Any chemically reactive gas, whether a greenhouse gas or not, will produce some level of indirect greenhouse effect through its
impact on atmospheric chemistry.
«It's an important assessment of where we stand now,» says Veerabhadran Ramanathan of the Scripps Institution for Oceanography, an
expert on atmospheric chemistry who was not involved in the study.
Before she got the grant, Prisle — who studies cloud droplet formation and its
effect on atmospheric chemistry and climate change, combining experimental, theoretical, and computational approaches across multiple disciplines — had struggled to find her place.
I wish that this would be kept in the forefront of everyone's arguments about «what to do»... because there's a different between a feasible and reversible solution and what comes from people who focus is
SOLELY on atmospheric chemistry and exclude the Engineers.
Furthermore, there is a risk that these materials will result in the production of other undesirable species such as nitrous acid and formaldehyde, which can have wider impacts
on atmospheric chemistry as well as adverse health impacts.
Not only that, but following the pessimistic pathways means that we will have already have inflicted so much
violence on the atmospheric chemistry that the extra damage caused by the permafrost feedback will be felt relatively less strongly.
These studies (e.g., Olson et al., 1997) demonstrated a robust consensus about some indirect effects, such as the CH4
impact on atmospheric chemistry, but great uncertainty about others, such as the prediction of tropospheric ozone changes.
It makes the non-CO2 contributions much clearer: Methane now has a more dominant role via its impact
on atmospheric chemistry, and other, more traditional pollutants are included that show clearly the connections between air quality and climate.
He has been a lead author on a number of national and international assessments related to concerns about climate change, and
on atmospheric chemistry, including the effects of human activities on stratospheric and tropospheric ozone.
