As a result, according to the data, there is no sign of
any EXTRA warming due to the green house effect due to human emission of CO2.
Not exact matches
If the
warming was
due to the sun getting hotter, there would be
extra heat arriving during the day but nothing in particular to stop heat loss after dark, so days would
warm faster than nights.
If, for example, it turns out the
extra CO2 released during El Niño is largely
due to microbial activity in soils and decomposing plant material, Malhi says, «I wouldn't expect it to last» as the world
warms further.
The changes seen in the MSU 4 data (as even Roy Spencer has pointed out), are mainly
due to ozone depletion (cooling) and volcanic eruptions (which
warm the stratopshere because the
extra aerosols absorb more heat locally).
Do you agree that when the heating effect of
extra CO2 is
due almost exclusively to what it itself absorbs from outside, but the cooling effect entails an ability to dissipate heat from the additional source, cooling can now outweigh
warming?
However even the moderate scenarios which have eventual stabilisation give more
warming than 0.8 C. Even in the extremely unlikely event that there is no further growth in emissions, the current planetary energy imbalance (estimated to be almost 1W / m2)(
due to the ocean thermal inertia) implies that there is around 0.5 C
extra warming already in the pipeline that will be realised over the next 20 to 30 years.
But this is silly, since the atmospheric lifetime of aerosols is just a matter of days, so once we stop burning coal, as we eventually must, the aerosols disappear quickly, unmasking the pent - up
warming due to all the
extra CO2 we emitted by not switching from coal to natural gas.
I am not convinced that secondary feedbacks will
warm the Earth more than the couple degrees C
due to the
extra CO2 in a century.
«There are now several independent pieces of evidence showing that the earth responds to the
warming due to
extra carbon dioxide by dampening the
warming.
This is the core idea of every official climate model: for each bit of
warming due to carbon dioxide, they claim it ends up causing three bits of
warming due to the
extra moist air.
Global analyses show that the amount of water vapor in the atmosphere has in fact increased
due to human - caused
warming.8, 9,10,11 This
extra moisture is available to storm systems, resulting in heavier rainfalls.
The fact of the matter is that each of these «cooling» trends are all part of a larger picture and if you look at that larger picture the FACT of the matter is, the world is steadily
warming and this
extra warming is
due to the presence of the
extra CO2 mankind is pumping into the atmosphere.
so, yeah, it is really convenient that ocean surface temperatures have gone down since the 1998 el nino
due to wind patterns but that
extra heat going into the ocean is just as much a component of
warming as air temperatures.
So could the
extra warming globally in 2014 be
due to a repeating spike in North Pacific SST and nothing to do with greenhouse gases increase.?
Thirdly, the temperature several decades from now is to a large extent already determined by the current energy imbalance
due to the
extra CO2 already in the atmosphere right now, so short of a complete cessation of emissions today, there is no foreseeable way to avoid the bulk of the
warming that is «in the pipeline».
Others accept (correctly) that that is unlikely
due to the thermal inertia of our oceans and their cooling effect on the air so they propose an «ocean skin'theory whereby
warming of the topmost molecules on the ocean surface from
extra downwelling infra red radiation from
extra human CO2 in the air is supposed to reduce the natural energy flow from sea to air so that the oceans get
warmer and then heat the air and kill us off that way.
