This Bern model incorporates non-linear
ocean chemistry feedbacks and CO2 fertilization of the terrestrial biosphere, but it omits climate - carbon feedbacks, e.g., assuming static global climate and ocean circulation.

The policy problem is a chain of numbers, each of which can be assigned a clear, unambiguous, unmetaphysical estimated probability distribution: the emissions trajectory, the carbon cycle
feedbacks, the climate response, the
ocean chemistry response, the ice sheet response, the impacts, these are all quantitative.
Changes in
ocean chemistry, which can be described through the Revelle buffer factor [1], limit oceanic removal of CO2 [2], while the potential for terrestrial vegetation to take up CO2 is also predicted by some models to fall as the climate warms [3], although the size of this
feedback is uncertain [4].
These
feedback processes are related to things such as clouds, water vapor, ice, changes in
ocean chemistry, and changes in vegetation.
Polar albedo changes, hurricanes,
ocean dynamics, forest
feedbacks, soil
chemistry, boundary layer physics, global solar energy fluxes, cloud
feedbacks, etc..
It didn't get a lot of discussion before it closed; this area includes the unexpected
feedbacks for which we have known good science —
ocean chemistry.
Topics that I work on or plan to work in the future include studies of: + missing aerosol species and sources, such as the primary oceanic aerosols and their importance on the remote marine atmosphere, the in - cloud and aerosol water aqueous formation of organic aerosols that can lead to brown carbon formation, the primary terrestrial biological particles, and the organic nitrogen + missing aerosol parameterizations, such as the effect of aerosol mixing on cloud condensation nuclei and aerosol absorption, the semi-volatility of primary organic aerosols, the importance of in - canopy processes on natural terrestrial aerosol and aerosol precursor sources, and the mineral dust iron solubility and bioavailability + the change of aerosol burden and its spatiotemporal distribution, especially with regard to its role and importance on gas - phase
chemistry via photolysis rates changes and heterogeneous reactions in the atmosphere, as well as their effect on key gas - phase species like ozone + the physical and optical properties of aerosols, which affect aerosol transport, lifetime, and light scattering and absorption, with the latter being very sensitive to the vertical distribution of absorbing aerosols + aerosol - cloud interactions, which include cloud activation, the aerosol indirect effect and the impact of clouds on aerosol removal + changes on climate and
feedbacks related with all these topics In order to understand the climate system as a whole, improve the aerosol representation in the GISS ModelE2 and contribute to future IPCC climate change assessments and CMIP activities, I am also interested in understanding the importance of natural and anthropogenic aerosol changes in the atmosphere on the terrestrial biosphere, the
ocean and climate.
