Seminars and Colloquia

Most seminars and colloquia at NASA's Goddard Institute for Space Studies are presented during the academic year, September through May.

Informal Lunch Seminars take place on Wednesdays at 1 p.m. about twice per month, mostly during the academic year. As of 2023, these events are usually "hybrid", i.e., they are presented in person at GISS but may be attended remotely by obtaining connection details from the event host.

GISS staff also organize a Tuesday morning (11 a.m.) series of Sea Level Rise Seminars (YouTube recent, older) presented by scientists from numerous research institutions. This seminar is entirely "virtual" and occurs two or three times per month, year-round.

Other special seminars may occur depending on the schedules of visiting scientists.

Schedule

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.

Please consult with the event host/contact for connection details if you wish to remotely join any event marked as "Virtual" or "Hybrid".

Special Seminar
Speaker: Cristian Proistosescu (UIUC)
Title: How regional temperature patterns modulate global warming trends


Abstract:
I will highlight recent progress on understanding the coupling of sea surface temperature patterns, atmospheric circulation, clouds, and radiation: a coupling that has come to be known as "the pattern effect". This pattern effect has large implications for both attributing recent global warming trends as well as projecting future ones. Specifically, I will show that the regional pattern of temperature change over 1981 to 2014 has led to a temporary slowdown of global-mean warming over this period -- a slowdown that climate models fail to replicate due to systematic biases in their simulations of regional temperature trends in the Pacific.

GISS Lunch Seminar
Speaker: Gianluca Meneghello (Ecole Normale Superieure)
Title: The Dynamics of the Arctic Ocean


This is hybrid presentation. Please consult with event host Maggie DeLessio for connection details if you wish to virtually attend.


Abstract:
The Arctic Ocean is one of the fastest changing and least understood environments on the planet. It is also a crucial element of the global climate system. Yet, predicting the future of this high-latitude ocean presents challenges. Many of the processes regulating its evolution are still poorly understood, and the Arctic is one the largest sources of uncertainty in climate projections.

In this talk I will discuss how we can leverage observations and reduced-order models to investigate the dynamical balance regulating the Arctic's large-scale circulation and mesoscale turbulence field. At the large scale, we will discuss how the feedback between sea-ice drift and surface currents plays a central role in modulating the momentum transfer between the atmosphere and the ocean. At the mesoscale, we will see how the interplay between sea-ice and stratification leads to the peculiar subsurface intensification of the Arctic's eddy kinetic energy. We will then review possible implications for modeling the future evolution of the Arctic Ocean.

Security Note

Federal regulations require that visitors to NASA/GISS arrange in advance for a building pass. Persons planning to attend a GISS seminar or colloquium held on-site at the institute should contact the event host several days in advance of the event for assistance.

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.

Due to implementation of the REAL ID Act (2005), a passport, state driver's license or state identification card is required for admittance to the GISS premises, which is considered a federal facility. If you do not have a state-issued license or ID that is considered REAL-ID compliant, we urge you to obtain one before one is required to enter a federal facility. Enforcement of this requirement was delayed due to the COVID pandemic and is now expected to begin in May 2025.

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.
