Jerzy Pniewski and Leopold Infeld Colloquium

On Monday, October 26, the first of this academic year Jerzy Pniewski and Leopold Infeld Colloquium of the Faculty of Physics will be held in room 0.06. Exceptionally, the seminar will start LATER than usual, at 11:30 a.m.

The lecture entitled:
"Accelerating Global Warming and Internal Climate Variability: Insights from the Ongoing El Niño"
will be delivered by:
prof. Szymon Malinowski, Faculty of Physics, University of Warsaw

The lecture will focus on the temporal patterns that characterize global warming. The pace of warming is accelerating while also being subject to fluctuations known as the El Niño phenomenon. The lecture will be illustrated with photographs recently taken by the speaker in the eastern Pacific, satellite images, and simulation results.

The lecture will be held in English.

Before the seminar, starting at 11 a.m., we invite you to informal discussions over coffee and cake in the lobby in front of room 0.06.

The dates for the Colloquia in the current academic year are:
26 X, 23 XI, 21 XII, 11 I 2027, 15 III, 5 IV, 24 V, 7 VI

We invite you to participate and send our best regards,

With best regards,

Abstract:

"Accelerating Global Warming and Internal Climate Variability: Insights from the Ongoing El Niño"

prof. Szymon Malinowski, Faculty of Physics, University of Warsaw

When analyzing plots of global surface temperature anomalies, one can distinguish variations driven by changes in the Earth's energy budget from superimposed fluctuations caused by the redistribution of thermal energy via ocean-atmosphere interactions. The latter are referred to as internal climate variability, the dominant mode of which is the El Niño–Southern Oscillation (ENSO). In this presentation, I will examine the ENSO phenomenon against the backdrop of rapidly accelerating global warming. To help the audience visualize the local expression of these global-scale atmospheric and oceanic phenomena, the presentation will feature photographs taken by the author in the Eastern Pacific in January and February 2026, alongside corresponding satellite imagery and numerical model outputs.
