Much work is being done on improving the realism of such effects — particularly through ozone chemistry (which enhances the signal), and aerosol pathways (which don't appear to have much of a global effect i.e. Dunne et al. (2016)-RRB-.

It is actually quite difficult to work that out and depends enormously on what kind of environment the extra clouds / aerosols are in (this is one of the big «missing steps»).

As I said to Andy Revkin (and he published on his blog), the additional decade of temperature data from 2000 onwards (even the AR4 estimates typically ignored the post-2000 years) can only work to reduce estimates of sensitivity, and that's before we even consider the reduction in estimates of negative aerosol forcing, and additional forcing from black carbon (the latter being very new, is not included in any calculations AIUI).

[T] here have now been several recent papers showing much the same — numerous factors including: the increase in positive forcing (CO2 and the recent work on black carbon), decrease in estimated negative forcing (aerosols), combined with the stubborn refusal of the planet to warm as had been predicted over the last decade, all makes a high climate sensitivity increasingly untenable.

This paper re-states the grand Svensmark theory and attempts to address the work that has shown cosmic rays can not be a significant influence on climate because most aerosols run out of stuff to become big enough for cloud formation.

Here are a few of the problems that need to be worked out: There's the issue of the effect of the aerosols on stratospheric chemistry (think how unanticipated the chemistry of the Ozone Hole was), and the question of just where the aerosols would go once injected.

Contribution from working group I to the fifth assessment report by IPCC TS.5.4.1 Projected Near - term Changes in Climate Projections of near - term climate show small sensitivity to Green House Gas scenarios compared to model spread, but substantial sensitivity to uncertainties in aerosol emissions, especially on regional scales and for hydrological cycle variables.

The cosmic ray particles work let's say like a «glue» that puts together all the already formed condensation nuclei in the atmospheric air, creating therefore bigger condensation nuclei and finally the clouds, or the cosmic particles act as aerosols on their own, on which the water vapour condenses?

Prof Piers Forster, a physical climate scientist at Leeds University and lead author of the chapter on clouds and aerosols in working group one of the last IPCC report, tells Carbon Brief:

Postdoctoral work at Environment Canada and at the University of Manchester Institute of Science and Technology (UK) gave her opportunities to develop research on cloud - aerosol interactions through in - situ measurements with research aircraft.

But Julian, a simple model - obs matchup in the temperature field is not how formal attribution is done, and I agree that the aerosol forcing uncertainty makes such simple comparisons problematic (see Knutti's work on this for example).

The models adjusted this correlation and tried to blame aerosols on this, but the main problem being adjusting for warming periods and recent non-warming period it just doesn't work at all.

I've done it with the ENSO signal once, but I didn't figure out how to do it with the volcanic aerosol signal until just recently, so I'm still working on this one.

Furthermore, conceptual work on the potentially chaotic nature of the ISM (70) has been developed (V. Petoukhov, K. Zickfeld, and H.J.S., unpublished work) to suggest that under some plausible decadal - scale scenarios of land use and greenhouse gas and aerosol forcing, switches occur between two highly nonlinear metastable regimes of the chaotic oscillations corresponding to the «active» and «weak» monsoon phases, on the intraseasonal and interannual timescales.

I, on the other hand, am worried about the impact of a technology that has unknown consequences for the environment, and which in some regards is definitely known not to work — c.f the fact that it does nothing for ocean acidification, and also the implications of the mismatch in time scale between aerosols and CO2.

I am currently working on a variety of topics related to aerosol research and their sources, sinks, and interactions with climate at various levels of complexity.
