recent apparent standstill in global temperature.
Personally I think that
recent research (including several studies discussed in the above post, published after the IPCC AR5 cutoff date) make a strong case that internal variability (ocean cycles) are responsible for more of the
slowdown in surface
warming than changes in external forcings, but there's not a consensus about that yet.
A
recent BBC news story suggested that politicians want a better explanation of a
slowdown in the rate of increase in
warming seen in the last 15 years.
This is powerful evidence that the
recent slowdown in global temperature increase is not a
slowdown of «global
warming,» i.e. man - made climate change, it's simply partial cancellation of global
warming by the natural fluctuations due to ENSO.
And — ironically — their hypothesis is that the
recent slowdown in
warming is from improperly modeled quasi-periodic effect; not an underestimate of sensitivity.
Why is the hypothesis of unusually large internal
warming less unwarranted than the unwarranted assumption that any internally contributed
warming during the late 20th century was equal in magnitude to internally generated cooling during the
recent slowdown?
If you take the running average over 11 years, the
recent slowdown in
warming is somewhat muted.
The statement relies on the unwarranted assumption that any internally contributed
warming during the late 20th century was equal in magnitude to internally generated cooling during the

recent slowdown).
Either way, the results — echoed in a
recent analysis from Japan's Meteorological Agency, which found 1.13 degrees F. above the 20th - century average — indicate that global

Much of the
recent discussion of climate sensitivity in online forums and in peer - reviewed literature focuses on two areas: cutting off the so - called «long tail» of low probability \ high climate sensitivities (e.g., above 6 C or so), and reconciling the
