«Non-linear» animal reactions He and his colleagues based their analysis on nearly 500 million temperature

Some of the discontinuities (which can be of either sign) in
weather records can be detected using jump point analyses (for instance in the new version of the NOAA product), others can be adjusted using known information (such as biases introduced because changes in the time of observations or moving a
station).

(If scientists with such a range of views agree that this work is valid, that seems to cut against arguments over the reliability and utility of temperature
records gathered by
weather stations — or am I missing something?)
Some, but not all, UK
weather stations have
records of soil temperature dating back over 100 years.
Some of the discontinuities (which can be of either sign) in
weather records can be detected using jump point analyses (for instance in the new version of the NOAA product), others can be adjusted using known information (such as biases introduced because changes in the time of observations or moving a

In this case, they have the long
records from the
weather stations, and the relationship of the wider temperatures to those
stations over the satellite period, and this is what you get when you put that together.
Then came Watts's new paper, which — as with his earlier efforts — is focused on questioning the quality of decades of temperature
records generated by
weather stations across the lower 48 states.
(BTW, you have to carry out special procedures to compensate for movement of
weather stations in the anomoly
record, which is why looking at raw data can be very misleading if the
station has moved or procedures were changed.
Secondly, through the copious use of
station weather data, a number of single
station records with long term cooling trends are shown.
The mean temperature change or the OHC increase is an integral over all of that and therefore can be estimated to higher precision than any individual reading (just like for the
weather station record).
My own analysis for my neck - of - the - woods (slightly less definite due to the data from the local

Back in ’88 there was still quite a debate about whether the world was in fact warming or whether the temperature

Meanwhile, on July 21, 2016, as an intense heat wave gripped the Middle East and Southwest Asia, a

That's easy to do with the year 1300, but lately there's been some evidence to suggest that, because the actual climate has spent the entire 21st century refusing to follow the alarmist models and broil the planet, NOAA and NASA have had to resort to cooling the recent past - ie, not the pre-thermometer millennium - old past but the
weather -
station recorded - temperature living - memory past.
It possible that by understanding the possible warming bias and inaccuracies in surface
weather stations that can gain more confident in using these
records, thereby have longer accurate
record of average temperatures.
So, initially, these estimates might seem to provide a useful comparison for the
weather station records.
The main basis for the claim that there has been «unusual» global warming since the late 19th century is that the global temperature estimates constructed from
weather station records suggest a warming trend of about 0.8 - 1.0 °C since about 1880.
However, as we will discuss in this essay, many of the
weather station records used for these estimates of global warming contain artificial warming biases, which are not representative of actual global temperatures.
Science Corrupted: It's «the hottest year on
record», as long as you don't take its temperature — Activist James Hansen's claims based on «pure conjecture» — Hansen's Climate Con: «The parts of the world which GISS shows to be heating up the most are so short of
weather stations that only 25 per cent of the figures are based on actual temperature readings»
Average annual temperatures
recorded at the Buenos Aires
weather station.
So, this has led many people to conclude that the «unusual» global warming implied by the
weather station records is man - made global warming from our fossil fuel usage.
Combining the greater share of
weather stations in more urban areas over time with this urban heat effect also tends to increase the rate that
recorded temperatures tend to rise over time.
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.
This would have introduced an artificial warming trend into the
weather station's
record, i.e., it would introduce an «urbanization bias».
The main basis for the claim that there has been «unusual» global warming since the Industrial Revolution arises from the various global temperature estimates constructed from
weather station records.

Aside from the problems urban heat islands can cause for city - dwellers, they also create an insidious problem for researchers who want to use
weather station records to estimate global temperature trends.
