At the American Society of Clinical Oncology (ASCO) 2017 Annual Meeting, we presented monotherapy data of nine patients who received G100 with radiation (no pembrolizumab) that showed 100 % DCR rate, with 44 % of the patients achieved a partial response (PR) based on WHO criteria, which requires at least a 50 % tumor reduction to qualify as a PAt the American Society of Clinical Oncology (ASCO) 2017 Annual Meeting, we presented monotherapy data of nine patients who received G100 with radiation (no pembrolizumab) that showed 100 % DCR rate, with 44 % of the patients achieved a partial response (PR) based on WHO criteria, which requires at least a 50 % tumor reduction to qualify as a Pat least a 50 % tumor reduction to qualify as a PR.

More importantly, this system has the very nice property that the global mean of instantaneous forcing calculations (the difference in the radiation fluxes at the tropopause when you change greenhouse gases or aerosols or whatever) are a very good predictor for the eventual global mean response.

My contribution had its ups and downs — a low point was definitely when Judge Alsup declared «your chart sucks» in response to a powerpoint slide (right) which showed an artist's impression of the Nimbus 4 satellite at the expense of a graph of how the spectrum of outgoing long wave radiation changed in response to rising greenhouse gases between 1970 and 1997.

Earth's energy balance In response to a positive radiative forcing F (see Appendix A), such as characterizes the present - day anthropogenic perturbation (Forsteret al., 2007), the planet must increase its net energy loss to space in order to re-establish energy balance (with net energy loss being the difference between the outgoing long - wave (LW) radiation and net incoming shortwave (SW) radiation at the top - of - atmosphere (TOA)-RRB-.

Adding CO2 does not (at least not before the climate response, which is generally stratospheric cooling and surface and tropospheric warming for increasing greenhouse gases) decrease the radiation to space in the central portion of the band because at those wavelengths, CO2 is so opaque that much or most radiation to space is coming from the stratosphere, and adding CO2 increases the heights from which radiation is able to reach space, and the stratospheric temperatures generally increase with increasing height.

Refering to bands where optical thickness is constant over the interval of each band, if the atmospheric LW absorption is limited to some band (that doesn't cover all LW radiation), than increases in OLR in response to surface warming will occur outside that band, so OLR will drop within the band — there will still be some portion of stratospheric or near - TOA cooling that will be transient, but some will remain at full equilibrium.

The equilibrium response to an addition of RF at a level is an increase in net upward flux consisting of LW radiation (the Planck response, PR) plus a convective flux response CR; CR is approximately zero at and above the tropopause in the global time average.

Re 9 wili — I know of a paper suggesting, as I recall, that enhanced «backradiation» (downward radiation reaching the surface emitted by the air / clouds) contributed more to Arctic amplification specifically in the cold part of the year (just to be clear, backradiation should generally increase with any warming (aside from greenhouse feedbacks) and more so with a warming due to an increase in the greenhouse effect (including feedbacks like water vapor and, if positive, clouds, though regional changes in water vapor and clouds can go against the global trend); otherwise it was always my understanding that the albedo feedback was key (while sea ice decreases so far have been more a summer phenomenon (when it would be warmer to begin with), the heat capacity of the sea prevents much temperature response, but there is a greater build up of heat from the albedo feedback, and this is released in the cold part of the year when ice forms later or would have formed or would have been thicker; the seasonal effect of reduced winter snow cover decreasing at those latitudes which still recieve sunlight in the winter would not be so delayed).

So water dances at many speeds, from the unimaginable fast vibrations of its molecules responding to thermal infrared radiation, to the moment - to - moment dance of its phase changes in response to temperature changes, to the week - long dance of its vapor in and out of the atmosphere, to the slow geological pavanes of rock, air and life, of which it too forms an inextricable part.

In other words, rather than presenting climate engineering, and especially solar radiation management (rebranded «albedo modification»), as an extreme response to be avoided if at all possible, the report normalises climate engineering as one approach among others.

The IPCC model suggests that the heat and latent energy exchange between the underlying surface and the atmosphere is a direct response to the imbalance of solar energy and terrestrial radiation at the surface.
