Photochemistry in Interacting Urban and Rural Air Masses
The composition and chemistry of urban air has been studied for many decades. In the last 20 to xxx years, pregnant progress has been made in reducing emissions of volatile organic compounds (VOCs) and oxides of nitrogen (NO). Reductions in the abundance of secondary compounds, though, have been more elusive. The ACROSS (Atmospheric ChemistRy Of the Suburban foreSt) project is a framework to guide inquiry to definitively amend understanding of the impacts of mixing urban and biogenic air masses on the oxidation of atmospheric VOCs. A highlight of Across is an intensive, multi-platform measurement campaign in the summertime of 2022. It will use instruments staged on an airborne platform, a belfry in the Rambouillet Forest near Paris, and other ground sites. The information collected from this campaign volition be analyzed and studied to excerpt information virtually tropospheric oxidation chemical science mostly, simply specifically on changes observed in the situation of mixed urban and biogenic air masses.

Ocean acidification crunch and global warming observations from tropical corals
Homo induced increases in atmospheric CO2 levels are warming the Earth's ocean and besides increasing the acerbity of our shallow marine environments. This procedure, known as ocean acidification (OA), is caused by the absorption of atmospheric CO2 by the oceans and is threatening the ability of calcifying organisms to build their calcium carbonate skeletons. Our electric current understanding of the changes caused past OA in the tropical oceans is severely limited due to the lack of reliable long-term seawater pH monitoring and the difficulty in reconstructing past changes in pH and ocean chemical science in these remote environments. This project uses techniques to reconstruct by seawater conditions from long-living corals to observe the evolution of pH and carbonate chemical science in our tropical oceans. Improved multi-proxy techniques are also applied to discover sea surface temperature and hydroclimate changes over the past few hundred years to provide a historical context to our current climate crisis.

How forces inside the solid Earth directly influence irresolute body of water levels on multiple fourth dimension spams
Forces inside our planet drive horizontal movements of continents and ocean basins. These movements and their consequences (eastward.g. earthquakes, volcanism) are manifestations of "plate tectonics", a procedure driven by global movements inside the rocky drape of the Earth that resembles a form of thermal convection in a very gluey fluid. While plate tectonics is generally regarded as a 2D process involving horizontal crustal movements, it is really a 3D process. The internal forces driving horizontal motions also drive vertical displacements of the crust that are called "dynamic topography". I will discuss the cardinal role that dynamic topography plays in driving sea level changes. In particular, I explore how sea level highstands recorded during warm periods, notably Pleistocene interglaciations and the Mid Pliocene are strongly afflicted by dynamic topography. The study of geological sea level markers during these warm periods yields key insights on the vulnerability of polar ice masses.

History Matching for the tuning of climate models: Lessons from the L96 model
In the talk I'll present a tool from the Doubtfulness Quantification community that started recently to draw attention in climate modeling: History Matching also referred to equally «Iterative Refocussing». The core thought of History Matching is to run several simulations with different set of parameters and then use observed data to rule-out any parameter settings which are "implausible". Since climate simulation models are computationally heavy and do non permit testing every possible parameter setting, we apply an emulator that can be a inexpensive and accurate replacement. Here a machine learning algorithm, namely, Gaussian Process Regression is used for the emulating step. History Matching is and so a good example where the recent advances in machine learning can be of high involvement to climate modeling. I volition bear witness some results using History Matching on a toy model: the two-layer Lorenz96, and share some findings virtually the challenges and opportunities of using this technique.

Climate change in the Sahel: how might physical insight guide adaptation?
Agreement of the processes of oceanic influence that shape the climate of the African Sahel has advanced significantly in the concluding xx years. A unmarried, simple argument, independent of time scale, explains the past climatic change that manifested in the recurrence of drought in the 1970s and 1980s, and accounts for the year-to-twelvemonth predictability that is realized in seasonal-to-interannual climate prediction. The motivation for this approach to studying climate variability and change, reminiscent of the "storylines" approach in discussions of climate change, is the confidence that physical insight is critical to translating scientific noesis into practice. I propose that connecting scientific insight with the intuition that comes from lived feel provides an entry point that fosters the commutation between producer and user of climate information, and may ultimately facilitate the proactive adoption of strategies to suit to climatic change.

Genomics of plant invasion
Understanding how organisms tin can respond at unlike time scales is an essential component of deciphering the impact and long-term consequences of global modify. Genomics tools can provide information on the molecular mechanisms underlying response in a broad array of wild organisms and biologically relevant conditions. Farther, we now know that non-genetic effects tin can outcome in heritable, novel phenotypes even without variation in DNA sequence and could therefore provide an unappreciated source of response. We apply reduced a diverseness of sequencing approaches to explore the potential function of genetic and epigenetic processes in natural and controlled studies of the invasive Japanese knotweed. We employ resources developed in model plant species inquiry to inform our findings in these invasive plants. Combined, our studies will enhance our understanding of how plants respond to environment on different time scales, and become invasive.

Estimarting the climate affect of aerosol-cloud interactions from satellite observations
The result of aerosols on the properties and life time of clouds and the resulting changes in cloud radiative forcing however pose one of the largest sources of dubiousness in our agreement of climate change. Aerosol particles are needed of deject formation. They can too modulate cloud glaciation and precipitation formation. Spaceborne measurements provide u.s.a. with the all-time spatial coverage of multiple deject regimes. However, past studies were based mostly on snapshot observations. In addition, unsuitable parameters were used to represent atmospheric aerosols in such studies. This MOPGA project combines observations from geostationary and polar-orbiting satellites with novel methodologies to assess cloud development and to estimate the concentration of those aerosols that are relevant for deject formation and rapid adjustments. The talk will present the methods developed within the MOPGA project PACIFIC, show first applications, and lay out the piece of work ahead.

Bridging the depression-carbon engineering science gap ? Assissing energy initiatives for the Global Due south.
Many developing countries take made their Nationally Determined Contributions (NDCs) conditional on receiving climate finance, engineering science transfer, and capacity-building. Countries from the 'Global South' face up continued challenges in accessing low-carbon finance and technology, due to a lack of engagement from the individual sector. Technology transfer initiatives, including public-private partnerships or IPR-sharing platforms, take been suggested to bridge this 'low-carbon technology gap' and promote the technology transfer needed for free energy systems transformation. This paper assesses whether such initiatives indeed aim to bridge this gap and assist engineering science transfer, or respond to other imperatives such as climate justice or carbon lock-in prevention. Using a negative binomial regression, the paper finds that many of these initiatives focus on transferring multiple kinds of technologies to countries that are facing electricity access and governance challenges. Yet these initiatives do not all accost the key capacity-building components of noesis transfer, and countries with poor Intellectual Holding Rights (IPR) protection tend to be targeted less. Initiatives are besides observed less oft in climate-vulnerable countries. To encounter the Paris climate goals, there is an urgent need for the international community to address the low-carbon applied science gap past mainstreaming applied science transfer into merchandise and finance.

Nature-based accommodation to climate change in the Alps
Climatic change impacts need adaptation actions, especially in mount social-ecological systems, the climate change sentinels. Nature-based solutions (NbS) are a promising option to adapt to climatic change and provide multiple co-benefits for nature and people. In the project "Pathways of Transformation in the Alps" (PORTAL), we have created the commencement inventory of NbS to climatic change adaptation in the alps. Our results show a miss-friction match between the spatial distribution of NbS and the distribution of several future climate alter hazards. Moreover, the distribution of NbS doesn't fit with areas of loftier ecosystem services vulnerability, divers by the ecosystem services supply-demand ratios. Also, we take constitute that if incorrectly designed and implemented, NbS could lead to several trade-offs with different targets of the Sustainable Development Goals. Next, we volition model the co-benefits of NbS and design futurity transformative scenarios of NbS upscaling.

Oceanic Oxygen Minimum Zones: Decease zone and refuge
Oceanic oxygen minimum zones are mainly constitute on the western coasts of the continents. Here, cold, nutrient-rich water reaches the ocean surface and leads to increased plankton activity. As soon as this plankton biomass dies off, it sinks to depths and is remineralized there, a process that consumes oxygen. Since the oxygen supply at medium depths cannot completely compensate for this consumption, oxygen minimum zones with partially oxygen-free areas course hither. For many organisms, this zone is taboo, while others seek shelter here. Due to their high productivity, oxygen minimum zones are likewise regions with high angling yields. In his presentation, Dr Kiko will nowadays these relationships in more detail and hash out the influence of global change on the extent of these zones and their importance in the Earth arrangement.

Molecular means towards Carbon Dioxide Reduction
Molecular electrocatalysis are experiencing a renewed involvement since it can contribute to sustainable and energy–efficient redox chemical transformations including those involved in energy storage application such as Electrochemical Carbon Dioxide Reduction Reaction (eCO2RR). Hither we will present the correlation of remote interactions betwixt a molecular MnI-complex and different brine cations with redox potential tuning and its impact towards eCO2RR. Moreover, we present the electrocatalytic activity of a dinuclear cobalt complex towards carbon dioxide transformation to carbon monoxide in the presence of Brönsted acids. Chemical, electrochemical and spectroelectrochemical studies indicate a paired behavior of the cobalt centers, identifying CO–containing reduced dicobalt complexes that results from the electroreduction of CO2. Electrocatalytic studies revealed single–site mechanism with up to 94 % selectivity towards CO with but 0.39 V overpotential.

Impacts of climate-vegetation changes on the hydrological cycle of the Amazon-Andes transition Region
The main goal of the AMANECER project is to better understand how global warming and Amazon deforestation could affect the regional water bike. Our firs studies documented major biophysical transition in southern Amazon, involving deforestation and changes in rainfall regime. Using numerical simulations, nosotros analyzed the large-scale changes in atmospheric circulation according to a deforestation scenario in Amazonia. At large scale our analyses advise that Amazon deforestation may be related to alterations in the regional Hadley and Walker cells. Results from high-resolution climate simulation (using the WRF model up to 1km-1h), show that wet flux and precipitation in the Amazon-Andes transition zones are highly dependent of the land apply weather in the Amazon lowland. Compared to a no-deforested Amazon scenario, precipitation in the Amazon-Andes transition zone diminish in 20%-30%.

The Atlantic ocean meridional overturning circulation (AMOC) and climatic change
The Atlantic meridional overrunning circulation or AMOC – one of the central components of ocean general apportionment – is a complex system of currents that includes the Gulf Stream and the North Atlantic Electric current, which transport warm subtropical waters to higher latitudes where they sink and and so spread through the deep body of water. The AMOC modulates the climate of Europe and North America and has far reaching global impacts. Information technology is generally expected that the AMOC volition weaken or fifty-fifty collapse with the future climate change, which is a major concern. Nonetheless, the rates, magnitude and timing of this weakening vary greatly across global climate models equally different factors affect the AMOC dynamics. In this project we use global climate models to report in detail the fundamental mechanisms that control the rates of AMOC slowdown and investigate how the future AMOC weakening could affect climate.
