And since we don't have good
ocean heat content
data, nor any satellite observations, or any measurements of stratospheric
temperatures to help distinguish potential errors in the forcing from internal variability, it is inevitable that there will be more uncertainty in the attribution
for that period than
for more recently.
For example, due to the lack of ocean data, secondary data is often used to infer what the ocean is doing — thus, the AMO analysis relies not on ocean temperature measurements, but rather on air pressure measurements as a proxy for ocean behavior — iffy at be

More than 95 % of the 5 yr running mean of the surface

For example, the sea ice

If we had better sea level rise
data for the whole period, we might see that the heat storage curve into the
ocean had a shape that better matched the simple function approximation than the land surface

temperature response.
Oceanographers have been trying to identify errors in the

The 2005 Jan - Sep land
data (which is adjusted
for urban biases) is higher than the previously warmest year (0.76 °C compared to the 1998 anomaly of 0.75 °C
for the same months, and a 0.71 °C anomaly
for the whole year), while the land -
ocean temperature index (which includes sea surface
temperature data) is trailing slightly behind (0.58 °C compared to 0.60 °C Jan - Sep, 0.56 °C
for the whole of 1998).
But while the graph was only
for SST (sea surface

oceans until a depth of 300 m in the Levitus
data.

If you can point me to a source of complete annual

In summary, I have copies of datasets used in two studies related to Forest 2006, both of which should contain the same
temperature data as used in Forest 2006 (save
for the deep -

data).
The left - hand graph in Figure 6 presents the GISS Land -

We could as easily conclude that snow cover, winter

And
for the period of 1997 to 2012, there are no similarities between the warming and cooling patterns
for lower troposphere
temperatures over the
oceans and the satellite - enhanced sea surface

Students will analyze that
data for evidential links, hypothesize about the possible effect on hurricanes of continual
ocean temperature increases, and predict related implications
for residents of coastal areas.
In summary, the historical [Sea Surface
Temperature] record... may well contain instrumental bias effects that render the
data of questionable value in determining long period trends in
ocean surface
temperatures... Investigators that use the
data [to try this] bear a heavy, perhaps impossible, responsibility
for ensuring that the potential instrument bias has not contaminated their results.
If the paleo

ALL

The
data used in estimating the Levitus et al. (2005a)
ocean temperature fields (
for the above heat content estimates) do not include sea surface
temperature (SST) observations, which are discussed in Chapter 3.
The consistency between these two
data sets gives confidence in the
ocean temperature data set used
for estimating depth - integrated heat content, and supports the trends in SST reported in Chapter 3.
According to
data from the reanalysis produced by the European Centre
for Medium - Range Weather Forecasts, the January to October combined land and
ocean global average
temperature would place 2014 as third or fourth highest

Previous large natural oscillations are important to examine: however, 1) our
data isn't as good with regards to external forcings or to historical
temperatures, making attribution more difficult, 2) to the extent that we have solar and volcanic
data, and paleoclimate
temperature records, they are indeed fairly consistent with each other within their respective uncertainties, and 3) most mechanisms of internal variability would have different fingerprints: eg, shifting of warmth from the
oceans to the atmosphere (but we see warming in both), or simultaneous warming of the troposphere and stratosphere, or shifts in global
temperature associated with major
ocean current shifts which
for the most part haven't been seen.
Using a small number of sites with high - quality
data (e.g. a few sites downwind from each of the three
oceans) might well yield a quality
temperature reconstruction

«It is unfortunate that these government agencies both claim to be scientific, with one responsible
for the U.S. civilian space program (NASA), and the other claims its mission is «to understand and predict changes in climate, weather,
oceans, and coasts» (NOAA), ignore the finest scientific
temperature data available,» the SEPP chief continued.
To conduct the research, a team of scientists led by John Fasullo of the US National Center
for Atmospheric Research in Boulder, Colorado, combined
data from three sources: NASA's GRACE satellites, which make detailed measurements of Earth's gravitational field, enabling scientists to monitor changes in the mass of continents; the Argo global array of 3,000 free - drifting floats, which measure the
temperature and salinity of the upper layers of the
oceans; and satellite - based altimeters that are continuously calibrated against a network of tide gauges.
So, if we could reduce the
