April 6th | Ken Caldeira, Carnegie Institution for Science, Stanford

Coral reefs, ocean acidification, and transformation of the global energy system

Time: 3:15 PM, Room 22/23 Bundestraße 53 (ground floor)

This talk will discuss our recent field work in Australia’s Great Barrier Reef in the ocean, acidification in the broader context of the global climate system, and the need for the development of near-zero emission global energy and transportation systems.

We have conducted the first-ever experiments in which a plume of water with high carbon dioxide concentrations was allowed to flow over a natural coral reef community without any artificial confinement. Our preliminary results indicate that the carbon dioxide harmed coral reef growth by increasing the rate of dissolution of the calcium carbonate minerals that make up much of the coral reef....Read the abstract (PDF).

Insights from high-resolution simulation of cloud feedbacks

Time: 3:15 PM, Room 22/23 Bundestraße 53 (ground floor)

Cloud feedbacks are a leading source of uncertainty in the climate sensitivity simulated by global climate models (GCMs). Low-latitude boundary-layer and cumulus cloud regimes are particularly problematic, because they are sustained by tight interactions between clouds and unresolved turbulent circulations.This talk reviews cloud feedbacks simulated by high-resolution models that simulate the dominant cloud-forming eddy motions in such regimes...Read the Abstract (PDF)

An interplay of Rossby waves and gravity waves in the general circulation of the middle atmosphere

Time: 3:15 PM, Room 22/23 Bundestraße 53 (ground floor)

No Video available

The meridional circulation of the middle atmosphere is maintained by angular momentum deposition associated with waves. The summer-to-winter circulation in the mesosphere is mainly driven by gravity-wave forcing (GWF). However, GWF is not uniformly distributed, reflecting source distribution and filtering by Rossby waves...Read the Abstract (PDF)

 

 

May 18th | Dania Achermann, University of Aarhus

Changing Cultures of Climate Understanding: A historical perspective on climate modelling

Time: 3:15 PM, Room 22/23 Bundestraße 53 (ground floor)
Today, climate research is dominated by the use of computer models. Introduced in the 1950s and 60s they have since gained high epistemic authority in producing climate knowledge. As this talk will show, the emergence of climate modelling as a hegemonic research tool and the shaping of modern climate science was not a linear development but a result of a competition between various approaches from different disciplines and “cultures” within climate research...

Climate change and sea-level rise: impact and adaptation on the coast

Time: 3:15 PM, Room 22/23 Bundesstraße 53 (ground floor)

Global mean sea-level rise is resulting in a range of impacts including increased flood risk and submergence, salinisation of surface and ground waters, and morphological change, such as erosion and wetland loss. The potential human and ecosystem impacts in the 21st Century are significant but uncertain. Actual impacts will depend on a range of change factors in addition to the amount of sea-level rise and climate change, including a number of factors which are human-controlled such as coastal land use and management approaches...Read the Abstract (PDF)

Midlatitude warm ocean currents as climatic hotspots

Time: 3:15 PM, Room 22/23 Bundestraße 53 (ground floor)

The midlatitude ocean has been long believed to respond passively to atmosphere fluctuations, including remote influence from tropical variability like El Niño. Recent studies have nevertheless revealed active roles of the midlatitude ocean in the climate system. Unlike in vast areas of midlatitude ocean basins, warm western boundary currents, such as the Gulf Stream and Kuroshio... Read the Abstract (PDF)

 

 

December 1st | Valérie Masson-Delmotte, LSCE, France

From water molecules to climate - making sense of Greenland and Antarctic ice core records

Time: 3:15 PM, Room 22/23 Bundestraße 53 (ground floor)

Records of water stable isotope ratios in ice core records are commonly used as qualitative proxies for past changes in temperature and moisture source characteristics, and I have worked to extract quantitative signals.
Recent findings have emerged from new methodologies to monitor water vapour stable isotopes. They challenge the classical interpretation of ice core records as precipitation signals, and the ability of atmospheric models equiped with water stable istopes to correctly capture the spatial structure of boundary layer vapour isotopic composition in the North Atlantic.

Hurricanes and Rossby waves: Dynamics and predictability in the middle latitudes

Time: 3:15 PM, Room 22/23 Bundestraße 53 (ground floor)

The midlatitude climate is characterized by the ever-changing weather associated with the alternation of high and low-pressure systems. These surface pressure systems are associated with undulations of the midlatitude jet stream, so-called Rossby waves. Understanding the dynamics of Rossby waves is therefore fundamental to understanding the midlatitude weather.
In this presentation, we will first focus on the weather timescale. It will be demonstrated that moist processes play an important role in the amplification of the Rossby wave pattern...read the abstract.(PDF)

 

 

January 12th | Thomas Birner, Colorado State University

The changing width of Earth’s tropical belt

Time: 3:15 PM, Room 22/23 Bundestraße 53 (ground floor)

Earth’s tropical belt can be defined by the band of rainy equatorial regions bordered by the arid subtropics to the north and the south. Converging near-surface trade winds transport moisture into the so-called Intertropical Convergence Zone, a meandering front of convection that brings rain to the equatorial latitudes and heats tropical air through the condensation of water vapor. This heated air rises through the troposphere and diverges poleward into the upper troposphere of both hemispheres, eventually subsiding in the subtropics, where it dries and stabilizes the atmosphere against convection. Because of the strong latitudinal gradients in temperature and precipitation at the edges of the tropical belt, any shift in its edges could drive major local changes in surface climate...

In addition to his teaching and research, he is actively involved in public policy and in the public debate in Germany and at EU level. Until 2009 he was key climate change advisor to federal foreign minister and deputy-chancellor Frank-Walter Steinmeier.

January 26th | Sami K. Solanki, Max Planck Institute for Solar System Research, Göttingen

The Sun's Magnetic Field and Variability

Time: 3:15 PM, Room 22/23 Bundestraße 53 (ground floor)

 

The single quantity responsible for the continuing unrest and activity of the Sun is its tangled and dynamic magnetic field. It produces many fascinating phenomena, including changes in the Sun's radiative output, which has been invoked as a driver of the Earth's climate and a contributor to global change. In this talk some aspects of the magnetic field of the Sun will be introduced and a few recent advances in our knowledge will be presented. Brief descriptions of the Sunrise and Solar Orbiter missions will also be provided. In the second half of the talk, measurements and magnetic field-based models of solar irradiance variability will be outlined and some recent advances will be presented. Abstract (PDF)

February 2nd | Gerald Haug, Max-Planck-Institut for Chemistry, Mainz

THE POLAR OCEANS AND ATMOSPHERIC CO2

Time: 3:15 PM, Room 22/23 Bundestraße 53 (ground floor)

In the publication to be presented, we argue for a pervasive link between cold climates and polar ocean stratification (Haug et al., 1999; Sigman et al., 2004, 2007). In both the Subarctic North Pacific and the Antarctic Zone of the Southern Ocean, ice ages were marked by low productivity (Figs. 1 and 2, Jaccard et al. 2010, 2013). The accumulated evidence from sediment cores points to an increase in density stratification that reduced the supply of nutrients from the ocean interior into the sunlit surface in both of these regions.

"Quantifying the role of internal variability in climate change"

Internal climate variability gives rise to substantial uncertainty in projections of future climate change. One popular method for estimating the uncertainty in future climate due to internal climate variability is to run "large ensembles" of climate change simulations, in which all aspects of the experiment set-up are held fixed from one ensemble member to the next but for small changes in the initial atmospheric state ...read the abstract

"Response of the General Circulation of the Atmosphere to Global Warming"

Global warming is one of the least controversial phenomena in science. We are as sure that it is happening, and what the main cause is, as we are about almost anything. Unfortunately, this knowledge does not translate to being able to predict what will happen to the climate and weather. The thermodynamic response is well understood ...read the abstract

"Determining allowable CO2 emissions from regional- and impact-related climate targets: The role of land processes"

Global temperature targets, such as the widely accepted “2° target”, may fail to communicate the urgency of reducing CO2 emissions because they are disconnected from their implications. The translation of CO2 emissions into regional- and impact-related climate targets is more powerful because such targets are more directly aligned with individual national interests. ...read the abstract

"Dynamical Climate Perturbations and the Fluctuation-Dissipation Theorem"

Models indicate that much of the dynamical response of the atmosphere to imposed perturbations displays the same spatial patterns as those that dominate temporal fluctuations of the unperturbed climate. E.g., model responses to both increased GHGs and Antarctic ozone depletion show a poleward shift of the midlatitude jet in the southern hemisphere, ...read the abstract.
