«The things acting to reduce malaria spread, like improved healthcare and disease control, are much more powerful than
the weak effect of warming,» Gething says.
Not exact matches
Schlesinger and Ramankutty reach broadly similar conclusions, but they also point out that even though greenhouse gases now dominate global
warming, if part
of the
warming during this century is indeed due to solar changes, the additional greenhouse
effect may be
weaker than was previously thought (Nature, vol 360, p 330).
But then how to explain a similar rapid
warming that occurred during the early 20th century, when the
effects of greenhouse gases were considerably
weaker than today?
«Such a slowdown is consistent with the projected
effects of anthropogenic climate change, where
warming and freshening
of the surface ocean from melting ice caps leads to
weaker overturning circulation,» DeVries explained.
This may help explain some
of the changes that are not explained by the orbital curves in the other thread, especially the initiation
of warming and cooling since the GCR
effects can be much more powerful (partly forcing as postulated in the paper, but also amplification
of the
weaker orbital forcing).
It also helps explain the initial cooling after the Industrial Revolution began (the smoke
effect overwhelmed the relatively
weak warming effect back then), the increase
of global temperture during WW2 (shut down
of industries) and decrease after WW2 (re-industrialization) and acceleration in the 1970's after the passage
of the Clean Air Act.
«Compared to the Arctic, global
warming causes only
weak Antarctic sea ice loss, which is why the IPO can have such a striking
effect in the Antarctic,» explained study's co-author Cecilia Bitz from University
of Washington in a statement.
When it is politically convenient to do so, ENSO is claimed to be an
effect of «global
warming» — i.e. that «global
warming» causes more and larger El Nino and fewer and
weaker La Nina episodes.
I agree with Mike [Mann] that the
weak steering currents over the south - central US coincident with Harvey are consistent with our expectations for a
warmer world, which
of course includes
effects of a very
warm Arctic.»
«I agree with Mike [Mann] that the

effects of a very
warm Arctic,» Jennifer Francis, a climate scientist at Rutgers University, told ThinkProgress.
Of course even a weak effect may be measurable with high precision laboratory equipment, but is it something that you would accept as a full proof of the GH warmin
Of course even a
weak effect may be measurable with high precision laboratory equipment, but is it something that you would accept as a full proof
of the GH warmin
of the GH
warming?
(This is also the reason, why the
warming of real greenhouses is based essentially on stopping convection rather than on the radiative greenhouse
effect, which is in them too
weak to observe.)
The net
effect of these processes taken together is a sustained growth
of the carbon storage in the Southern Ocean, notwithstanding a
weaker global ocean carbon uptake predicted by all models in a
warming climate.
Some
of the late 20th century
warming is therefore from a solar heat lag from the increase in solar output from 1750 - 1950 +, meaning C02
effect is even
weaker than in your paper above.
There is an
effect of a Stratospheric feed - back in winter whereby
weaker UV levels during low solar cause less
warming of the Strat in low latitudes and thereby weaken the Strat deltaT, and giving a nudge to displacement / disruption
of the PV.
Most
of the
warming in climate models is not from CO2 directly but from feedback
effects, and the evidence for strong positive climate feedback on temperature is very
weak (to the point
of non-existence) as compared to the evidence
of greenhouse gas
warming (yes, individual
effects like ice cover melting are undeniably positive feedback
effects, the question is as to the net impact
of all such
effects).

While the upper - troposphere tropical
warming induces a poleward shift
of the jet in winter, Arctic Amplification and a
weaker stratospheric polar vortex result in the opposite
effect.
