(In the following text, “Society” shall signify the American Physical Society, “Council” and “Executive Board” shall signify the Council and Executive Board of the Society, respectively; “Executive Officer” shall signify that Officer of the Society.)
ARTICLE I – NAME
This Topical Group of the American Physical Society shall be called the Topical Group on the Physics of Climate, hereafter referred to as the “Topical Group” or “GPC”.
ARTICLE II – OBJECTIVE
The objective of the GPC shall be to promote the advancement and diffusion of knowledge concerning the physics, measurement, and modeling of climate processes, within the domain of natural science and outside the domains of societal impact and policy, legislation and broader societal issues. The objective includes the integration of scientific knowledge and analysis methods across disciplines to address the dynamical complexities and uncertainties of climate physics. Broad areas of initial scientific inquiry are described in the Addendum to these bylaws. These are expected to evolve with scientific progress, while remaining entirely within the domain of natural science.
The GPC Executive Committee, Program Committee, and Communications Committee shall assist in maintaining the scientific focus of the Topical Group by conducting an ongoing and open dialog with Topical Group members concerning the scope and boundaries of scientific interest.
ARTICLE III – ENABLING CONSTITUTIONAL PROVISION
The GPC is established by the authority vested in the Council by Article VIII.1 of the Constitution of the Society. Said Article as it may subsequently be revised or amended, is hereby incorporated into these Bylaws by reference. In accordance with Article XII of the Society Constitution, the GPC is also governed by the Society Bylaws, which are also incorporated herein by reference.

Following Council approval, the Secretary-Treasurer shall distribute copies of the proposed Amendment to all members of the GPC not less than two weeks prior to the next Business Session and opportunity shall be given for discussion during that Business Session. If a special election is not held for membership ratification of the proposed Bylaws Amendments, the Secretary-Treasurer shall again distribute copies thereof in conjunction with the next regularly scheduled election, accompanied by ballot forms and instructions. Adoption of the Amendment shall require a two-thirds affirmative vote of those voting. Council approval is not required for changes to the Addendum.
Initial Areas of Scientific Inquiry:
Five broad areas of scientific inquiry are listed below. These are based on the current (2011) perceived needs of climate science and are likely to change as that science progresses.
- Climate as a complex dynamical system, leading to a better understanding of the natural modes of the climate system, their coupling to each other and to exogenous forces.
- The physics of climate influences, leading to a better understanding of the mechanisms, magnitudes, and timescales by which anthropogenic and non-anthropogenic processes affect climate, including for example, greenhouse gases, solar variability and unforced influences such as internal modes of variability.
- Insight into the nature, magnitude and timescales of climate sensitivity, arising from feedbacks including clouds, water vapor and the hydrological and carbon cycles, at the surface, in the atmosphere, and in the oceans.
- The physics of proxies used to infer the properties of past climates for which instrumental records are not available, leading to a better understanding of past climates and their relation to the present climate.
- The computational physics and statistical analysis of climate model and measurement systems, leading to a better understanding of the methods, capabilities, and limitations of climate models and climate simulation predictions.
Specific science areas underlying these issues include fluid dynamics, modeling of nonlinear systems, the physics of complex systems, gas phase physics and chemistry, radiation/heat transfer, phase transitions, measurement science, computational physics, statistics, and biological physics.
