Trump thinks that the only global warming that's going on is found under his toupe.

NASA's mission and history, considered in total, are far beyond amazing.

Laconian or Lamidering Ice Age. I don't know how to spell the first word but it was the Ice Age back when there were Saber Tooth Cats running loose in America.

I was REFERRING to the "no magic thermostat and no magic climate" comment.

Magic thermostat and no magic climate made absolutely no sense to me so I overlooked it but there was a healthy global warming discussion going on.

The satellites are more reliable.

Now explain how fewer and fewer stations in CONUS, with the wizards at NOAA filling in the blanks with estimated data, is reliable? Not to mention doing the same with large swaths of the planet.

And I opened my heart to the whole universe and I found it was loving

And I saw the great blunder my teacher's had made

Scientific delirium madness

30 year trends of temperature are shown to be lower, using well-sited high quality NOAA weather stations that do not require adjustments to the data.

...

Using NOAA’s U.S. Historical Climatology Network, which comprises 1218 weather stations in the CONUS, the researchers were able to identify a 410 station subset of “unperturbed” stations that have not been moved, had equipment changes, or changes in time of observations, and thus require no “adjustments” to their temperature record to account for these problems. The study focuses on finding trend differences between well sited and poorly sited weather stations, based on a WMO approved metric Leroy (2010)1 for classification and assessment of the quality of the measurements based on proximity to artificial heat sources and heat sinks which affect temperature measurement. An example is shown in Figure 2 below, showing the NOAA USHCN temperature sensor for Ardmore, OK.

Following up on a paper published by the authors in 2010, Analysis of the impacts of station exposure on the U.S. Historical Climatology Network temperatures and temperature trends2 which concluded:

Temperature trend estimates vary according to site classification, with poor siting leading to an overestimate of minimum temperature trends and an underestimate of maximum temperature trends, resulting in particular in a substantial difference in estimates of the diurnal temperature range trends

…this new study is presented at AGU session A43G-0396 on Thursday Dec. 17th at 13:40PST and is titled Comparison of Temperature Trends Using an Unperturbed Subset of The U.S. Historical Climatology Network

A 410-station subset of U.S. Historical Climatology Network (version 2.5) stations is identified that experienced no changes in time of observation or station moves during the 1979-2008 period. These stations are classified based on proximity to artificial surfaces, buildings, and other such objects with unnatural thermal mass using guidelines established by Leroy (2010)1 . The United States temperature trends estimated from the relatively few stations in the classes with minimal artificial impact are found to be collectively about 2/3 as large as US trends estimated in the classes with greater expected artificial impact. The trend differences are largest for minimum temperatures and are statistically significant even at the regional scale and across different types of instrumentation and degrees of urbanization. The homogeneity adjustments applied by the National Centers for Environmental Information (formerly the National Climatic Data Center) greatly reduce those differences but produce trends that are more consistent with the stations with greater expected artificial impact. Trend differences are not found during the 1999- 2008 sub-period of relatively stable temperatures, suggesting that the observed differences are caused by a physical mechanism that is directly or indirectly caused by changing temperatures.

1. If the satellite-based measurements are supposedly "more reliable" than the surface-based measurements, then why is the known uncertainty of the satellite-based measurements significantly greater in width in the following chart than the known uncertainty of the surface-based measurements?



Surface Temperature or Satellite Brightness?


2. While the use of less stations tends to increase uncertainty of the temperature anomaly trend, it is entirely unnecessary to have the finest resolution possible to recognize a trend in temperature. Indeed, your argument is the equivalent of concluding that you can only recognize a particular TV program while watching a modern high definition TV when you can recognize the very same TV program while watching an old-fashioned low resolution tube TV.
