For regional climate predictability, the added value of RCMs should come from better resolving the relationship between mean (temperature) trends and key indicators that are supposedly better represented in the high resolution projections utilizing additional local information, such as temperature or precipitation extremes.
Since IPCC's first report in 1990, assessed projections have suggested global average temperature increases [at least, because of IPCC's accelerated warming claim] between about 0.15 °C and 0.3 °C per decade for 1995 to 2010.
To a naïve observer of temperatures, the difference of temperature between day and night would lead the observer to make extreme projections for the very near future.

The discrepancy between recent observed and simulated trends in global mean surface temperature has provoked a debate about possible causes and implications for future climate change projections.
This point was also made by Schmidt et al. (2014), which additionally showed that incorporating the most recent estimates of aerosol, solar, and greenhouse gas forcings, as well as the El Niño Southern Oscillation (ENSO) and temperature measurement biases, the discrepancy between average GCM global surface warming projections and observations is significantly reduced.
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.
And now — based on sea level behavior between 1930 and 2010, as derived from United States tide gauge data, plus extensions of previous global - gauge analyses — a new empirical study, which does not rely on a relationship between sea level and temperature, casts doubt upon both sets of projections.

It looks like some sort of hybrid between AR4 projections for tropical sea temperature increase and global average surface temperature rise.
it is found that global temperature trends since 1998 are consistent with internal variability overlying the forced trends seen in climate model projections (Easterling and Wehner, 2009; Mitchell et al., 2012b); see also Figure 1.1, where differences between the observed and multimodel response of comparable duration occurred earlier.
While it is difficult to distinguish between the recent slow - down in global surface temperatures and the underlying long - term trend, the slow - down stands out much more vividly when compared to projections from the latest set of GCMs.
