Meetings, Workshops, Seminars, and Colloquia
Most seminars and colloquia at NASA/GISS are presented during the academic year, September through May.
Informal lunchtime seminars (most often presented by NASA/GISS, Columbia/EI, and/or Columbia/LDEO) take place on Wednesdays at 1:00 p.m. about twice per month.
Formal seminar presentations by visiting scientists are held many fridays at 11:00 a.m.
Snince late 2019, GISS staff have organized a Tuesday morning series of Sea Level Rise seminars (YouTube). Presentations are made by scientists from varied institutions.
Following are upcoming seminars, workshops and other events of interest to GISS staff and to our research partners. Please note that due to security regulations, as described elsewhere on this page, presentations on the GISS premises are not open to the general public.
Events marked "Virtual Only" are presented on-line for remote attendance only. Please consult with the event contact/host for connection details.

Sea Level Rise Seminar
Speaker: Madison Smith (Univ. Washington)
Title: On pancakes and polynyas: The role of waves in sea ice formation
This is an on-line, virtual presentation only. Please consult with event host Craig Rye for connection details.
Abstract:
The wave climate of the Southern Ocean is among the most extreme in the world, and recent substantial loss of sea ice coverage in the Arctic Ocean has resulted in a large seasonal wave. Waves are attenuated far into the sea ice, but are a defining feature of the marginal ice zone, as well as coastal polynyas, where strong winds away from the coast result in rapid ice formation. Thus, the generation and propagation of waves in ice-covered regions has a key role in ice formation. Observations of waves in both environments illuminates the associated processes. Incorporation of the empirical results into new coupled wave-sea ice models aims to improve our understanding of the role of floe-scale interactions in the larger ice pack, and likely has implications for regional water mass transformation.

GISS Lunch Seminar
Speaker: Ivan Mitevski (CU/APAM)
Title: Non-monotonic Response of the Climate System to Abrupt CO2 Forcing
This is an on-line, virtual presentation only. Please consult with event host Clara Orbe for connection details.
Abstract:
We explore the climate system response to abrupt CO2 forcing, spanning the range 1x to 8xCO2, with two state-of-the-art coupled atmosphere-ocean-sea-ice-land models: the NASA Goddard Institute for Space Studies Model E2.1-G (GISS-E2.1-G) and the Community Earth System Model (CESM-LE). We find that the effective climate sensitivity is a non-monotonic function of CO2 in both models, reaching a minimum at 3 xCO2 for GISS-E2.1-G, and 4 xCO2 for CESM-LE. A similar non-monotonic response is found in Northern Hemisphere surface temperature, sea-ice, precipitation, the latitude of zero precipitation-minus-evaporation, and the strength of the Hadley cell. Interestingly, the Atlantic meridional overturning circulation collapses when non-monotonicity appears and does not recover for larger CO2 forcings. Analyzing the climate response over the same CO2 range with slab-ocean versions of the same models, we demonstrate that the climate system's non-monotonic response is linked to ocean dynamics.

Security Note
Federal regulations require that visitors to NASA/GISS arrange in advance for a building pass. Persons attending a GISS seminar or colloquium should contact the event host at least two days in advance of the event for assistance. Please include your affiliation in your e-mail.
Due to implementation of the REAL ID Act (2005), a state driver's license or identification card is currently (as of spring 2020) required for admittance to the GISS premises, which is considered a federal facility. However, if you have a state-issued license or ID that is not considered REAL-ID compliant, you are urged to obtain one before entrance regulations change, which is expected to occur Oct. 1, 2021.
Persons who are not U.S. citizens or U.S. permanent residents and who may be planning a visit to GISS require that special arrangements be made. Please co-ordinate with your GISS host on this at least three weeks before your visit.
All visitors can expect to have their bags searched upon entry to GISS. This may include having to answer questions about personal items, including any medication the visitor may be carrying.
