The research shows that a one degree rise in tropical temperature leads to around two billion extra tonnes of carbon being released per year into the atmosphere from tropical ecosystems, compared with
the same tropical warming in the 1960s and 1970s.

Rapid decomposition facilitated by
warm temperatures and abundant moisture in these
same tropical regions slowed the accumulation of organic matter that was not protected from microbial decomposers.
So far the team has looked only at data from the Pacific Ocean region, but if other
tropical oceans have the
same effect, Earth may be well equipped to handle global
warming.
At the
same time the lifetime of atmospheric ozone is short due to the exceptionally
warm and moist conditions in the
tropical West Pacific.
At the
same time, the PDO — driven by ENSO
warming in the
tropical eastern Pacific Ocean — has become less common.
All three have the
same ingredients:
warm tropical ocean water, atmospheric moisture, and light winds.
However, models do not get quite the
same distribution of
warming seen in the observations; the observations tend to show less tropospheric
warming and more stratospheric cooling in
tropical regions (e.g. 20 South to 20 North).
While El Niño features
warmer - than - normal ocean waters in the central and eastern
tropical Pacific — much
warmer in the case of this exceptional El Niño — La Niña features colder - than - normal waters in the
same region.
In a series of papers, we've shown that the
warmer temperatures observed over the WAIS are the result of those
same atmospheric circulation changes, which are not related to the SAM, but rather to the remote forcing from changes in the
tropical Pacific: changes in the character of ENSO (Steig et al., 2012; Ding et al., 2011; 2012).
As far as I know, the 2 main sources of satellite data for temperatures in the lower troposphere are UAH and RSS, and they vastly differ in their trends in the
tropical troposphere, with RSS's trend being twice as
warming as the UAH trend, although they show the
same trends in the remaining troposphere, resulting in a Global difference of only 0.035 C / d trend.
I made the
same argument on the slowing of the
tropical mass circulation in a
warmer climate, based on Betts and Ridgway (JAS1989) and the difference of the slopes of the Clausius - Clapyron and the radiative cooling
Currently most of Earth's
warming is done in
tropical area of Earth, which the
same if Earth was at Venus distance.
Tropical and mid latitude Pacific simply do not
warm at the
same time.
** We note, however, that the atmosphere, both over land and ocean, did not
warm during this
same post-1978 period — even though atmospheric theory and every climate model predicts that the
tropical atmosphere should
warm nearly twice as rapidly as the surface.
In the
same time
tropical West Africa (where the pied flycatcher spends its winters) is also
warming, but not equally fast.
If
warming prior to 1960 is 0.5 or greater, pretty much a given with the
tropical reconstruction, Solar, aerosols, land use etc. can have have more impact than CO2 equivalent gases so your Half or complete baked explanation is going to need dLOD, fair dust and unicorns to get all the «consensus» players on the
same page.
The
same warming at the lowest latitudes could be devastating: in some
tropical regions, conditions could become too hot and dry for any growth.
I showed that the height of the water column of the
tropical Pacific reflected the
same rise as the 1995/96 OHC, countering your inference that a pocket of
warm water rose up from below the 700 meter depth in the
tropical Pacific.
If water vapor has an amplifying effect as climate modelers claim, why is the daily mean temperature in a dry, desert area
warmer (in spite of nighttime cooling) than a humid
tropical area at the
same latitude?
An implication of the GFDL studies is that if the frequency of
tropical cyclones remains the
same over the coming century, a greenhouse - gas induced
warming may lead to an increasing risk globally in the occurrence of highly destructive category - 5 storms.
