Query: Assessing the consistency between short-term global temperature trends
  in observations and climate model projections   Assessing the consistency between short-term global temperature trends in
observations and climate model projections is a challenging problem. While
climate models capture many processes governing short-term climate
fluctuations, they are not expected to simulate the specific timing of these
somewhat random phenomena - the occurrence of which may impact the realized
trend. Therefore, to assess model performance, we develop distributions of
projected temperature trends from a collection of climate models running the
IPCC A1B emissions scenario. We evaluate where observed trends of length 5 to
15 years fall within the distribution of model trends of the same length. We
find that current trends lie near the lower limits of the model distributions,
with cumulative probability-of-occurrence values typically between 5 percent
and 20 percent, and probabilities below 5 percent not uncommon. Our results
indicate cause for concern regarding the consistency between climate model
projections and observed climate behavior under conditions of increasing
anthropogenic greenhouse-gas emissions.
