ITS3.2/NH10.7 Climate Extremes, Tipping Dynamics, and Earth Resilience in the Anthropocene

Extreme climate and weather events, associated disasters and emergent
risks are becoming increasingly critical in the context of global
environmental change. They are a potential major threat to reaching the
Sustainable Development Goals (SDGs) and one of the most pressing
challenges for future human well-being.
Climate change is projected to result in an increase in extreme climate
and weather events, which pose a growing threat to human well-being and
the achievement of the UN Sustainable Development Goals (SDGs). Further
warming is also projected to reduce the efficacy of carbon sinks acting
as negative feedbacks on warming and increase the risk of crossing
tipping points and triggering cascading changes in the climate and
ecosystems. These processes may reduce the Earth system’s resilience,
which has the potential to further amplify climate change and extremes
and worsen societal impacts.
Maintaining Earth in the Holocene-like conditions that have enabled the
development of the world’s societies will require better understanding
of feedbacks and tipping dynamics in both the human world and the
biophysical Earth. Societies will need to embark on rapid socio-economic
and governance transformations in order to both reduce the risk of
triggering tipping points and to improve societal resilience to
increasingly likely extreme events. Earth resilience brings the complex
dynamics and perturbations associated with human activities into Earth
system analysis, and increasingly captures socio-economic as well as
biophysical dynamics.
In this session we welcome transdisciplinary and cross-scale
contributions relating to climate extremes, tipping dynamics, and Earth
resilience, covering topics ranging from the cascading impacts of
extreme events, key feedbacks and tipping points in both biophysical and
human systems, enhancing societal resilience to extreme events, and the
potential for rapid social transformations to global sustainability.
BG3.33 Emerging constraints of photosynthesis (including chlorophyll fluorescence), respiration, and transpiration at ecosystem to global scales
Venue: Vienna, Austria
Date: May 3rd to 8 th 2020
Convener: Mirco Migliavacca; Co-convener: Markus Reichstein
Gross photosynthetic CO2 uptake is the single largest component of the
global carbon cycle and a crucial variable for monitoring and
understanding global biogeochemical cycles and fundamental ecosystem
services. Nowadays routine measurements of the net biosphere-atmosphere
CO2 exchange are conducted at the ecosystem scale in a large variety of
ecosystem types across the globe. Gross photosynthetic and ecosystem
respiratory fluxes are then typically inferred from the net CO2 exchange
and used for benchmarking of terrestrial biosphere models or as
backbones for upscaling exercises. Uncertainty in the responses of
photosynthesis and respiration to the climate and environmental
conditions is a major source of uncertainty in predictions of
ecosystem-atmosphere feedbacks under climate change. On the other hand
transpiration estimates both at ecosystem to global scales are highly
uncertain with estimates ranging from 20 to 90 % of total
evapotranspiration. The most important bottleneck to narrow down the
uncertainty in transpiration estimates is the fact that direct
measurements of transpiration are uncertain and techniques like eddy
covariance measure only the total evapotranspiration.
In this session we aim at reviewing recent progress made with novel
approaches of constraining ecosystem gross photosynthesis, respiration
and transpiration and at discussing their weaknesses and future steps
required to reduce the uncertainty of present-day estimates. To this end
we are seeking contributions that use emerging constrains to improve
the ability to quantify respiration and photosynthesis processes,
transpiration and water use efficiency, at scales from leaf to ecosystem
and global. Particularly welcome are studies reporting advancements and
new developments in CO2 and evapotranspiration flux partitioning from
eddy covariance data, the use of carbonyl sulfide, stable isotopes
approaches, and sun-induced fluorescence.
EGU Splinter-Meeting (SMI10) Emergent Risks and Extreme Events (Risk KAN)
Venue: (SMI10) Room 0.51, EGU Vienna, Austria
Date: May 8th 2020, 8:30-10:15, 10:45-12:30
Cancelled due to cancellation of physical EGU 2020 meeting
Convener: Markus Reichstein; Co-convener: Dorothea Frank
This splinter meeting is organized by and contributing to the Knowledge Action Network Emergent Risks and Extreme Events (Risk KAN)
.
The goal is to find links between the Risk KAN and related activities of
organizations and individuals. To this end we plan on targeted
contributions and follow up discussions on joint activities, in
particular also in the context of the Working Groups in the Risk KAN.
The Risk KAN provides an open platform for scientific communities from
across science disciplines and engineering working on extreme events,
disaster risk reduction and governance to exchange information,
knowledge and data and engage in collaborative research activities, as a
joint initiative of the Future Earth, IRDR and WCRP programs.
Agenda (to be refined):
8:30-10:15 Presentations of activities including envisioned links to Risk-KAN
10:45-12:30 Informal topical group discussions (funding, publications, events, projects)
19.00 - Dinner
