  Are cities on track to net-zero emissions? The side by side generation of greenhouse gas information systems.
  Metropolitan areas represent a big fraction of the global fossil fuel emissions. Supported by international consortiums, local governments play an active function in reducing GHG emissions at the local level, but tracking progress of mitigation actions is more tedious and more prone to systematic errors than previously thought. Atmospheric monitoring of GHG in conjunction with air quality networks brings a new source of information, more readily available and more comparable across cities than traditional inventory approaches. Nosotros present here the most recent successes and challenges over Paris, illustrated by the impact of two successive confinements in 2020, only also Mexico City, Los Angeles, and Indianapolis to track changes in urban emissions at various timescales.

  What's in our h2o and why can it change with climate?
  A common observation is that the chemistry of stream waters varies with discharge, something that is observed both in event-driven small watersheds and the seasonal monsoon variations in big rivers. Isotopic tracers indicate that the reactive source of the solutes varies equally well. These observations bespeak that the flow paths and reaction networks vary with time and hydrologic weather condition in the Disquisitional Zone. To unravel this complex behavior we are using a new generation of hydrologic models that permits the estimation of the non-steady land transit time distributions in a watershed. We seek to couple this information with the chemical and isotopic information interpreted through reactive transport modeling. The constraints from the hydrologic, chemical and isotopic approaches can tell u.s. near how and why h2o quality varies within a system and how this may alter with change with hydrologic forcing under irresolute climate.

  Plow off the tap! Institute traits that help to prepare for futurity climates
  Farming in the Sahel is risky because of water limitation. Climate change will only accentuate this constraint, which undermines food security in the region and impedes economic rural development. Harvests fail in dry out conditions because the evaporative demand creates an atmospheric moisture stress. Genotypes adjusted to these conditions exist and control water losses nether high evaporative demand, possibly via hydraulic restrictions at the root system level. They save water and are more than tolerant to h2o stress. Combining physiology, molecular biology, genetics and simulation modeling, we will decipher the mechanisms underlying tolerance, notice their genetic basis, and predict where these traits would be the virtually benign. The end products of the project are a better understanding of tolerance mechanisms, their related genetic regions, a predictive noesis of their effects beyond agro-ecological zones. These results volition guide and feed the crop improvement programs of our partners. Scout the replay

  Southern Sea clouds: why understand clouds where nobody lives?
  Around xl% of the time we observe shallow clouds covering the vast Southern Ocean which surrounds the Earth well-nigh entirely uninterrupted past any land. Some of these clouds organise into distinct patterns, others incorporate not only liquid water, only a mixture of liquid drops and frozen crystals. All of them reflect a discernible amount of sunlight and act like a semi-transparent parasol shading the ocean surface beneath. Nosotros explore whether the limerick of these clouds likewise as their organisational state are interlinked and how these impact the parasols efficiency at cooling Earth'south surface in this remote region of the world.

  Biological processes in the atmosphere: Furnishings on aerosol particles and clouds
  Aerosol particles can interact with solar radiation and – depending on their chemical composition – they can cool or warm our climate. In addition, they can human action as condensation nuclei on which h2o vapor condenses to class deject droplets. These latter droplets-cloud interactions represent 1 of the largest uncertainties in our current estimate of climate change. Chemical and physical processes in cloud water can modify the backdrop of aerosol particles and therefore their ability to deed as 'cloud condensation nuclei. While they merely comprise a pocket-size fraction of total aerosol particle loading, biological particles (e.one thousand. bacteria, viruses, fungi) they showroom unique properties and undergo biological modification processes that are currently not included in atmospheric models. In my presentation, I will talk over several of such processes and their model implementation, such as the biodegradation of organic compounds past leaner in deject water and cloud formation on biological particles.

  You can't manage what you don't mensurate: Air quality in urban Sub-Saharan Africa
  Ambient air pollution is estimated to cause several hundred k deaths annually across Africa. Many African cities have very limited or no air quality monitoring infrastructure, hampering urban air quality management. The MOPGA project "Make Air Quality Great Again", in collaboration with African, American, and Australian partners, has established AfriqAir, a transcontinental network of low-toll sensors and reference monitors. Over 50 devices have been deployed in Nairobi, Kigali, Accra, Abidjan, and other African cities. These sensors are calibrated to newly-deployed reference PM2.v, NO2, and O3 monitors in Abidjan, Accra, and Nairobi, and to existing monitors in Zamdela, Kigali, and Lamto. Local partnerships ensure that the sensors are well-maintained and deployed in locally-relevant sites. We are training local students and technicians to develop local capacity and ensure network sustainability. Results and learnings for future advancement volition be shared in this seminar. Watch the replay.

  Sustainable transition towards a low fossil carbon economic system in France
  Achieving the targets of the Paris Agreement requires leaving most fossil carbon resource in the basis, and even induce negative emissions. This implies using less carbon where possible (electricity-related services), and develop sustainable pathways to convert biomass- or atmospheric- carbon to hydrocarbons for the services that cannot exist decarbonized. It also implies a more circular utilize of this carbon. This seminar will talk over the on-going results of the Cambioscop project (https://cambioscop.cnrs.fr/) where a multifariousness of pathways allowing to supply, without fossil carbon, the services demanded by the French economic system in 2050 are being built, assessed, and translated into an investment roadmap.

  Tin we machine-larn the raindrop formation processes? (Speaker: Azusa Takeishi)
  Millimeter-sized raindrops in warm clouds form by condensation and numerous collisions of micrometer-sized deject droplets. Due mainly to the complication of the latter process among numerous aerosol in diverse sizes, the pelting formation processes are usually parametrized in climate models. This parameterization, however, is often a source of significant discrepancies amongst models, in terms of rainfall, cloud microphysics, and potentially resultant dynamical atmospheric condition as well. We utilize the machine-learning method to obtain a new parameterization that mimics the pelting formation processes in a detailed bin model. Although the loftier computational price makes it impractical to directly embed the bin model within climate models, this machine-learned parameterization enables the prediction of rain formation processes similar to the bin model.

  Biomass Fast Pyrolysis: Kinetics and Thermodynamics
  Large volumes of contaminated biomass considered as waste are available and not usefully used. Fast pyrolysis, a thermochemical process, is used to turn those solids into liquids that can be further upgraded to produce advanced liquid biofuels and high-value organics. Liquid yield and quality are dependent on biomass type and the temperature-time history. To ensure consequent product and high quality of those liquids, we propose to constitute a dynamic model adjustable to the conversion of different biomasses including kinetics and thermodynamics aspects. A robust methodology on a commercial microreactor combining isoconversional and plumbing equipment methods has been developed to determine intrinsic chemical kinetics. Thermodynamics is currently apprehended to predict the vapor-liquid equilibrium of the liquified biomass. This global arroyo volition be presented equally a universal alternative to non-empirical models and the use of sophisticated microreactors to optimize pyrolysis.

  Beating the Terawatt Challenge: New Materials and Interfaces in Photovoltaics
  At the cadre of combating climate change lies the profound transformation of our energy system to reduce CO2 emissions. Solar panels, or more precisely photovoltaics (PV), i.e. the straight conversion of sunlight into electricity, became a primary technology to contribute towards this goal. In the past x years, its growth rates are exceeding those of all competing technologies for power generation, and by the finish of 2020 the installed cumulative capacity amounted to more than 750 GW. Today nosotros ask: What does it take to further accelerate this growth and make PV our principal sustainable energy source on a global scale with tens of terawatt installed capacity? To this end, we are working on the side by side generation of PV panels that offer higher efficiencies at lower production costs. Key to unlocking this approach is the understanding of the fundamental chemical science and physics of novel hybrid materials that human action as light absorbers, besides as tailoring the interfaces within the device.

  Intermittency of Sunlight, sustainable photo-supercapacitors for energy conversion-storage in a single device
  Power conversion efficiencies of solar cells depends on the fluctuation of the solar cells irradiation which represents one of the main limitations of this renewable free energy resource. Integration of the solar cells with energy storage devices into single device may solve this problem because of the concomitant electricity storage. To construct such devices the supercapacitors (SCs) can be used every bit storable part considering of their benefit from the cycling stability, skillful rubber and simultaneous use of carbon plates every bit electrodes for SCs and counter-electrode of solar cell based on perovskite absorber. To obtain carbon materials for both devices, biomass waste matter can be used as a renewable source which can assistance u.s. to reduce the not-sustainable use of fossil carbon deposit. In our work, coconut shell has been selected equally biomass precursors to obtain carbonaceous materials and then applied as electrodes for SC and electrode for perovskite solar cells.

  Global tree fecundity and its contribution to xx-commencement century forests
  The limerick and construction of twenty-first century forests will depend on the seed production needed for tree populations to proceed step with climatic change. The decade-calibration trends will depend on reproduction by trees of different species and size classes across shifting habitats. Anticipating hereafter forests requires data and modeling approaches that can be used to quantify private tree responses to climate modify and how that translates to reproduction under novel weather condition and at regional scales. To accost these challenges, the Masting Inference and Forecasting (MASTIF) network, developed past the MOPGA project Forecasting Biodiversity Change (FORBIC), is allowing united states to evaluate direct and indirect effects of climate change on reproduction of time to come forests. I discuss emerging insights from private-scale processes such as demographic changes, to community consequences for mast-consuming wildlife, to global climate and soil controls on woods migration and resilience.

  Lake-rich permafrost landscapes in Siberia: Critical places at critical times
  Central Yakutia (Siberia) hosts one of the thickest, ice-richest permafrost in the world. Nearly half of the landscape has been affected by permafrost thawing since the early Holocene (~ 10,000 years ago). Increased thawing has affected the region since the final decades, potentially fuelling carbon transfer to the atmosphere through greenhouse gas (GHG) emissions. The main objective of the MOPGA project chosen « PErmafrost and Greenhouse gas dynamics in Siberia » (PEGS) is to narrate the spatial and temporal variations in GHG fluxes emitted by lakes formed by the thawing of ice-rich permafrost in Siberia. During this talk I will prove that GHG and carbon cycle dynamics in Central Yakutia can be extremely variable in both space and time, both currently and on the long-term perspective (over the last millennia). Such insights from fieldwork-intensive studies, coupled with laboratory simulations, should assist refining numerical models in order to predict future trends in permafrost evolution.

  How global environmental change affects marine biodiversity
  In this talk, I volition provide an overview of my current research fabricated possible past the 4Oceans-"Make Our Planet Great Once more" initiative, nether which my colleagues and I have focused on physiological, ecological and adaptive responses of marine organisms to ocean warming and acidification. 4Oceans takes advantages of two "natural laboratories" to study the effects of global ecology change on organisms and ecosystems: (i) highly variable seasonal temperatures and extreme marine heatwaves in the Mediterranean Sea, and (ii) a series of naturally-occurring volcanic CO2 vents, which cause local acidification of seawater, used every bit a proxy for time to come acidification conditions. We conduct field observations and manipulative ecological experiments across several unique marine vent systems, which include various habitats and depths found off the declension of Ischia, Italy, a volcanic island just n of Naples. These natural CO2 systems capture the emergent effects of ocean acidification on entire ecosystem construction, function and interactions over long time scales. This talk volition highlight instance studies in which we combine: (i) littoral oceanography (including characterization of temperature regimes, h2o chemical science and pH variability) with (ii) ecological and physiological field surveys and laboratory experiments; (three) a functional-trait based approach, where functional traits are defined as those traits that directly influence an organism'south functioning; and (iv) development of body of water-based activities to attenuate acidification, assessing the potential for marine macrophytes to act as biogenic refugia.
