Atmospheric chemistry-climate feedbacks

Atmospheric chemistry‐climate feedbacks

[1] We extend the theory of climate feedbacks to include atmospheric chemistry. A change in temperature caused by a radiative forcing will include, in general, a contribution from the chemical change that is fed back into the climate system; likewise, the change in atmospheric burdens caused by a chemical forcing will include a contribution from the associated climate change that is fed back in...

Climate/chemistry feedbacks and biogenic emissions.

The oxidizing capacity of the atmosphere is affected by anthropogenic emissions and is projected to change in the future. Model calculations indicate that the change in surface ozone at some locations could be large and have significant implications for human health. The calculations depend on the precise scenarios used for the anthropogenic emissions and on the details of the feedback processe...

The complexity of Atmospheric and Climate Models: Assumptions and Feedbacks

While it is true that the physical principles and equations discussed in part one do form the “core” of any atmospheric or climate model, there are processes in the observed system that are difficult to represent due to our incomplete understanding of the process, or the fact that some processes are not exact. Many of these processes are what we call “feedbacks”. Feedbacks are manifestations of...

Biosphere feedbacks and climate change

POLICY ACTION ON CLIMATE CHANGE IS INFORMED BY CLIMATE MODEL projections as described most recently in the Fifth Assessment Report (AR5) of the Intergovernmental Panel on Climate Change (IPCC). The models used are general circulation models (GCMs), which numerically represent the physical climate system in three dimensions, including the hydrological cycle. These are complemented by recently de...
