What is more, because Jupiter's microwave emissions vary in wavelength based on the pressure (as well as temperature) of the atmospheric layers where they originate, observations at multiple wavelengths allow researchers to create a cross-section through the atmosphere.

Their findings, based on output from four global climate models of varying ocean and atmospheric resolution, indicate that ocean temperature in the U.S. Northeast Shelf is projected to warm twice as fast as previously projected and almost three times faster than the global average.

This was accomplished using a stochastic climate model based on the concept that ocean temperature variability is a slow dynamical system, a red noise signal, generated by integrating stochastic atmospheric forcing, or white noise71.

In the TAR, quantitative evidence for human influence on climate was based almost exclusively on atmospheric and surface temperature.

I am not assuming — there is overwhelming evidence (from copious data, much of which can be found on or linked to from this web site) that global temperatures are rising at a rate that may soon seriously disrupt human civilization, and that the best explanation for the cause of that projection (based on even more data) is human - driven, rising atmospheric CO2 levels.

This elegant, self - regulatory, atmospheric mechanism was soon attacked for being based on limited data and the inability of other researchers to identify the effect in other cloud and temperature data sets.

If so, I think we want to include tightly coupled chemical and biological processes, in that case — for example, the chemical fate of atmospheric methane over time, the effects of increasing atmospheric CO2 on oceanic acid - base chemistry, and the response of the biological components of the carbon cycle to increased temperatures and a changing hydrologic cycle.

The results of the analysis demonstrate that relative to the reference case, projected atmospheric CO2 concentrations are estimated by 2100 to be reduced by 3.29 to 3.68 part per million by volume (ppmv), global mean temperature is estimated to be reduced by 0.0076 to 0.0184 °C, and sea - level rise is projected to be reduced by approximately 0.074 — 0.166 cm, based on a range of climate sensitivities.

While the changes in both the mean and higher order statistical moments (e.g., variance) of time - series of climate variables affect the frequency of relatively simple extremes (e.g., extreme high daily or monthly temperatures, damaging winds), changes in the frequency of more complex extremes are based on changes in the occurrence of complex atmospheric phenomena (e.g., hurricanes, tornadoes, ice storms).

Type 3 dynamic downscaling takes lateral boundary conditions from a global model prediction forced by specified real world surface boundary conditions, such as for seasonal weather predictions based on observed sea surface temperatures, but the initial observed atmospheric conditions in the global model are forgotten.

Even so, Mann said, certain predictions are based on physics and chemistry that are so fundamental, such as the atmospheric greenhouse effect, that the resulting predictions — that surface temperatures should warm, ice should melt and sea level should rise — are robust no matter the assumptions.

For instance, if we divide the respondents into «sceptics» and «warmists» on the basis of their assent to / dissent from the statement, «I believe that burning fossil fuels increases atmospheric temperature to some measurable degree», and then compare those groups» assent to / dissent from popular conspiracy theories, we get the following result:

PRESS RELEASE Comment on «Examination of space - based bulk atmospheric temperatures used in climate research» by Christy et al. (2018) Research Report by James P. Wallace III, Joseph S. D'Aleo, & Craig D. Idso Third Edition, May, 2018

This measure is available for the US from the BEST data set... The reconfirmation now of a strong sun - temperature relation based specifically upon the daytime temperature maxima adds strong and independent scientific weight to the reality of the sun - temperature connection... This suggests strongly that changes in solar radiation drive temperature variations on at least a hemispheric scale... Close correlations like these simply do not exist for temperature and changing atmospheric CO2 concentration.»

But let's do a real rough check, based on the HadCRUT surface temperature record, the Mauna Loa measurement of atmospheric CO2 (after 1958) and the IPCC estimated CO2 level based on the Vostok ice cores (prior to 1958):

Counters: «Once the model finishes producing the data representing how radiative forcing has changed over time, we can then go back and analyze that data to see how the climate system in terms of temperature and other factors will change based on empirical relationships between atmospheric factors and changes in temperature.»

Once the model finishes producing the data representing how radiative forcing has changed over time, we can then go back and analyze that data to see how the climate system in terms of temperature and other factors will change based on empirical relationships between atmospheric factors and changes in temperature.

On the basis of atmospheric CO2 data obtained from the Antarctic Taylor Dome ice core and temperature data obtained from the Vostok ice core, Indermuhle et al. (2000) studied the relationship between these two parameters over the period 60,000 - 20,000 years BP (Before Present).

However, I think your last comment concluding that the rise in atmospheric CO2 not explained by increased ocean temperatures, must therefore be anthropogenic, is unjustified, as it doesn't consider the effect of increased temperature on the land based sources and sinks.

The above statement was based on strong evidence available at that time that the Sensitivity of Earth Temperature to increased atmospheric CO2 was not significant and was vastly over-estimated by the climate models cited by the IPCC.

Based on an extensive literature review, we suggest that (1) climate warming occurs with great uncertainty in the magnitude of the temperature increase; (2) both human activities and natural forces contribute to climate change, but their relative contributions are difficult to quantify; and (3) the dominant role of the increase in the atmospheric concentration of greenhouse gases (including CO2) in the global warming claimed by the Intergovernmental Panel on Climate Change (IPCC) is questioned by the scientific communities because of large uncertainties in the mechanisms of natural factors and anthropogenic activities and in the sources of the increased atmospheric CO2 concentration.

This comment has already gotten too long, but I'd like to point out that based on what we know so far, it looks very much as if Salby is making the same mistake that McLean made (in attributing the temperature rise to ENSO) and, even more similarly, that Mr Lon Hocker made in a post at WUWT in which he made virtually the identical argument to this one (temperature changes explain the atmospheric CO2 trend).

Bottom is model results based on: observed SST; modeled atmospheric profile for temperature and humidity; plus effect of trace gases:

Based on the understanding of both the physical processes that control key climate feedbacks (see Section 8.6.3), and also the origin of inter-model differences in the simulation of feedbacks (see Section 8.6.2), the following climate characteristics appear to be particularly important: (i) for the water vapour and lapse rate feedbacks, the response of upper - tropospheric RH and lapse rate to interannual or decadal changes in climate; (ii) for cloud feedbacks, the response of boundary - layer clouds and anvil clouds to a change in surface or atmospheric conditions and the change in cloud radiative properties associated with a change in extratropical synoptic weather systems; (iii) for snow albedo feedbacks, the relationship between surface air temperature and snow melt over northern land areas during spring and (iv) for sea ice feedbacks, the simulation of sea ice thickness.

Under the plan, scientists and experts from around the world will be able to trade contracts based on the atmospheric concentration of carbon dioxide and how far temperatures increase, going decades into the future.

With the ever increasing divergence of surface temperatures from satellite ones, and the subsequent divergence of overheated climate models to observed reality, it is worth a background on atmospheric measurement systems from former NASA climate scientist Dr. Roy Spencer, Ph.D. — climatologist at the University of Alabama in Huntsville who he developed the first temperature record based on satellites...

Based on the gold - standard empirical evidence, it can safely be said that the increased atmospheric CO2 levels of 2016 had little acceleration impact, if any, since the earlier period - at a much lower level CO2 - exhibited greater atmospheric temperature acceleration.

Oakwood, the tragedy is not what's happening in science — things there are just as they should be: the field continues to develop new data and refined analyses, general conclusions have been reached that a very large majority support, based on well - established principles (properties of CO2, thermodynamics, effects of warmer air on evaporation...) and data (measures of CO2 levels, shifts in isotopic composition of atmospheric CO2, temperature records — instrumental and proxy,...).

Specifically, key parameters of the Human System, such as fertility, health, migration, economic inequality, unemployment, GDP per capita, resource use per capita, and emissions per capita, must depend on the dynamic variables of the Human — Earth coupled system.26 Not including these feedbacks would be like trying to make El Niño predictions using dynamic atmospheric models but with sea surface temperatures as an external input based on future projections independently produced (e.g., by the UN) without feedbacks.

If CO2 (and its «back radiation») had any significant effect, then a person would expect that, at the same atmospheric pressure, an almost - all - carbon - dioxide - atmosphere would show a much greater «greenhouse effect», but what the almost - all - carbon - dioxide - atmosphere shows is ONLY an incremental temperature increase based on closer proximity to the Sun.

That method, which we use in the NASA / GISS GCM, extrapolates the surface pressures to sea level based on elevation and the atmospheric lapse rates calculated from surface air temperatures.

The original Petition was substantially based on a major peer - reviewed 2016 scientific paper by James Wallace, John Christy and Joseph D'Aleo (Wallace 2016) that analyzed the best available temperature data sets and «failed to find that the steadily rising atmospheric CO2 concentrations have had a statistically significant impact on any of the 13 critically important tropical and global temperature time series data sets analyzed.»

The researchers, most of them based at Columbia University's Lamont - Doherty Earth Observatory, say it cements the theory that atmospheric moisture, and thus dust, move in close step with temperature on a global scale; the finding may in turn help inform current ideas to seed oceans with iron - rich dust in order to mitigate global warming.

What is lacking are a) a statistically robust correlation between atmospheric CO2 and global temperature (original topic of this thread) and b) empirical data based on physical observations to support the AGW premise.
