📢 Exciting news: the Special Air Quality Edition of the #ConcaweReview is now available! For this edition, we are bringing three studies focused on the topic of #AirQuality. Two of the articles summarise studies conducted in collaboration with TNO which analyse the influence that some sectors have on ambient air quality in cities. The first article assesses the influence of international and inland shipping activity on atmospheric air quality in 19 European port cities, while the third article focuses on the influence of aviation activity on 6 European cities with large airports. The second article of this issue sheds some light on #Ozone, a pollutant with complex chemistry that makes it difficult to identify how its concentrations can be mitigated. The article focuses on the ‘Atlas of ozone chemical regimes in Europe’, developed in cooperation with INERIS, for which changes in ozone metrics as a result of reductions in road transport and industrial emissions have been simulated for 22 European cities.

The World Air Quality Index (WAQI) website shows the real-time air quality from more than 10,000 stations across the world. The Air Quality Index is based on measurement of particulate matter (PM2.5 and PM10), Ozone (O3), Nitrogen Dioxide (NO2), Sulfur Dioxide (SO2) and Carbon Monoxide (CO) emissions. Most of the stations on the map are monitoring both PM2.5 and PM10 data, but there are few exceptions where only PM10 is available. All measurements are based on hourly readings. https://loom.ly/uQDg3dI #airquality #airqualityindex #airpollution #WAQI

New study synthesizing coastal air-sea fluxes of carbon dioxide (CO2), nitrous oxide (N2O) and methane (CH4) in the global coastal ocean using observation-based products and ocean models The coastal ocean CO2 sink is 60% larger in ocean models than in observation-based products due to systematic differences in seasonality Coastal nitrous oxide and methane emissions offset 30%–60% of the CO2 coastal uptake in the net radiative balance #ocean #co2 #methane #climatechange #climate open access paper: Resplandy et al., 2024: A synthesis of global coastal ocean greenhouse gas fluxes, Global Biogeochem.

Our paper titled, "Dynamics of PM2.5 and network activity during extreme pollution events" has been published in npj Climate and Atmospheric Science! Sometimes environmental data is like a kitchen with full of ingredients but no recipe. Instead of getting expensive cookbooks, in this paper we are offering a network-based approach to turn air quality data into a delicious meal! The metrics derived from the approach could serve as a simple but effective measure to quantify and forecast air pollution levels. Thus, it can be used for policy-making and increasing public awareness. https://lnkd.in/ennPk4RF Many thanks to Ryan Qi Wang and Weiyu Li for all their support and contributions!

A simple yet effective way to visualise 1 tonne of CO2 to underscore the message that we really need to reduce our carbon footprint and curb emissions for us to stand a chance of not breaching 2degC of global warming.
Vice Chair of the IPCC, Professor at Department of Environmental Sciences and Policy, Central European University
Behind me you can see the volume of 1 tonne of CO2 at atmospheric pressure. It's enormous. In a few hours long flight, we can often emit that amount (per passenger!!). However, to remove that much CO2 from the atmosphere for example, with #DACCS (direct air capture and storage), you need to pump that much air 35,000 (thirty five thousand) times through a 20% efficient device (21,000 if you are 33% efficient, which we are still a long way from). Preventing emissions is orders of magnitude easier than trying to fix the problem afterwards. The installation was exhibited at the famous Science Ball in Vienna, where I represented the Central European University. #emissionreduction #co2 #science #sciencecommunication

Diana URGE-VORSATZ - with respect, showing one part of something without putting it into context is not very helpful from an educational perspective. It IS very effective if one is trying to persuade an audience using emotional or qualitative means that could unintentionally introduce bias into the explanation. The volume of gas behind you must be compared to the volume of the entire atmosphere, or the amount of CO2 emitted without the airplane. In other words - what is the impact of this incremental volume? Also, what is the alternative to that flight? Is there a fuel that does NOT emit carbon? Are you suggesting that people should not be allowed to fly? Or that there is must be a regulatory structure in place that dictates who can fly where when for what reason? If we're focusing on CO2, then shouldn't we account for the CO2 required to maintain Grid stability when injecting intermittent wind & solar into the Grid? Isn't that the only way to know the true effectiveness and cost of wind & solar? Great post & picture - it brings-up great questions! #energy #energypolicy #transportation #energytransition #windenergy #renewableenergy #solarenergy #fossilfuels #nuclearenergy #smr #carpeopportunitas!

Happy Lunar New Year!!!! Yes, reduction are prevention are simpler and more effective than fixing emissions, pollution and waste. Here are 10 fun facts and #ecological ways to #celebrate the #NewYear: 1. Lunar New Year, also known as Chinese New Year, is based on the lunar calendar, celebrated by many Asian #cultures. Ecological Celebration: Opt for #ecofriendly decorations like reusable lanterns or handmade paper crafts instead of plastic ornaments. 2. Each Lunar New Year is associated with one of the 12 animals in the Chinese zodiac. 2024 is the Year of the Dragon. Ecological Celebration: Symbolize the dragon with a #garden or #tree #planting activity to promote #greenery and #sustainability. 3. Red envelopes filled with money, called "hongbao" or "lai see," are traditionally given as #gifts during Lunar New Year. Ecological Celebration: Use #recycled paper or e-hongbao to #reduce paper waste and carbon footprint. 4. Lunar New Year celebrations typically involve #family #reunions, feasting, and cleaning to sweep away bad luck from the previous year. Ecological Celebration: #Organize a #community #clean-up or neighborhood #gardening project to promote #environmental #stewardship. 5. Fireworks are a common tradition during Lunar New Year festivities, symbolizing warding off evil spirits and welcoming #good #luck. Ecological Celebration: Opt for #ecofriendly fireworks alternatives like #LED light displays or #laser shows to minimize air and noise pollution. 6. The Lunar New Year marks the #beginning of #spring in many Asian cultures, symbolizing #renewal and #fresh starts. Ecological Celebration: Plant #trees or native #flowers in public spaces to #support local #ecosystems and #beautify the #community. 7. Traditional Lunar New Year food holds symbolic meaning, such as longevity noodles for long life and dumplings for #wealth and #Wellbeing. Ecological Celebration: Prepare #vegetarian or plant-based versions of traditional dishes to reduce the environmental effects of meat production. 8. Lion and dragon dances are performed during Lunar New Year parades to bring good luck and #prosperity. Ecological Celebration: Incorporate #recycled materials into homemade lion or dragon costumes for parade performances. 9. The Lantern Festival marks the end of the Lunar New Year celebrations, with lantern displays and activities. Ecological Celebration: Host a lantern-making workshop using #biodegradable materials like #bamboo or #recycled #paper. 10. Giving and receiving #blessings and well-wishes is an integral part of Lunar New Year customs, #uplifting community and goodwill. Ecological Celebration: Organize a neighborhood blessing tree where people can write #ecofriendly wishes for the #planet and hang them on branches. By incorporating these #ecofriendly practices into Lunar #NewYear #celebrations, we can #celebrate #ecological #consciousness #sustainably.
