting bias in the non-compliant stations, particularly in the trends of the Tmin, suggesting a sensitivity to heat sinks within the thermometer viewshed, which is the basis of the Leroy classification system».

A thermometer could be placed in a frying pan and yet as long as it has dynamic range available it'll still be able to register a trend in temperature and that trend will be separable from the frying pan component.

3) However, even if the actual variance in TSI during that period was less than 4 Watts per square metre the fact is that various changes in temperature trend did occur and the shape of the chart would remain so on the basis of real world observations we must accept that the lower the range of TSI involved then the more sensitive the Earth is as a water based thermometer.

The global temperature anomaly certainly shows an increase since systematic thermometer records began in the tail end of the period of extreme cold known as the «little ice age», but just as in the medieval warming period, local temperature series need not correspond to the global trend.

assuming what you say about skeptics changing topic as you describe is accurate, and at this point I do we are talking about data that is less than 200 years old, out of which extraordinary claims are made as to how that data relates to distant past and future trends tough sell assuming that all adjustments to the data are scientifically sound, It is very difficult for me to believe that measurements that have gone through so many iterations can be trusted to.0 and.00 in most other sciences, I doubt they would tough sell (the photo of the thermometer is downright funny) in terms of goal post moving I observe predicted heat being re-branded as «missing» a prediction of no snow re-branded as more snow a warming world re-branded to a «warm, cold, we don't know what to expect» world topped off with suggestions that one who thinks the above has some sort of psychological disorder extraordinary claims demand extraordinary evidence especially when you are teaching children that their world is endangered

The warming trend is the same in rural and urban areas, measured by thermometers and satellites, and by natural thermometers.
