|New Advances in Land Carbon Cycle Modeling
19-26 May 2018, Northern Arizona University, Flagstaff, AZ, USA
Organized by Professor Yiqi Luo.
A Mini-symposium and short training course for modelers who want to gain simplicity in coding, diagnostic capability, and computational efficiency for there carbon cycle models, and for students, post-docs and young scientists who want to learn carbon cycle modeling with CLM.
You will learn:
- New theory on land carbon storage dynamics
- Matrix representations of land carbon, nitrogen, and phosphorus cycles
- A unified diagnostic system for full understanding of uncertainty sources
- Carbon cycle data assimilation system for both flux- and pool-based data
- Semi-analytic spin-up for computational efficiency

|International Conference on Negative CO2 Emissions 2018
22-24 May 2018, Chalmers University of Technology, Gothenburg, Sweden
Organized by Chalmers with support from Global Carbon Project and International Energy Agency, i.e. IEAGHG, IEAIETS and IEA Bioenergy.
The objective of the Paris Agreement is to limit global warming to well below 2°C, and to pursue efforts to limit the temperature increase to 1.5°C. The IPCC Fifth Assessment Report quantified the global "carbon budget", that is the amount of carbon dioxide that we can emit while still having a likely chance of limiting global temperature rise to 2 degrees Celsius above pre-industrial levels.
The exact size of the carbon budget cannot be specified with high confidence since it depends on many uncertain factors, including emission pathways for non-CO2 climate forcers. This said, the remaining budgets for the 1.5°C and 2°C targets have been estimated at about 200 and 800 Gt of CO2 . With unchanged present emissions at about 40 Gt CO2/year these budgets would be exhausted in as few as 5 and 20 years, respectively. Consequently, most of the IPCC emission scenarios able to meet the global two-degree target require overshooting the carbon budget at first and then remove the excess carbon with large negative emissions, typically on the order of 400-800 Gt CO2 up to 2100.
At the same time as negative emissions appear to be indispensable to meet climate targets decided, the large future negative emissions assumed in climate models have been questioned and warnings have been raised about relying on very large and uncertain negative emissions in the future. With the future climate at stake, a deeper and fuller understanding of the various aspects of negative emissions is needed.
The purpose of the conference is to bring together a wide range of scientists, experts and stakeholders, in order to engage in various aspects of research relating to negative CO2 emissions. This will include various negative emission technologies, climate modelling, climate policies and incentives.

|Combined IG3IS/TRANSCOM workshop 2018
17-20 September 2018, Lund University, Geocenter II, Lund, Sweden
Organized by WMO-IG3IS.
The workshop is sponsored by WMO, GAW and ICOS, and it is dedicated to the use of atmospheric measurements
to improve the quantification and understanding of greenhouse gas fluxes. Like in previous TRANSCOM meetings,
its covers the full scope of methods and applications, including the use of various types of measurements
(global & regional networks, aircrafts, satellites, isotopes, etc.), and different methods (flux inversion,
CCDAS, FFDAS, etc.) to constrain fluxes and processes (land biosphere, ocean, fossil) at scales ranging from
global to local. The meeting will provide ample opportunity to discuss new developments, remaining bottlenecks,
and how to take advantage of international cooperation and coordinated joint activities to support progress.
The meeting will provide an overview of various ongoing activities and provides the opportunity to discuss
or even initiate something new.

|OCB Workshop on Oceanic Methane and Nitrous Oxide:
The present situation and future scenarios
28-31 October 2018, Lake Arrowhead, California, USA
Organized by the Ocean Carbon Biogeochemistry (OCB) program.
A three day workshop on oceanic methane and nitrous oxide covering chemical analysis, microbial metabolism, and our observational and predictive capabilities
Where in the global oceans should spatial and temporal surveys be conducted to discern climatologically-relevant changes in water-column inventories of methane and nitrous oxide?
This is an important question facing oceanographers today. However, attempts to answer this question stimulate many related and relevant queries concerning the production and consumption of methane and nitrous oxide in the ocean. For example, how will their water-column concentrations be influenced by factors such as increasing seawater temperatures, decreasing oxygen concentrations, and changing nutrient loading? Do we have sufficient analytical and observational capacity to conduct robust temporal surveys? Do we sufficiently comprehend the microbial metabolic pathways that produce and consume these two trace gases?
This workshop will address these questions to help determine the future directions of methane and nitrous oxide measurements in the global oceans.
