Our record is also of interest to climate policy developments, because it opens the door to detailed comparisons between
past atmospheric CO2 concentrations, global
temperatures, and sea levels, which has enormous value to long - term future climate
projections.»

It should say something like «Although CO2 concentrations in the atmosphere have risen in line with earlier
projections, globally - averaged
temperature observations have risen less than projected and are currently at or below the low end of the range in
past IPCC assessments.»
Based on our inferred close relationship between
past and future
temperature evolution, our study suggests that paleo - climatic data can help to reduce uncertainty in future climate
projections.
Research Highlights Summary from Geophysical Fluid Dynamics Laboratory Global
Temperature Projections 100 ° days:
Past and Future
The simulations were shown to reproduce the observed strong reduction in
past crop yields induced by high
temperatures, thereby confirming that they capture one main mechanism for future
projections.
1)... to argue that the observed global mean
temperature anomalies of the
past decade falsifies the model
projections of global mean
temperature change, as contrarians have been fond of claiming, is clearly wrong.
Arctic ice melt is accelerating even faster than the most recent
projections —
temperatures over the
past six years are the highest since measurements began in 1880.
I'm afraid that much of the strength of the reaction to your questions was based on
past experiences - I can not count how many times someone has commented here and on other climate blogs claiming despite the evidence that mismatches between specific
projections and observed
temperatures somehow invalidate all climate modeling, despite the projected emissions not matching actuals.
One element of a compromise that I would suggest is that when referring to
past temperatures and future predictions /
projections that the term «estimated» be used before the number of the
temperature being discussed.
Dana Nuccitelli presented a talk on climate model accuracy — comparing
past global
temperature projections to observations, and effectively debunking associated myths.
«Data from the
past helped calibrate our model, and will improve sea level rise
projections under scenarios of future
temperature increases,» says Rahmstorf.
Let's look in more detail at the paper's key figure, the one that looks at
past and (forecast) future global
temperatures, «Hindcast / forecast decadal variations in global mean
temperature, as compared with observations and standard climate model
projections» (click to enlarge)
The primary reason to ignore chicken little forecasts of thermageddon is the warmists» unquestioned acceptance of WAGs as to
past «global average
temperatures», which is matched only by their blind belief in the
projections of GCMs as to future GATs.
With a growing perspective among editors and reviewers that climate papers must present conclusionary
temperature trends,
projections, and reconstructions in order to proceed
past an initial «fatal flaw» analsys, important contributions to the literature may never make it to the light of day.
