Friday Seminar
Speaker: Laura Wilcox (University of Reading)
Title: The role of anthropogenic aerosol in near-term climate uncertainty

Abstract: The uncertainty in radiative forcing due to anthropogenic aerosol has been intractable for the last 20 years, and is the dominant uncertainty in estimates of global radiative forcing. Uncertainty in aerosol forcing has implications for centennial scale climate projections, where it limits our ability to estimate climate sensitivity. It is also important for near-term (20-40 year) projections, where the substantial spread in aerosol emission pathways is compounded by uncertainty in the response to these emissions. In addition to there being large uncertainties in the forcing itself, uncertainties in the dynamical response to forcing contribute to large overall uncertainty in the regional climate response to anthropogenic aerosol changes. This combination of scenario, radiative, and dynamical uncertainty makes anthropogenic aerosol the main factor in the spread in near-term climate projections, and an important consideration for meeting the targets of the Paris Agreement. In this talk I will describe the influence of aerosol forcing uncertainty on simulations of historical climate with HadGEM3-GC3.1, and show our recent attempt to constrain estimates of historical aerosol forcing. I will then turn to the future and examine the role of aerosol forcing uncertainty, and scenario uncertainty, in projections of climate to 2050. Aerosol scenario uncertainty is particularly pronounced over Asia, and I will use the latter stages of the talk to show some of the effects of uncertainty in the parameterisation of aerosol-cloud interactions, uncertainty in dynamical feedbacks, and potential feedbacks between the responses to regional emission changes, on near-term projections in this region.

GISS Lunch Seminar
Speaker: David Lindo-Atichati (CUNY)
Title: What are Eddy fluxes? Biogeochemical Feedbacks from and to the Ocean

Abstract: Marine physics influence biogeochemical systems from microscales to planetary scales. Ocean eddies are ubiquitous and highly energetic rotating features of ocean circulation. Their influence on biological and biogeochemical processes stems not only from advective transport but also from the generation of variations in the environment that affect biological and chemical rates. Eddies modulate the marine environment by vertically distributing and laterally stirring water parcels, chemicals, and planktonic organisms. The ephemeral nature of eddies makes it difficult to elucidate the overlaying mechanism of physical-biological-biogeochemical feedbacks. Therefore, the use of multidisciplinary approaches involving sampling, remote sensing, and modeling is necessary. All three aspects are woven through this presentation in an attempt to: 1) bridge long-standing scientific controversies on the signature of eddies on larval-fish distribution, 2) shed light on the transport and fate of underwater hydrocarbon plumes and surface UV filters in estuaries, and 3) build a paradigm-shift in marine biophysics; quantifying the relationship of eddy activity at the length scale of biological community aggregations, where the collective behavior and motion of marine animal might also be relevant to the large scale driven motion of eddies.

Seminars & Colloquia

Most seminars at GISS are held during the academic year, September through May.

Formal seminar presentations by visiting scientists are held many Fridays at 11:00 a.m.

Informal lunchtime presentations by NASA GISS staff take place on Wednesdays at 1:00 p.m. about twice per month.

Other special seminars occur from time to time as visitors' schedules permit.

Security Note

Regulations require that visitors arrange in advance for a building pass. Persons attending a NASA 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 late 2019) 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 in late 2020.

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.
