Did you know that forest soil contains a significant amount of carbon and plays a crucial role in the Earth's carbon cycle?🌱 Microbial decomposition releases carbon into the atmosphere as CO₂, making it essential to measure soil-surface CO₂ efflux. Researchers commonly use chambers combined with CO₂ concentration measurements for this purpose. In this blog, discover how soil CO₂ efflux is determined and the applications of soil carbon flux research, as well as the Edinburgh Sensors gas sensing solutions suitable to this application. https://ow.ly/2UIA50TiITx #SoilCarbon #CarbonCycle #ResearchTech

Good read. Now, based on the estimated height of the lady in front of this cube (1,75 m) and attempting to compensate for the distortion of the wide angle lense used, I estimate this cube to be 7x7x7 meters, or 343 m3. Currently, global CO2-emissions are at 37 gigaton yearly (a gigaton is 1 billion tons), so we emit 100 million tons of CO2 of fossil fuels and industry into the atmosphere every day! We would have to remove 100.000.000 times 343 m3 = 34 billion cubic meters of CO2 each and every day to keep up the pace. But, apparently, we’d have to pump that much air through a 20% efficient device 35.000 times, which equals an air volume of 35.000 x 34 billion = 1,2 million times a billion cubic meters of air. But that’s just for one day of emissions. To remove our yearly CO2-emissions of 37 gigatons we’d have to process 4,4 times 10 to the 17th cubic meters of air. And that’s only our yearly addítional emissions. To date, cumulatieve CO2-emissions are at 1.500 gigatons. CO2 stays airborne for thousands of years. We need to get every molecule out to reduce current global atmospheric CO2-levels from 420 ppm to safe levels below preindustrial levels of 280 ppm. Carbon capture is a delusion, a pipedream.

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

One part of the proposed decarbonisation of aviation involves removing carbon from the air around us. This exhibition illustrates the challenge in doing this.

Can we imagine the volume of giga tonnes of carbon emissions each year and the humongous challenge we have for carbon removal !!

How do Plants Uptake CO₂ from the Environment? An einstein™ Experiment Fourier's team experimented with the einstein™ Tablet with its MiLABEx software and the CO₂ Sensor to measure the CO₂ levels of leaves placed inside a sealed container. The purpose of the experiment is to test how plants uptake CO₂ from the surrounding environment through the process of photosynthesis. Photosynthesis is a vital biological process through which green plants, algae, and some bacteria convert light energy into chemical energy. This is a practical way to visually demonstrate the process of photosynthesis and its importance in CO₂ absorption from the environment, making it a relevant and engaging experiment in the context of climate change education. Watch the video to see the experiment components, setup, and results.

Such a powerful visualisation. It’s so true that we have to really change the way we work to produce less before we think about capturing/offsetting. Let’s think clever on how we produce, what we emit, the “true” cost of creating. Only produce what we need, consume less and think circular. Fix the underlying issues with holistic behavioural change and not try and band aid this. We of course need the first aid responses but let’s think about treating the underlying prognosis.

A picture is worth a thousand words, yet the invisibility of carbon emissions renders them abstract to us. In contrast to visible environmental disasters like the ongoing wildfires in Chile, the recent floods across Europe, and the back-to-back storms in Ireland, we remain detached from the pervasive issue of carbon emissions. To put this into more perspective this cube measures 8.2 meters (27ft) on each side, which overshadows the average semi-detached home. According to the most recent EPA data the average Irish person has an annual carbon footprint of just under 12 tonnes CO2eq/person. So just this year the average Irish person will generate 12 of these cubes of carbon, over a lifetime that's over 1,000 tonnes or the size of a very large housing development if we are to compare. As a visual person, I hope some of you also find this useful. Despite all the talk/technology when it comes to carbon emissions prevention is still very much better than cure!

Full agree, reducing emissions or capturing them at source is so much more efficient

💡 Interesting perspective on the use of Direct Air Carbon Capture & Storage (DACCS) to provide 'negative emissions' in an attempt to counter aviation emissions 👇

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!
