Meehl et al., 2011 (doi: 10.1038 / NCLIMATE1229) show that with a similar radiative imbalance, hiatus periods and non-hiatus periods can occur, and that in the first case larger heat storage in the deep ocean takes place.

«The implication is that we will get fewer hiatus periods, or hiatus periods that last for a shorter period,» says Wenju Cai at CSIRO in Melbourne, Australia, who wasn't involved in the work.

Professor Sybren said: «It can be excluded, however, that this hiatus period was solely caused by changes in atmospheric forcing, either due to volcanic eruptions, more aerosols emissions in Asia, or reduced greenhouse gas emissions.

They relate the current hiatus period at the surface and a deeper penetration of the warming into the ocean with changes in the trade winds on the subtropical Pacific (intensification).

Does someone known if a similar intensification of the trade winds took place during the 1960s explaining then that hiatus period too?

There have been decades, such as 2000 — 2009, when the observed globally averaged surface - temperature time series shows little increase or even a slightly negative trend1 (a hiatus period).

The comparisons for the full 1979 to 2012 term of the Cowtan and Way (2013) are in the left - hand graphs and the «hiatus period» of 1997 to 2012 are shown in the right - hand graphs.

Figure 8 presents model - data trend comparisons for the two warming periods since 1914 and the warming hiatus period from 1945 to 1975.

Both versions of the Cowtan and Way (2013) data have slightly higher long - term (1979 - 2012) warming rates than HADCRUT4, but they have much higher warming rates than HADCRUT4 during the hiatus period of 1997 - 2012.

For example, Figure 7 illustrates the warming and cooling rates of the HADCRUT4 data, and as a reference, the GISS LOTI data, for the period of January 1997 to December 2012... the hiatus period.

This close agreement in the trend of the corrected ship data indicates that these time dependent ship adjustments did indeed correct an artifact in ship data impacting the trend over this hiatus period.»

«The hiatus period gives scientists an opportunity to understand uncertainties in how climate systems are measured, as well as to fill in the gap in what scientists know,» Yan said in a statement.

«the progressive increase in buoy numbers over time between 1990 and 2012 is responsible for skewing the SST trend upwards during the hiatus period.»

But as they say in the main paper, the change in overall global surface temperature trend during the hiatus period is almost entirely due to the 0.064 °C SST trend change between ERSSTv3b and ERSSTv4.

This had its greatest effect during the hiatus period according to the main paper.

So this, most notably the last sentence, bears out what I was saying: the progressive increase in buoy numbers over time between 1990 and 2012 is responsible for skewing the SST trend upwards during the hiatus period.

During this first part of the hiatus period, the heat deficit must be transferred to other ocean basins, mostly to the Pacific because it is the only other major ocean basin in the Northern Hemisphere, likely through the atmosphere.

Dr. Gerald A. Meehl — Nature Climate Change — 18th September 2011 «There have been decades, such as 2000 — 2009, when the observed globally averaged surface - temperature time series shows little increase or even a slightly negative trend1 (a hiatus period)....»
