warming than the satellite warming, almost twice as much.
In the 1983 El Nino they showed slightly more
warming than the satellites, in every event since they have show a decreasing response to climate events.

Spencer analyzed 90 climate models against surface temperature and
satellite temperature data, and found that more
than 95 percent of the models «have over-forecast the
warming trend since 1979, whether we use their own surface temperature dataset (HadCRUT4), or our
satellite dataset of lower tropospheric temperatures (UAH).»
Previous work by Hook using
satellite data indicated that many lake temperatures were
warming faster
than air temperature and that the greatest
warming was observed at high latitudes, as seen in other climate

Because water expands as it
warms, that heat also meant that sea surface heights were record high, measuring about 2.75 inches higher
than at the beginning of the

Spencer and Braswell had drawn on NASA
satellite data to try to show that the atmospheres in climate models retain more heat

While observational data from
satellites show less
warming than predicted by most models, Santer and his co-authors demonstrate that the observed
warming is consistent with models including both human and natural forcings, but inconsistent with models using only natural forcings and variability.
However,
satellite observations are notably cooler in the lower troposphere
than predicted by climate models, and the research team in their paper acknowledge this, remarking: «One area of concern is that on average... simulations underestimate the observed lower stratospheric cooling and overestimate tropospheric
warming... These differences must be due to some combination of errors in model forcings, model response errors, residual observational inhomogeneities, and an unusual manifestation of natural internal variability in the observations.»
The scientists who based their research on the information given by
satellites stated that the changes result in the global scale
warming, which is bout 30 percent larger

warming than earth stations, especially in western Europe?
But that does not change the
satellite datas itself, which tells us (one more time): «2015 was NOT
warmer than 1998.»
Large variability reduces the number of new records — which is why the
satellite series of global mean temperature have fewer expected records
than the surface data, despite showing practically the same global
warming trend: they have more short - term variability.
However, there still is an unexplained discrepancy with the very earliest
satellite data showing values that are noticably

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].
Given all the independent lines of evidence pointing to average surface
warming over the last few decades (
satellite measurements, ocean temperatures, sea - level rise, retreating glaciers, phenological changes, shifts in the ranges of temperature - sensitive species), it is highly implausible that it would lead to more
than very minor refinements to the current overall picture.
- temperature sensors on
satellites report much less
warming in the upper atmosphere (which the theory of global
warming predicts should
warm first)
than is reported by temperature sensors on the ground.
What the global change community (through the NRC and CCSP reports) always asserted and then used to discount the radiosonde and UAH
satellite trends was that the deep troposphere should not
warm less
than the surface and in fact based on models globally the troposphere should
warm 1.2 more (the amplification factor).
After using
satellite data and a smart statistical method to fill gaps in the network of weather stations, the global

The» top ten» arguments employed by the relatively few deniers with credentials in any aspect of climate - change science (which arguments include «the sun is doing it», «Earth's climate was changing before there were people here», «climate is changing on Mars but there are no SUVs there», «the Earth hasn't been
warming since 1998», «thermometer records showing heating are contaminated by the urban - heat - island effect», «
satellite measurements show cooling rather
than warming») have all been shown in the serious scientific literature to be wrong or irrelevant, but explaining their defects requires at least a paragraph or two for each one.
And, as the
satellite observations of Spencer and Braswell showed, as the planet
warms over a period of several months, clouds act as a net negative feedback (the reflecting low - altitude clouds increase more
than the absorbing high - altitude clouds with
warming).
The UAH
satellite data, however, shows less

than sufficient to explain the observed
warming surface temperatures.
It is measured by two independent methods (balloons and
satellites) and they both show the
warming at altitude is similar (indeed, slightly less)
than at the surface.
If there was no
warming between 1980 and say around 1996 (the last date for the tree rings) as the
satellite data suggested then the paper should have concluded that the Northern Hemisphere was still some 0.2 to 0.4 degC cooler
than it was in 1940.
Dr. John Christy, director of the Earth System Science Center at the University of Alabama in Huntsville, says the first six months of this year were the second
warmest since the
satellite - measured temperature era began in 1979, and
satellite - measured temperature is more accurate
than temperature measured at weather stations on Earth.
The 2009 State of the Climate report gives these top indicators: humans emitted 30 billion tons of of CO2 into the atmosphere each year from the burning of fossil fuels (oil, coal, and natural gas), less oxygen in the air from the burning of fossil fuels, rising fossil fuel carbon in corals, nights
warming faster
than days,
satellites show less of the earth's heat escaping into space, cooling of the stratosphere or upper atmosphere,
warming of the troposphere or lower atmosphere, etc..
Thus even if the
satellite data showed say nearly 0.1 degC
warming between 1979 to about 1996/7 (which is not statistically significant) then one would expect to see less
than this amount of
warming in the land based thermometer record if the
warming is due to the GHE.
«The
satellite observations suggest there is much more energy lost to space during and after
warming than the climate models show,» Spencer said in a July 26 University of Alabama press release.
The riddle: how does data showing the pause, krigged to
satellite data showing the pause, result in
warming rather
than pause?
Citing the work of Dr. John Christy and Richard McNider at the University of Alabama in Huntsville (UAH), which compared climate model projections with temperatures measured independently by
satellites and weather balloons, he said «the average
warming predicted to have occurred since 1979 (when the
satellite data starts) is approximately three times larger
than what is being observed.»
In addition to contradicting every single United Nations «climate model,» it appears that there has been no
warming trend for more

Of course the differences between incoming and outgoing in our current
warming state are smaller
than can be measured accurately by the
satellites currently flying.
What NASA failed to mention, though, was far more important: The agency's own

warmest since NASA» Remote Sensing Systems (RSS)
satellites went up less
than four decades ago.
-- Except for strongly adjusted temperature data, there is compliance between recent temperatures measured from

Data from NASA's Terra
satellite shows that when the climate
warms, Earth's atmosphere is apparently more efficient at releasing energy to space
than models used to forecast climate change have been programmed to «believe.»
Instead, the
satellite data shows the climate system starting to shed energy more
than three months before the typical
warming event reaches its peak.
