The crux of Bates» claim is that NOAA, the federal government's top agency in charge of
climate science, published a poorly - researched but widely praised study with the political goal of disproving the controversial global

Then when climategate triggered me to closely examine everything, notably the IPCC's attribution argument, I realized that the fingerprints were «muddy», the

warming 1910 - 1940, the cooling 1940 - 1976, and the
hiatus since 1998.

To be perfectly clear: Talk of a «
hiatus» or a «pause» in global
warming has been a contrarian talking point for about a decade, and there is clear evidence that this framing was picked up by the media (see Max Boykoff's article in Nature
Climate Change last year) and has now been picked up by some climate scie
Climate Change last year) and has now been picked up by some
climate scie
climate scientists.
We're in the midst of a «
hiatus decade», but as Christy's own figure shows, the observed
warming is nevertheless consistent with the envelope of model runs, because

hiatus decades to sometimes occur.
Building on earlier work, the
climate model examined by Meehl et al (2011) & (2013) demonstrated that
hiatus decades (decades in the model with little or no surface
warming) occurred when anomalous heat was being taken up by the deep ocean.
Interpretation of
climate model simulations has emphasized the existence of plateaus or
hiatus in the
warming for time scales of up to 15 - 17 years; longer periods have not been previously anticipated, and the IPCC AR4 clearly expected a

Climate Models and the
Hiatus in Global Mean Surface
Warming of the Past 15 Years «The observed global mean surface temperature (GMST) has shown a much smaller increasing linear trend over the past 15 years than over the past 30 to 60 years (Section 2.4.3, Figure 2.20, Table 2.7; Figure 9.8; Box 9.2 Figure 1a, c).
I have not trusted the
climate change models for a long time and the ongoing
hiatus in
warming leads me to trust them even less.
The widespread mainstream media focus on the slowed global surface
warming has led some
climate scientists like Trenberth and Fasullo to investigate its causes and how much various factors have contributed to the so - called «pause» or «
hiatus.»
Some have turned to solar activity or natural
climate cycles to explain the
hiatus in
warming.
These include claiming that addressing
climate change will keep the poor in «energy poverty»; citing the global
warming «
hiatus» or «pause» to dismiss concerns about
climate change; pointing to changes in the
climate hundreds or thousands of years ago to deny that the current
warming is caused by humans; alleging that unmitigated
climate change will be a good thing; disputing that
climate change is accelerating sea level rise; and denying that
climate change is making weather disasters more costly.
So no matter how many record
warming years you have according to the simple weather or yearly cycles estimations, or how many such record years you may «produce», it does not really mean anything in
climate terms,............... that is why these crazy records make not even a dent to the plateau or the
hiatus... or put another way....
Gee, now why would all of those main stream media outlets and
climate scientists be discussing the
warming hiatus right now?

climate community replaces the term «global
warming hiatus» with «global surface
warming slowdown» to avoid confusion.
But it looks like an increasingly desperate move when seen in the light of mainstream scientists scratching their heads about the global
warming hiatus, and the non-manifest problems that
climate change orthodoxy of yesteryear promised we should be expecting by today.
